RV Tangaroa undertook a 45-day voyage to the Southern Ocean and Ross Sea (10 January - 16 February, 2021)

Scientists carried out nine separate objectives to better understand the processes governing this region and the role of the Marine Protected Area (established in December 2017) in protecting this environment. These included surveys of fish species and seabed habitats, ecosystem studies of plankton, oceanographic and atmospheric measurements to improve understanding of climate-related processes, and making observations of whales.

  • Voyage update 4 from Evan Solly, Ice Pilot

    The clear sky and exceptional visibility made our approach to Woods Bay very memorable with Mount Melbourne dead ahead and Mount Murchison on our starboard beam.
  • Message in a bottle: Sarah Seabrook

    It is interesting to watch all of the pieces of our science story come together with each day’s water sampling and our long term experiments.
  • Message in a bottle: Stuart Mackay, Digital Producer

    Antarctica is an incredibly pristine place; we are here to do good science and leave no trace. So, you can imagine my horror as I watched my camera start to float away from the boat.
