AFI 07/02_07 Subglacial Lake Ellsworth - GRAVITY data, Antarctica, 2007/08
Listed in NASA Earthdata CMR
Gravity data acquired in the region of Subglacial Lake Ellsworth.
Description
Instrument Lacoste and Romberg land gravity meter. Drift control primarily contained within the local area.
Single, one-way tie to international gravity base station network (Rothera) Single survey line ~30 km long. Station spacing 2 km, except for 240 m spacing over the lake. Position, elevation, ice- and water-thickness data exist for each station.
