Metadata details
ASAC_2722_Occupancy_Surveys
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
The current distribution of Adelie penguin breeding colonies in the AAT is being mapped through a series of 'occupancy' surveys.
A GIS of potential Adelie penguin breeding habitat was developed to structure the overall search effort. Information about the GIS is given in Southwell et al. (2009) and in the related metadata record 'Sites of potential habitat for breeding Adelie penguins in East Antarctica' with Entry ID AAS_4088_Adelie_Potential_Habitats.
The AAT coastline was broken into groups and subgroups which were surveyed when logistics allowed. All sites of potential habitat in each section were searched and a record of whether breeding penguins were present or absent was made. Most surveys were undertaken during the Adelie penguin breeding season when breeding penguins would have been present; any surveys outside the breeding season made observations of the presence or absence of guano. Most surveys have been undertaken from aircraft (both helicopters and fixed wing), but some have been done from the ground.
Maps of potential breeding habitat in the groups and subgroups were produced from the GIS to use in the field surveys. The data recorded for each search campaign included the latitude and longitude of the centroid of each site that was searched, the data of search, the observer(s), and the state of occupancy (present or absent).
These data were incorporated into the occupancy surveys undertaken as part of AAS project 4088. See the metadata record for that project to access the data (at the provided URL).
