Data from: Aquatic behaviour of polar bears (Ursus maritimus) in an increasingly ice-free Arctic
Three data files associated with the manuscript "Aquatic behaviour of polar bears (Ursus maritimus) in an increasingly ice-free Arctic".
Data was collected by devices with a saltwater switch (and for diving, a pressure sensor) deployed on collars of female polar bears in Svalbard in 2005-2017.
1) Monthly_means.txt is a tab-separated text file with 818 records with the following columns: "id" (individual bear identifier), "month" (1-12), "year", "mean_proportion_wet" (monthly mean proportion of the time the collar recorded being submerged in water), "days" (length of recorded time this mean is based on, minimum 5 days), "reproductive_status" (whether the female had young of the year (c), yearlings (y), no cubs (n) in the preceeding april, or if this is not known (NA)), "offshore" (whether the bear made offshore excursions or not during their period of tracking).
2) Dive_depths.txt is a tab-separated text file with 51301 records with the following columns: "id" (individual bear identifier), "dtime" (timestamp, GMT), "swim_duration" (swim duration in seconds), "max_depth" (maximum recorded depth during a swim, in meters), "download_type" (if this record was transmitted over the ARGOS network (giving an unbiased sample of dives) or downloaded directly from a recovered collar (giving a complete record)).
3) Swimming_iceconc.txt is a tab-separated text file with 51301 records with the following columns: "id" (individual bear identifier), "dtime" (timestamp, GMT), "proportion_wet" (2 hour summary of proportion of time in water, centered on timestamp), "ice_concentration" (sea ice concentration in percent).
