Hi everyone,

The next ATOC Colloquium will be held in a hybrid format on *Friday, March
1 from 11a–12p MT over Zoom and in SEEC S228*. This week's colloquium will
feature a seminar from *Dr. Alice DuVivier (NCAR/CGD)* entitled, "Projected
Changes in Antarctic Coastal Sea Ice and Ecosystems". The zoom login
information and an abstract for the colloquium are provided below. *Notably,
this colloquium coincides with an ATOC prospective graduate student visit
day, so please make every effort to attend if you can in order to meet the
amazing slate of students who may join ATOC in the Fall! *Please join us
for conversation beginning at 10:45am MT, and stay afterwards for a lunch

*Projected Changes in Antarctic Coastal Sea Ice and Ecosystems*
Alice DuVivier (NCAR/CGD)

The Southern Ocean is one of the fastest changing regions on the planet as
the globe warms. In polar regions, coastal polynyas – open water areas
along the coast bordered high regions with higher sea ice concentration –
are “hot spots” of high biological productivity. This talk will discuss how
the fully coupled Community Earth System Model (CESM) has been used to
assess projected changes in Antarctic sea ice and coastal polynyas. The
talk will present recent, extreme changes to Antarctic sea ice, present
model-satellite comparisons, and discuss strengths and weaknesses of the
CESM model for representing Antarctic sea ice, and in particular polynyas.
Additionally, we examine modeled primary and secondary production in
polynya regions and possible connections to known penguin colonies.
Ultimately, we are working to understand the ecological importance of
small-scale polynyas for the Antarctic ecosystem from phytoplankton to
penguins and to create a quantifiable metric that can be used to inform
Southern Ocean conservation, including the development of marine protected
areas.
