The Norwegian SI-ARCTIC program involves review of historical data and literature, field observations, numerical modelling, and analytical analyses. The cruises in the waters west and north of Svalbard in 2014 and 2015 provided information that I have been working with the Norwegians. Two additional cruises in 2016 and 2017 have been completed. The project forms the basis for the initiation of the development of an ecosystem based management strategy for the Arctic and aims to design a long-term monitoring program of the waters under Norwegian jurisdiction in the Arctic Ocean. Two papers describing the bioacoustical work have been published in 2017 and a third manuscript has been submitted for publication.
