Title: Sea Level Changes Around Greenland: Paleo, Processes, and People


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


Abstract:
Nonperiodic sea level changes around Greenland are the combined response of solid Earth uplift, steric effects, and gravity field variations driven by changes in glaciers and ice sheets. Due to the adjacent ice sheet, sea level and shallow water changes around the coast of Greenland may be large, as shown by the Greenland GPS Network, which has documented uplift rates between 3 and 23 mm/year. This large variability in observed and projected sea level change across settlements around Greenland compels a closer investigation into the local modulators of global and regional changes. Our convergent research team from LDEO and the Greenland Institute for Natural Resources (GINR) is focusing on the integration of the natural, the social, and the built environment of four different Greenlandic communities proximal to the changing ice sheet. Here, we present a case study of Nuuk, the capital and location of the longest tide gauge record in Greenland. We leverage this historical tide gauge data and more recent GNET GNSS data against modeled sea level changes from a suite of modified Huy3 and ICE6G GIA models. By comparison with a variety of Earth viscosity models, we infer constraints on past sea level changes and Holocene ice margin evolution in Southwest Greenland.

With a view towards the future of coastal evolution around Greenland, we are partnering with local communities for siting and installation of new tide gauges in our four partner coastal communities, each representing a unique set of natural, built, and social environments. Starting in 2020, driven to improve the co-production of all aspects of the scientific method, LDEO and GINR hosted hybrid in-person/virtual meetings with community members and schools in two of our communities, Nuuk and Aasiaat. Meetings were focused on listening to concerns and observations of community members, resulting in discussions spanning from planning of sewage outflows, alterations of safe sea passages, and engaging the youth in STEM fields.

Security Note

Federal regulations require that visitors to NASA/GISS arrange in advance for a building pass. Persons attending a GISS seminar or colloquium should contact the event host at least two days in advance of the event for assistance. Please include your affiliation in your e-mail.

Due to implementation of the REAL ID Act (2005), a state driver's license or identification card is currently (as of spring 2020) 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, you are urged to obtain one before entrance regulations change, which is expected to occur Oct. 1, 2021.

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.
