IODP Forum: Meeting #4(Shanghai, China)

CIBMarch, 201B

CIBMarch, 2018

General Purpose

The IODP Forum is custodian of the Science Plan and a venue for exchanging

ideas and views on the scientific progress of the “program”. As occasion

warrants, the Forum Chair will also provide advice to IODP Facility Boards on

Platform Provider activity:

• No specified budget (but with some support from the SSO); attendance by

representatives of partner countries/consortia at scheduled meetings is

voluntary and supported by those members.

• This phase of scientific ocean drilling is “collaborative”; in such a form,

important “program” aspects (e.g., responsiveness to submitted proposals

from the international scientific community, seeking new partners,…) can

get lost. The Forum helps to prevent that from occurring.

• Philosophical rather than political clout; however, the Forum mechanism IS

working.

The Forum meets once/year

Our most recent meeting (#4) took place in Shanghai, China, on 11-12 September, 2017:

• All Forum decisions are by consensus; items arising from the last meeting can be found at www.iodp.org/iodp-forum.

• Here, I present relevant consensus items from the last meeting and invite brief comment/discussion.

CIBMarch, 2018

http://www.iodp.org/iodp-forum

CIBMarch, 2018

Forum Consensus Item 17-02: The Forum, after receiving the results of

reviews commissioned by both the ANZIC and ECORD consortia in service of their respective renewals for ongoing participation in IODP, acknowledges the continuing need to foster the “Biosphere Frontiers” theme of the decadal Science Plan. The Forum supports a workshop-based approach to: 1.) identify new/broader components of the international scientific community to develop “Biosphere Frontier” drilling proposals and 2.) build that biosphere theme more strongly into the current flow of IODP proposals.

Forum Consensus Item 17-03: One of the Forum’s primary responsibilities is to

be a custodian of progress of IODP towards fulfillment of its decadal Science Plan. Since the inception of the Forum, its Chair (in concert with the Science Support Office) has maintained a progress report on pre-(drilling) expedition assessments (by proponents, primarily) of that progress. While results of those assessments foster optimism that progress is being made across all of the Science Plan’s themes and component challenges, post-expedition assessments have not been systematic, but are equally important for the health of scientific ocean drilling. That task will be undertaken for JOIDES Resolution expeditions during the first phase (2013-2017) of IODP by the JRAW (“Assessment of the JOIDES Resolution in Meeting the Challenges of the IODP Science Plan”) workshop, to be held in late September 2017. The Forum looks forward to the JRAW report, and urges similar assessment efforts by other IODP platform providers/component drilling communities.

• As of submission of this presentation, the JRAW report was not yet available, but should be out “soon”.

CIBMarch, 2018

Forum Consensus Item 17-04: Taking into account the generally

acknowledged validity of IODP’s current decadal Science Plan for the next ~5-year phase of scientific ocean drilling, and after extensive discussion following a forward-thinking presentation by a representative from China, the Forum endorses a long-term (multi-year), workshop-based approach to assess the technologies needed to reach the full potential of that Science Plan. Those workshops, to be held beginning in ~2019, should incorporate: 1.) the diverse challenges inherent in a multiple (drilling) platform approach to addressing the Science Plan, 2,) the importance of inclusion of both member and non-member scientific communities, as well as industry, in order to build scientific ocean drilling’s constituency, and 3.) interest expressed by China and other IODP members and consortia to lead this effort. Ideally, this initiative should be progressed in parallel with any and all (new and ongoing) planning efforts designed to keep IODP as presently constituted alive and well.

CIBMarch, 2018

CIBMarch, 2018

Forum Consensus Item 17-05: The Forum applauds the initiative expressed by the group pursuing a commemorative volume in the journal Oceanography entitled “Scientific Ocean Drilling: Looking to the Future”. This publication will form both a commemoration and a celebration of 50 years of scientific ocean drilling; the volume is expected to be published in time for the anniversary, ~December 2018. The Forum sees this activity as emblematic of a range of activities which could and should be pursued, both to honor this milestone and to support the productive continuation of IODP beyond 2018.

• Anthony Koppers (Chair, JRFB) is the lead editor; more details can be gotten from him.

CIBMarch, 2018

Forum Consensus Item 17-06: The Forum is encouraged by activities in support

of its Consensus 16-06 over the past year in support of both publicizing and supporting the crucial relationship between seismic imaging/drill-site characterization and scientific ocean drilling, across all platforms. However, the risk of a reduction in seismic imaging capabilities internationally remains. The Forum notes that the efficiency of JOIDES Resolution (JR) operations within this phase of IODP has been improved by multi-year regional planning; recently, the primary seismic imaging asset of the U.S. has been operated productively in a similar way. The Forum suggests and supports development of a planning effort linking seismic imaging and drilling, through workshops, with emphasis on likely future areas of anticipated IODP operations. The primary goal is to support seismic imaging efforts in support of and en route to development of competitive proposals to drill all accessible parts of the global ocean system, during the next phase of IODP.

