The survey was designed for a two independent visual observer teams approach with Distance sampling to estimate the detection probabilities for marine mammal sightings; however, the survey was conducted with only one team between 14 January and 5 February. Occurrence GBIF Dataset Type Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_type.xml Observation GBIF Dataset Subtype Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_subtype.xml Marine Biology Visual sighting Marine Animal Survey Marine mammals Visual Sighting Vessel N/A Provider's survey code is GU1801. Perpendicular distance to the animal is not publicly available. The dataset is accompanied by transect (effort) data which is provided as a separate file. Sightings included were detected by the flying bridge only or by both the flying bridge and bridge wing teams.
