6. 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

7. Time series at NACLIM website Fluxes 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

8. 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?

9. 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”
