Digital terrain and snow model for Aboa absolute gravity station in 2003/2004, 2005/2006, 2011/2012, and 2017
Listed in NASA Earthdata CMR
Digital terrain, snow and ice model for absolute gravity station at the Finnish Antarctic research station Aboa, Nordenskiold Base, Dronning Maud Land, (73deg 02min S, 13deg 24min W).
Description
The surface of snow is mapped along a large number of quasi-continuous profiles, using RTK-GPS in a sledge towed by snowmobile, and by staking out the terrain by foot. More than 35 km of profiles are measured during each measurement season at a sampling interval of 1 m.
It is planned to repeat exactly the same tracks during future expeditions for monitoring and studying snow accumulation and its effect to absolute gravity measurement. The studies include also a stake line with 29 measurement points for monitoring snow surface heights and glacier motion. In 2017 field season mobile (backpack carried and snow-mobile driven) laser scanning was added as a terrain modelling method.