Forum Consensus Item 17-07: The Forum receives multiple reports

from IODP member countries and consortia concerning “education [E] and outreach [O]” activities in support of scientific ocean drilling. Those activities are diverse and in many instances inspiring. However, at the same time, they are generally underfunded and dispersed, which is accentuated by both inherent cultural and language differences across the IODP membership. Education activities generally focus on development of curricula, whereas outreach activities broadly target the general public. A recent ECORD program review suggests a renewed emphasis on outreach efforts. The Forum encourages these outreach efforts, particularly those that can be generalized across the IODP to enhance efficiencies. A long-term objective is increased decoupling of “E” vs. “O” activities, with emphasis on those IODP efforts that lead to measurable impacts.

CIBMarch, 2018

Forum Consensus Item 17-09: The Forum enthusiastically

accepts the invitation from our Indian colleague Brijesh Bansal to hold the next meeting of the Forum (#5) in Goa in September 2018 (exact dates to be determined). Japan has offered to host the Forum #6 meeting in Osaka in September 2019. The Forum greets that invitation with equal enthusiasm.

• The search for the next Forum Chair is underway (application deadline 1 March). The review committee has been named, and an acceptable candidate should be in place in time to attend the Forum meeting in Goa.

The JRFB reaffirms its primary goal of implementingall proposals that are thoroughly reviewed, scientifically evaluated, and forwarded by SEP and that have been recommended for approval by EPSP.

Decisions on scheduling are principally dependent on the planned regional track of the JOIDES Resolution; maximizing the fit and balance of proposals to the IODP 2013-2023 science plan; funding and ship time availability; and safety, permitting and other logistical constraints.

NSF/OCE/ODP Report to ChikyuIODP Board

March, 2018 Meeting

Kobe

NSF Budget

• President’s proposed FY2019 NSF budget same as actual FY2017 ($7.5B)– Congress sets actual appropriation– Proposed FY2019 OCE/ODP funding same as actual FY2017– 2018 budget not yet set but likely flat

• Financial situation for JR appears stable– FY2018 APP JRSO budget is $66.8M

• 10 months planned operations for both FY2018 and FY2019• Icebreaker support for JR operations is $1M additional (NSF/ODP pays)• Expensive year…

– International Contributions to support FY2018 JR operations• $14.7M base contribution• South China Sea CPP Funds are a big help!

JR Facility Review

• 5-year Cooperative Agreement for JR operation requires annual and mid-award (3rd-year) reviews

• Reviews used in determination for renewal or re-competition of Cooperative Agreement, and for “mid-course” corrections– Are confidential and cannot be posted– NSF response is public

• NSF Panel met at JRSO February 28 – March 2, 2018 for FY2017 Review – U.S., European panel members– Received report from FY2017 co-chief review, held

February 26-27

JR Facility Review Panel

• NSF selected Panel, in consultation with JRFB Chair and JOIDES Resolution Science Operation– 9 panelists, including Chair– 2 JR FB members– Facility experts within and outside scientific drilling– NSF pays panelist costs; panelists subject to NSF COI rules

• Panel Review and Scope follows NSF Large Facilities Office (LFO) Guidelines for Review of Large Facilities and the NSF JR CA Internal Management Plan– Report is to NSF– NSF ODP and IPS Management attended all proceedings– Operates under Federal Advisory Committee Act (FACA) and Freedom of

Information Act (FOIA)• Part- Closed Meeting (Executive Sessions)• Open sessions included input from JR FB Chair (Koppers) and IODP Forum Chair (Austin)• Report is Confidential; will be shared with NSF Financial Partners and JRFB

Panel Report and NSF Response

• NSF was pleased to receive the Executive Summary that states – The JOIDES Resolution (JR) is a unique scientific research facility that permits Earth

exploration and hypothesis-testing globally to tackle large-scale problems at the frontiers of our knowledge. No other platform offers its range of capabilities. The JOIDES Resolution Science Operator (JRSO) continues to perform the tasks of technical and scientific support to the world-wide research community in outstanding ways. The JR is an exceptional platform for research collaboration, with an outstanding track record of safety and operational efficiency that forges the development of international teams with diverse expertise that creates an enduring legacy. The JRSO Site Visit Panel concludes that the facility is being managed superbly well by the JRSO, with effective support from the JOIDES Resolution Facility Board and NSF, to meet the international scientific communities’ Science Plan.

• Panel Report gave both 3 challenges and 10 recommendations– No significant shortcomings identified

• NSF impressed with the Panel report and will write a response soon

JR Staffing

• 10 U.S. Party members on JR Expeditions– includes Onboard Outreach Program members– Will increase in FY2020

• Those sailing under Onboard Outreach Program are members of the Expedition Party– In shipboard party chain of command with Co-chiefs, EPM’s

• Future Memoranda – Increase from $3M to $4M for full membership in JR Consortia

• NSF would prefer minimal changes in language, Facility Board and panel membership numbers

• NSF and ECORD agree on financial, staffing details

– Co-chief scientists and Onboard Outreach members will be included in total quota rights- will treat all JR berths equally

JOIDES Resolution Facility Renewal

• NSF GEO Directorate will make decision soon as to whether to pursue facility renewal

– 5-year is standard renewal (FY2020-FY2024)

– National Science Board approves authorization for expenditure of funds for facility renewal, does not approve IODP Program

• Too early for NSF to speculate on post-International Ocean Discovery Program, including platforms or program(s)

Highlights from the SEP Terms of Reference

INTERNATIONAL OCEAN

DISCOVERY PROGRAM


Watchdog Preparation

of Proposal Reviews

WD1 Science presents the science case of the proposal after

consultation with the other assigned WDs

WD2 Science advises the WD1 on the science case, and records the

science part of the response letter to proponents (together with WD1)

WD3 Site presents the new site survey data after consultation with the

other assigned WDs, unless there are no new data. If no data, then WD3

advises on data that are necessary.

