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.

The Southern Ocean Freshwater Input from Antarctica (SOFIA) Initiative aims to improve our understanding of the simulated response to Antarctic freshwater input, and in particular the model uncertainty. The initiative has developed an experimental protocol and is engaging with modelling groups from around the world to run this common set of experiments using a variety of coupled climate and ocean-only models. Data from this international multi-model ensemble is openly shared for analysis, and is being synthesized into a series of publications by SOFIA participants.
