GPS fixes for foraging Southern Giant Petrels (Macronectes giganteus) breeding in Nelson Island, Maritime Antarctic Peninsula (December 2019-January 2020)

| Summary: | In the ZIP file there are two files. One is a .csv with GPS fixes processed using the adehabitatLT to identify events of low speed and high turn movements categorized as foraging. Points within a 250m radius from the breeding colony were excluded, and foraging trips were estimated based on the moment the animals crossed such a radius. Each foraging point was classified as being on land, within 5kms of coastline or on pelagic waters, and on different levels of Sea Ice Cover (from Bremen Sea Ice Remote Sensing data browser https://seaice.uni-bremen.de/databrowser/, Spreen, G., L. Kaleschke, and G.Heygster (2008), Sea ice remote sensing using AMSR-E 89 GHz channels J. Geophys. Res.,vol. 113, C02S03, doi:10.1029/2005JC003384). Second file is a R Script with details of the methods for processing the data. Two types of devices were used: Kite-M (Ecotone, NAV individuals) and Axy Trek Marine (Techno SmArt, HP individuals) configurated to collect points each 5 and 10 minutes, respectively. Funded by Fondecyt Iniciación (111 801 75) and Programa Áreas Marinas Protegidas del Instituto Antártico Chileno (24 03 052). |
