We are using modern techniques to map seafloor surrounding Kapiti Island, an area of significant cultural and environmental value to New Zealand.

Marine scientists have long recognized the potential of using remotely-sensed data, most often acquired using a sonar system, as a proxy of biophysical indicators.

Hundreds of amazing images have come back from NIWA’s NZ-AU Antarctic Ecosystems Voyage 2015 on RV Tangaroa.

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

This week’s critter is the colonial ascidian, or more commonly known as seasquirt, Leptoclinides marmoreus Brewin, 1956.

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.

Data collected continuously from this voyage will fill a critical knowledge gap, helping scientists to produce better global climate and oceanographic models to ultimately improve weather forecasting.

This research will investigate whether Antarctic silverfish eggs are spawned elsewhere or whether there is a mass migration of silverfish to their coastal spawning sites each winter.
