Opis:: Studies on Baltic nodules have been undertaken since the1920s. In the 1970sand 1980s, the Polish Geological Institute - National Research Institute conducted researches on the bottom sediments of the Baltic Sea, which allowed identifying the regions of occurrence of Fe-Mn nodules in the southern part of the Baltic Sea (Mojski, 1989-1994). Nodules from the Polish Baltic Sea Zone are the least studied element of the marine environment. So far, there is a lack of information on environmental-geological conditions of formation and occurrence of nodules, their metal resources and deposit potential. The Fe-Mn nodules may be a valuable source of information on the contamination of the Baltic Sea water and bottom sediments. In cooperation between the Institute of Oceanography of the University ofGdañsk and the Polish Geological Institute-NRI, two research cruises were carried out in August and September 2020 on a 5 X 5 km testing ground in the Gotland-Gdańsk Threshold region. The seabed surface was profiled using multibeam echo sounders and a side-scan sonar. A hundred samples of Fe-Mn nodules, 25 samples of surface sediments associated with the nodules, and25 samples of clay rocks underlain by marine sediments were collected. The extensive documentary material will enable, for the first time, to estimate the nodule resources and determine the regularity of their occurrence.

Opis:: For the past 50 years, Poland has been actively involved in the research on marine mineral resources. Since 1987, research cruises and documentation of the polymetallic concretions (Fe-Mn) in the Clarion-Clipperton Zone on the Pacific seabed have been performed as part of the Interoceanmetal project. In 2016, the IOM presented a report to the ISA on the past research and new technologies for processing concretions, together with an economic analysis regarding the process of development of concretion deposits. In 2018, ISA granted Poland the right to search for polymetallic sulphides in the Atlantic Ocean. At the same time, a government project called PRoGEo was launched to encourage the reconnaissance search for marine minerals. This opens a new chapter in the history of Polish participation in the search for marine mineral deposits. Poland is an active participant in international organization, created based on the Convention on the Law of the Sea. Initially, Polish involvement was limited to legal matters, and then extended to geology of the sea and marine mineral deposits. A more active role of Poland in marine exploration during the last years requests to familiar Polish geologists with the current stage of knowledge about marine resources. The current state of knowledge of marine mineral deposits, though still requiring further research, is sufficient to plan their development in the near future. This paper argues that the deposits of polymetallic sulphides, Co-rich crust, gas hydrates and polymetallic concretions will likely be developed first.
