Steminists working remotely

Rangitāhua expedition series

Recently returned from the Rangitāhua Islands, the multidisciplinary Expedition Kaharoa held a record number of female crew members. From voyage leader, small boat skippers and vessel officer, to analysing complex data, the 15 women onboard had diverse roles and responsibilities all contributing to the expedition's success.

The Tohoraha of Rangitāhua

Commercial whaling has had a devastating impact on the Oceania whale population, with fewer than 5% remaining. Now, the tohoraha (humpback whales) are returning to Rangitāhua, and we're thrilled to see more and more with each voyage to the Kermadec region.

Illuminating the depths

From the belly of the Tangaroa research vessel, a world is revealed. A science expedition to New Zealand’s most remote islands has exposed never before seen underwater forests and areas of the sea floor.

Seaweeds and the importance of home

Rangitāhua expedition series

Many things in our ocean can be called ‘sea-weeds’, but very rarely are they noxious or undesirable. In fact the abundance of seaweeds provides crucial habitat for many animals. Young turtles, fish, crabs, sharks and more, use seaweed environments as nurseries, while species of seahorses, fish, and shrimp will always call seaweeds home.

Monitoring beyond remote locations

How much more remote can you get than the Rangitāhua Islands? 1,000 meters to be precise. That's how deep some of the science equipment plunged as part of last year’s Te Mana o Rangitāhua expedition. Researchers Joe O’Callaghan, Sarah Searson and Arnaud Valcarcel used Conductivity, Temperature, and Depth (CTD) monitors to understand the raw components of seas surrounding Rangitāhua.