WD4 Site advises the WD3 on the site survey data, and WD4 records the

site survey part of the response letter to proponents (together with WD3).

WD5 Operator advises watchdogs 1-4 on the drilling plan, platform,

technical issues and feasibility of the proposed program.

INTERNATIONAL OCEAN

DISCOVERY PROGRAM

SEP report to CIB 3/18Review Procedures:

Characterizing the Site Survey Data

The Science Evaluation Panel (SEP):

•Advises proponents on data that are deemed necessary

•Reviews all data in the Site Survey Data Bank (SSDB)

•Advises the proponents on the adequacy of the drill site

characterisation package

•Provides an assessment of whether or not the scientific

objectives of each drill site can be effectively achieved on

the basis of the proposal and data package

Based on the data that are presented, can we be

reasonably assured that they can achieve their objectives?

INTERNATIONAL OCEAN

DISCOVERY PROGRAM

SEP report to CIB 3/18Site Classification System

Hinges on whether WDs feel that the data reviewed: Are sufficient to support drilling (i.e., objectives are likely to be

achieved, and there are no, or minimal, scientific concerns).

Are not sufficient to support the drilling (i.e., targets are not imaged properly, data are not annotated properly, sites are mislocated, more data are needed, data are not interpreted correctly, structural complications, etc.).

Given the data, are they drilling in the right locations and to the right depth to achieve the scientific objectives.

5 No data have been reviewed by SEP

Data reviewed by SEP are insufficient to support the drilling effort, and additional data are not believed to exist

Data reviewed by SEP are insufficient to support the drilling effort, but other data are believed to exist; and/or data are not annotated or organized sufficiently to fully review, or there are scientific concerns

Data reviewed by SEP are sufficient to support the scientific objectives of the drilling effort and there are no further concerns

Data reviewed by SEP are sufficient to support the scientific objectives of the drilling effort, but minor concerns require follow-up by proponents (specify in text)

“Insufficient“ indicates that the data package is not sufficient to convince the SEP that the scientific objectives can be

addressed. For example: 1) the data package may lack items that are fundamental to determining the correct site

location or target depth; 2) the data may be of insufficient resolution to demonstrate the existence of targeted strata; 3)

the data may not demonstrate unequivocally that the proposed locations are correct (e.g. sites are not plotted correctly

or mismatches exist between navigation files and proposed locations); 4) site locations are deemed to be inadequate

for addressing the objectives (e.g. missing critical sections, misinterpretations, science or safety concerns, etc.).

“Minor concerns” may include missing items or questions that do not affect the assessment that drilling is warranted at

proposed sites, meaning the objectives can be met based on existing data despite the concerns. Examples include: 1)

missing image files (e.g. bathymetry); 2) minor issues with velocity that may slightly affect the proposed depth of

penetration; 3) minor navigation issues. These can be addressed while proposal resides at the FB.

We aim to drill through deep oceanic crust and the Moho into

the uppermost mantle beneath the Bonin fore-arc in the NW

Pacific. The goals are to understand the origin and evolution

of supra-subduction zone crust, the nature of the Moho, and

the geochemical and geodynamic evolution of recently

accreted lithospheric mantle. (M2M = Moho to Mantle)

898-Pre SEP1606

Hypotheses

Hypothesis 1: Petrology – Peridotite and gabbro preserve records of

melt-mantle reaction during subduction initiation and information about

the accreted asthenospheric mantle.

Hypothesis 2: Tectonophysics – Peridotite records the structural

history of subduction initiation, ocean lithosphere formation, and

subsequent deformation.

Hypothesis 3: Fluid and Hydrology – Serpentinite in the fore-arc

mantle to mantle-crust boundary records hydrology and chemistry of

the subduction fluids during and shortly following subduction initiation.

Hypothesis 4: Biosphere – Circulation of subducted fluids in the

mantle and crust and their boundary (Moho) generates an unusual

deep biosphere.

898-Pre SEP1606

Differences to M2M and connection with IODP

Science Plan

objectives differ from those of the M2M projects aimed at mid ocean ridges

Focus here is on:

subduction initiation

physical, chemical, and biological interactions between the mantle,

crust and surface environment in a supra-subduction zone setting.

They address the IODP Science Plan Challenges 8, 9, 10 and 11 in the

EARTH CONNECTIONS theme and Challenges 5 and 6 in the

BIOSPHERE FRONTIERS theme.

