(a) Red polygon indicates the location and coverage of the study area in the Southeast Pacific. (b) Red points indicate fin whale sightings, (c) light-blue points indicate blue whale sightings, (d) purple points indicate sperm whale sightings, (e) green points indicate dusky dolphin sightings, and (f) yellow points indicate common dolphin sightings. Small white dots denote the midpoint for each on-effort track segment. Data layers (including maps) were created in R v. 4.0.2 (www.r-project.org) and ensembled in QGIS v. 3.8.0 (www.qgis.org) for final rendering. Maps were created using data on bedrock topography from the National Centers for Environmental Information (https://maps.ngdc.noaa.gov/viewers/grid-extract/index.html). Grid-cells with values above 0 were considered land coverage and assigned a uniform color.
