Zoom webinar #3 2024: on Monday 17 June, 12:00 – 13:30 UTC

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 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:

• 1. Jakob Dörr – Post doc at University of Bergen, Norway
     • Present and future influence of ocean heat transport on winter Arctic sea-ice variability
  2. 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
  3. 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

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

Zoom webinar #2 2024: on Monday 22 April, 13:00 – 14:30 UTC

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 some of the striking changes in the Arctic Ocean and their impact on the characteristics and ecosystems of the Arctic Ocean. It will be moderated by Øyvind Paasche, the chair of the SAS scientific steering committee. There will be three solicited talks with room for questions and discussions:

• 1. Alexandra Jahn – Associate Professor at the University of Colorado Boulder, USA
     • Projections of an ice-free Arctic Ocean
  2. Suzanne Tank – Associate Professor at the University of Alberta, Canada
     • The Arctic Great Rivers Observatory: Long Term Trends in River Chemistry Diagnose Multi-Faceted Northern Change
  3. Clare Gaffey – PhD candidate at Clark University, USA
     • Characteristics of Light, Heat, and Chlorophyll Pigments in the Pacific Arctic During the 2022 U.S. Synoptic Arctic Survey Cruise

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.