898-Pre SEP1606

Previous attemps to drill mantle in IODP

Exp. 304 and 305 (Atlantis Massif, MAR) recovered gabbroic rocks

Exp. 360 (SWIR) drilled into a gabbroic body; deepening of the hole in

future may reach crust/mantle boundary

898-Pre SEP1606

Proposed Sites

Water depths all >6500 m

898-Pre SEP1606

Exciting science

Important information how an ocean floor developed into a mature

subduction zone

Evolutional change of magmatic event should be recorded in

ultramafic rocks

Continuous samples of gabbro and peridotite/serpentinite will

address the nature of Moho

Samples of gabbro-ultramafic rock boundary, serpentinized

peridotite and fresh (~ 50 Ma) peridotite boundary

Insight into microbial communities of the serpentine

Complete the transect started with Exp. 352

898-Pre SEP1606

Challenges and open questions

Perodotites have been recovered only from one location along the

transect

Unspecific regarding methods for testing hypotheses

Limited site survey data available

Thickness of sediment cover is unclear

Chikyu is at its technical limits with a 100m hole in 8000 m water

depth

Questionable logging plans

Science objectives are not well

represented in PI expertise

Only 1 out of the 20 proponents comes from outside of Japan

898-Pre SEP1606

Panel Decision

Request Full proposal June 2016

The proposed drill sites are in very deep water (more than 7000 m: FM-

03A and FM- 04A) and are thus quite challenging because re-entry is not

possible due to technical limits of the Chikyu. SEP suggests considering

possibilities of drilling multiple sites at shallower-water depth if the science

objectives can be achieved there as well.

Although proposed operation is within DV Chikyu’s capability, it is

expected to be a challenging operation; thus, time estimates for coring

and logging should be made in consultation with the operator, CDEX.

Lead proponents


Overall scientific objectives

Controlled triggering of earthquakes of various sizes with

associated observations of local fluid and elastic properties will

contribute to a better understanding of the stress conditions and

initiation processes of induced and natural earthquakes.

To obtain fault-zone samples of an oceanic transform and

measure physical properties, such as frictional strength and

permeability. Relating these fault zone properties to the spatial

and temporal occurrence of the earthquakes, can provide new

information about the physical mechanisms of earthquake

initiation and rupture for both induced and natural earthquakes.

1974 in the Rangely

that increasing

subsurface water

pressure triggered

earthquakes

critical threshold

pressure level (dotted

line) of 3700 psi (25

MPa)

largest earthquakes M3.1Raleigh et

al., 1976


Details of Scientific Objectives

What are the amplitudes and timing of stress changes that trigger

earthquakes?

• is there a unique pressure threshold?

• what controls the time delay between stress change and

earthquake?

Where will earthquakes occur?

• how important is the complex fault zone hydrological structure for the

location of the earthquake?

What will be the size of the triggered earthquakes?

• how do pressure level and/or water volume affect the magnitude of

the induced earthquake?


How do earthquakes nucleate?

• how do pressure level and/or water volume affect the

magnitude of the induced earthquake?

What are the differences between small and large earthquakes?

• are there resolvable differences in the initiation process between

small and large earthquakes?

What are the fault zone frictional and hydrologic properties?

• how do physical properties control seismic and aseismic deformation

and slip?


Fluid injection and monitoring

water injection

• pump water into the seismogenic zone of an active fault to change in situ

stress field

• pumping pressure and volume provided by Chikyu are sufficient to trigger

earthquake

3D site survey

• needed to characterize fault zone architecture and properties

geophysical monitoring

• seismometer (OBS), borehole pressures (CORK), borehole strainmeter and

seismometer, geodetic measurements at the seafloor

core analysis

• mineralogy, physical properties, permeability, micro-scale characterization of

structures, deformation experiments …..


Site selection criteria for a marine site

site with known history of repeating moderate to large earthquakes

hypocenter has to be within drilling depth

high level of seismicity for small events and active foreshock sequences for

larger earthquakes

logistical considerations water depth, helicopter distance to land < 350 km)


• Red and blue arrows:

locations for two

sequences of repeating

M6 earthquakes,

recurrence intervals ~

14 years.

• Yellow and gray bars:

expected occurrence

time; red and blue

circles: actual time of

the earthquakes.

• next earthquakes are

expected in

approximately 2022

and 2026

• Bottom left: probability

for a (naturally

occurring) M6

earthquake occurrence

over the next 20 years.


