INVESTIGATION OF THE RELATION BETWEEN THE DISSOLVED 137CS ACTIVITY AND THE SIMULATED SALINITY IN THE LITHUANIAN COASTAL WATERS
Journal Title: Biuletyn Instytutu Morskiego - Year 2001, Vol 28, Issue 2
Abstract
In May 2000 the hydrodynamic model developed at the Federal Maritime and Hydrographic Agency in Hamburg. Gemzany was adopted to the Lithuanian part of the Baltic Sea. I nm grid is chosen. Comparison of measurements (1999.05.15) with the real time simulations of the particular period showed that in general, in the modelled area. the simulated salinity was higher than measured with most differences in the coastal zone. Average salinity distributions and the distribution of salinity standard deviations were analysed. The coastal area of 15 nm from the seashore, especially to the north of the Klaipeda Strait, is distinguished by the highest variance of the salinity. The relation between the salinity and the dissolved 137Cs activity concentration was observed. However, 137Cs activity bursts 1.5-2 times higher at the coast than the average, cannot be explained and are more likely to be related to the uplifted particulate matter.
