W1-M3A

Latitude and Longitude: 43.79N, 9.16E

Depth: 1300m

Oceanographic Region: Ligurian Sea (Western basin), Mediterranean

News: The surface buoy is sending all data in near real-time. The subsurface mooring was successfully recovered in June 2010 and will be redeployed in 2011. On 28th October 2010, the CNR-ISSIA team successfully deployed both the pCO2 (ProOceanus PSI-PRO) and Nitrate (Envirotech MicroLAB) sensors under the surface buoy (see enhancements listed below)

Description of the Site: One of the most dynamically active and productive areas within the whole Mediterranean (43 49 N 9 07 E). A permanent cyclonic circulation with seasonal and interannual variability triggered by the Tyrrhenian current dominates the area. During the winter, processes of dense water formation often occur. This site has also been monitored for several years in terms of surface atmospheric parameters.