Preliminary time estimates for operations by Chikyu operator

2 x 24 days of transit

120 days on site (drilling 1500 m into basement, includes

pumping for 4 weeks)

168 days in total


Safety and societal aspects

offshore sites of triggered earthquakes at a distance of 350 km from

land are no danger for population in Oregon

triggered earthquakes during pumping not dangereous for drillship

strike-slip earthquake minimizes the possibility of generating a

tsunami

outreach and eductional efforts will be extremely important if project

goes forward


Strengths

scientifically very interesting and an innovative and

forward looking experiment

unique opportunity to induce a M6 earthquake in a

marine setting without putting somebody at risk

monitoring fluid injection response (during and post)

would help to learn a lot about the nucleation of an

earthquake in such a setting

in line with IODP Science Plan


Weaknesses

proponents want to trigger eq by drilling into the seismogenic

zone of an active fault and pumping water into the fault zone,

however hypocenters of M6 eq are at 4 – 9 km depth

proponents ignore the complex structure of the fracture zone

which may have important consequences for the experiment

proponents do not take the thermal regime of the Blanco FZ into

account


SEP recommendation

SEP encouraged the proponents to submit a Full proposal

CIB will discuss the pre-poposal at the March 2018 meeting

CIB has the option to invite for a workshop to develop a Full proposal

As realtime monitoring during the injection phase is absolutely

necessary partners have to be found to cover (or share) this

operation and associated cost


866-Full2 Japan Trench Paleoseismology, StrasserTRACKing past earthquakes in the sediment record along the Japan Trench: Testing and developing submarine

Paleoseismology in the deep sea (JTRACK-Paleoseismology)

Submitted as MSP; in external review; possible Chikyu role

O-1: Identify the sedimentological, physical, chemical, and

biogeochemical proxies of event-deposits in the sedimentary archive

that allow for confident recognition and dating of past Mw9-class

earthquakes vs. smaller earthquakes vs. other driving mechanism.

O-2: Explore the spatial and temporal distribution of such event-

deposits to investigate along-strike and time-dependent variability of

sediment sources, transport and deposition processes, and stratigraphic

preservation.

O-3: Develop a long-term earthquake record for giant earthquakes.

O-4 (secondary): Exploit the spatio-temporal inventory of sedimentary

event-stratigraphy towards determining sediment and carbon flux of event-

triggered sediment mobilization to a deep-sea trench and its influence on

the hadal environment.

O-1 and O-2 are related to the mission of testing and developing

submarine paleoseismology to produce robust long-term records as

input for addressing O-3 and O-4.

866-Full2 Japan Trench paleoseismology

Objectives

A good proponent team, range of expertise, past subaqueous

paleoseismology expertise, and careful, rigorous sedimentologists

Responded well to previous SEP comments

Science questions/ hypotheses are exciting and of wide interest

Proposal will significantly advance goals of Science Plan

Japan trench has great potential to really test and develop this technique –

utilizing the record from a known event. The earthquake (subduction zone)

community is excited about the potential of what we can learn at this

margin

866-Full2 and recently published work shows the team looking at the detail

and different techniques that can be applied here to increase confidence in

correlation of records between sites

Proposal’s Strengths

From previous SEP review: Still somewhat unclear how they

will differentiate different types of earthquake. Will they be able

to distinguish shallow large slip events (like 2011) and other

triggering mechanisms?

Proposal’s Weaknesses

Only the shallow large events leave sedimentary records

broadly correlated along the axis of Japan Trench.

The hypothesis will be tested (O-1 and O-2) of this expedition.

Verification of the hypothesis will allow reconstruct the history

of past giant EQs (O-3).

could be odne with

JR

drill two holes (GM-01A = ~100 mbsf; GM-

02A = ~200 mbsf) & no alternate sites !

RCB coring & wireline logging


Rationale

• A significant fraction of the ocean floor is created in back-arc basins, where

crust and mantle likely differ significantly from that formed at major ocean ridges

(expected to be contaminated by slab-derived melts & fluids).

• Oceanic Core Complexes represent a significant fraction of crust accreted at

major ocean ridges (MAR, SWIR).

Drilling : architecture of heterogeneous crust,

“window” on mantle & lower crust, hydrothermal fluxes …

• Back Arc Crust ?

Same variations in structure along ridges as

observed along MOR, e.g. Oceanic Core

Complexes

First drill hole into Back Arc OCC

Challenge/confirm ophiolitic models?


Godzilla Megamullion: the best studied Back-Arc OCC

The largest known OCC (~125 km × 55 km)

Variation of melt supply over time


Godzilla Megamullion : the largest known OCC

* combination of spreading rate and magma supply required for core complex

formation was continuously present for a far longer time than at other ocean

spreading ridges;

* occurrence in a back-arc basin; i.e., the presence of water in the mantle

lowers the effective viscosity of the peridotite in the detachment fault root

zones, reducing the effect of normal stress on the fault.


Scientific Objectives – Questions to be addressed by drilling

• 1: How does mature back-arc spreading mantle, …, compare to that found at slow-

spreading ridges? Can we see the influence of subduction zone fluids on the mantle-

melting regime there?

• 2: How does the crustal architecture evolve with changing melt supply rate?

• 3: Is the crust formed in a mature back-arc basin directly equivalent to that formed at

slow spreading ocean ridges, or does it have unique components not found at the

latter, but frequently seen in ophiolitic crustal sections presumed to have formed in an

arc-related setting?

• 4: How does back-arc basin lower crust compare as source rocks for hydrothermal

vents and massive sulphide deposits to those exposed at slow spreading ocean

ridges?


IODP Science Plan 2013-2023

• Challenge 8: “What are the composition, structure, and dynamics of Earth’s

upper mantle?

