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.
