Research interests:

As a researcher, I study the biogeochemistry of polar oceans, with a particular interest in primary productivity and more broadly about the organic and inorganic carbon cycle. I have a geographically wide interest of the Arctic and Southern Ocean, from frontal jets and eddies, the high-nutrients low-chlorophyll regions, the sea ice covered areas, to the more coastal domain, including polynyas, and sea ice.

2018-now – Leader of the Southern Ocean Observing System (SOOS) Regional Working Group: Weddell Sea – Droning Maud Land

2018-now – Norway National Representative for the Southern Ocean Observing System (SOOS)

2018-now – SSC Member for the SCAR working group BEPSII: biogeochemical exchanges processes at the Sea Ice Interfaces

Current projects:

  • Biological Oceanography in the Southern Ocean: Droning Maud Land cruise on-board the Norwegian Icebreaker Kronprins Haakon in March-April 2019.
  • SANOCEAN project (NFR): Southern Ocean phytoplankton community characteristics, primary production, CO2 flux and the effects of climate change. Cooperation project between Norway and South Africa.

PhD thesis title: “Combined effects of UVB radiations and climate change on the marine microbial community west of the Antarctic Peninsula. Potential impact on the carbon cycle.”

Defense: March 30th 2011, Rimouski, Canada
