1977-78 Season
Engineers: David Reed, Eberhand G. Schirmacher, Robin Schumtzler,
and Harry Zohn, Jr.
Intersected peak positions determined by terrestrial surveys
employing Wild T-2 theodolite for angular measurements and Electro-tapes
for distance measurements from positions developed by geoceiver (Doppler)
observations.
Elevations based on sea level using the NASA Goddard Earth
Model (GEM) 10B.
Located in Ellsworth Land at the N central edge of the Sweeney Mountains,
unmonumented station.
Survey mark - 2" x 2" hub set in snow surface.
Surveyed on 11 January 1978.
Horizontal Datum - The positions are based on WGS 66 datum. The adjusted
network was fitted to the geoceiver stations by a least squares transformation
and the residuals were less than two meters.
Vertical Datum - Geodetic heights corrected to the geoid using NASA
GEM 10B. No direct connections to sea level were made.
