Fram Centre Ocean Acidification flagship projects:

  • OAstate: Establishing the Current status of ocean acidification in the Norwegian Arctic
  • SICCA: The role of Sea Ice processes on CO 2 exchange and Calcium Carbonate saturation levels
The projects focus on the studies of the carbonate system in Arctic sea ice and water, ocean acidification, and biogeochemical processes driving sea-ice-air CO 2 exchange in the Arctic. We investigate the effect of sea-ice formation, and effect of glacier and sea-ice melt on the surface water carbonate chemistry. Field work are performed at all seasons in Svalbard fjords, north of Svalbard and in the Fram Strait, mainly using field logistics in Ny-Ålesund, Longyearbyen and onboard R/V Lance.

Interesser og spesialfelt

My research interests are mainly on the polar ocean carbonate system, CO 2 fluxes and biogeochemical processes in sea ice and seawater in Arctic and Antarctica. Focus is on the effect of increased CO 2 in the oceans, so-called ocean acidification, and the related processes for the understanding of seasonal and inter-annual variability. Main studies are on the effect of ice formation and ice melt from sea ice and glacier on surface water CO 2 and calcium carbonate saturation state, which is a measure on chemical stability of calcium carbonate. Processes within the sea ice and the exchange at air-ice-water interface are part of my research. Experience from field work and research expeditions to the Arctic and Antarctic since 1995.
