Sea ice is a challenging habitat for microorganisms. Most microbial cells live in narrow brine channels, where they face subzero temperatures, high salinity, oxidative stress and restricted access to oil compounds. Despite these harsh conditions, a number of bacterial species thrive there, capable of breaking down various petroleum compounds and using them for metabolic processes.

In July, the Norwegian research vessel Kronprins Haakon set out on a 50-day voyage as part of the Arctic Ocean 2050 research programme. After collecting samples at the North Pole, the expedition headed towards Canada and has now reached its westernmost point.
