Chirikov Gulf, and through the Bering Strait near Alaskan 

 shores enters the Chukchi Sea. The second part is found in the 

 central region of the Chukchi Sea. 



Thus, there is a mixing of three faunistic groups in the 

 Chukchi Sea (east, west neritic. and north Bering Sea). In the 

 Chirikov Gulf (Bering Sea), a mi.ving of two faunistic groups 

 occurs (east and west neritic). and in the Gulf of Anadyr, three 

 (west neritic, north, and south Bering Sea). 



The conclusions obtained from the similarity of neuston 

 fauna in the areas investigated according to Preston's methods 

 (Preston, 1962) were confirmed in detail by biogeographic 

 analysis based on quantitative as well as qualitative data. 



The mosaic distribution of Bering Sea faunistic groups in 

 the neuston layer of the Chukchi Sea confirm the coinplex 

 hydrodynamics of near surface waters and their connection 

 with the Bering Sea.
