GPS fixes for foraging Southern Giant Petrels (Macronectes giganteus) breeding in Nelson Island, Maritime Antarctic Peninsula, 2021 to 2023

This dataseta contain tracking data of breeding Southern Giant Petrels (Macronectes giganteus) collected from december to february in Harmony Point (Nelson Island, South Shetland Islands) in 2021/22 and 2022/23 breeding seasons. Cat-Log 2 (Perthold Engineering) and Sputnik (Sextant Technology) devices were used, consisting of 5-minute interval GPS fixes (a few animals had 10 minutes fixes, they are easy to spot by checking data). Capture and deployment followed protocols evaluated by ethical commitees of Universidad de Magallanes and Instituto Milénio of Biodiversity of Antarctic and Subantarctic Ecosystems (BASE), with environmental permits emmited by Instituto Antártico Chileno. Two files are available: one on .csv format, and another one in .Rds that can be opened in R maintaining data carachteristics, for instance, date (TS column) is in a POSIXct timpestamp format, and it is maintained within the file. Each animal was ringed with stainless steel rings; ring numbers correspond to the BirdId column. Production of this dataset was supported by the Instituto Antártico Chileno, Programa Áreas Marinas Protegidas (AMP 24 03 052), ANID – Programa Iniciativa Milenio – ICN2021_002 (BASE)
