Modeling and data perspectives on reconstructing Late Pleistocene ice sheets Pippa L
The aim of the “Joint model-data workshop for the Late Pleistocene evolution of the Greenland and Antarctic ice sheets” was to bring together scientists from the disciplines of field- and model-based ice-sheet reconstruction to identify outstanding issues in each field, and determine how the different communities could work together towards resolving them
Reviews of offshore information highlighted that many landforms relating to past ice extents are undated and sediment cores are often only acquired from trough regions, where the ice-sheet history may be very different to inter-trough regions
Summary
Modeling and data perspectives on reconstructing Late Pleistocene ice sheets Pippa L. The aim of the “Joint model-data workshop for the Late Pleistocene evolution of the Greenland and Antarctic ice sheets” was to bring together scientists from the disciplines of field- and model-based ice-sheet reconstruction to identify outstanding issues in each field, and determine how the different communities could work together towards resolving them. In terrestrial studies of past ice extent (e.g. Fig. 1) it was highlighted that dating continues to be an issue due to a lack of dateable material, the presence of recycled carbon, and the difficulty of interpreting cosmogenic isotope data due to inheritance from multiple glacial cycles.
