Flash and grab: deep-diving southern elephant seals trigger anti-predator flashes in bioluminescent prey (dataset)

Data set in support of the paper: ‘Flash and grab: deep-diving southern elephant seals trigger anti-predator flashes in bioluminescent prey’ by Pauline Goulet, Christophe Guinet, Claudio Campagna, Julieta Campagna, Peter Lloyd Tyack and Mark Johnson published in J Exp Biol (2020). Data were obtained from a biologging device containing a fast-sampling light sensor together with location and movement sensors deployed on female southern elephant seals at Kerguelen Islands and Peninsula Valdes (Argentina). The data subset comprises 5 days from each animal and includes time series for depth, jerk and light, sampled at 50Hz. The data for each animal is in a NetCdf format file containing the variables: info (deployment ID, seal ID, deployment start date, data provider, study species, deployment location), J (root mean square of the vector magnitude of the rate of change in the 3-axis acceleration along with information on sampling rate, measurement unit, cropping factor), P (calibrated and offset-corrected pressure data along with information on sampling rate, measurement unit, cropping factor) and LL (corrected light data along with information on sampling rate, measurement unit, cropping factor).
