Ryan Ruddick and Alex Woods, Geoscience Australia surveyors, carried out some survey work for Geoscience Australia and the Australian Antarctic Division (AAD) during the 2008/09 summer.

At Davis and the Vestfold Hills the work included:
1 Installing an absolute gravity benchmark at Davis;
2 A survey mark traverse at Davis and the survey of new buildings;
3 A Davis tide gauge levelling survey;
4 A survey of the Old Wallow for John van den Hoff of the AAD;
5 Measuring relative height differences between lake bench marks and lake water level, for 23 lakes in the Vestfold Hills.

At the Larsemann Hills a GNSS campaign and high precision level survey was conducted across the eastern portion of Broknes. Precise orthometric height differences were observed between survey marks to be used together with the GNSS derived ellipsoidal heights of survey marks, obtained over the last decade, to develop a model of the geoid/ellipsoid separation in the area which encompasses Law-Racovita, Progress II and Zhongshan.

At Macquarie Island precise orthometric height differences were observed from the tide gauges in Garden Cove to the Macquarie Island ARGN station and its reference marks. The level run made direct connections to survey monuments observed in previous tide gauge benchmark level surveys conducted on the island. They also did a site survey of a proposed power house site.

Their work also took them to the Grove Mountains, Wilson Bluff and Dalton Corner.

Ryan and Alex provided documents describing most of the tasks listed above. A zip file containing these documents is available for download from a Related URL below.

1 The data that was the product of the survey mark traverse and the survey of new buildings at Davis and which is on the ITRF2000 at 2000 horizontal datum.

2 The final Davis buildings and stairways data from the survey at Davis after the data was converted from the ITRF2000 at 2000 horizontal datum on which it was collected to the WGS84 horizontal datum on which the Australian Antarctic Data Centre's GIS data for Davis is stored. See the Quality field for more details about the datum conversion.
The final buildings and stairways data is included with the Australian Antarctic Data Centre's other buildings and stairways data for Davis and has Dataset_id = 279 in the attribute table.
