A British Antarctic Survey team is completing final preparations to fly 10 flights, collecting 40 hours and over 9000 kilometers of air survey mapping flights to support the large Antarctic International Thwaites Glacier Collaboration (ITGC) project. ITGC researcher Dave Porter of Columbia University's Lamont-Doherty Earth Observatory is participating to run the iMAR gravimeter. When large, and heavily field-based projects like ITGC are planned, it is common for preliminary fieldwork to precede the larger project, to accomplish both caching supplies and collecting some backbone data. This fieldwork lays the groundwork for future fieldwork.
