Interesting finds ready for analysis

Cruise diary: On 16 September we set foot on land for the first time in two weeks. This marked the end of this year’s SI_ARCTIC survey. Nineteen scientists had surveyed the ecosystem “from physics to whale” in the area west and north of Svalbard. This cruise was the third in as many years, and the data will be used to analyse relationships in the ecosystem.
