1) have you ever been on a boat?  What type?  How long?  How often?

2) do you get seasick?

3) have you handled ropes before?  on a boat?  climbing?  other?

Activities:

1) class room session to learn about the mooring and plan the cruises,including - make cruise plans

- make recovery plan (how to get the mooring on the ship safely including recovery of anchor)

- make list of lab & deck equipment needed

- design CTD sampling

- personal preparations (clothing, transport, etc)

2) recovery cruise, including

- loading of ship and science equipment (1 day, 2-3 students)

- instruction in safe operations, rope handling, rope&winch commands, tag line, air-tugger, winch usage, etc

- CTD casts carried out by students under supervision (prep of equipment, data acquisition) (before and after recovery)

- mooring operations (recovery) executed by students under supervision

- cleaning of buoy and recovery of sensors from buoy

- transport of buoy back to SIO

3) Mechanical work - cleaning and disassembling of buoy in seaweed canyon, 2 full days but can rotate (2-4 students at one time)

4) Data analysis

- read-out of raw data from mooring sensors in lab

- application of calibrations

- analysis of data in groups of two

- design of student website for data display (to grow over the years) (to be seen)

5) Prepare for deployment

- help with mechanical preparation of the new mooring &

- help with sensor servicing: cleaning, inspect, re-battery, possible ship to manufacturer for calibration

- consider sensor sampling issues

- test and set-up new sensors to be deployed

- participate in full integration test

6) deployment cruise:

- transport and loading of ship and equipment

- pre-deployment and post-deployment CTD casts

- mooring operations (deployment) executed by students under supervision

Nominal mooring location 32° 55.6N, 117 ° 18.9W

Need now:

- Cruise plan (schedule)

- Inform ship sked and STS

- Packing lists (what do we need to prepare and take)

- Assign instruments (to read up, get manuals, etc)

- Assign people for packing, transporting, loading, setting up/securing

Cruise plan (Status: 2011-04-29):

Distance to steam 23nm, 3hrs each way with harbor transit

3hrs steam to site2hrs for pre-recovery CTD (or different spatial lags) plus ship met data collection1.5hrs +1 hrs until anchor on deck1hr for removing sensors from buoy hull (keep sensors wet, cool, and dark until calibration)2hrs to dump data1hr to verify data½hr program sensors for calibration1hr attach to CTD rosette1hr CTD cast3hrs steam back

Decision to make:Do we want to do pre-recovery CTD, accepting long cruise duration, or do we want to do this parallel to other activities later, thinning out our personnel, or do we want to cancel the pre-recovery CTD altogether?Decision 4/29: Yes, do pre-recovery CTD. Try to obtain a towed/underway CTD system; Uwe to investigate availability (R. Pinkel?).

Responsibilities for instruments (2 students each):

•Atmospheric (wind, temperature, pressure, humidity, precipitation) and buoy controller (Gordy & Tej)•Physical (ADCP, MicroCats, SeaCats) (Ruth & Roy)•Biogeochemical (oxygen, chl-a fluorescence, pH) (Christina & Uriel)

Duties:•Read sensor/instrument manuals and bring electronic copies•Make list of calibration reference required (CTD, added sensors, water samples)•Confirm prior to departure that calibration references are on board and ready to operate, incl. documentation•Confirm after recovery that instrument status is properly recorded on log sheets•Confirm after recovery that data is downloaded•Make backup copies of data•Back ashore, transfer data to main data server

Help with loading needed:

Thu., 2011-05-19: (Roy & Gordy)•Pack boxes, load gear onto truck•Meet in Seaweed Canyon (T-45) at 13:00•Duration 2h

Fri., 2011-05-20: (Tej & Uriel)•Drive gear to ship and load onto ship•Meet in lab (NH 116) at 09:30•Duration 3h

Mon., 2011-05-23: (Gordy & Christina & Ruth)•Unload ship and drive gear to SIO, unload truck•Meet in lab (NH 116) at 09:30•Duration 3h

During week 2011-05-23 – 2011-05-27:•Misc. gear refurbishment•TBD
