It was not possible to geo-reference oblique photos to coastline shapefiles perfectly. The colony boundaries are less accurate than those derived elsewhere in east Antarctica from vertical aerial photography (eg Vestfolds and Rauers) or ground survey (eg Robinsons). An occupancy survey in 26 January 2012 found a total of 2 islands along the coast between 120o30’E - 121o02’E had populations of breeding Adelie penguins. The survey was conducted from a fixed wing aircraft and oblique aerial photographs were taken of each occupied site. The aerial photographs were geo-referenced to the coastline shapefile from the Landsat Image Mosaic of Antarctica (LIMA, tile E159) and the boundaries of penguin colonies were digitised from the geo-referenced photos. Details for each island are: Chick: Photographs taken on 26 January 2012 and geo-referenced to LIMA tile E159 Henry 1: Photographs taken on 26 January 2012 and geo-referenced to LIMA tile E159
