Thwaites MELT: Temperature, salinity and velocity time series from the grounding zone region of Thwaites Glacier Eastern ice shelf (2020)

Variability in temperature, salinity and velocity was observed approximately 1.5 m beneath the base of Thwaites Glacier in the grounding zone region of the Eastern Ice Shelf as part of the International Thwaites Glacier Collaboration MELT project. Using a borehole deployable turbulence instrument cluster, the average temperature, salinity and velocity was observed over a 15-minute period every 2 hours.

Funding was provided by NSFPLR-NERC: Melting at Thwaites grounding zone and its control on sea level (THWAITES-MELT) NE/S006761/1.
