NERC EDS UK Polar Data Centre. https://doi.org/10.5285/e3dee1ae-2892-4624-93c5-83fd3af69be6 This dataset comprises Argos PTT data for Adelie penguins, Pygoscelid adeliae, at Signy, Powell and Laurie Islands, part of the South Orkney Islands, between December and January 1999-2014. Tags were deployed across the South Orkney Islands (Signy Island, Powell Island and Laurie Island) between December and January (austral summer). The tracking data encompasses the breeding and post-breeding migratory dispersal of chinstrap penguins. The data includes coordinates for satellite uplinks for each tag and respective trip, along with error values for each satellite uplink. Metadata includes additional information about nesting and morphology, when available. PTT tags were deployed by British Antarctic Survey (BAS) personnel and supported by Natural Environment Research Council (UK) core funding and WWF grant GB095701 No credit. completed Trathan, Philip British Antarctic Survey Researcher author Warwick-Evans, Victoria British Antarctic Survey Researcher author Dunn, Michael British Antarctic Survey Researcher author Brown, Steve Researcher author Croxall, John Researcher author Morgan, Ash Researcher author Reid, Keith Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR) Researcher author Smith, Duncan Researcher author NERC EDS UK Polar Data Centre +44 (0)1223 221400 British Antarctic Survey, High Cross, Madingley Road Cambridge Cambridgeshire CB3 0ET United Kingdom PDCServiceDesk@bas.ac.uk https://www.bas.ac.uk/team/business-teams/information-services/uk-polar-data-centre/ information pointOfContact asNeeded completed EARTH SCIENCE > Biosphere > Ecological Dynamics > Competition EARTH SCIENCE > Biosphere > Ecological Dynamics > Consumption EARTH SCIENCE > Biosphere > Ecological Dynamics > Feeding Habitat EARTH SCIENCE > Biosphere > Ecological Dynamics > Food-web Dynamics EARTH SCIENCE > Biosphere > Ecological Dynamics > Indicator Species EARTH SCIENCE > Biosphere > Ecological Dynamics > Migratory Rates/Routes EARTH SCIENCE > Biosphere > Ecological Dynamics > Population Dynamics EARTH SCIENCE > Biosphere > Ecological Dynamics > Post-breeding EARTH SCIENCE > Biosphere > Ecological Dynamics > Trophic Dynamics theme Global Change Master Directory (GCMD) Science Keywords 2026-01-27 publication 23 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) Greenbelt MD United States of America https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

Each PTT was fitted to the lower medial portion of the back of each penguin using Tesa tape, plastic cable ties and quick-set epoxy resin ensuring the position of the device did not hinder the bird's movement, or access to their preen gland. Each bird was restrained according to BAS procedure. Device specifications for each deployment year are specified below. Additional information when known is also provided. 1999-2001: Deployment: 18 birds fitted with devices from mid-December to mid-February. Device: SirTrack ST-10 (97g) or SirTrack ST-18 (97g), 115 x 44 x 15 mm, 90-degree antenna 2004-2005: Deployment: 9 birds fitted with devices in December. Handling did not exceed 10 min. Each bird was restrained using a net, according to existing BAS procedure. Device: KiwiSat 101 transmitters (125x43x20 mm, 107 g) or KiwiSat ST10 transmitters (135x32x18 mm, 107g) Each PTT was set to transmit every 45 s and was equipped with a saltwater switch, which stopped the instrument from transmitting after a 3-h period out of water (a means of conserving battery power), only reactivating after re-submergence. Recovery: Following the attachment procedure, the penguins were released close to their nest sites. All devices were lost during the moult. 2012-2014: Deployment: 25 birds fitted with devices in January. Handling did not exceed 10 min. Each bird was restrained using a net, according to existing BAS procedure. Device: Devices (KiwiSat 101 transmitters (125x43x20 mm, 107 g) or KiwiSat ST10 transmitters (135x32x18 mm, 107g). Each PTT was set to transmit every 45 s and was equipped with a saltwater switch, that reduced the transmission rate when the bird hauled out of the water, either on land or on ice. The reduced transmission rate was intended to conserve battery power. Data quality: Satellite uplinks are given error values as the loc_class and loc_ind, which have an associated readme file further describing their values. The loc_class field indicates an error value for the location which is determined by the number of satellites the tag connected to. The loc_ind field indicates the IQ (quality indicator), which gives information on the transmitter in terms of X and Y. PTT location data were obtained from the ARGOS system (www.argossystem.org). Deployment data is filtered to include uplinks within trip duration provided in the metadata. When trip start and end timestamps were not provided, the first and last uplink for that deployment were used. asNeeded completed
