Argo Norway Kjell Arne Mork and Einar Svendsen Institute of Marine Research and Bjerknes Centre for Climate Research

Argo Norway The Institute of Marine Research (IMR) is involved in the international ARGO programme with contribution of Argo floats, ship time for deployment and user of the data ARGO Norway focuses on both research topics and marine climate monitoring of the Nordic Seas Data quality control is done by IFREMER

Institute of Marine Research has in total deployed 11 Argo floats that drift at 1500/1200 m depth June 2002 August 2003 April 2006 (includes oxygen and fluores.) The parking depth at 1500 m was chosen due to the topography and the low stratification in the deep water Atlantic water Arctic water Coastal water

All positions Positions of all Argo floats in the Nordic Seas, updated January Red dots are IMR floats. In total there are 3150 CTD- stations.

Cyclonic deep circulation D : Deployed : Last pos. June 2002 – November 2005 August 2003 – June 2006 Two floats:

Circulation at 1500 m depth from the Argo floats Bottom depth contour interval: 500 m : speed less than 10 cm/s : speed larger than 10 cm/s 1000

Monitoring Temperature anomalies (relative to WOA), averaged between 50 og 200 m depth, during October -December 2006

Biological activities April-December 2006 Floats include CTD, oxygen, fluoressence and turbidity sensors
