Opis:
The main 137Cs accumulation zone in the study area was found to be located at depths below the 50-metre isobath, i.e. below the layer of hydrodynamic activity. In coastal waters not influenced by the fresh water discharge from the Curonian Lagoon, 137Cs occurs mostly in soluble form. The particulate 137Cs activity concentration in the marine area affected by Curonian Lagoon water can make up 10% of the total 137Cs activity concentration. The circulation model was developed to assess the distribution of artificial radionuclides in Lithuanian territorial waters. The model was validated on the basis of data acquired during the measurement campaign in the Lithuanian part of the Baltic Sea and the Curonian Lagoon in the years 1999–2001. The model enables the 137Cs activity concentration to be simulated as a passive admixture (error within c. 15%).

Opis:
In May 2000 the hydrodynamic model developed at the Federal Maritime and Hydrographic Agency in Hamburg. Germany 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 137 Cs activity concentration was observed. However, 137 Cs 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.
