NERC EDS UK Polar Data Centre. https://doi.org/10.5285/da13e049-be2b-4345-bbdd-ab960cb24731 This dataset comprises Time-Depth Recorder (TDR) tracks of chinstrap penguins, Pygoscelid antarcticus, at the South Orkney Islands (Signy, Monroe, Powell and Laurie Island) from 2011 to 2019. Chinstrap penguins were fitted with TDR tags between December to January (austral summer) to better understand their movement for seabird conservation and management. The data includes temperature and pressure at specified intervals for deployed tags, with additional metadata on the morphology of the birds, their deployment, and breeding. Work was carried out by personnel at the British Antarctic Survey (BAS) and was funded by Natural Environment Research Council (UK) core funding to BAS. This is an updated version of a previous dataset. There have been additional tracks included with further quality control carried out.

Breeding penguins were caught during incubation, brood and creche periods and fitted with TDR loggers (Lotek LAT 1810 or CEFAS G5s) using Tesa tape and a two-part quick-setting glue. Handling time did not exceed 10 minutes for deployment and 5 minutes for retrieval. Loggers were always less than 1 percent of the bird's body mass. Devices were retrieved on average after 4.7 days. Data includes temperature, pressure and a timestamp. The number of deployed tags with data per year are as follows: Signy Island: 2011 -2012: 11 2013-2014: 25 2015-2016: 28 2018-2019: 59 Laurie Island: 2011-2012: 60 Monroe Island: 2015-2016: 65 Powell Island: 2013-2014: 68 Data collection: Lotek LAT 1810 (6 g in air, 38 x 11 mm) CEFAS G5s (either 2.7 g in air, 31 x 8 mm; or 6.5 g in air, 35 x 12 mm) Data quality: Files were consolidated to include only the timestamp, pressure in dBars, and temperature in degrees Celsius. When known, the temperature was recorded as internal, external or both. If not known, the temperature is recorded as 'Temperature'. Internal temperature relates to the sensor inside of the instrument, whereas the external temperature means the sensor was on the outside of the instrument. This is a version 2 of a previous dataset, that included GPS and TDR tags together. Errors found in the metadata and data were rectified in this version, which also includes a broader spatial and temporal coverage of tracks. Where the sex of the bird was not known, 'U' was used in the metadata file. asNeeded completed
