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.

  • Message in a bottle: Alexander Hayward, marine biogeochemist

    Sitting in the library of the R.V. Tangaroa, I’m contemplating the (almost) three weeks spent at sea. From the nauseating swell of the ferocious fifties to the mornings when I’ve woken to beautiful vistas of Antarctic mountains.

  • Message in a bottle: Dr Jenny Visser

    This is now my eighth voyage to Antarctica on Tangaroa. While my medical skills have been called on many occasions, my daily consultation rate at sea is low. So, I fill my time with other activities including getting involved in the science if needed.
