Jan 29 - Mar 18, 2019: RVIB Nathaniel B. Palmer, Pine Island BayScott Braddock and Meghan Spoth at the University of Maine spent six weeks aboard the icebreaker Nathaniel B. Palmer visiting ice-free islands in Pine Island Bay to collect data on sea-level change during the past several thousand years. 
Nov 2019 - Jan 2020: Mt. Murphy. Greg BalcoBrent GoehringSeth Campbell, and a team of field mountaineers and drillers  spent several weeks at Kay Peak, the westernmost part of the volcanic Mt. Murphy massif that adjoins lower Thwaites Glacier. Geological data from the north ridge of Kay Peak (shown at left) show that the currently-ice-free part of the ridge was exposed by ice sheet thinning approximately 5000-8000 years ago. This field group drilled through the ice covering the subglacial extension of the ridge to obtain similar data from the ice-covered part of the ridge and find out if and when the ice sheet was thinner in the past. 
Nov 2019 - Jan 2020: Hudson Mountains. Geologist Joanne Johnson and ice-penetrating radar specialist John Woodward spent several weeks in the Hudson Mountains, a group of volcanic peaks on the west side of Pine Island Glacier, collecting rock samples and radar data needed to choose a second drill site for the 2020-21 field season.  
Nov. 2020 - Jan 2021: Hudson Mountains. A drilling team will revisit the Hudson Mountains to collect subglacial bedrock samples.
