Data from: Fine-scale movement responses of free-ranging harbour porpoises to capture, tagging, and short-term noise pulses from a single airgun

Exposed porpoise GPS dataThis is the full dataset collected by GPS tags fitted on four harbor porpoise individuals. Large positional errors were removed as described in the article. The data also contains the calculated horizontal movement parameters and distance variables to produce figure 1 in the main article and the figures in the Supplementary material. The data contains 10 variables: “id” gives the name of the harbor porpoise individual “datetime” gives the date and time of the GPS location columns “x” and “y” are the coordinates of the GPS location in the projection CRS("+proj=utm +zone=32 +ellps=intl +towgs84=-87,-98,-121,0,0,0,0 +units=m +no_defs") “steplength” is the Euclidian distance (m) between GPS locations “speed” is the speed (m/sec) between GPS locations “turing_angle” is the turning angle (degrees) between GPS locations “hour_since_release” is the time (hours) since the individual was released into the water after GPS tagging “dist_to_exposure_site” is the Euclidian distance (m) of the individual porpoise relative to the airgun exposure site “dist_to_release_site” is the Euclidian distance (m) of the individual porpoise relative to the GPS tagging and release siteraw_data_horizontal_movements_160503.txtExposed porpoise dive dataThis is the full dataset collected by dive-loggers fitted on four harbor porpoise individuals. Impossible values were removed as described in the article. It is the underlying data used to produce figures in the Supplementary material and contains 6 variables: “id” gives the name of the harbor porpoise individual “datetime” gives the date and time of the start of each dive “dive_duration” gives the difference in time (sec) between the start and end of each dive “max_depth” provides the maximum depth (m) reached during each dive “wiggliness” provides the sum of absolute depth differences (m) while at the bottom of each dive; measure of amount of “wiggling” while at bottom “post_dive_duration” provides the time (sec) spent at the surface after each diveraw_data_vertical_movements_160503.txtresidual_data_horizontal_movementsContains the residuals of the GAM analyses on the horizontal movement data, which was used in the piecewise regression analyses. It is the underlying data used to produce figure 3 in the main article and contains 5 variables: “id” gives the name of the harbor porpoise individual “hour_since_release” is the time (hours) since the individual was released into the water after GPS tagging “residuals_steplength” are the residuals of the Euclidian distance (m) between GPS locations “residuals_speed” are the residuals of the speed (m/sec) between GPS locations “residuals_turing_angle” are the residuals of the turning angle (degrees) between GPS locationsresidual_data_vertical_movementsContains the residuals of the GAM analyses on the vertical movement data, which was used in the piecewise regression analyses. It is the underlying data used to produce figure 4 in the main article and contains 6 variables: “id” gives the name of the harbor porpoise individual “hour_since_release” is the time (hours) since the individual was released into the water after GPS tagging “dive_duration” are the residuals of the difference in time (sec) between the start and end of each dive “max_depth” are the residuals of the maximum depth (m) reached during each dive “wiggliness” are the residuals of the sum of absolute depth differences (m) while at the bottom of each dive “post_dive_duration” are the residuals of the time (sec) spent at the surface after each diveR-codeThe file contains the R-code for the piecewise linear regression analyses and model selection used to assess capture/tagging and airgun noise-induced movement responses in harbour porpoises
