Geomorphological measurements and lithological classifications of 90 erratic cobbles from the Hudson Mountains, West Antarctica

This dataset contains geomorphological data (measurements of size, shape, long axis orientation and weathering characteristics) on 90 erratic cobbles collected from the Hudson Mountains in West Antarctica. These were collected during three field campaigns, as follows: 1) 75 erratic cobbles collected by Joanne S Johnson during a British Antarctic Survey-supported geological field campaign undertaken in November-December 2019, as part of the International Thwaites Glacier Collaboration (funded by NERC and NSF). 2) 13 cobbles collected by James A Smith (British Antarctic Survey) in February and March 2010 during RV Polarstern cruise ANT XXVI/3, and 3) a further two cobbles collected in March 2006 by Johnson during RV Polarstern cruise ANT XXIII/4. These cobbles were all collected for surface exposure dating. Funding: NERC grant: NE/S006710/1
