The geochemical characteristics of the bottom sediment in the pockmark area of the eastern part of the Gulf of Finland
... time pockmark-like structures have been detected in the south-eastern part of the Gulf of Finland with the help of a side-scan sonar and a profile recorder. The analysis of the distribution of microcomponents in the bottom sediment indicates that the pockmark area is located in the geochemical barrier border zone where the reducing medium of the incoming mineralized solution meets the highly oxidizing sea water medium. The hydrodynamic and geochemical processes in the pockmark zone create focal areas ...
Geological conditions for submarine groundwater discharge in the South-Eastern Baltic
... process. The study of the geological prerequisites for submarine discharge became the goal of this work. Analysis of various factors that potentially contribute to submarine discharge (fault tectonics, seismic activity, rock permeability, paleo-incisions, pockmarks) made it possible to identify areas of the bottom that are promising for further research. In the coastal zone, this is an area of bedrock outcrops on the northern underwater slope of the Kaliningrad Peninsula, forming a Paleocene-Eocene aquifer....
