Tangaroa Marine Environment and Ecosystem Voyage 2018

RV Tangaroa carried out a six-week voyage to Antarctica and the Southern Ocean between 9 February and 21 March 2018.

RV Tangaroa carried out a six-week voyage to Antarctica and the Southern Ocean between 9 February and 21 March 2018 with scientists from NIWA and the University of Auckland.

Scientists did a range of surveys to better understand the processes governing this environment and its relevance to New Zealand. These included oceanographic observations, atmospheric observations, whale and benthic habitat studies, along with studies of plankton communities. The whale studies were carried out by the University of Auckland.
