Now back on dry land, Voyage Leader Richard O'Driscoll reflects on the final days of RV Tangaroa's 2015 Antarctica expedition.

It has been another amazing week here on the Tangaroa. On Saturday we saw Antarctica which was an absolutely breath-taking experience that I’ll remember for the rest of my life!

Scientists from the Australian Antarctic Division explain the blue whale research they are leading onboard the New Zealand-Australia Antarctic Ecosystems Voyage 2015.

NIWA voyage leader Dr Richard O’Driscoll updates the Tangaroa’s encounter with the planet’s largest living beings – the Antarctic blue whales – and discovers what’s on their menu.

The first objective of the New Zealand- Australia Antarctic Ecosystems Voyage was successfully achieved with the completion of the research at the Balleny Islands.

This study will complement groundbreaking work undertaken in 2013 to determine the distribution of blue whales in the area and measure the characteristics of their habitats.

Scientists on a rugged mid-winter trip to the remote sub-Antarctic islands have confirmed a large contingent of endangered southern right whales are spending the colder months near Campbell Island.

Sightings of the whales, the world's largest animal, are rare and they remain one of the planet's most elusive creatures. They were intensively hunted during the whaling era in the Southern Hemisphere, dramatically reducing their numbers.
