The objective of Oceanological and Hydrobiological Studies, an international journal published by the University of Gdańsk in cooperation with the Academic Publishing Company Walter DeGruyter, is to provide the most comprehensive and reliable source of information on the current knowledge in the fields of science related to both oceanology and hydrobiology. The main emphasis is on publishing high quality articles, easily available to scientists from all over the world. As an editorial team, we are convinced that Oceanological and Hydrobiological Studies will continue to grow as a journal meant for scientists and researchers who wish to keep abreast of the latest developments in these fields of science.
