Survey report 2000/01 summer season Authors - Gary Johnston / Paul Digney / AUSLIG

They included: - ARGN reference mark surveys at Mawson and Davis. - Orthometric height connections between the Mawson ARGN site (AUS064) and the Mawson TGBM (AUS258). - Orthometric height connections between the Davis ARGN site (AUS099) and the Davis TGBM (AUS186). - Connection by GPS to the Tide Gauge Benchmarks at Mawson, Davis and Larsemann Hills. - Strengthen the Australian Antarctic Geodetic Network with GPS observations where possible. - Establish a permanent Australian monument and connection to existing Chinese monuments in the Grove Mountains. - Connect to Russian and Chinese Geodetic control points in the Larsemann Hills vicinity for datum unification. - Derive ellipsoidal heights for lake benchmarks in the Vestfold Hills for the purpose of developing a geometric geoid model for that area.
