Average wind speed reaches a maximum in May-June (9m s.) and a minimum in November-December (6 m s.). About 85% of the time winds blow from northerly directions.

Primary production and distribution of phytopigments in the water column and sediments on the upwelduction was also measured and sedimentation of organic matter was estimated using moored sediment traps. On the basis of simultaneous hydrographic measurements, two water types could be distinguished. Upwelling water covered the southern shelf and the outer part of the northern shelf.
