[CRYOLIST] Reminder: Call for abstracts on Southern Ocean research at EGU2022

Dear colleagues,

We would like to draw your attention to two upcoming Southern Ocean sessions at the EGU General Assembly 2022 in Vienna, 3–8 April 2022:

OS1.10 The Southern Ocean in a changing climate: open-ocean physical and biogeochemical processes

Abstract submission: https://meetingorganizer.copernicus.org/EGU22/session/42190 

Solicited speaker: Jean-Baptiste Sallée

and

OS1.11 Under cover: The Southern Ocean's connection to sea ice and ice shelves

Abstract submission: https://meetingorganizer.copernicus.org/EGU22/session/42181

(session details and links for abstract submission provided below)

The sessions will be run in a hybrid EGU vPICO format, allowing for both in-person and virtual participation (https://egu22.eu/about/provisional_meeting_format.html). We will make sure that sufficient time for discussion is allocated to our sessions.

Please consider to submit a contribution to either session by 12 January 2022 at 13:00 CET.

We hope to see many of you in Vienna and make this an exciting and inspiring session! Please feel free to circulate this announcement to colleagues who may be interested. 

Kind regards, 

Lavinia, Camille, Alex, Dan, and Chris

and 

Torge, Xylar, Alice, and Ralph 

========== SESSION DETAILS ==========

OS1.10 The Southern Ocean in a changing climate: open-ocean physical and biogeochemical processes

The Southern Ocean around the latitudes of the Antarctic Circumpolar Current is vital to our understanding of the climate system. It is a key region for vertical and lateral exchanges of heat, carbon, and nutrients, with significant past and potential future global climate implications. The role of the Southern Ocean as a dominant player in heat and carbon exchanges in present and future climate conditions remains uncertain. Indeed, the lack of observations of this system and its inherent sensitivity to small-scale physical processes, not fully represented in current Earth system models, result in large climate projection uncertainties. To address these knowledge gaps, the Southern Ocean has been the subject of recent observational, theoretical, and numerical modelling investigations. These efforts are providing deeper insight into the three-dimensional patterns of Southern Ocean change on sub-annual, multi-decadal and millennial timescales. In this session, we will discuss the current state of knowledge and novel findings concerning the role of the Southern Ocean in past, present, and future climates. These include (but are not limited to) small-scale physics and mixing, water mass transformation, gyre-scale processes, nutrient and carbon cycling, ocean productivity, climate-carbon feedbacks, and ocean-ice-atmosphere interactions. We will also discuss how changes in Southern Ocean heat and carbon transport affect lower latitudes and global climate more generally.

Conveners: Lavinia Patara, Camille Akhoudas, Alexander Haumann, Dan Jones, Chris Turney

OS1.11 Under cover: The Southern Ocean's connection to sea ice and ice shelves

The interaction between the ocean and the cryosphere in the Southern Ocean has become a major focus in climate research. Antarctic climate change has captured public attention, which has spawned a number of research questions, such as: Is Antarctic sea ice becoming more vulnerable in a changing climate? Where and when will melting of ice shelves by warm ocean waters yield a tipping point in Antarctic climate? What role do ice-related processes play in nutrient upwelling on the continental shelf and in triggering carbon export to deep waters? Recent advances in observational technology, data coverage, and modeling provide scientists with a better understanding of the mechanisms involving ice-ocean interactions in the far South. Processes on the Antarctic continental shelf have been identified as missing links between the cryosphere, the global atmosphere and the deep open ocean that need to be captured in large-scale and global model simulations.

This session calls for studies on physical and biogeochemical interactions between ice shelves, sea ice and the ocean. The ice-covered Southern Ocean and its role in the greater Antarctic climate system are of major interest. This includes work on all scales, from local to basin-scale to circumpolar. Studies based on in-situ observations and remote sensing as well as regional to global models are welcome. We particularly invite cross-disciplinary topics involving physical and biological oceanography, glaciology or biogeochemistry.
