Taken from sections of the report:
This report describes aspects of the fieldwork completed for the Australian Antarctic Division (AAD) mapping program during the Austral summer 2003-04. The mapping program was undertaken in harmony and collaboration with the Geoscience Australia geodesy program in Antarctica, between 16th November 2003 and 2nd February 2004. Surveyors from both ... organisations, including Henk Brolsma (Mapping Officer, AAD) and A. Corvino (author), teamed up to successfully complete a wide range of goals. The principal objective of the Geoscience Australia geodesy program was to install three remotely located continuous GPS stations in the southern Prince Charles Mountains (PCM) and Grove Mountains (Corvino, 2004). That project is not discussed further in this report. The main objectives of the AAD mapping program were to survey ground control points (GCPs) for geo-referencing new satellite imagery and to complete terrestrial survey work in the vicinity of Davis station. The following tasks were completed:
- Downloading of the tide gauges at the Larsemann Hills and Davis station;
- Transfer of local sea level at the Davis tide gauge to an absolute height datum using GPS;
- Establishing a new survey mark at Beaver Lake and connecting it to the existing survey marks;
- Conducting GPS surveys of selected ground features for geo-referencing satellite imagery at Beaver Lake, Marine Plain, the Grove Mountains and Wilson Bluff;
- Establishing new survey marks at Marine Plain in the Vestfold Hills;
- Computing the alignment of the UWOSCR instrument in the Space and Atmospheric Sciences (SAS) building at Davis station;
- Surveying lake levels in the Vestfold Hills; and
- Various local surveying tasks at Davis station.
A few aspects of the fieldwork that were completed exclusively by surveyor Brolsma are not included in this report. In particular the report is concerned with the tasks that were undertaken using GPS survey methods, which includes the tide gauge surveys, image control surveys and the fieldwork at Beaver Lake and Marine Plain. Photographs that document the fieldwork and support the text are included throughout. GPS processing reports and photographs showing the locations of the GCPs are provided as Appendices.
