The partnership of the Space Sciences Commission of the Polish Academy of Sciences with the Baltic Sea and Space Cluster has resulted in international projects. Knowledge transfer between universities and the space and maritime industries has developed at the national and international level. Representatives of such universities like the Naval Academy, the University of Gdańsk, the Gdańsk University of Technology, and the University of Administration and Business have actively participated in these activities. The contribution of the research workers of the Institute of Oceanology of the Polish Academy of Sciences is very large. They brought a strong potential of knowledge about the use of space in sea research to the activities of the Commission and the Cluster. The participation of business representatives, members of the Baltic Sea and Space Cluster is very important. Among them are: Pomeranian Special Economic Zone, Gdynia and Gdańsk Sea Port Authorities, Nauta Shipyard and Crist Shipyard, Hydromega and Cador Consulting, Marine Technology and Sea Data, Echogram and Sevenet. The representatives of the Port of Hamburg, Hutchison Ports and ICTSI contributed a lot of knowledge during conferences and B2B meetings.
