Aerial photography (35mm film) of penguin colonies was acquired over the Steinnes Group (Eric Woehler). The penguin colonies were traced, then digitised (John Cox), and saved as DXF-files. Using the ArcView extension 'Register and Transform' (Tom Velthuis), The DXF-files were brought into a GIS and transformed to the appropriate islands.

The dataset comprises Adelie penguin colony boundaries derived from oblique aerial photographs taken towards the end of the 2014/15 summer between Mawson and Taylor Glacier. The aerial photographs were geo-referenced to AAT coastline polygon data and the boundaries of Adelie penguin colonies were digitised.

An occupancy survey in January 2011 found a total of 14 islands/sites in Windmill group had populations of breeding Adelie penguins. The boundaries of breeding colonies at 11 of the 14 islands were subsequently mapped for abundance surveys. Four of the islands, Nelly Island, Hollin Island, Midgley Island and Beall Island were mapped from aerial photos taken in January 2011. Images were taken on the 2 January 2011 [Hollin, Midgley, Beall] and 23 January 2011[Nelly]. Mapping involved digitising polygons around sub-colonies from vertical aerial photographs. The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies.

Six colonies with breeding Adelie colonies were mapped this season on Kista Island. On Bechervaise Island subcolonies C and R were not mapped and so are missing from the final layer, but birds were present in these subcolonies. Subcolonies were mapped by circumnavigating the perimeter of sub-colonies on foot while carrying a Garmin GPS (Legend Cx) to log the track taken. The person walking the perimeter of the sub-colonies maintained a buffer distance of approximately 2.5m between themselves and the breeding birds along the sub-colony boundary. This buffer distance was reduced to approximately 2m in the final shapefiles.

Occupancy surveys in November 2009 and December 2010 (Southwell and Emmerson 2013) found a total of 2 Adelie penguin breeding sites in the Bolingen Island group between longitudes 75.333oE-75.912oE. The boundaries of breeding sub-colonies at 1 of these sites (Lichen Island, 73030) were subsequently mapped from vertical aerial photographs taken for abundance surveys on 20 November 2010 (for details of aerial photography see Southwell et al. 2013). The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies. The other breeding site (73156) was photographed obliquely from a helicopter using a hand-held camera on 6 December 2010. Colony boundaries for this site were drawn and digitised by eye.

An occupancy survey in January 2011 found a total of 14 islands/sites in Windmill group had populations of breeding Adelie penguins. The boundaries of breeding colonies at 11 of the 14 islands were subsequently mapped for abundance surveys. Seven islands were mapped on the ground with GPS: Whitney Point, Blakeney Point, Shirley Island, Odbert Island, Berkley Island, Cameron Island and O'Connor Island between 10 December 2012 to 9 January 2013 ). The buffer distance was reduced to 1-2 m in the shapefiles created from the ground maps. Ground mapping involved circumnavigating the perimeter of sub-colonies on foot while carrying a Garmin GPS (Legend Cx or Vista C) to log the track taken. The person walking around the sub-colonies maintained a buffer distance of 2-3 m between themselves and the penguins at the sub-colony boundary to minimise disturbance.

Seven colonies with breeding Adelie colonies were mapped this season in the Kista Island group between the 17th and 27th of November 2015. Subcolonies were mapped by circumnavigating the perimeter on foot while carrying a Garmin GPS (Etrex30) to record the track. When mapping the perimeter of the subcolonies, generally an average buffer distance of 2.5 meters was maintained between the mapper and breeding birds. However on Klung Island one of the mappers was mapping at a distance between 3 and 5m. Buffer distances were reduced accordingly for the varying tracks to produce a combined average buffer distance of 2m in the final layer. Given this the boundary mapping for these two islands may vary in accuracy. Note when mapping was undertaken at Peterson Island (74507) two subcolonies were not mapped when compared to mapping in the 13/14 season. The larger of these colonies was missed but the smaller colony did not exist in the 15/16 season.

An occupancy survey in November 2006 found a total of 29 islands in the Robinson Group of islands had populations of breeding Adelie penguins. The boundaries of breeding colonies at 27 of these were mapped in Nov 2006 for abundance surveys. Nine of these breeding sites were remapped on the 29th of November 2013 in conjunction with colony counts. Subcolonies were mapped by circumnavigating the perimeter of sub-colonies on foot while carrying a Garmin GPS (Legend Cx) to log the track taken. The person walking around the sub-colonies maintained a buffer distance of approximately 2.5m between themselves and the breeding birds along the sub-colony boundary. This buffer distance was reduced to approximately 2m in the final shapefiles.

The dataset comprises Adelie penguin colony boundaries derived from oblique aerial photographs. The aerial photographs were geo-referenced to AAT coastline polygon data and the boundaries of Adelie penguin colonies were digitised.

The dataset comprises scanned copies of the boundaries of Adelie penguin breeding colonies and sections of island coastlines made from aerial photographs taken between 9-15 December 1981. The original tracings by Michael Whitehead were scanned by Colin Southwell.
