What
US-SCAR is hosting a meeting for US scientists who are conducting research in, from or about Antarctica and the Southern Ocean. Scientists interested in getting involved in Antarctic research through US programs are also welcome and encouraged to attend. This conference is open to all US scientists and anyone interested in US Antarctic research. There is no registration fee.
The meeting will provide opportunities for US Antarctic scientists to get together and present their work, and for early career researchers and others new to Antarctic science to learn about SCAR and the various resources available to US scientists for Antarctic-related research. There will be a mix of Lightning Talks, panels and social activities for the US Antarctic Community to meet and interact.
The meeting and associated events will be on Zoom. The schedule (see below) is set for two hours each day (one hour science and one hour panel) with additional time added for socializing. The panels will have brief presentations by panelists, and most of the time will be devoted to questions and discussion.
Registration
The Zoom link for the meeting is provided with registration. https://usfca.zoom.us/meeting/register/tZEpdO2hqTIjH9aFTNATDn_Zl8XS-tRnidQz

*5-minute Lightning Talks with questions at end of session, number of concurrent sessions will be determined by number of abstracts submitted
Lightning Talks
Anyone formally affiliated with a US institution, organization, agency, etc. can submit an abstract for a talk. The abstract submission deadline is June 21, 2020. Abstract should be <1300 characters.
To maximize interactions, provide ample time for questions and to keep the online format effective, talks will be pre-recorded and limited to five minutes, what is referred to as a “Lightning Talk”. There is much information about Lightning Talks available on the Internet, here are a few sources with explanations and tips: SSI, ST, BL.
Please see the instructions for details specific to the US Antarctic Science Meeting. You will only be allowed one abstract as a lead author, there is no limit as a co-author.
For presenters: Since a five-minute talk means that you may have to skip over many details, you have the option to provide a poster or a longer pre-recorded presentation (maximum 15 minutes) that will be posted online for public viewing. Anyone interested in the details of your work will have the opportunity to learn more. Optional supplemental materials can be submitted online.
