The factors that control the number of animals in a population are often difficult to understand. However, this basic understanding is central to managing those populations and assessing how they might respond to human induced pressures. For animals living in the Antarctic, like penguins, the marine environment that they depend on for food can vary due to natural events such as El Nino, and potentially due to human induced changes such as global warming. This study uses modern computer technology to track Royal penguins at sea and to monitor their time on land. By relating where the birds go to feed, what they feed on, and how successfully they catch their food to the survival rates of their chicks, this study will describe how fluctuations in a major Antarctic oceanographic feature (the Antarctic Polar Front) can influence the size of the Royal penguin population at Macquarie Island. Information on breeding success, diet and foraging success were collected each year between 1997-2001. Diving behaviour and at-sea movements were also quantified between 1997 and 1999. These data will also be available in the ARGOS satellite tracking database. Attached to this metadata record are ARGOS tracking data collected by Cindy Hull between 1994 and 2000. The tracking data have been collected from 19 different royal penguins. The download file contains a csv file with tracking data.

The dataset comprises records of crossings by Adelie penguins of a weighbridge and gateway established on Bechervaise Island. The weighbridge and gateway are positioned so that most or all of the penguins breeding in a set of sub-colonies on the island cross the weighbridge when they leave the colony to forage and when they return from foraging. The gateway records the time of each crossing, the dynamic weight of the penguin as it crosses, and the identity of penguins that have been sub-cutaneously tagged. The weighbridge and gateway operate continuously throughout the austral breeding season. The data are currently in an unprocessed form.

During the 2015 New Zealand-Australia Antarctic Ecosystem Voyage a digital photogrammetric video tracking system was used to collect precise surfacing locations during encounters with some Antarctic blue whales. The photogrammetric video tracking system is a modern digital video version based on the same operating principle as the that described by Leaper and Gordon 2001, and enables determination of the range and bearing to tracked objects relative to the ship. Around 15 hours of video tracking were recorded of which 8 hours were classified as good quality of a single animal or in one case a pair of animals that stayed close together. Focal follows were aborted when it was no longer possible to follow the focal animal due to ice or when the presence of other animals meant it was no longer possible to be sure which was the focal animal. This resulted in 7 tracks of longer than 45 minutes with the longest around 2 hours. Leaper, R. and Gordon, J. 2001.

This record relates to the Australian component of the Latitudinal Gradient Project. The LGP is largely a New Zealand, US and Italian venture, but a small contribution has been made by Australian scientists. The Australian component of this work was completed as part of ASAC projects 2361 and 2682 (ASAC_2361, and ASAC_2682). Data from this project were entered into the herbarium access database, which has been linked to this record. The list below contains details of where and when samples were collected, and also the type of sample and the method of sampling. Cape Hallett and vicinity (2000, 2004): Biodiversity assessment of terrestrial plants (mosses, lichens); Invertebrate collections (mites, Collembola); plant ecology and community analysis; photosynthetic physiology of mosses and lichens; molecular genetics of mosses and lichens. Random sampling for biodiversity studies; point quadrats, releves for vegetation analysis, field laboratory experiments for physiological studies. Dry Valleys: Taylor Valley (1989, 1996), Garwood Valley (2001), Granite Harbour (1989; 1994, 1996) - plant ecology; plant physiology; biodiversity; invertebrate collections; molecular genetics of mosses. Random sampling for biodiversity studies; point quadrats, releves for vegetation analysis, field laboratory experiments for physiological studies. Beaufort Island (1996) - plant biodiversity; molecular genetics of mosses. Random sampling for biodiversity studies; point quadrats, releves for vegetation analysis, laboratory studies for molecular genetics. Darwin Glacier (1994): plant biodiversity; molecular genetics of invertebrates and mosses (random sampling for biodiversity; laboratory studies of invertebrate and moss molecular genetics). Project objectives: 1. Investigate the distribution of bryophytes and lichens in continental Antarctica 1a). to test the null hypothesis that species diversity does not change significantly with latitude; 1b). to explore the relationships between species and key environmental attributes including latitude, distance from the coast, temperature, substrate, snow cover, age of ice-free substrate. 2. To continue to participate in the Ross Sea Sector Latitudinal Gradient Project and develop an Australian corollary in the Prince Charles Mountains, involving international collaborators, incorporating the first two objectives of this project. 3. To develop an international collaborative biodiversity and ecophysiological program in the Prince Charles Mountains that will provide a parallel N-S latitude gradient study to mirror the LGP program in the Ross Sea region as part of the present RISCC cooperative program (to be superseded by the EBA (Evolution and Biodiversity of Antarctica) program) to address the above objectives. Taken from the 2008-2009 Progress Report: Progress against objectives: Continuing identification of moss and lichen samples previously collected from Cape Hallett, Granite Harbour and Darwin Glacier region. Lecidea s.l. lichens currently being studied in Austria by PhD student. Field work in Dry Valleys significantly curtailed by adverse weather. Field work planned for Darwin Glacier region and McMurdo Dry Valleys, particularly Taylor Valley and Granite Harbour region was severely curtailed due to adverse weather, helicopter diversions due to a Medical Evacuation, and other logistic constraints. 10 days of field time were lost. Limitations on field travel in Darwin Glacier region restricted the field work to a biologically depauperate region. The Prince Charles Mountains N-S transect, the only continental transect possibility for comparison with the Ross Sea area, unfortunately appears to have been abandoned through lack of logistic support. Taken from the 2009-2010 Progress Report: Identification of samples collected from AAT and Ross Sea Region continued during the year, interrupted significantly by the packing of the collection and transfer of specimens to the Tasmanian Herbarium. Work is now proceeding at the Herbarium with sorting, databasing and incorporation of packets into the Herbarium collection. The merging of the collection provides long-term security of curation and significantly boosts the cryptogam collections (35000 numbers) of the Tasmanian Herbarium.
