NACLIM CT 2Monitoring of North Atlantic parameters

New Lead: Johannes Karstensen (GEOMAR) and Karin M. H. Larsen (HAV)

WP 2.1 Exchanges across the Greenland-Scotland RidgeLead: Karin M. H. Larsen (HAV)

WP 2.2 Transports in the subpolar North AtlanticLead: Johannes Karstensen (GEOMAR)

WP 2.3 Joint model – observational data comparisonLead: Detlef Quadfasel (UHAM)

& Bert Rudels (FMI)

We discussed:

• Deliverable & Milestones status– OK!

• Short Presentations:– for information on activities– To identify collaborative efforts

• Data and Data QC• CT2 Meeting – end of 2014 to precise the collaboration more

Data & Data quality control flags

• In relation to NACLIM external Reviewer comment

• For collaboration with other CTs:– Format of data? CF compatible? ASCII?

“data products” and customized different flags

Time series at NACLIM websiteFluxes• Faroe Bank Channel overflow transport Updated 25

March 2014• Hornbanki section Atlantic inflow volume and heat

fluxes• Labrador Sea western boundary current transport at

53° N• RAPID — transport of MOC components at 26.5° N• Wyville Thomson Ridge overflow transport Updated 14

March 2014• Faroe Shetland Channel volume, heat and salt fluxes of

Atlantic Water, and total fluxes Updated 30 March 2014• Denmark Strait overflow transport• Iceland-Faroes Atlantic inflow Updated 25 March 2014• Kogur Array freshwater flux New! 11 April 2014

Mooring data

• Angmagssalik array • Irminger Sea mooring Long-term Ocean Climate

Observations LOCO2 • Irminger Sea mooring Long-term Ocean Climate

Observations LOCO3 (upcoming)

Hydrography

• Hornbanki section hydrography • Irminger Sea hydrography• Nordic Seas hydrography• Denmark Strait hydrography• Central Labrador Sea temperature

time series• Properties of the Atlantic Water

Core in the Faroe Current Updated 25 March 2014

Entrainment

• Denmark Strait overflow plume

Data & Data quality control flags:data products

Example: moored current meter time series• Proposed QC Flag:

number of moorings used to determine transport time series (1, 2, 3…)• In addition: flag for “interpolated data” maybe with explanation or reference on how the

interpolation was done?

OSNAP / NACLIM Collaboration & Dissemination

• Meeting Dec. 2013 in Boston – coordination of mooring activities (location, cruises) in Irminger Sea: LOCO

(NIOZ), CIS (GEOMAR) with OOI node• Teleconferences & Meeting at OCEAN Science Feb. 2014

– Presentation of NACLIM (Gerard), Cruise coordination, array optimization • NACLIM member/steering Committee of OSNAP• Best practice in transatlantic collaboration (Workshop) Oct. 2014

– OSNAP/NACLIM/RAPID + national (VITALS; 53°N array) • Need to collect information about and pay attention to “shared events”
