The Polish part of the Gulf of Gdansk including the Puck Bay and the Puck Lagoon (1520 square km). Detailed investigations were done in the area of 630 square km (3 sheets of map 1:50,000: Gdynia, Gdansk, Sobieszewo).

During 2005-2007, ca 1,500 km of multibeam echosounding profiles were carried out and ca 790 km of shallow seismic lines, 164 samples of surface bottom deposits (boxcorer) and 150 vibrocores were taken. Standard investigations in the laboratory are being made: analyses of grain size distributions, geochemical analyses, 14C, pollen and diatomological analyses. The results of cruises and laboratory work will be presented on digital maps. The results of cruises and laboratory work are also stored in a computer database (Fox-Pro). Only echograms and shallow seismic are recorded in the CODA acquisition system.
