Abstract:Recent rapid thinning of West Antarctic ice shelves are believed to be caused by intrusions of warm deep water that induce basal melting and seaward meltwater export. Dotson Ice Shelf has a high basal melt rate due to southward ocean heat transport in the Dotson-Getz Trough. We deployed three bottom-moored instrument arrays along the ice shelf calving front, obtaining continuous records of temperature, salinity, and current velocity throughout 2014 and 2015. Southward deep water velocities were highest along t… Show more
