Takket være at havet tar opp mye CO2 fra atmosfæren forsinkes den globale oppvarmingen. På den annen side leder opptaket av CO2 til havforsuring, som kan ha negative konsekvenser for marine organismer. Arktiske strøk er spesielt utsatt for havforsuring. Det er viktig å overvåke denne utviklingen, men Arktis er et utfordrende miljø å gjøre målinger i. I prosjektet ‘Iskantseilas’ vil vi skaffe data fra ishavet ved å bruke to ubemannede «mini-seilbåter», som kalles seilbøyer.

Sentinel 1A SAR Fram Strait. 30. June 07:12.: Sea ice in the Fram Strait is changing. Here is the sea ice distrubutions as of 30. June morning. KV Svalbard has deployed the Sail buoy near mooring U2 and its postion is shown, follow its voyage. Courtesy: Mohamed Babiker, NERSC.

The recovery of the UNDER-ICE moorings is pending on favourable sea ice conditions in the Fram Strait. The Nansen Center is monitoring the sea ice conditions daily in order to support the KV Svalbard cruise during the next 3 weeks.

Sentinel-1A images as of 29 June including the UNDER-ICE mooring locations to be recovered.Here is the latest images from Sentinel-1A including the locations of the moorings to be recovered.
