Description
These represent the speed filtered GPS dataset and associated CRAWL models (R package crawl, v2.2.1) for 83 individual Chinstrap penguins instrumented between November 2018 and February 2019 at Deception Island at Bailey Head and Macaroni Point. Each individual penguin has a unique identifier (D_Rxx_Pxx) The data is tidy (one row = 1 observation = 1 location) and clean (no NAs; no duplicated lines, tracks cut off by deployment date + 24h and recovery date; points less than 2 min apart were removed for D_R4_P10). Each track is matched to the individual penguin metadata (ID, instrument type, deployment, recovery dates, original file, breeding status) The data is stored as a tibble in a R environment, contains 84,550 GPS locations and 24 columns. The GPS locations are available unprojected (lat lon " +proj=lonlat +ellps=WGS84 +datum=WGS84"; EPGS 4326) and projected in Polar stereographic (+proj=stere +lat_0=-90 +lat_ts=-71 +lon_0=0 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs; EPSG:3031). Also included are pdf images of individual tracks, and the shapefile (polygon) of Deception Island used as a mask.
