Geological Survey of Finland (GTK) is the national geological organisation under the Ministry of Employment and the Economy. GTK is a European center of excellence in assessment, research and sustainable use of Earth resources. GTK has approximately 600 employees.

GTK is nationally responsible for seafloor geological mapping in the Finnish territorial waters of the Baltic Sea. The main focus of Marine Geology and Global Change research programme of GTK is in gaining deeper understanding of long-term environmental changes in the Baltic Sea and its present-day sedimentation processes and geodiversity. This information will provide a basis for improved management, implementation of policy strategies in the Baltic Sea environmental issues, and for adaptation to the future climate change.

Within the FINMARI consortium, GTK is responsible for seabed geology. GTK is running the Geomari research vessel equipped with modern seabed survey and sampling facilities, providing information on seabed structure, composition and the sedimentation dynamics at seabed.
