The RAATD project team consolidated tracking data for multiple species of Antarctic meso- and top-predators to identify Areas of Ecological Significance. These datasets constitute the compiled tracking data from a large number of research groups that have worked in the Antarctic since the 1990s. This metadata record pertains to the "standardized" version of the data files. These files contain position estimates as provided by the original data collectors (generally, raw Argos or GPS locations, or estimated GLS locations). Original data files have been converted to a common format and quality-checking applied, but have not been further filtered or interpolated. Periods at the start or end of deployments were identified and discarded if there was evidence that location data during these periods did not represent the animals' at-sea movement. For example, tags may have been turned on early (thereby recording locations prior to their deployment on animals) or animals may have remained at the deployment site, e.g. the breeding colony, for an extended period at the start or end of the tag deployment. Some tracks also showed a marked deterioration in the frequency and quality (for PTTs) of location estimates near the end of a track. Such locations were visually identified based on maps of each track in conjunction with plots of location distance from deployment site against time. This information is captured in the location_to_keep column appended to each species’ data file (1 = keep, 0 = discard). The code used to trim the tracks can be found in the https://github.com/SCAR/RAATD repository. This data set comprises one metadata csv file that describes all deployments, along with data csv files (17 files, one per species) containing the position data. For details of the file formats, consult the data paper. The data are also available in a filtered version (see https://data.aad.gov.au/metadata/records/SCAR_EGBAMM_RAATD_2018) that have been processed using a state-space model in order to estimate locations at regular time intervals. {"type": "Polygon", "coordinates": [[[-180.0, -90.0], [180.0, -90.0], [180.0, -20.0], [-180.0, -20.0], [-180.0, -90.0]]]} -180.0 180.0 -90.0 -20.0 AMD AMD/AU AREAS OF ECOLOGICAL SIGNIFICANCE ARGOS > ARGOS Data Collection and Position Location System BIOTELEMETRY CEOS CONTINENT > ANTARCTICA > MAWSON RESEARCH STATION CONTINENT > ANTARCTICA > ROSS ISLAND CONTINENT > ANTARCTICA > SCULLIN MONOLITH CONTINENT > ANTARCTICA > SVARTHAMAREN CONTINENT > ANTARCTICA > TERRE ADELIE CONTINENT > ANTARCTICA > VESTFOLD HILLS EARTH SCIENCE > AGRICULTURE > ANIMAL SCIENCE > ANIMAL ECOLOGY AND BEHAVIOR EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > BIRDS > ALBATROSSES/PETRELS AND AL EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > BIRDS > PENGUINS EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > MAMMALS > CARNIVORES > SEALS/SEA L EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > MAMMALS > CETACEANS > BALEEN WHALE ECOLOGICAL DYNAMICS GEOGRAPHIC REGION > POLAR GLOBAL LOCATION SENSOR GPS > Global Positioning System Satellites HABITAT USE HOT SPOTS OCEAN > ATLANTIC OCEAN > SOUTH ATLANTIC OCEAN > BOUVET ISLAND OCEAN > ATLANTIC OCEAN > SOUTH ATLANTIC OCEAN > FALKLAND ISLANDS OCEAN > ATLANTIC OCEAN > SOUTH ATLANTIC OCEAN > SOUTH GEORGIA ISLAND OCEAN > INDIAN OCEAN > CROZET ISLANDS OCEAN > INDIAN OCEAN > KERGUELEN ISLANDS OCEAN > SOUTHERN OCEAN > BECHERVAISE ISLAND OCEAN > SOUTHERN OCEAN > CAMPBELL ISLAND OCEAN > SOUTHERN OCEAN > COULMAN ISLAND OCEAN > SOUTHERN OCEAN > DRESCHER INLET OCEAN > SOUTHERN OCEAN > FILCHNER TROUGH OCEAN > SOUTHERN OCEAN > HEARD AND MCDONALD ISLANDS OCEAN > SOUTHERN OCEAN > HUKURO COVE OCEAN > SOUTHERN OCEAN > ISLAS MALVINAS OCEAN > SOUTHERN OCEAN > MACQUARIE ISLAND OCEAN > SOUTHERN OCEAN > MCMURDO SOUND OCEAN > SOUTHERN OCEAN > PETREL ISLAND OCEAN > SOUTHERN OCEAN > PRINCE EDWARD ISLANDS OCEAN > SOUTHERN OCEAN > SIGNY ISLAND OCEAN > SOUTHERN OCEAN > SOUTH SHETLAND ISLANDS OCEAN > SOUTHERN OCEAN > UFS ISLAND PLATFORM TERMINAL TRANSMITTERS SATELLITES SEALS TRACKING GET DATA > DIRECT DOWNLOAD documentDigital Download the standardised tracking data HTML VIEW RELATED INFORMATION documentDigital Citation reference for this metadata record and dataset.
