Advances in thermal physiology of diving marine mammals: The dual role of peripheral perfusion

The files contain data from one juvenile northern elephant seal (male, 172 kg) whose trip at-sea was ~7 days. Two sections of data are provided with the variables listed below that were used to create the figures in Favilla et al. 2021 Temperature. All variables listed were sampled at 1 Hz. Data-0502204000_0503083000.csv & Data-0508013000_0509013000.csv Columns and relevant descriptions: DateTime: GMT date and time Depth: meters WaterTemp: degrees Celsius, temperatures during surface interval (where the tag may have been out of the water) was corrected by replacing surface ‘air’ values with average value within top 2 meters HeatFlux: W m2, corrected for additional thermal resistance from sensor and attachment mechanism and manufacturer’s calibration constant, measured at flank BlubberDeep: degrees Celsius, thermistor placed near muscleblubber interface BlubberMid: degrees Celsius, thermistor placed near the middle of the blubber layer BlubberShallow: degrees Celsius, thermistor placed subcutaneously in blubber layer DiveStat-No530_601.csv Columns and relevant descriptions: DiveNumber StartTime: GMT date and time of dive start MaxDepth: meters DiveDuration: H:M:S, time elapsed between beginning of dive descent and end of ascent SurfaceDuration: H:M:S, time elapsed between end of dive ascent and beginning of subsequent dive SolarEl: degrees, solar elevation determined using geolocation and date and time TimeOfDay: defined by SolarEl, where elevation > 0° is ‘Day’ and elevation ≤ 0° is ‘Night’