• Challenge 9: “How are seafloor spreading and mantle melting linked to ocean

crustal

architecture?

• Challenge 14: “How do fluids link subseafloor tectonic, thermal, and

biogeochemical

processes?

Summary

WeaknessesStrengths

Why Chikyu & why drilling plan?

Why only three weeks?

How were chosen these depths?

Narrow petrologic focus: Feedback needed

from hydrothermal studies and possibly

microbiology

Need to emphasize regional and global

importance

How will drilling advance understanding of

the mode of mantle melt extraction and

mode of lower crust accretion?

What methods will be employed to

distinguish subduction influence on crust

formation in the backarc setting?

• First site drilled into Back-Arc

OCC

• Clear scientific objectives in

relation to IODP Science Plan

(Ch. 8, 9 & 14)

• Questions and hypothesis can

be tested realistically by drilling

• Extended survey data

Rated more than “GOOD” except IT service.

In particular,

Shipboard curation was rated highThe workshop participants appreciated lab curator and lab tech support for personal sampling.

IT service was rated lowIn addition to internet connection issue, Wi-Fi to connect shipboard server was quite unstable. The participants faced difficulty to access/share files stored in the shipboard server.


Recommendations for the future workshop at sea

• To be distributed prior to the workshop General outline of schedule/plan Pre-cruise meeting (via web conference) Bibliography of the target sites Scanned images of working halves

• To be improved or solved Wi-Fi and internet connection Book collection for subduction zone Low-priced software (instead of very expensive Petrel) for

scientists to do seismic interpretation

ANISOTROPIC BREAKOUT

Anisotropic Breakout Findings• While drilling no tendency of breakout

– no drilling parameter change– no break out indication in resistivity image

• Hole instability is found after wiper trip (No pumping period)• Huge breakout occurs at once.• Pack off event accelerates the hole instability.• Magnificent increase of cuttings after the severe pack off event.• Once disturbed, it is hardly recover the section by hole cleaning.• It results in shallow set of 13-3/8”CSG and 11-3/4”CSG.• No pre-warning sign while drilling even passing the hole stability limit.

Countermeasures• Maintain mud weight as high as possible

– 1.42-1.46sg←1.28sg@4890mBRT(11-3/4”csg shoe)

• Shorten the section length– 600-800m / section

• 17”OH: 1470m / 13-3/8”CSG: 1150m• 12-1/4”OH: 1122m / 14-1/2”OH 1024m / 986m

• Continuous circulation system– Maintain static bore hole pressure

• Realtime Geomechanical Model• VSP / Sonic

– Damage zone Elevation / Rock strength– Velocity– LWD Image repeat section

• Vibration: – BHA vibration simulation– Harmonic tool

• Mud – Sealing Agent (10/20/70-300 μm)– Control mud pH <10– Reduce lubricants / polymers / Hivis mud– Maintain low shear rate vis = hole size (in)

• Hole Cleaning– Fiber Sweep Agent– Continuous Circulation

• Slick drill out cement assembly

Well Integrity

• Running and Cementing– Surge / Swab : <15m/min– Cementing:

• Adjust MW• Reduce Flow Rate• Conduct Cement with leaking at previous cement shoe• Control pumping fluid density

• 9-5/8”CSG tie back is inevitable– Burst:

• Require 9-5/8”tie back casing for kick event at the last open hole (worst case pore pressure 1.85sg)

– Collapse• Require 9-5/8”tie back casing for total loss event at the last

open hole (Well can endure in 1.08sg total loss)

• Well Control– No problem with 1.85sg kicks– Shoe strength shall be considered

• Extended leak off test– Two size of packer will be prepared for high pressure

EXLOT.– But there shall be the limitation of well integrity.

MET OCEAN AND SUBSEA ISSUES

Kuroshio Large Meandering

• This large meandering occurs after 12yrs absence from Sep 2017.

• Recent one large meandering period is 1-2yrs.• Global warming tends to increase the force of

Kuroshio current from West to East and difficult to occur large meandering.

MetOcean• Typhoon

– EXP338: Non productive time (10/9 – 10/19 due to typhoon: 10days)

– EXP348: Non productive time (9/11-10/26 due to typhoon: 45days)

– EXP358: Non productive time (10/10-10/26 due to typhoon: 16days? / estimation)

– Operation commencement will be from 10th Oct 2018

Contingency days are only 33days

• Most of contingency will be consumed only for typhoon / cold front / riser operability

• Other Uncertainty: Anisotropic Breakout / Riser Operability due to High Mud Weight.

Typhoon in November.

• Current and Cold Front with High Tension for High Mud Weight

– It might have a similar impact as experienced in EXP348 (low current)

Estimated rough impact

– 15days in meandering period (low current @ site)

– 28days in non meandering period (high current @ site)

Number of disconnect can be reduced by meandering.

Riser High Tension Impact• High Tension Impact on EDS

Tuned the recoil valve control

• Riser parted incident with High Tension

Speed trigger limit is modified with top stroke ramp down

• Total Loss Impact with High Tension

Full mud evacuation is critical to the riser.

• Well control situation with High Tension

The loss of position while well control situation creates the significant risk to the riser.

