NEW DATE: SAS April Webinar

April 22nd – Arctic Science Snapshots: Early Career Scientists, 16:00-17:30 (CEST)

In this SAS-webinar, Early Career Scientists (ECS) will present snapshots of their research in the Arctic. Short and concise presentations covering ongoing or planned studies of changes in physical oceanography, marine ecosystems as well as carbon cycle and ocean acidification.

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



SAS January Webinar

The planning of the 2021 field season is well underway, and several important Synoptic Arctic Survey (SAS) cruises will take place.

On this occasion we would like to invite you to join the SAS January Webinar, where we will be learning about some of these cruises, and the finer details that goes into biological sampling programs. We will also learn the latest about drivers of Arctic ocean acidification.

There will be time for questions and discussions after each presentation.

Date, time and location:

January 28. 2021

14:00 – 15:30 UTC (15:00 – 16:30 CET)

Online, see details below

Meet our new coordinator, Anne Kari

Hello Anne Kari Øhman Meisingset!

  • What is your background? I have an MSc in chemical oceanography from the University of Bergen where I studied the increase in anthropogenic CO2 in the Nordic seas and Arctic Ocean. After finishing my degree last year, I participated in an ICOS Norway project, and I have been working on getting my thesis published.
  • What will you be doing in the SAS project? I will join the SAS team as a coordinator.
  • What fascinates you about the Arctic? There is so many fascinating things about the Arctic, but what intrigues me the most is all the unanswered questions and the ability to be a part of a community that might answer some of them. For example, how will climate change affect the Arctic region, and how will the physical, chemical, and biological processes respond to that change? When I worked on my thesis I never really knew what to expect from my results in the Arctic Ocean since there is not many findings to compare with, and it was always exciting to dive into different theories that could explain what I found.

The Synoptic Arctic Survey (SAS) – Informational Meeting during the AGU’s Fall meeting in San Francisco

December 11, 2019, 14:30 – 15:30
ARCUS Community Meeting Room Monterrey II

222 Mason St.
San Francisco, CA

The Synoptic Arctic Survey (SAS) is an ongoing international
program conducting a multi-nation, oceanographic field based
effort on a Pan Arctic Scale over two years (2020-2021) during a
single season (late summer).

With this the SAS seeks to achieve the baseline understanding of
the fundamental structure and function of the linked
carbon-ecosystem-physical systems that will permit detection of
ongoing and future changes in the Arctic Ocean.

The first cruises will take place in late summer 2020. Several
cruises will also take place in 2021. Join us for an informal
update on the status of the international efforts.

All are welcome.

Chair (SSC)) and Carin Ashjian (Int.’l SSC Member and Co-Chair, US SSC)
