Update on SAS session at ASSW2021

SAS has a session on ASSW2021. Submit abstracts through the ASSW21 website https://assw2021.pt/

The new deadline is Dec 10, 2020.

 

ASSW21 Theme: Observing the Arctic

Session ID: 17 – The Synoptic Arctic Survey (SAS) Activities

Abstract

The Central Arctic Ocean remains profoundly understudied, particularly carbon cycling, ecosystem alteration, and associated changes in atmosphere, ice and ocean physics that influence those biological and biogeochemical systems. The region is expected to continue to make marked changes over the next decades, driven by ongoing climate warming, yet our understanding of key process is limited for this area. The international Synoptic Arctic Survey (SAS) seeks to quantify the present states of the physical, biological, and biogeochemical systems of the Arctic Ocean. Multiple countries have both confirmed and pending cruises as part of the 2020/2021 SAS networked activities. Key goals of the SAS are to establish the present state of the Arctic system, to document temporal changes where possible through comparison with historical data, and to quantify linkages between the adjacent shelves, slopes, and deep basins, objectives that are shared with the broader Pan-Arctic effort of the composite SAS. The SAS consists of regional shelf-to-basin ship-based surveys in 2020 and 2021 to obtain a Pan-Arctic understanding of essential ocean variables (EOVs) on a quasi-synoptic, spatially distributed basis in which no single nation bears the full burden of collecting the requisite data. The multi-country field effort will provide a strong basis for educational opportunities for early career scientists. This SAS session will outline the benchmark and important legacy for SAS activities to future, quasi-decadal assessments of rapid and evolving Arctic Ocean system change. Updates on the 2020 SAS field program results and upcoming national plans for 2021 activities will be provided during the session.

Key-words

Central Arctic Ocean, Pan-Arctic, ecosystem, climate change

SAS November Webinar

CTD, R/V Mirai 2020, Western Arctic Ocean.

The Synoptic Arctic Survey (SAS) completed four cruises this fall in the Western Arctic Ocean, where the latest one with R/V Mirai just arrived back in Shimizu (Japan) from the Canada Basin.

On this occasion, we would like to invite you to join the SAS November Webinar where representatives from each cruise will report back from the expeditions. Much changed because of the pandemic, but most cruises still carried out their sampling program and collected physical, chemical, and biological measurements that will become part of SAS’s pan-arctic dataset.

In addition to the cruise reports, there will be an update on “ARCTIC CENTURY”, the Russian/Swiss/German contribution to SAS 2021 that will sample across the Kara Sea with the icebreaker Akademik Tryoshnikov. We will also see some highlights from the recent yearlong MOSAiC cruise.

There will be time for questions and discussion after the last talk.

Date, time, and location:

November 19, 2020
15:00 – 17:00 CET
Online, see details below.
