AAS_4088_Adelie_occupancy_Balaena
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
An occupancy survey on 26 January 2012 found 1 island (70166) along the coast between 111 degrees 00'E - 111 degrees 10'E had populations of breeding Adélie penguins. The survey was conducted from a fixed wing aircraft and oblique aerial photographs were taken of the occupied site. The aerial photographs were geo-referenced to the coastline shapefile from the Landsat Image Mosaic of Antarctica (LIMA, tile E158) and the boundaries of penguin colonies were digitised from the geo-referenced photos with not intentional buffer. Note the quality of the aerial photos was poor and so the resultant boundary mapping will not be very accurate. Also in the Balaena Islands there is a historic record from the 50s of penguins nesting on Thompson Islet (70166). When aerial photos were taken of this island penguins could not be detected.

Quality
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 (e.g. Vestfolds and Rauers) or ground survey (e.g. Robinsons).
