Glacier Stake Locations

As part of the Long Term Ecological Research (LTER) project
in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been
undertaken to monitor mass balance and meltwater flow from the Taylor Valley
glaciers. This data set contains global positioning system (GPS) measurements of
stakes on glaciers. The measurements include both low-quality estimates (+/-
100m) from hand-held GPS units and high precision measurements (+/- 2 cm) using
Trimble (4000 SSE) geodetic receivers. The purpose of these measurements was to
obtain rough stake locations for use in relocating stakes in the future and
precise stake locations for use in calculating stake displacement. The
measurements are made relative to the WGS84 ellipsoid.
