This dataset resulted from a GPS survey of contaminants at the abandoned Wilkes station, Windmill Islands, Antarctica in January, February 1999. The survey was carried out by Nadia Babicka of Macquarie University in collaboration with Dr Ian Snape of the Australian Antarctic Division. Assistance was provided by David Smith of the Australian Antarctic Data Centre in converting Nadia's GPS data to GIS format and creating an interactive map to display the data.

The zip file available for download from this metadata record includes: 1 A readme file outlining its contents; 2 An ArcMap 9.2 document displaying Nadia's data against a background of topographic data; 3 A folder of photos taken by Nadia. These photos are linked in the ArcMap document to the point, line and polygon features collected by Nadia.

The topographic data displayed in the ArcMap document is from the Australian Antarctic Data Centre's GIS database. The AADC also has an orthophoto of Clark Peninsula which could be used as background in the ArcMap document. Submit a request at https://data.aad.gov.au/aadc/requests/ if you would like a copy of the orthophoto.

A more recent survey was carried out by Kirstie Fryirs of Macquarie University in 2010. Refer to the metadata record with ID 'ASAC_1163_WilkesGIS_2010'.

Polygon features representing the official zoning boundaries. Original zoning file acquired by the High Country Council of Governments from the Town Planner, Rawls Howard, Town of North Wilkesboro in 2008. Updated by High Country Council of Governments on a quarterly basis from re-zoning information from the Town once approved by the Board of Commissioners. Last update: January 2017.

In 2010 we undertook sampling of soil and waters around Wilkes station and the main tip site. We repeated the work of Snape et al. 1999 and took a more dense set of samples across the area to determine the extent and types of contamination. These data are complementary to the 1999 GIS dataset (see the metadata record with ID - ASAC_1163_WilkesGis_1999).

Description: Additional spatial data were collected and added to the existing AAD Wilkes GIS database (Nadia Babicka map). Locations of sediment, water, potentially hydrocarbon contaminated sediment, potentially hydrocarbon contaminated water and background samples were collected by Macquarie University and AAD staff, in January 2010, including hyperlinked sample photos; locations of Wilkes station buildings with numbers from Snape et al (1998)

The dataset comprises of a digital polygon/point coverage of lakes and ponds identified from documented field observations compiled by Dr Ian D Goodwin from his own field notes as well as topographic and surface lake features identified and interpreted on aerial photographs taken by AUSLIG (now Geoscience Australia) in the 1993-94 field season. Each lake/pond is represented as a polygon with a central point label which is linked to a separate digital database (ie attribute tables) containing additional information. Sediment samples collected predominantly along the shoreline of these lakes represent a chronology of glacial events/influences on these lakes. Sediment samples taken as a profiled sequence or core can be dated using radiocarbon dating to provide a chronological picture and age occurance of deglaciation and glaciation cycles within the Windmill Islands.

This dataset includes maps produced from the Australian Antarctic Data Centre GIS for use in environmental management of the 'old' Casey station tip site and the abandoned Wilkes station site: a map of the Windmill Islands showing the locations of Casey and Wilkes, contour maps of Casey and Wilkes and a map showing the water flow directions at Casey. The maps were used for locating contaminated areas and identifying the processes involved in contamination spread. Also included in the dataset is the GIS topographic and derived data used to create the maps.

It comprises a digital map showing the locations of Windmill Islands lichenometric observations and a linked digital database containing the maximum thallus size recorded at each location. It includes observations of lichens growing on nunataks for which the time of deglaciation is known and observations of lichens growing on supraglacial moraine ridges for which the time of formation is not known. This dataset thus provides the basis for a relative chronology of moraine development based on the assumption that the growth of the lichen thallus has been constant since the time of deglaciation. These data were compiled by Dr Ian D Goodwin from his own field notes and from the records of other workers. See the linked document at the URL below for further information.

It comprises a digital map showing the locations of some abandoned penguin colonies (represented by points) and a linked digital database containing additional information. The importance of these sites derives from the fact that a chronology of penguin occupation can be established by radiocarbon dating and this in turn provides a minimum age for deglaciation of the Windmill Islands. These data were compiled by Dr Ian D Goodwin from his own field notes and from the records of other workers. See the linked document at the URL below for further information.

This dataset contains GIS spatial layers of the medium and heavy disturbance footprint surrounding Casey Research Station at the years 2002, 2008, 2015 and 2018. The footprint mapping used a consistent methodology for digitisation for the years 2002, 2015, and 2018, whereas the year 2008 included ground-truther field measurements. Some variation in the footprint is due to snow cover hiding areas of disturbance. The sources and date of the data used is as follows: • 2018 Casey Heavy Disturbance – digitised by S. Brooks from Worldview-3 imagery, captured 27/1/2018. • 2018 Casey Medium Disturbance – digitised by S. Brooks from Worldview-3 imagery, captured 27/1/2018. • 2015 Casey Heavy Disturbance – digitised by S. Brooks from AAS 5024 UAV-imagery. • 2015 Casey Medium Disturbance – digitised by S.

This dataset is one of a number of datasets containing geomorphological data relating to the Windmill Islands, Wilkes Land, Antarctica. The dataset comprises of a digital point coverage of glacial sediments, collected and identified from documented field observations compiled by Dr Ian D Goodwin from his own field notes as well as topographic and surface features identified and interpreted on aerial photographs taken by AUSLIG (now Geoscience Australia) in the 1993-94 field season. Each glacial sediment sample is represented as a point which is linked to a separate digital database (ie attribute tables) containing additional information. Sediment samples collected on glacial moraine ridges and along raised beach ridges and shorelines represent a chronology of glacial events/influences on the landscape. Sediment samples taken as a profiled sequence or core can be dated using radiocarbon dating to provide a chronological picture and age occurance of deglaciation and glaciation cycles within the Windmill Islands.

The dataset comprises of a digital single point coverage of a Jokulhlaup event near Casey Station (ie outburst of water from beneath a cold ice-cap terminus on Law Dome). This event was observed and documented by Dr Ian D Goodwin. The Jokulhlaup is represented as a point which is linked to a separate digital database (ie attribute tables) containing additional information. From the results of oxygen-isotope and solute analysis, the water was found to have originated as basal melt water. It contained a high total solute load with a dominant enrichment in alkalis, indicating that it has been squeezed through subglacial sediments for an extensive time period. This event represents one of the first known recordings in Antarctica and provides further insight into determining the subglacial hydrological regime beneath the Law Dome ice cap.
