Spatial variability of location of the boundaries of the cold intermediate layer and its thickness in the Baltic Sea in spring 2006

On the basis of field measurement data obtained simultaneously in late April - early May 2006 in the expeditions of the Russian and the German research vessels in the northern and southern parts of the Baltic Proper, the south-north (along the major axis of the sea) variability of the location of the upper and the lower boundaries of the cold intermediate layer is considered. The highest variability of the boundaries from station to station is pointed out, as well as the lack of any clear south-north trend in their changes. This speaks in favor of the independence of the formation of CIL at any particular place - as opposed to the existence of a common sea-scale transport of cold intermediate waters from some common source.
