The Tangaroa assisted in New Zealand’s largest ever deployment of seafloor earthquake recording instruments in a bid to learn more about the earthquake behaviour of the tectonic plates beneath the east coast of the North Island.

It’s been a year of discovery for NIWA scientists who now know more than they did 12 months ago – their top five discoveries for the year range from the bottom of the ocean to the top of the atmosphere.

This is a special series of stories put out to the media over the 2017/2018 summer.

NIWA research ship Tangaroa has been chartered by GNS Science to continue work in lowering Ocean Bottom Seismometers (OBS) onto the seafloor of the Hikurangi subduction zone.

Rapid warming of the ocean near Tasmania may provide a good indication of how the water around New Zealand will change as the planet warms, say NIWA scientists.

More than 50 “weather detectives” from 20 countries will be in Auckland next week to share their experiences saving snippets of meteorological history that will ultimately help scientists better understand the processes of climate variability and change.
