E2-M3A

Latitude and Longitude: 41.836 N, 17.756 E

Depth: 1204.6m

Oceanographic Region: Adriatic Sea, Mediterranean

News:

The observatory is undergoing maintenance and will be re-deployed at the end of October 2010

Description of the Site:

A well-known area of dense water formation through open-sea convection. The center of the Southern Adriatic is an area where vertical mass transfer (upwelling, winter convection) has a rather prominent role in distributing physical and chemical water properties and controlling the primary production (transfer of nutrients in the euphotic zone). Upwelling is determined by the intensity of the cyclonic circulation that in turn depends on the climatic conditions over the area. The site is therefore appropriate for moored measurements since it is possible, under certain circumstances, to neglect contributions of lateral advection processes.
