Icefin and hydrographic profile data, and noble gas water samples from the Kamb Ice Stream subglacial channel cavity

The data sets archived here come from a subglacial channel beneath the Kamb Ice Stream at 152.29°W, 82.47°S. They consist of one dive with the Icefin underwater vehicle, vertical profiles from a conductivity-temperature-data (CTD) profiler, lowered acoustic altimeter, and acoustic doppler current profiler, and seven discrete water samples that were analyzed for noble gas concentrations and helium isotope ratios. There are additional noble gas concentrations and helium isotope ratios from water samples collected at the Whillans Ice Stream at the WISSARD site (163.67°W, 84.33°S) and the Ross Ice Shelf front. These data have the associated hydrographic information enclosed in each file.
