This dataset consists of two shapefiles created by Darren Southwell of the Australian Antarctic Division (AAD) by digitising the boundaries of adelie penguin colonies at the Rauer Group and the Vestfold Hills. The digitising was done from images resulting from the scanning and georeferencing of aerial photographs taken on 24 November 1993. The aerial photographs were taken for the AAD with a Linhof camera. Records of the photographs are included in the Australian Antarctic Data Centre's Aerial Photograph Catalogue.

Ship-based observations of birds, seals and whales from the original 'ANARE Bird Log' books have been recovered into a single repository of sightings and associated abiotic information. ANARE (Australian National Antarctic Research Expeditions) is the historic acronym for these voyages. A few voyages have been included that were not part of ANARE but have Australian observers or volunteer observers. Voyages start from the 1947/48 austral season up to 1982/83 with an average of 3 voyages per season. There are a few voyages where there is no data. It is not known if either no bird observations were undertaken during this period or that the bird logs exist if observations were undertaken. Current counts are birds, seals and whales Observing platforms include the following ships - Wyatt Earp, Tottan, River Fitzroy, Norsel, Kista Dan, Thala Dan, Magga Dan, Nella Dan, Lady Franklin and Nanok S and a single voyage from the private yacht Solo. The quality and quantity of abiotic data associated with observations such as air temperature, sea ice cover etc vary immensely from voyage to voyage. Where possible this data has been entered. This dataset contains very little information on estimates of survey effort and cannot be used to derive useful presence/absence spatial coverages of species during this period. It is purely sighting data only.

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 Adelie 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.

Australian Bird and Bat Banding Scheme Bird Banding records from the Australian Antarctic Territory and Heard Island, a subset of banding and recovery records from within Australian Antarctic Territory and Heard Island. The Australian Government under the auspices of the Australian Bird and Bat Banding Scheme (ABBBS) manages the collation of information on threatened and migratory bird and bat species. The information provided spans from 1953 to the present, and contains over 2 million records. This set comprises records of banding and recovery in the Australian Antarctic territory. Records are also included if the bird was recovered or banded outside this region. The ABBBS site is at http://www.environment.gov.au/science/bird-and-bat-banding.

Adelie colony boundaries at Bechervaise Island were mapped by Matthew Pauza on the 21 Dec 2016. Subcolonies were mapped by circumnavigating the perimeter on foot while carrying a Garmin GPS (Etrex30) to record the track. When mapping the perimeter of the subcolonies a buffer distance of approximately 2.5 meters was maintained between the mapper and the breeding birds. This buffer distance was reduced by .5m to between 2m in the final shapefiles.

The only work that went ahead as part of this ASAC project was to look at Penguins restraint and stress level (see the referenced paper below). From the paper: During most research on penguins it is necessary to temporarily immobilise the birds at some time (to weigh, mark, or attach instruments). Although many penguin species seem unconcerned about a human's presence, a single approaching person has been shown to increase the birds heart rate, suggesting that the animal is aware and may be stressed. Corticosterone is one of the hormones regulating the stress reaction in birds, and in turn regulates that stress caused by immobilisation. As captured and bag restrained Adelie penguins show a three fold increase in heart rate, we can presume that this is a very stressful immobilisation technique. Restricting the stress reaction is particularly important during the breeding season to avoid nest desertion, or loss of eggs and chicks. The subject of this paper is to present a less stressful method for restraining penguins. 38 mature, male Gentoo penguins in good physical condition were used to test bag restraint methods. Resting animals were caught on the Macquarie Island Isthmus. 59 animals were used to test the effect of hood restraint methods. There was a significant increase in corticosterone concentrations in the blood of bag restrained penguins within 10 minutes of restraint. Between 10 and 15 minutes, further changes were not significant. After 20 minutes, however, there was a second significant increase, when compared to the levels at 15 minutes. Upon release all birds were unconscious; they then showed symptoms of hysteria, such as disorientation and shaking of the head. Corticosterone levels in the blood of hooded penguins rose significantly after 5 minutes. After 10 minutes, the mean concentration showed a tendency to decrease, when compared to the 5 minute levels. This, however, did not differ significantly to concentrations immediately after restraint. After 20 minutes concentrations rose again, and were again significantly higher than at the same time of restraint and after 15 minutes. Both groups showed the same levels of corticosterone upon restraint. Hood restraint led overall to a lower increase in corticosterone levels than restraint with a bag. After 5, 10, 15 and 20 minutes, statistically significant lower levels in the blood were detected in hood restrained birds. The penguin's reaction to both restraint methods was identical in two respects: There was no significant increase in corticsterone concentration between 10 and 15 minutes. Secondly, concentrations were significantly higher after 20 minutes than at 15 minutes.

This file contains a log of observations collected in the Casey region between 1972 and 1973. Observations were made of Seals (Weddell seals, Elephant seals, Leopard seals) and Adelie penguins. The hard copy of the log has been archived by the Australian Antarctic Division library.

Adelie penguin foraging trip duration records for Bechervaise Island, Mawson since 1991-92. Data include average male and female foraging trip durations for both the guard and creche stages of the breeding season. Data based on records of tagged birds crossing the APMS for in and out crossings. Durations determined from difference between out and in crossings in conjunction with nest census records. Data included only for birds which were known to be foraging for a live chick. This work was completed as part of ASAC Project 2205, Adelie penguin research and monitoring in support of the CCAMLR Ecosystem Monitoring Project. The fields in this dataset are: Year trip duration (hours) Mean , standard error, count and standard deviation for male and female foraging trips during guard and creche stages of the breeding season.

This file contains a biology report from Wilkes station in 1968. As well as a report, the file also contains correspondence and some banding data. Much of the information appears to relate to Adelie Penguins and South Polar Skuas. The hard copy of the file has been archived by the Australian Antarctic Division library.
