Students at Leigh School have been working with marine scientists and the 'Year of the Salps' project partners to learn how to count sea salps, understand salp life cycle phases and the importance of salps in marine ecosystems and their carbon-cycling effects on climate change.

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

Research conducted after the 2016, 7.8 magnitude Kaikōura earthquake has provided scientists with an extremely rare opportunity to understand the processes that shape submarine canyons.

As part of a Pacific-wide study, NIWA is measuring the survival rate of sharks returned to the sea by commercial tuna fishers.

A NIWA scientist who spent years poring over handwritten scientific notes stored in about 50 large wooden drawers, has seen the fruits of her labour now being used in ways she never imagined.

The new science season at Antarctica is just a few days away from opening and NIWA researchers are busy packing containers and shipping them to the ice where they will be reunited with them in the coming months.

Identifying dolphins using photos of the unique pigment patterns on their fins can be used to help in the management of a species, says a NIWA scientist.

Wellington’s whale may be a sign they are returning to their historical habitat, says NIWA.

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.
