We are now accepting manuscript submissions to the SAS special collection called

2020-2022 Synoptic Arctic Survey: Unveiling the Status and Oceanic Trends

Here, we invite studies that use SAS data from multiple and single cruises to provide new insight on hydrographic, biogeochemical and ecosystem state processes and trends in the Arctic Ocean. It brings together assessments of the interconnected system and climate change in the Arctic Ocean and their far-reaching impacts, as a joint issue of three AGU journals:

  1.   Journal of Geophysical Research: Oceans
  2. Journal of Geophysical Research: Biogeosciences
  3. Global Biogeochemical Cycles

Please see the Call for Papers for more information and submission guidelines!

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:
