The data sets consist of static and kinematic GPS data collected on the mery Ice Shelf using Leica 399 receivers. Additional GPS data were collected at Beaver Lake, Hamm Peak, Moushino Is., New Year Nunataks, Jetty Peninsula, and Else Platform. Most data are provided in UNIX Z compressed RINEX (Receiver INdependent EXchange) format, as described in the IGS standards - see http://www.igs.org/products Some data are compressed using the RINEX Hatanaka compression scheme. The standard RINEX file naming convention is used, i.e., an eight digit file name as bbbbddds.yyt, where bbbb refers to a four digit station name, ddd refers to the day number of the year, s refers to a session number and yyt is the file extension number where yy refers to the year and t defines the file type (o for observation file and n for navigation file. d indicates an observation file compressed using the Hatanaka compression scheme). All files are compressed using the UNIX Z compression scheme, as shown by the extension .Z. For example, base0010.98o.Z, base0010.98n.Z, base0010.98d.Z.

Taken from sections of the report: Introduction 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.

Taken from sections of the report: In recent years, Geoscience Australia (GA) has increased its capability on the Antarctic continent with the installation of Continuous Global Positioning System (CGPS) sites in the Prince Charles Mountains and Grove Mountains. Over the course of the 2006/07 Antarctic summer, Alex Woods and Nick Brown from Geoscience Australia (GA) collaborated with Dan Zwartz of the Australian National University (ANU) to install new CGPS sites at the Bunger Hills and Richardson Lake and perform maintenance of the CGPS sites at the Grove Mountains, Wilson Bluff, Daltons Corner and Beaver Lake. The primary aim of the CGPS sites is to provide a reference frame for Antarctica, which is used to determine the long-term movement of the Antarctic plate. Data from Casey, Mawson and Davis is supplied to the International GPS Service (IGS) and in turn used in the derivation of the International Terrestrial Reference Frame (ITRF). The sites also open up opportunities for research into post-glacial rebound and plate tectonics. In many respects CGPS sites in Antarctica are still in their infancy. Since the mid 1990's Geoscience Australia and the Australian National University have been testing new technology and various methods to determine the most effective way of running a CGPS site in Antarctica. A more detailed review of Australia's involvement in Antarctic GPS work can be found in (Corvino, 2004) In addition, a reconnaissance survey was undertaken at Syowa Station to determine whether a local tie survey could be performed on the Syowa VLBI antenna in the future. Upgrades were made to the Davis and Mawson CGPS stations and geodetic survey tasks such as reference mark surveys, tide gauge benchmark levelling and GPS surveys were performed at both Davis and Mawson stations. In addition, work requested by Geoscience Australia's Nuclear Monitoring Project, the Australian Government Antarctic Division (AGAD) and the University of Tasmania (UTAS) were completed. The 2006/07 Geoscience Australia Antarctic expedition proved to be one of the most successful Antarctic seasons by geodetic surveyors from Geoscience Australia. All intended field locations were visited and all work tasks were completed.

Dr John Gibson from The University of Tasmania requested that Alex Woods and Nick Brown collect moss samples from any locations visited during the Antarctic summer field season. While working in the field only a few moss specimens were found. No moss or lichen specimens were observed at locations such as Wilson Bluff, Dalton Corner, Beaver Lake or the Grove Mountains. Moss samples were collected at Richardson Lake and Mawson Station and these samples were frozen after collection and returned to Australia. This work contributed towards AAS (ASAC) project 1159.
