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.
One of the most challenging scientific underwater experiments ever attempted by NIWA is taking place this month on the Chatham Rise.
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.
A team of international researchers leaves Wellington this weekend to explore the bottom of the Kermadec Trench – one of the deepest places in the ocean.

Our work

Seagrass beds form an important undersea habitat for small fish, seahorses and shellfish in New Zealand.
New Zealand's Kaikoura Canyon is a 'biodiversity hotspot', containing far more life than seen before at such depths.
This research project investigated whether the mechanisms for periphyton removal in rivers relate more directly to hydraulic and geomorphic conditions than flow metrics.

The R V Tangaroa headed to the Chatham Rise from 9 May to 7 June 2018 to measure and monitor the effects of seabed disturbance on sealife.

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.

It is well known that earthquakes can trigger tsunami but they can also be caused by landslides – with devastating effects.
NIWA vessel RV Tangaroa visted Kaikōura in September 2017 to investigate the impacts of the earthquake in the coastal zone, which includes effects on rocky reef habitats and communities, pāua fishery and Hector’s dolphins.

Pollen from New Zealand pine forests has been shown to travel more than 1500km through wind and ocean currents, and sink thousands of metres into the ocean to reach some of the world’s deepest ecosystems.

Huge mudslides from November’s earthquakes have wiped out all organisms living in the seabed of the Kaikōura Canyon.

This research project investigated whether the mechanisms for periphyton removal in rivers relate more directly to hydraulic and geomorphic conditions than flow metrics.
