SCAR’s Open Science Conferences have been a focal point for the Antarctic research community since 2004. SCAR 2020 Online presented many of the science highlights originally planned for the 9th Open Science Conference in Hobart, cancelled due to the COVID-19 pandemic.

Report on the Organization of SCAR 2020 Online, 2020

Report on SCAR 2020 Online.

The SCAR 2020 Open Science Conference and Business Meetings were due to be held in Hobart, Tasmania, Australia from 31 July to 11 August. Following the cancellation due to cases of COVID-19 increasing worldwide, many of the highlights of the SCAR Open Science Conference were moved online. The result was SCAR 2020 Online (www.scar2020.org), held on the originally scheduled dates of 3-7 August 2020.

SCAR 2020 Parallel Session 25: Sea ice in the atmosphere-ice-ocean-biosphere system – How, where and why is it changing, and what are the effects?

Monday 27th July 2020: 06:00-08:00 and 11:00-13:00 (UTC)

Convenors: Petra Heil, Klaus Meiners, Rob Massom, and Pat Wongpan

While there is strong focus on rapid change occurring in Arctic sea ice, relatively little is known about the complex sea-ice environment around Antarctica (comprising both pack and fast ice), how and why it is changing and varying, and the wide-ranging physical, biological and chemical effects of such change/variability. Improved understanding of the southern coupled sea ice-ocean-atmosphere-biosphere system is required to truly explain the marked and baffling recent reversal in overall sea-ice extent – from a slight positive trend to successive record maxima peaking in 2014, followed by a rapid decline. While sea-ice extent and concentration are monitored reasonably accurately from space, much remains to be learned about the processes driving annual advance and retreat; the role of snow; sea-ice interaction with the ice sheet; sea ice as a habitat; sea-ice biogeochemical processes; and teleconnections with lower latitudes (including sea-ice relationships with southern hemisphere weather and climate).

SCAR 2020 Parallel Session 5: Antarctic Sea ice Variability and Change

Tuesday 28th July 2020: 19:00–23:00 (UTC)

Convenors: Marilyn Raphael, Ariaan Purich, Will Hobbs, Andreas Klocker

Antarctic sea ice is undergoing rapid and prolonged changes. These changes are complex in their spatial distribution, their seasonality, and even in their timescale – a long term positive trend since the late 1970s has been followed by an unprecedented rapid decline in Spring 2016. Sea ice sits at the interface between the atmosphere and the ocean and changes in sea ice are the result of the complex interaction of any of these three components – ice, ocean, and atmosphere. These changes have global implications; Antarctic sea ice formation, export and melt are crucial for ocean ventilation through the formation of both Antarctic Bottom Water and Antarctic Intermediate Water, and potentially affect the inflow of warm Circumpolar Deep Water beneath ice shelves, promoting the retreat of the grounded portion of the ice sheet, and consequently sea level rise. In spite of the challenges associated with observing and modelling the Antarctic coastal and sea ice zones, recent observational programs and focused model development efforts are now rapidly advancing our understanding of these processes.
