Original provider: Conor Ryan Dataset credits: Conor Ryan Abstract: Sightings of humpback whales and rough-toothed dolphins (all cetaceans encountered on-track) and the associated search effort (from a 5m RIB at 7 - 10 knots). Note that some of the effort associated with the outlying sightings are missing, but can be asssumed to be the shortest route to Sal-Rei.
