SUSPENDED MATTER CONCENTRATION ALONGSIDE THE NORTHERN COASTLINE OF KALININGRAD REGION (SOUTH-EASTERN PART OF THE BALTIC SEA)
South-Eastern part of the Baltic Sea undergoes strong man-caused impact due to high level of shore usage. Suspended matter is an important carrying agent for pollutants. The Kaliningrad region has both the abrasion shore (Sambian peninsula) and the massive accumulative body (Curonian Spit), which is World Heritage site. The interannual and seasonal distribution of suspended matter concentration along the northern shore of Kaliningrad region against the hydrological conditions were studied. The research was made on five-year (2011-2015) monthly (April - October) data-array, consisting of surface and bottom water samplings. Two types of interannual and seasonal distribution of suspended matter concentration (SMC) revealed: Sambian type is defined by vertical gradient of SMC with descending of concentration from surface to bottom, while Curonian type – by horizontal gradient of latter.
