Bathymetry

NIWA is leading a New Zealand partnership to map the South and West Pacific Ocean's seabed as part of a worldwide initiative to map the entire globe’s seafloor.

This dataset provides the most up-to-date bathymetry of one of the largest areas of deep-water seabed under national jurisdiction. The 250m resolution gridded bathymetric data set encompasses New Zealand's Exclusive Economic Zone and is available in multiple high-resolution file formats to suit a range of imagery and mapping needs.

NIWA scientists have mapped the whole of Lake Wānaka in incredible detail.  

NIWA are studying the ocean off Tairāwhiti and Hawke’s Bay to see how Cyclone Gabrielle has impacted the health of fisheries habitats and seabed ecosystems.

A New Zealand-led team has completed the fullest investigation to date into January’s eruption of the underwater Tongan volcano.
