SAS 2024 webinar 3 02

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. For more information, please visit our website:

This webinar showcases how the characteristic sea-ice in the Arctic Ocean is varying, and how changes in sea-ice cover affect both the global carbon cycle and Arctic marine ecosystems. It will be moderated by Are Olsen, the co-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:

Jakob Dörr - Post doc at University of Bergen, Norway

Present and future influence of ocean heat transport on winter Arctic sea-ice variability

Zhangxian Ouyang - Researcher at University of Delaware, USA

Sea-ice loss amplifies decadal surface CO2 increase and enhances ocean acidification in the western Arctic Ocean 

Yuri Fukai - Post doc at JAMSTEC, Japan

Impact of sea-ice dynamics on the spatial distribution of diatoms in sediments of the Pacific Arctic Region
