ALTERNATE NAME/NUMBER -
75º 49' 54.777" S
067º 14' 51.114" W
1430.3 Meters
ORVILLE COAST
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 on the Orville Coast approximately 40 km SW
of Matthews Glacier, approximately 35 km SE of Mt. Leek, and approximately
26 km E of Spear Glacier, monumented station.
Survey mark - Standard USGS tablet set in drill hole, stamped "MARY
1977-1978".
Surveyed on 23 December 1977.
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.
