Scientists have taken a step closer to predicting marine heatwaves with new NIWA-led research finding a link between their formation and the length of time sea temperatures are warmer than normal.
A new scientific assessment of Hector’s and Māui dolphins has led to a revised understanding of their biology, their distribution and their main threats.
For more than a year a frozen slab of leopard seal poo sat in a NIWA freezer. The poo, known scientifically as scat and about the size of two bread rolls, is as good as gold for leopard seal researchers.
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 findings of the most complex underwater coastal survey of the seafloor undertaken in New Zealand, including previously undiscovered natural features and sunken boats, are to be formally presented to the Marlborough community tomorrow.
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.
One of the world's leading scientific publishers has named a paper cowritten by a NIWA scientist as one of 250 groundbreaking findings that could "help change the world".
New Zealand’s contribution to an ambitious international project aiming to generate a definitive map of the entire ocean floor in less than 12 years, is being launched in Wellington tomorrow.
Two yet-to-be identified species of beaked whales have been detected in the Cook Strait region. Identifying which species they are is important for understanding the status of marine mammal populations in New Zealand waters.
Scientists have launched a worldwide crowdsourcing competition aimed at finding novel ideas to tackle invasive marine pests, with a cash prize of $US10,000 on offer.
The 2016 Kaikōura Earthquake has shown that more than 100 million dumptrucks of mud and sand flow through the Kaikōura Canyon every 140 years, scientists say.
A two-week expedition to tag blue whales in New Zealand waters for the first time, almost came up empty due to warmer sea temperatures causing the animals to change their behaviour.
Every year NIWA carries out numerous marine surveillance missions, surveys at ports and harbours around the country. Their divers are looking for the pests that have hitched a ride to New Zealand waters and are capable of destroying our unique ecosystems and shellfish industry.
Scientists exploring the Kermadec Trench believe they have retrieved the deepest ever sediment sample from the bottom of the ocean using a wire-deployed corer.
