vEGU2021: Session CR1.3 The Greenland IS over the last 3 Ma: constraints from archives and model comparison
we are glad to announce the following session CR1.3 at virtual EGU 2021. It welcomes any research about the long term history of the Greenland Ice Sheet (« long term » being here the past 3 million years).
The abstract submission deadline is 13 January 2021, 13:00 CET:
The Greenland Ice Sheet extents over the last 3 million years: constraints from archives and model comparison
Since the volume of the Greenland Ice Sheet (GrIS) represents more than 7 m of sea level equivalent, it is important to improve our knowledge of its stability over million years timescale, particularly during similar to and warmer than present periods. In particular, the extents and response time of the GrIS during the Early Pleistocene and during the warmest interglacials of the Late Pleistocene (e.g. MIS 11) are still poorly documented and understood. This session welcomes studies presenting advances on the long term record of GrIS extensions, during the last 3 million years. Results from any type of archives (marine sediments, ice, basal ice or substratum) involving multidisciplinary methods and proxies are particularly encouraged: sedimentological and glaciological descriptions, paleoecological reconstructions, mineralogical and geochemical analysis, geochronological constraints. Comparisons with modeling studies are also strongly encouraged.
