Central Irminger Sea (CIS)

Latitude and Longitude: 59.7N, -39.7W

Depth: 2800m

Oceanographic Region: Irminger Sea, North Atlantic

News: The CIS site was last serviced in July 2010. The next maintenance cruise will be summer 2011.

Parameters measured:

Full-depth mooring sending datasets in near real-time since 2002 (optode added in 2008). No atmospheric datasets.

NB. all data are in near real-time (except pCO2 since July 2010)

Enhancement/Modifications planned within EuroSITES:

Continuation: real-time and delayed-mode data on PCO2, Chlorophyll, nutrients and water column physics. Develop links with the US OOI station planned for this site.

Enhancement: Oxygen optode added in 2008

Maintenance cruises: Annual research cruise to the site
