A dataset containing a sample of processed flapper skate (Dipturus intermedius) detection time series. Data are arranged by individual_id, timestamp and then receiver_id (see below).
dat_acousticsA dataframe with 39,242 observations and 9 variables:
A unique identifier of the individual that was detected (see dat_ids).
The acoustic transmitter that was detected (see dat_ids).
An integer individual-specific cumulative detection index.
A POSIXct object which defines the time of each observation.
A unique identifier of the receiver at which the individual was detected (see dat_moorings).
The receiver at which the individual was detected (see dat_moorings).
The longitude of the receiver at which the individual was detected (see dat_moorings).
The latitude of the receiver at which the individual was detected (see dat_moorings).
The depth of the receiver at which the individual was detected (see dat_moorings).
Data were collected by, and belong to, Marine Scotland Science and NatureScot. Data were processed by Edward Lavender. If you wish to use these data, please contact Marine Scotland Science and NatureScot for further information.
Time stamps are expressed to the nearest two minutes. `Duplicate' detections (of the same individual at the same receiver in the same time step) are excluded. This supports the implementation of the acoustic-container (AC) and acoustic-container depth-contour (ACDC) algorithms (see ac and acdc).
