This dataset comprises a table and set of maps of all geographic sites of ice-free land along the East Antarctica coastline between longitudes 37°E and 160°E. Each geographic site comprises a discrete area of ice-free land and includes islands within 100 km of the coast and outcrops of ice free continental rock within 1 km of the coast. The geographic sites were identified in a geographic information system using polygons sourced from the AAT Coastline 2003 dataset produced by Geoscience Australia and the Australian Antarctic Division, and exposed rock polygons sourced from the Antarctic Digital Database version 4.0 produced for the Scientific Committee on Antarctic Research. The maps are grouped into sub-regions and regions, with multiple maps in most sub-regions. The maps were designed to be of a scale that could be used in the field to identify sites by their shape and location. This dataset has previously been used in the specific context of potential breeding habitat for Adelie penguins (doi:10.4225/15/5758F4EC91665) but has potential for broader use in a wide range of ecological and environmental studies. 2021-06-30 - an updated copy of the spatial reference system spreadsheet was uploaded. The update was only minor.

This dataset collates data on occupancy of geographic sites by breeding Adelie penguins across east Antarctica between 37 degrees E -160 degrees E from the 1950s to the present day. A separate dataset contains a table and maps of geographic sites in East Antarctica where Adelie penguins could potentially breed. This occupancy dataset comprises a table of breeding sites and a table of occupancy observations. The breeding site table has a list of the geographic sites where breeding Adelie penguins have been observed at least once. The table contains for each breeding site, the names used for each site in the literature, the literature sources for those names, the geographic centroid of the breeding location within the geographic site, and any comments to help interpret the breeding site. The occupancy table contains observations of the presence or absence of breeding Adelie penguins at each breeding site and split-year breeding season obtained from the published primary and secondary literature and from the researchers' unpublished data. These data also include occupancy survey data collected as part of ASAC 2722 - see the related metadata record for more information.
