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.

Find out about the role of toothfish in the ecosystem and the potential effects of fishing.

Now back on dry land, Voyage Leader Richard O'Driscoll reflects on the final days of RV Tangaroa's 2015 Antarctica expedition.

A recent expedition to one of the deepest places on Earth has discovered one of the most enigmatic creatures in the deep sea: the 'supergiant' amphipod.

Welcome to NIWA's third Alumni Update – an e-newsletter for past NIWA employees.

Welcome to the latest edition of Coasts Update. Here we bring you news of some of NIWA's latest research on aspects of coastal ecology, and the possible impacts of climate change on one of our coastal communities.

New Zealand's Kaikoura Canyon is a 'biodiversity hotspot', containing far more life than seen before at such depths.

The return of the upgraded RV Tangaroa represents a huge advancement for New Zealand science and exploration

Welcome to NIWA's second Alumni Update – an e-newsletter for past NIWA employees.

In the past half century, mangroves have increased in extent in estuaries and tidal creeks throughout the upper half of the North Island.

Estuarine restoration research is relatively new in New Zealand and has been largely instigated by community groups that have become increasingly concerned with the decline of plant and animal species.

Two New Zealand research organisations will work closely with one of the world’s leading ocean research and engineering organisations to accelerate research and exploration in a wide range of oceanographic topics in the southwest Pacific region.
