Meetings, Workshops, Seminars, and Colloquia

Most seminars and colloquia at NASA/GISS are presented during the academic year, September through May.

Formal seminar presentations by visiting scientists are normally held on Friday (11 a.m.) once or twice during the academic year.

Informal lunchtime seminars (usually presented by NASA/GISS, Columbia/EI, and/or Columbia/LDEO scientists) take place on Wednesdays (1 p.m.) about twice per month.

Since late 2019, GISS staff have organized a Tuesday morning (11 a.m.) series of Sea Level Rise seminars (YouTube) presented by scientists from numerous research institutions. This seminar occurs two or three times per month.

Following are upcoming seminars, workshops and other events of interest to GISS staff and to our research partners. Please note that due to security regulations, as described elsewhere on this page, presentations on the GISS premises are not open to the general public.

Events marked "Virtual Only" are presented on-line for remote attendance only. Please consult with the event host/contact for connection details.

Sea Level Rise Seminar
Speaker: Ella Gilbert (Reading Univ UK)
Title: Atmospheric influence on melt and hydrofracturing-induced collapse on ice shelves


This is an on-line, virtual presentation only. Please consult with event host Craig Rye for connection details.


Abstract:
Against a backdrop of ongoing climatic warming in recent decades, several ice shelves on the Antarctic Peninsula have collapsed via hydrofracture, including the Prince Gustav, Larsen A and Larsen B ice shelves. We know that the first-order cause of these types of collapses is melting at the surface, but the drivers of that surface melting remain largely unquantified. In this talk I will discuss modelling work that centres on the Larsen C ice shelf -- which neighbours the now-absent Larsen A and B ice shelves -- before zooming out to explore what might happen to ice shelves across the whole Antarctic continent with ongoing warming. Understanding the atmospheric processes that contribute to surface melting can provide valuable context for making predictions of the future fate of ice shelves, and of sea level rise.

GISS Lunch Seminar
Speaker: Lettie Roach (GISS/Columbia Univ.)
Title: Antarctic sea ice asymmetry


This is an on-line, virtual presentation only. Please consult with event host Clara Orbe for connection details.


Abstract:
The mean seasonal cycle of Antarctic sea ice extent is asymmetric, with the period of ice retreat being nearly two months shorter than the period of ice advance. This feature is largely consistent in observations from year to year, across different satellite products, and for both sea ice extent and sea ice area. The asymmetry is also broadly reproduced by comprehensive climate models across generations from CMIP3 to CMIP6, with limited impacts from internal variability. Using a range of idealized climate models of varying complexity, I show that the asymmetry has a simple physical explanation that is markedly different from those proposed in previous studies. I will end by discussing some implications for the seasonality of Arctic sea ice.

Security Note

Federal regulations require that visitors to NASA/GISS arrange in advance for a building pass. However, due to the COVID pandemic, visitors have not been admitted to the GISS premises since March 2020. When such admissions are again permitted, there may be restrictions based on the vaccination status and also the ID presented.


As of late September 2021, visitors to Goddard Space Flight Center facilities (including GISS) must fill out a COVID-19 attestation form at the proper badging office in order to gain access to our center. No further action is required if a visitor attests to being vaccinated. If, however, a visitor attests to being unvaccinated, not fully vaccinated, or chooses not to disclose their vaccination status, they will need to submit proof of a negative COVID-19 test taken within the previous 72 hours.

Due to implementation of the REAL ID Act (2005), a state driver's license or identification card has been required for admittance to the GISS premises, which is considered a federal facility. However, if you have a state-issued license or ID that is not considered REAL-ID compliant, we urge you to do so before one is required to enter a federal facility. Enforcement of this requirement was expected in October 2021, but apparently has been postponed to May 2023 due to the COVID epidemic.


Persons who are not U.S. citizens or U.S. permanent residents and who may be planning a visit to GISS require that special arrangements be made. Please co-ordinate with your GISS host on this at least three weeks before your visit.

All visitors can expect to have their bags searched upon entry to GISS. This may include having to answer questions about personal items, including any medication the visitor may be carrying.
