Collaborative Research: Synthesis of Thwaites Glacier Dynamics: Diagnostic and Prognostic Sensitivity Studies of a West Antarctic Outlet System
Entry ID: parizek_0758274

[ Update this Record ]

Abstract: This NSF-ANT award supports a three-year study to isolate essential physical processes affecting Thwaites Glacier (TG) in the Amundsen Sea Embayment (ASE) of West Antarctica using a suite of existing numerical models in conjunction with existing and International Polar Year (IPY)-proposed data sets.

Purpose: Four different models will be utilized to explore the effects of embayment geometry, ice-shelf buttressing, basal-stress distribution, surface mass balance, surface climate, and inland dynamic perturbations on the present and future dynamics of TG. This particular collection of models is ideally suited for the broad nature of this investigation, as they incorporate efficient and complementary ... View entire text

Description: The "West Antarctic Links to Sea-level Estimation (WALSE)" workshop was sponsored by the UK Foreign and Commonwealth Office's Science & Innovation Network, the UK Department for Environment, Food and Rural Affairs (DEFRA) and by the Jackson School of Geosciences at the University of Texas. WALSE has been officially endorsed as an IPY activity. This site houses a consensus statement that resulted from the workshop. Ice sheet-outlet glacier-ocean-atmosphere interactions as well as the influence of stabilizing/de-stabilizing boundary conditions were highlighted and discussed at this meeting and relate to the work we performed for this award.

Description: The Thwaites outlet system has become a targeted study area for regional modelers participating in the Sea-level Response to Ice Sheet Evolution (SeaRISE) project. Information about this community-organized effort as well as data sets used in the modeling studies can be found through links at this URL. SeaRISE seeks to use existing models to provide insights into ice-sheet sensitivity and guidance to future model development through a suite of simulations with moderate-to-extreme forcing scenarios over the next 100-500 years.
