Adam is a geophysicist, interested in using geophysical methods (usually seismic and GPR) to understand the physical properties of the shallow subsurface. He particularly enjoys stealing approaches from the resources industries, and applying them in glaciological, environmental and archaeological settings. In TIME, he is a member of the Active Seismic crew.

Michelle Maclennan (she/her) is a PhD student in the Department of Atmospheric and Oceanic Sciences at the University of Colorado Boulder. Her research focuses on ice-atmosphere interactions, in particular the impact of snowfall and extreme precipitation events on the surface mass balance of Thwaites Glacier. Michelle is combining recent observations from automatic weather stations on Thwaites ice shelf with reanalysis datasets to examine the spatial and temporal variability of snowfall and its connection to large-scale atmospheric circulation as part of the TARSAN project.
A multibeam-bathymetric compilation for the southern Amundsen Sea shelf, 1999-2019
Multibeam-bathymetry data provides a high resolution 3D rendering of the seafloor that, when collected offshore large marine-terminating glaciers, inform us about potential warm water pathways towards their grounding lines, as well as about the terrain that ice has moved over and shaped in the past. Now available is a new compilation of multibeam-bathymetric data for the inner Amundsen Sea continental shelf beyond Thwaites and Pine Island glaciers. The primary dataset was collected in 2019 by the THOR team during the first cruise of the International Thwaites Glacier Collaboration (ITGC).
Processed line aerogravity data over the Thwaites Glacier region (2018/19 season)
Aerogravity data has an important role to play in constraining sub-surface geology under grounded ice and bathymetry beneath floating ice shelves. This dataset contains aerogravity collected by the British Antarctic Survey as part of the International Thwaites Glacier Collaboration (ITGC). Data were collected using both a traditional stabilised platform approach, and a more modern strapdown gravity system. Flights were flown at a constant altitude ~450 m above the ice surface where surface topography was flat. Gravity data is also recovered along draped sections by the strapdown system.
