| Summary: | In the 2016-2017 austral summer, the University of Texas Institute for Geophysics (UTIG) and the Korean Polar Research Institute (KOPRI) collaborated to perform a helicopter- based radar and laser altimeter survey on the Lower David Lakes Catchment. This survey ties in with (and fills some of the gaps in) an ICECAP survey of the Drygalski Ice Tongue and the David Glacier grounding zone from 2011 and 2012 [Blankenship et al., 2017] in order to provide a 5 km resolution survey extending from the grounding line past the first two active subglacial lakes identified by Smith et al. [2009]. While this is far from the first aerogeo- physical survey of an active lake system, it is one of the most extensive, and provides higher resolution boundary conditions and basal characteristics that will enable process studies of these enigmatic features. ... |