TAT Consensus 0218-03: CDEX Technological Developments

TAT was very pleased about the progress in ongoing CDEX technology developments:

• Newly developed Running Tool (patent pending), consisting of a Drill Ahead Tool + Activation Kit for deep water (>3,000 m) operations;

• Underwater TV system that was successfully used during Expedition 380 and is related to the operation of the new running tool;

• Long Term Borehole Monitoring System, which was successfully deployed during Expedition 380;

• Non-Stop Driller that allows borehole pressure to be maintained during addition of pipe sections etc., which will be critical for the implementation of Expedition 358 through maintaining the integrity of the C0002 hole;

• Turbine-Driven Coring System, which will be deployed during Expedition 376 to Brother’s Arc to improve core recovery in relatively high temperature hard rock drilling; (CIB Agenda Item 12.b)

• Carbon Fiber Reinforced Plastic (CFRP) Riser development, which has undergone tensile strength testing of a 1/5 scale model 6 times, and now has funding for similar testing of an actual size riser model.

TAT was impressed that several of these new technologies have been or will be implemented and may have applications in industry, and applauds the cooperation with the JOIDES Resolution Science Operator in the upcoming Expedition 376.

TAT Consensus 0218-06: Lord Howe Rise PreparationsTAT was pleased to note the extensive work carried out by CDEX in collaboration with Geoscience Australia to mature the business case for the Lord Howe Rise Project. In particular, CDEX having acted on the advice to treat the proposed expedition primarily as a logistics project, TAT commended the quality of the work done so far on options for logistical support, including crew change arrangements and identifying available choices for medical evacuation. TAT advises caution in basing the proposed mud weight program on seismic data alone. CDEX could consider reviewing the data from Site U1506 with a view to constraining the regional stress environment to reach a preliminary determination of mud weight. Attention is drawn to the active intra-plate seismic activity in the area, which implies a high differential stress environment.

TAT Consensus 0218-05: Exp. 358 DWOP-prime or DWOP’

NanTroSEIZE Expedition 358 (riser drilling to deepen C0002 to the megasplay fault at ~5200 mbsf) represents one of the most ambitious and technically challenging projects ever attempted in either industrial or scientific drilling. TAT strongly endorses the concepts presented at this meeting for (1) activating a real-time geomechanics (RTG) team before and throughout Exp. 358 primarily to advise the CDEX drilling team, and (2) conducting a carefully focused drilling the well on paper (so-called DWOP’) exercise in summer of 2018. The rationale for these two concepts is summarized in the attached statement from insight GeoMechanics (iGM). Forming, training, and implementing the RTG and defining the scope of the DWOP’ by themselves represent a significant new approach that should be of major benefit to future riser drilling projects (science or industry). Therefore TAT recommends that CDEX identify as soon as possible an experienced project manager to focus solely on defining and implementing the RTG and DWOP’ from the present through the aftermath of Exp 358. TAT members stand ready to assist in helping to define the type of expertise required for both the RTG and DWOP’ and potential nominees to serve on each.

TAT Consensus 0218-04: Exp. 380 Operational Review

TAT commends the success of the recently completed Expedition 380 that installed the Long-Term Borehole Monitoring System at Site C0006. Despite issues with releasing the Drill Ahead Tool and the LTBMS, issues with the LTBMS testing system, and the failure of the bi-center bit for drilling out cement, the expedition finished 17 days ahead of schedule. Based upon the experience gained, TAT urges the update and implementation of a best practices document for 3rd

party tools used on the Chikyu.

TAT Consensus 0218-07: M2M Task Force Team

TAT endorses the recent formation of the CDEX M2M Task Force Team (M2M-TFT) to focus technical and engineering planning for an eventual full penetration to mantle. This is consistent with previous TAT consensus statements suggesting formation of a mantle project working group, for a staged approach to achieving eventual full crustal penetration, and for exploring all technical options to the drilling challenges. TAT encourages CDEX to involve representatives of the JRSO in the M2M-TFT as appropriate, and to consult with the scientific community associated with deep ocean crustal drilling to date. (CIB Agenda Item 12d)

TAT Consensus 0218-08: Next TAT Meeting

The main focus of the next TAT meeting should be an operational review of Expedition 358; additional agenda items should include planning for Lord Howe Rise, the Mantle Project, and TDCS progress. This meeting is tentatively scheduled for the week of June 3-7, 2019. TAT asks CDEX to consider whether TAT members should be involved shortly before Expedition 358 in review of the output of the DWOP’ recommended in TAT Consensus 0218-05.

TAT Consensus 0217-011: Lord Howe Rise Future Project

• LHR is a complex project that should be organized using a standard industry five-step process: appraise, select, define, execute, operate.

• LHR is now in “appraise” phase - need to document all potential sites, possible operational strategies, risks and opportunities.

• Given remoteness of LHR (750 km from Noumea, 800 km from Brisbane), this will mainly be a logistics project. (Drilling itself is not expected to be unusually difficult.) Overall scope and cost needs to include 4 elements: Chikyu, logistics rig between site and Chikyu, helicopter based on logistics rig, supply vessels for both Chikyu and logistics rig.

