GHOST is an ice- and modeling-based project that will examine the bed and interior of Thwaites Glacier. The rheology and topography of the bed affect how quickly Thwaites retreats and contributes to sea-level rise: it could rapidly collapse, or retreat might slow or pause on a subglacial ridge (GHOST Ridge) 70 kilometers inland of the current grounding line. This study will also investigate whether the region of fast-flowing ice could expand into currently slow-flowing regions.
Sridhar Anandakrishnan is a professor in the Department of Geosciences at Penn State University. His research interests include reflection seismology, glaciology, and geophysics.
Anandakrishnan is a lead Principal Investigator on the GHOST project. He will travel to Antarctic to use seismic and radar methods on the ice to investigate and quantify the sediment, hydrology, and bedrock underlying Thwaites Glacier.
Anandakrishnan is also a co-investigator on the MELT project.
Andy Smith is head of the Ice Sheet Stability Programme at the British Antarctic Survey. His main research interests are in ice sheets and glaciers, and their role in the Earth system. He is particularly interested in fast glacier flow and subglacial conditions, as well as ice mass balance and ice sheet history.

Andy retired from BAS in March 2023 and Alex Brisbourne has taken on the PI role for the UK side of GHOST.
