DarwinPlus053: Northern Rockhopper penguin Eudyptes moseleyi GPS data from Nightingale and Inaccessible islands, Tristan da Cunha, 2016

Abstract

Darwin Plus Project 053 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. Global Positioning System (GPS Pathrack) data loggers were attached to breeding northern rockhopper penguins during incubation, guard and crèche stages between September to December 2016 on Nightingale (37°25'S, 12°28'W; 4 km2) and Inaccessible (37°17'S, 12°40'W; 14 km2) islands. Tracking data augmented and complement existing data sets for the species breeding in the South Atlantic, which enable us to systematically identify areas of particular relevance for this species and thus to help determining whether there is a need to improve marine spatial planning in form of e.g. Marine Protected Areas in the island’s EEZ. There are two data types for each penguin a) the unprocessed raw and b) the processed GPS data (details below). All files are in the CSV format. 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.

Quality and validity

Lineage

Data were downloaded and analysed using R (version 3.4.0, R Development Core Team). Erroneous GPS locations were filtered by the speedfilter function (trip package, Sumner 2015) when speed exceeded 8km/h and duplicate positions removed. When devices recorded consecutive trips, data were separated into foraging trips, which were described by last and first recorded position back at the colony using QGIS (QGIS Development Team). To compensate for irregular gaps between positional fixes within the tracks, filtered data were subsequently processed using a continuous, time-correlated random walk model (crawl package, Johnson et al. 2008). Based on the simulation of 100 possible tracks the most likely or ‘best fit’ path used by the penguin is generated.
