Two colonies with breeding Adelie colonies were mapped this season in the Rookery Island group 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 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.

Fourteen colonies with breeding Adelie colonies were mapped this season in the Rookery Island group between the 29th November and 14th of December 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 Gibbney and Rookery 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 on Gibbney and Giganteus there were at least two subcolonies on both islands that were mapped but the density of breeding birds in these mapped sections was much less than that in the surrounding colonies. Subcolonies were tagged with L at the end of their name in the track files. This will not be shown in the final layer and if information on this is needed then the subcolonies can be identified from the original track data or created shapefiles for the individual subcolonies on the island.

Six colonies with breeding Adelie colonies were mapped this season in the Rookery Island group in conjunction with colony counts. Islands 74814 and the main Rookery Island 74721 were not mapped this season. 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.

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.

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.

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 islands with larger populations were subsequently mapped for abundance surveys by 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 2-5m between themselves and the penguins at the sub-colony boundary. This buffer distance was reduced to between 1 and 4m in the final shapefiles.

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.

Occupancy surveys in November 2009 and December 2010 (Southwell and Emmerson 2013) found a total of 15 Adelie penguin breeding sites in the Svenner Islands between longitudes 76.50oE to 77.50oE. The boundaries of breeding sub-colonies 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. When photos of Island 73036 were viewed there was no colony to map so only 14 islands were mapped.

An occupancy survey in December 2009-February 2010 and January 2011 found a total of 6 islands along the Knox coast had populations of breeding Adelie penguins. The survey in 2009/10 was conducted from a fixed wing aircraft and oblique aerial photographs were taken of occupied sites. The aerial photographs were geo-referenced to satellite images or the coastline shapefile from the Landsat Image Mosaic of Antarctica (LIMA, tile E157) and the boundaries of penguin colonies were digitised from the geo-referenced photos. Details for each island are: Merrit: Photographs taken on 1 February 2010 and geo-referenced to LIMA tile E157 Cape Nutt: Photographs taken on 5 January 2010 and geo-referenced to a Quickbird satellite image taken on 17 February 2011 Ivanoff Head: Photographs taken on 27 December 2009 and geo-referenced to LIMA tile E157 Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data.