• Industry will be interested in stratigraphic test results and should be engaged by CDEX and GA for potential financial support.

• To attract industry support, a stratigraphic modeling effort based on existing 2-D seismic data should be contracted.

TAT Consensus 0217-012: Mantle Drilling Future Project

TAT reiterates its two 2016 Consensus statements regarding (1) the importance of the development of the CFRP riser for the ultimate goal of a full crustal penetration, and (2) a staged approach including initial development of drilling and coring systems and verification in appropriate test holes, riserless pilot hole drilling at the actual site, and finally riser drilling to full depth. TAT commends CDEX for the initial development efforts of the CFRP riser carried out with only modest funding, and supports the plan to continue this effort with two specific goals by the end of JFY2018: developing a CFRP riser prototype with sufficient tensile strength and designing the carbon fiber/seal structure for the auxiliary lines.

testing 2/5 scale prototype

TAT Recommendation 0217-13: “Drill the Well on Paper” Exercise before Resumption of NanTroSEIZE C0002 Riser Drilling

• A few months before actual operations, CDEX should conduct a three-day DWOP exercise to test the drilling plans, risk assessments, decisions trees, and contingency plans.

• Participants should include: onshore planning team, co-chief scientists, Chikyu offshore leadership team, reps of service providers, a professional facilitator, and TAT rep D. Castillo.

• DWOP output should include detailed operational sequence, check lists, contingency operational responses for unanticipated geological issues, and recommendations to ensure that operations or changes to operations are carried out without problem

• After the DWOP, CDEX should consider contracting a drilling simulator so the actual Chikyu drillers can conduct a “drilling the well on simulator” to train for proper responses to unanticipated events.

on Access to Genetic Resource and the Fair andequitable Sharing of Benefits Arising from their Utilization (ABS)

JapanParty Status: Party to the Nagoya ProtocolEntered into force on: 20 Aug 2017Acceptance on: 22 May 2017Signatory: Signed on 11 May 2011

new!

The Nagoya Protocol

What’s difficult to comprehend?

Not only commercial use, scientific research also creates Benefits.

ABS law varies from country to country.

Different contractual issue with the Marine Science Research clearance(MSR clearance ≠ ABS permission)

Not like MSR clearance, ABS continually affects post cruise research.

Subseafloor sediments are genetic resources with rich diversities and great potentials.

Prior Informed Consent (PIC)

Japanese focal point has answered that NO PIC is required when providing

Japanese genetic resources to outside Japan.

CDEX, JAMSTEC will seek PIC from other countries when required.

Material Transfer Agreement (MTA)

JAMSTEC has prepared MTA for providing genetic resources from Japanese EEZ.

MTA was implemented for Exp. 370 samples for the first time, and also was used for

sample requests to KCC.

Implementations of ABS measure for IODP expeditions of Chikyu

The Nagoya Protocol has been ratified and entered into force in Japan in 2017.

KCC will contract with ABS consultant to supervise our implementation.

Curators are encouraged to refer to the Access and Benefit-Sharing Clearing-

House website (www.cbd.int/abs/) for updated information on emerging

legislation and regulations that apply to the use of core samples.

2. IODP Expedition 380 NanTroSEIZE(C6)

Evaluated that the well is planned based on the experience and procedure followed so far gained during the offset wells drilled in the past, and no major risk would be encountered for implementation

The key for this project is whether the cement is placed around the sensors of the observatory string as per the plan

Since this operation is riser-less operation, no information of fluid return availableSuccessful cementing operation can, however, be accomplished by monitoring the amount of cement pumped in conjunction with the cement plug as well as by monitoring pressure indication carefully

3. Safety Review on Casing DesignIODP NanTroSEIZE (C2) Exp.358

Agreed to the casing program CDEX designed (3 sets of liners, including 2 sets of Expandable-No back up)

Focused on improvement of collapse pressure: Current Plan

1. Swellable packer to be utilized instead of cement setting2. 2. 9-5/8” CSG tie-back needs to be conducted

3. 3. 9-3/8” Liner Hanger to be changed to in the 13-3/8” CSG

Suggested the utilization of VSP in conjunction with geomechanics-study is worth considered for the last open hole section

Points of what we want to know …


Efficiently operate and share both facilities and equipment

→TAT ConsensusTAT recommends the success of the recently completed Expedition 380 that installed the Long-Term Borehole Monitoring System at Site C0006. Despite issues with releasing the Drill Ahead Tool and the LTBMS, the LTBMS testing system, and the failure of the bi-center bit for drilling out cement, the expedition finished 17 days ahead of schedule.


Improve and maintain research environment to researchers onboard


Contribute as a hub for international human resource exchanges


Contribute to the promotion of advanced science and technology

→TAT ConsensusCDEX Technological Developments. TAT was very pleased about the progress in ongoing CDEX technology developments.TAT was impressed that several of these new technologies (LTBMS, CFRP, TDCS…) have been or will be implemented and may have applications in industry, and applauds the cooperation with the JOIDES Resolution Science Operator in the upcoming Expedition 376.
