A NIWA researcher has found the first evidence that female deep sea sharks store sperm as a strategy to preserve the species and possibly avoid aggressive mating encounters.
When scientists head south to Antarctica on board NIWA research vessel Tangaroa next month, they’ll be keeping a close eye out for an animal that is particularly good at staying out of sight.
Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.
NIWA ocean geologist Dr Joshu Mountjoy explains how the R.V. Tangaroa's multibeam system is used for bathymetric (seabed) mapping, and some of the benefits which come out of this mapping.
NIWA marine geologist John Mitchell gives a brief history of bathymetric (seabed) charting, and how it's been carried out over the last few hundred years. (01:18)
Tagging White Sharks off Stewart Island, NZ Scientists from DOC, NIWA, and the University of Auckland are building a unique picture of New Zealand's great white shark population.
NIWA scientists have worked for many years in Antarctica. These photographs illustrate some of our work in this amazing and scientifically significant place.
Day 13 of the Ross Sea Life in a Changing Climate (ReLiCC) 2021 voyage on RV Tangaroa finds us close to Cape Adare on the tip of the Antarctic continent. We’ve had a busy and icy week.

Storm-tide red alerts are the highest high tide (also known as king tides) dates that Emergency Managers and Coastal Hazard Managers should write in their diaries and keep an eye on adverse weather (low barometric pressure, onshore winds), river levels and sea conditions (waves and swell).
Small orange flecks spotted floating around in a respiration chamber at a NIWA laboratory have led to a discovery about the spawning habits of a deep-sea stony coral in New Zealand waters.
A six-metre long orange underwater robot is flying through the Kaikōura Canyon for the next month collecting information on how the canyon has changed since the 2016 earthquake.
People along the Kapiti and Wanganui coast may spot NIWA’s research vessel Kaharoa operating close to shore in the next few weeks as scientists carry out a survey of snapper, tarakihi, red gurnard and John Dory.
After a decade-long effort, NIWA’s latest Biodiversity Memoir has just rolled off the presses. Written by marine biologist Kareen Schnabel, the 350-page treatise presents everything we currently know about the different kinds of squat lobster living in New Zealand’s waters.
At the bottom of the Southern Ocean, near Cape Adare in East Antarctica, lies an undersea ridge which until this month was only known by its co-ordinates: -71.2132 latitude, 172.1649 longitude.
Albatrosses may be masters of the skies, but they are surprisingly vulnerable on the water. Campbell Gardiner talks to two scientists working to keep these magnificent seabirds airborne.
New measurements from the ocean under the centre of the Ross Ice Shelf have significantly improved our understanding of the complex processes that drive melting in Antarctica.
