Due to Covid-19, the next face-to-face PALSEA workshop has been delayed until September 2021. In 2020, we are hosting a free, online PALSEA Express, details which can be found here.
Improving understanding of ice sheet and solid earth processes driving paleo sea level change
Workshop organizers: Jacqueline Austermann (PALSEA) and Alexander Simms (SERCE)
Scientific rationale This meeting will focus on developing a better understanding of the physical processes that drive ice sheet collapse and solid earth deformation. These processes are highly uncertain due to a lack of observational constraints, yet they are the dominant drivers for local sea level change. Overcoming this uncertainty requires drawing from observations and expertise from a variety of fields complementary to PALSEA and SERCE including rheology, hydrology, glaciology, and geodesy. In this meeting, we aim to bring empiricists and modelers from the sea level and ice sheet communities together in order to unify solid Earth deformation and ice sheet evolution across time and spatial scales. Pairing our improved understanding of physical processes with enhanced paleo datasets will allow us to narrow in on ice sheet contributions to past sea level rise.
The first day of the meeting will be dedicated to better understanding past sea level, solid Earth deformation, and the glacial isostatic adjustment process. The second day will be dedicated to presentations addressing cutting-edge constraints on paleo ice sheets including ice sheet modeling and ice margin constraints. During the third day of the meeting we will address data stewardship in the sea level modeling community in breakout groups. In particular we will (1) try to establish best practices for the documentation, distribution, and citation of numerical code, (2) review what benchmarking across different 1D and 3D GIA codes exist and / or should be done, and (3) understand how ice and sea level model output should be made available to the community (what format, what platform).
Abstract submission and registration Abstract submission will open in 2021.
Sponsors and ECR/DCR support This workshop is sponsored by PAGES, INQUA (to be confirmed), SCAR-SERCE and the Lenfest Junior Faculty Development Fund (Columbia University). Funds will be available for Early Career Researchers (ECR) and Developing Countries Researchers (DCR).
Additional meeting information: Venue: The meeting will take place at Lamont-Doherty Earth Observatory in New York. Lamont is affiliated with Columbia University and is located 35 minutes north of Manhattan on top of the Palisades Sill overlooking the Hudson river. Hotel: We recommend staying at the HNA Palisades Inn close to Lamont and will arrange group transportation. We have reserved a room block, rooms have to be booked individually and can be reserved until mid August. Alternatively participants can choose to stay in New York city and take the shuttle to Lamont. Registration fee: tbc Invited speakers: Harriet Lau (UC Berkeley), Kerry Callaghan (University of Minnesota), Surendra Adhikari (JPL), Violaine Coulon (Université libre de Bruxelles), Rene Gassmoeller (UC Davis) Meeting activities: We plan a half-day fieldtrip as well as an evening outreach event and conference dinner.
