The research on the expedition contributed information toward improving our understanding of the population structure, abundance, trends, distribution and ecological role of whales in the Southern Ocean. Scientists used state-of-the-art non-lethal research techniques, focusing particularly on humpback, minke, blue and fin whales.

The researchers worked from onboard the Tangaroa, as well as from two smaller six-metre rigid inflatable boats.

From the Tangaroa, the scientists used a range of methods to collect and analyse information about the whales, including:

  • acoustic surveys
  • hydrographic surveys
  • collecting sitings data

A team of four or five researchers crewed each of the smaller rigid inflatable boats, which were deployed from the Tangaroa. From these smaller boats, a variety of methods were used to collect information about the whales, including:

  • biopsy sampling
  • satellite tagging
  • faeces collection
  • photo identification
