SAS webinar: Examples of results from SAS expeditions

Zoom webinar #1 2024: on Monday 4 March, 14:00 – 16:30 (UTC+1)

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.

This webinar showcases some of the results from the above mentioned SAS cruises. 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.

SAS March Webinar

 

 

March 16th – Large-Scale Arctic Insights, 14:00 – 15:30 UTC (15:00 – 16:30 CET)

The Arctic Ocean is brimming with change. In SAS, we’re trying to approach and understand the totality of change and how it potentially connects the different compartments of the ocean. In this new March seminar we are extremely happy to present a diverse set of excellent speakers who will share recent insights on large scale Arctic oceanography, biology, and biogeochemistry in the spirit of the SAS. All are welcome to join. 

Mary-Louise Timmermans (Yale University): Ocean heat and freshwater dynamics and change in the Canadian Basin

Bodil Bluhm (University of Tromsø): Bio-physical coupling on the pan-Artic continental slope

Jens Terhaar (University of Bern): Around one third of current Arctic Ocean primary production sustained by rivers and coastal erosion
