Coen Hofstede is a member of Alfred Wegener Institute's (AWI) field glaciology group with more than two decades of experience in scientific and industrial applications of reflection seismics. His focus lies on small-scale active seismic surveys on Greenland Outlet Glaciers and Antarctica. He is in charge of AWI's seismic equipment. During the GHOST traverses, he will operate the vibroseismic source and seismic streamer to image the basal structure of Thwaites Glacier. That equipment is tailor made for such an operation and combines a seismic vibrator with a snowstreamer, towed by a tracked vehicle from shot location to shot location.This enables them to record around 20 km of profiles per day. He will perform subsequent data processing and interpretation, determining basal properties (acoustic impedance) and subglacial geologic structure.

Olaf Eisen is head of the field glaciology group at the Alfred Wegener Institute and a professor for glaciology at the University of Bremen. With two decades of experience of applying geophysical techniques on glaciers and ice sheets, he heads a team in charge of operating the Alfred Wegener Institute's vibroseismic source and seismic streamer during the GHOST traverses. These processes aim to continuously map the subglacial structure in the survey area of Thwaites Glacier. The team's equipment is tailor-made for such an operation, and combines a seismic vibrator with a snowstreamer, towed by a tracked vehicle from shot location to shot location. This enables the team to record around 20 kilometers of profiles per day. They will perform subsequent data analysis and interpretation to determine basal properties and subglacial geologic structure.

Eric Rignot is a glaciologist and remote sensing scientist at UC Irvine and at NASA's Jet Propulsion Laboratory. He is interested in ice sheet mass balance and ice-ocean interaction in Greenland and Antarctica. As part of MELT, he will provide to the team the latest information on the grounding line position of Thwaites from satellite interferometry and will generate remote sensing estimates of ice shelf melt to be compared with data to be collected in the field.

Rob Arthern is a glacier modeller at BAS. He will be responsible for modelling the evolution of Thwaites Glacier, specifically in response to the melt rates at the grounding line determined both by direct observations, and by the grounding zone parameterization to be developed within the MELT project. He is also a scientist on the GHOST team.

Keith Makinson is a physical oceanographer at BAS, and is responsible for developing hot-water drills used by BAS. Within MELT, he will be responsible for the hot-water drilled access holes and ensuring instrumentation can be safely deployed through them. He will also be active in the interpretation of the ocean datasets from the sub-ice shelf environment, particularly with respect to tidal activity.

Paul Holland is an ice-ocean modeller in the Shelf Seas group at the British Antarctic Survey. He will be responsible for coordinating the different modelling components of the project. In particular, he will assist with the installation of the grounding zone parameterization into MITgcm.

Professor Paul Brennan is a co-investigator for MELT. He is responsible for developing novel instruments to be deployed in a borehole upstream of Thwaites Glacier grounding line that will be used to measure the vertical shear in the ice column. These results will be used to help validate, amongst others, the WAVI model of ice sheet evolution.

Professor Matt Piggott is a co-investigator of MELT. He is responsible for applying leading-edge techniques in numerical modelling to the ocean environment in the grounding zone of Thwaites Glacier. The aim is to create a parameterization, validated by in situ observations, of the rate at which the base of the ice shelf in the grounding zone is melted by the ocean.

Fernando Rodriguez is the RF and microwave systems lead at the Center for Remote Sensing of Ice Sheets (CReSIS). He is a Co-Investigator on the MELT project. He will lead the CReSIS hardware team in developing the Accumulation Radar for the MELT project.
