MaREI researcher Ailbhe Kavanagh has begun her 7 week Antarctic blue whale and krill voyage. This is the most comprehensive scientific voyage ever undertaken to study the largest creature on Earth and its food source.

A team of 28 international scientists hope to get an intimate glimpse into the daily lives of Antarctic blue whales and Antarctic krill, on board the CSIRO Marine National Facility research vessel Investigator as part of the Australian Antarctic Program.
Using underwater listening devices to locate and track the whales, the voyage will undertake a number of ‘firsts’ in scientific research

The multibeam echosounders of the RV Investigator will develop the first detailed three-dimensional models of the size, shape, and density of krill swarms.

Also for the first time, drones will be flown over Antarctic blue whales to photograph, measure and identify individuals, and attempt to collect samples of both the blow when a whale exhales and any faeces in the surface water.
