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:
Peigen Lin - Associate professor at Shanghai Jiao Tong University, China
Recent state transition of the Beaufort Gyre
Recent state transition of the Arctic Ocean’s Beaufort Gyre | Nature Geoscience
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
Carbon dioxide sink in the Arctic Ocean from cross-shelf transport of dense Barents Sea water | Nature Geoscience
Johan Wikner - Professor at Umeå University, Sweden
Contribution from prokaryotes to the Central Arctic Ocean carbon cycling
- preliminary data from the SAS Oden cruise in 2021
The webinar will take place in Zoom. If you would like to join the webinar, please register to receive the meeting link:

The Synoptic Arctic Survey (SAS) is a researcher-driven initiative that aims to enhance ongoing ocean monitoring with ship-based measurements, to establish the present states of the Arctic Ocean ecosystem, carbon cycle and associated hydrography. SAS has coordinated a multi-ship survey using an international fleet of icebreakers and research vessels, where more than 25 cruises from 11 different nations collected a set of parameters across the Arctic Ocean in 2020-2022. This comprehensive dataset will allow for unprecedented assessments and provide a unique baseline to track future climate change and its impacts.
