The University of Gothenburg has deployed three underwater robots in the Baltic waters around the leaks on the Nord Stream gas pipelines. This is done to be able to follow how chemistry and life in the sea changes over time due to the large release of methane gas. In addition, research vessel Skagerak is set to deploy on a new expedition to the Baltic Sea to test run the large, unmanned vessel Ran.
