Brief description

During the 2019 ENRICH Voyage of the CSIRO vessel, RV Investigator, a digital photogrammetric video tracking system was used to collect precise surfacing locations during encounters with mainly Antarctic blue whales, but also some fin whales. The photogrammetric video tracking system is a modern digital video version based on the same operating principle as the that described by Leaper and Gordon 2001, and enables determination of the range and bearing to tracked objects relative to the ship.

Video tracking was conducted on 24 occasions for a total of 18 hours. Focal follows were aborted when it was no longer possible to follow the focal animal due to ice or when the presence of other animals meant it was no longer possible to be sure which was the focal animal.

Progress Code: completed
Statement: Data are good quality, with no known issues or problems.

Notes

Purpose
Photogrammetric video tracking was conducted in order to obtain data on baseline surface behaviour and fine-scale movements of Antarctic blue whales, and to enable investigation of relationships among vocal activity, behaviour, and movement.
