Bed, surface elevation and ice thickness measurements derived from radar data acquired during the Thwaites Glacier airborne survey (2019/2020)
As part of the International Thwaites Glacier Collaboration (ITGC) 4432 km of new radar depth sounding data was acquired over the Thwaites Glacier catchment by the British Antarctic Survey. Data was collected using the PASIN polametric radar system, fitted on the BAS aerogeophysical equipped survey aircraft VP-FBL. The survey operated from Lower Thwaites Glacier camp, and focused on collecting data in regions of ice >1.5 km thick between 70 and 180 km from the grounding line.
Chris Kratt is the Laboratory Coordinator for the Center for Transformative Environmental Monitoring Programs (CTEMPs) at the University of Nevada, Reno. He provides technical and logistical support to Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) research projects. He has a Masters degree in geology and co-instructs an undergraduate Applied Geophysics class. Mr. Kratt also has private sector experience conducting a variety of geophysical surveys.

Scott Tyler is a Foundation Professor in the Department of Geological Sciences and Engineering at the University of Nevada, Reno and director of the CTEMPs Community User Facility focusing on the development and application of fiber-optic based sensing for environmental temperature and strain. His research spans the atmospheric boundary layer, through the soil and has included deep groundwater circulation. He is currently serving as past president of the AGU’s Hydrology Section.
With training in mechanical engineering and hydrogeology, his recent work focuses on the measurement of the dynamics and thermal evolution of Antarctic ice shelves and the ocean waters below. As part of the TARSAN project, he has helped developed the fiber-optic moorings of the AMIGOS weather stations and is developing a distributed acoustic monitoring system for both ice shelf and the ocean below for testing at Thwaites in 2021/2022.
Dave joined British Antarctic Survey in 2001 and is currently the Operations Programme Manager. He is responsible for the planning and delivery of the global annual programme to Antarctica, including that for the International Thwaites Glacier Collaboration, translating scientific requirements for logistics support in to operational delivery.
Writer Douglas Fox accompanied ITGC researchers into the field in 2019/2020, where he witnessed TARSAN scientists Erin Pettit, Ted Scambos, MELT scientist Britney Schmidt, and others drill into the Thwaites Glacier ice shelf to learn about the shelf's properties and its thickness. What surprised the team the most was the vast amount of life under the shelf.
