Based at Bream Bay, Whangarei, Crispin Middleton is also an acclaimed underwater photographer and the recipient of numerous photography awards. His work regularly appears in New Zealand Geographic, dive magazines, scientific journals and conservation/ government documents.

The Ross Sea region is vital to the future of the Antarctic ecosystem.

NIWA researchers are out on the Hauraki Gulf this week to find out more about the nurseries of young snapper.

A chance find by a woman walking on a Northland beach is now helping scientists learn more about mako sharks.

Humans don't always make it easy on fish to get where they are going. New Zealand's first national set of Fish Passage Guidelines – co-developed by NIWA - is expected to help.

NIWA has developed a new method for spatially-explicit, quantitative, sustainability risk assessment of pelagic shark population.

Sharks are vulnerable to overfishing because of their low reproductive rates and often low growth rates. Most pelagic sharks fall near the middle of the shark productivity scale, and there is concern that catching too many of them could lead to population depletion. In New Zealand waters, mako sharks are the second most commonly caught shark species (after blue sharks) on tuna longlines.

Warrick Lyon is heading to the Marshall Islands to teach fisheries observers how to tag sharks.

One of the most challenging scientific underwater experiments ever attempted by NIWA is taking place this month on the Chatham Rise.

Think about a futuristic world where at night time, people use different kind of self-propelled vehicles to hover across cities, illuminating the skies with different colours and shapes, while transiting around them.

When NIWA fisheries scientist Richard O’Driscoll went to sea earlier this year, he and his team measured so many fish that laid end to end, they would have stretched for 31km.

At a laboratory just outside Whangarei, scientists are putting very young snapper through comprehensive physical testing - including a full medical check-up involving smell, hearing, vision, and even anxiety testing.
