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 cl...
