TDR tracks of Adelie penguins at Signy Island, South Orkneys Islands, 2011-2016

GB/NERC/BAS/PDC/02018

Abstract:
This dataset comprises Time-Depth Recorder (TDR) tracks for Adelie penguins, pygoscelid adeliae, at Signy Island, South Orkneys Islands, from December 2011 to January 2016 (austral summer). Adelie penguins were fitted with TDR tags at Signy Island 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.

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. Where the sex of the bird was not known, 'U' was used in the metadata file.
Lineage/Methodology:	Temperature-Depth recorder (TDR) devices were fitted to 51 Adelie penguins on Signy Island over three seasons between December and February, 2011 to 2019. 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 tags with data per year are as follows: 2011-2012: 12 2013-2014: 23 2015-2016: 11

Storage

Data Storage:	Deployment IDs given as the following: Two code abbreviation for the island + one letter code for the species + deployment number Two-code abbreviation: Signy Island: SI Adelie penguin: A Deployment IDs were used as file names. File names include '_TDR' abbreviation. Deployment IDs match with related GPS dataset. Files that are linked have the same filename except for the last abbreviation: GPS or TDR. Deployment ID structure also matches related datasets on GPS and TDR tracks for other pygoscelids tracked from the South Orkney islands. 48x .csv files with data (1 per deployment) 1x .csv file with metadata 1x. txt file with header metadata including citation and DOI
