SAS webinar: The Arctic Ocean’s carbon cycle

Zoom webinar on Monday 18 November, 13:00 – 14:30 (UTC)

Poster of SAS webinar #5

The Synoptic Arctic Survey (SAS) aims to map the present states and ongoing changes of the Arctic Ocean ecosystem, carbon cycle and associated hydrography. It does so by enhancing ongoing ocean monitoring with ship-based measurements.

This webinar showcases recent updates on carbon exchange between the different pools in the carbon cycle of the Arctic Ocean. Marine carbon originates from river run-off (terrestrial) or air-sea fluxes (atmospheric) and is exported to the deep through large-scale currents where it feeds benthic organisms, if there is sufficient light and other nutrients. There will be three solicited talks with room for questions and discussions:

  1. Caroline Gjelstrup – Postdoc. at DTU Aqua, Denmark
    • Tracing the origins and fate of freshwater and organic carbon in the lower limb of the AMOC
  2. Sayaka Yasunaka – Professor at Tohoku University, Japan
    • Arctic Ocean CO2 uptake
  3. Karl Attard – Associate professor at University of Southern Denmark, Denmark
    • Seafloor primary production in a changing Arctic Ocean: Status and trends

The webinar will take place in Zoom. If you would like to join the webinar, please register to receive the meeting link:

SAS webinar: Dynamic processes in the Arctic Ocean

Zoom webinar #4 2024 on Monday 23 September, 12:00 – 13:30 UTC

Announcement of webinar #4: Dynamic processes in the Arctic Ocean

The Synoptic Arctic Survey (SAS) aims to map the present states and ongoing changes of the Arctic Ocean ecosystem, carbon cycle and associated hydrography. It does so by enhancing ongoing ocean monitoring with ship-based measurements.

This webinar showcases how ocean dynamics influences different processes of the Arctic Ocean. The circulation of water masses redistributes nutrients that provide the sustenance for the lower trophic levels of food webs in the marine ecosystem. It will be moderated by Øyvind Paasche, the chair of the SAS scientific steering committee, who will also give a brief introduction to the SAS initiative. There will be three solicited talks with room for questions and discussions:

    1. Peigen Lin – Associate professor at Shanghai Jiao Tong University, China
      • Recent state transition of the Beaufort Gyre
    2. Andreas Rogge – Post doc. at Alfred Wegner Institute, Germany
      • Dense shelf water propagation and subduction drives lateral injection of particulate organic carbon into the deep Nansen Basin
    3. Johan Wikner -Professor at Umeå University, Sweden
      • Contribution from prokaryotes to the Central Arctic Ocean carbon cycling
