  • This dataset contains data on the habitats, distribution and numbers of Adelie Penguins (Pygoscellis adeliae) along the Vestfold Hills coast (including colonies on the mainland and offshore islands) during November 1973. The data are obtained from counts at the colonies and black and white photographs. Some aerial photographs were taken at Davis in 1981-82 and 1987-88, and will be compared to the results of this survey. The results are listed in the documentation. A total of 174178 26127 breeding pairs were counted. An increase in Adelie penguin population was found at most locations in East Antarctica. Data from this record has been incorporated into a larger Adelie penguin dataset described by the metadata record - Annual population counts at selected Adelie Penguin colonies within the AAT (SOE_seabird_candidate_sp_AP). It also falls under ASAC project 1219 (ASAC_1219).

  • This dataset comprises counts of Adelie penguins attending breeding sites from images obtained with 20 remotely operating cameras across East Antarctica. Counts were made of adults, occupied nests and chicks every few days throughout the breeding season from October through to February. Locations of cameras are given in an associated dataset (Photographic images of seabird nesting sites in the Antarctic, collected by remote camera) which also provides the images obtained from the cameras. Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data.

  • 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.

  • Distribution, abundance and dates of relict Adelie Penguin colonies in the Australian Antarctic Territory (AAT). Current mapping efforts have focused on the Windmill Islands in preparation for a PhD study to commence in 2004/05 with the two investigators. The planned PhD study will work at either the Windmill Islands or the Vestfold Hills. This project integrates ASAC projects 1219 and 1322 (ASAC_1219, ASAC_1322).

Uncorrected Date (BP) - (day) Standard Deviation Delta R - range of corrected date for sample, 2 standard deviations either side of the mean Mean - estimated mean of sample date See the paper included in the download file for further information.

  • This dataset contains data on the habitats, distribution and numbers of Adelie Penguins (Pygoscellis adeliae) in the Mawson area, Antarctica during 1981 and 1988. The data are obtained from aerial photographs obtained at various times, during the 1981-82 and 1988-89 seasons. The results are listed in the documentation. Comparisons are made with census data collected in the 1971-72 summer. Data from this record has been incorporated into a larger Adelie penguin dataset described by the metadata record - Annual population counts at selected Adelie Penguin colonies within the AAT (SOE_seabird_candidate_sp_AP). It also falls under ASAC project 1219 (ASAC_1219).

  • The relationship between colony area and population density of Adelie Penguins Pygoscelis adeliae was examined to determine whether colony area, measured from aerial or satellite imagery, could be used to estimate population density, and hence detect changes in populations over time. Using maps drawn from vertical aerial photographs of Adelie Penguin colonies in the Mawson region, pair density ranged between 0.1 and 3.1 pairs/m2, with a mean of 0.63 - 0.3 pairs/m2. Colony area explained 96.4% of the variance in colony populations (range 90.4 - 99.6%) for 979 colonies at Mawson. Mean densities were not significantly different among the 19 islands in the region, but significant differences in mean pair density were observed among colonies in Mawson, Whitney Point (Casey, East Antarctica) and Cape Crozier (Ross Sea) populations. This work was completed as part of ASAC project 1219 (ASAC_1219). The fields in this dataset are: Island Latitude Longitude Date Colony area Breeding Pairs Breeding Pairs per square metre Area per nest Number of nests Number of adults

  • This dataset comprises the actual video footage and audio recordings made during a number of experiments made as part of ASAC project 1148 (ASAC_1148). The primary objective was to measure the responses of Antarctic wildlife to various human disturbance stimuli. An excel spreadsheet of a catalogue of the video and audio tapes is available for download from the url given below. The video and audio tapes themselves are stored at the Australian Antarctic Division. For descriptions of (and access to) processed data see the metadata records with the following titles: Measuring the effects of human activity on Weddell Seals (Leptonychotes weddellii) Effects of helicopter operations on emperor penguin chicks Effects of helicopters on Southern Antarctic Fulmars Effects of helicopters on Antarctic wildlife Effects of human activity on Gentoo penguins on Macquarie Island Effects of human activity on King penguins on Macquarie Island Effects of human activity on Royal penguins on Macquarie Island Behavioural responses of Weddell seals to human activity. A copy of the full dataset of video and audio files, as well as another Excel spreadsheet catalogue is available for download from the provided URL. These data were digitised in 2021, and the excel spreadsheet created from the available files.

  • This study aimed to quantify the effects of helicopter operations on Antarctic wildlife, with an emphasis on determining minimum safe over-flight altitudes and landing distances for a range of species. An experimental approach was adopted whereby wildlife were exposed to helicopters either over-flying or landing at specific altitudes or distances while the behaviour, and in some cases physiology, of individual animals were recorded. Two types of helicopters were used in the study: a Sikorsky S-76 (twin engine) and a Squirrel AS350 (single engine). This metadata record relates to the responses of Adelie Penguins (Pygoscelis adeliae) over a number of phases of their breeding cycle. The fields in this dataset are: Time Action Date
