Nearly 60 scientists and support staff are on their way to Thwaites Glacier in Antarctica as part of the ambitious international effort to understand the glacier and surrounding ocean system to determine its future contributions to global sea-level rise. This season represents the fourth of five planned field seasons for the research.
Meghana's research focuses on uncovering the underlying physical processes governing ice flow and fracture, spanning scales from the micro-scale ice physics to macro-scale ice sheet behavior. Much of her work investigates the processes activated by rapid ice deformation, which typically take place in shear margins, from a modeling perspective. With the TIME project, she is assisting in the gathering of field measurements of the processes that she hopes to model, and the data from TIME will be invaluable in informing these parameterizations and a mathematical picture of ice deformation.
Emma Pearce is a postdoctoral researcher at the University of Strasbourg. She uses seismology (active and passive) to look at the structure of ice and is part of the 2022-23 TIME field team, helping with seismology.
Mark is a PhD student at the Scott Polar Research Institute, University of Cambridge. His research uses full-Stokes flow models to better understand the dynamic effects of subglacial topography, hydrologic drain networks, and ice fracture.
