Orthophoto of the biopiles and nearby area at Casey, derived from aerial photographs taken with an Unmanned Aerial Vehicle (UAV), 10 February 2013 - KMZ file

The .kmz file was created using the XTools Pro extension (12.0.1745) in ArcGIS 10.3. It utilises background imagery from an orthophoto created by Dr Arko Lucieer of TerraLuma (http://www.terraluma.net/) and the University of Tasmania for the Terrestrial and Nearshore Ecosystems research group at the Australian Antarctic Division (TNE/AAD). See the metadata record 'UAV_Biopiles_SABspill_ortho_1cm_ITRF2000' with ID 'casey_biopiles_ortho2013'.

The .kmz file also includes two vector layers which show:
1) The location of the excavation conducted in 2010/11 and 2011/12 to remove hydrocarbon contaminated soil associated with the Casey Main Power House spill (July, 1999); and
2) The location of the Permeable Reactive Barrier (PRB) funnel and gate used to control and treat hydrocarbon impacted melt waters from within the contaminated zone.

The product is associated with Australian Antarctic Science Project 4036: Remediation of petroleum contaminants in the Antarctic and subantarctic, and was produced as a visual aid for the publication 'On site remediation of a fuel spill and soil reuse in Antarctica' http://www.sciencedirect.com/science/article/pii/S0048969716315303
