The Institute of Marine Research has analyzed 182 Our Ocean commitments from the past five years. Overall, the commitments have mainly generated attention and funding. The direct impact on sustainable fisheries and management is less obvious.      

Researchers used to enter their survey data into cumbersome spreadsheets. These days they have StoX – a free, open source program, developed at the Institute of Marine Research (IMR) that has now been documented in an international research journal.

Today the UN’s Intergovernmental Panel on Climate Change (IPCC) is launching its special report on the oceans and cryosphere. Geir Ottersen, a scientist at the Institute of Marine Research (IMR) and one of the main authors of the report, is concerned about the changes taking place in the Arctic.

The Arctic cod, the Arctic cousin of the Atlantic cod, is a key species in the northern Barents Sea. The whole ecosystem may therefore be destabilised by the spawning grounds of the Arctic cod shrinking as a result of declining sea ice cover.
