DarwinPlus053: Northern Rockhopper penguin Eudyptes moseleyi GLS data from Nightingale Island, Tristan da Cunha, 2016-2017
Darwin Plus Project 053 Nightingale Island, Tristan da Cunha http://www.darwininitiative.org.uk/documents/DPLUS053/24132/DPLUS053%20AR1%20-%20edited.pdf The dataset is under Embargo until data analysis has been completed and ready to be published as Open Data. Geolocators (GLS) were attached to northern rockhopper penguins breeding on Nightingale Island (37°25'S, 12°28'W; 4 km2) with the aim to study the species’ dispersal in the inter-breeding period, 2017. This data successfully augmented and complement existing data sets for the species breeding on Nightingale Island and enhanced our understanding of the species’ distribution at sea throughout their annual cycle. There are four different data types for each penguin a) the unprocessed light sensor data, b) the unprocessed activity (wet/dry) data, c) the unprocessed temperature data and d) the estimated positions using the BAStag and SGAT packages in R. Data were collected as part of the Darwin Plus funded Project Pinnamin, 2016 – 2018, a joint multi-institutional and interdisciplinary collaboration between the RSPB, Tristan da Cunha government, British Antarctic Survey (BAS), Royal Zoological Society of Scotland (RZSS) and the Department of Environmental Affairs (DEA) in South Africa.

Positions during the non-breeding season were estimated from Global Location Sensing (GLS) loggers, which allows for the estimation of latitude and longitude from daylight measurements. Data were downloaded from MigrateTech GLS tags using proprietary MigrateTech software. Subsequently data were decompressed using the BAStrack software ‘decompressor’. Clock drift was accounted for using the start time of each tag. Loggers measured light levels every xxx seconds recording the maximum light level in a 10 minute period. Salt-water immersion was assessed every xx s and the number of positive tests in each 10 min interval recorded: an immersion value of 0 indicates that the logger was completely dry and 200 that it was completely wet. Processed Estelle data was created from the light data using the BAStag and SGAT packages in R. There are four different data types for each penguin a) the unprocessed light sensor data .lux, b) the unprocessed activity (wet/dry) data .ral, c) the unprocessed temperature data .deg and d) the estimated positions using the BAStag and SGAT packages in R (.csv).
