The RV Tangaroa is assisting 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.
This voyage is the first of a series of expeditions exploring selected trenches of the Pacific Ocean, starting with the Kermadec trench. It will investigate carbon and nutrient cycling by microbial communities in trenches exposed to different rates of organic carbon supply.

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.
The voyage to the Kermadec region is a collaborative expedition between NIWA, Auckland Museum, Kelly Tarlton’s, Department of Conservation, Auckland and Massey Universities, The PEW Charitable Trusts and Te Papa.
NIWA’s research vessel Kaharoa has been on a three-week voyage to deploy the first Deep Argo floats to collect data on ocean heat gain at depths of about 5700m. Deployed across the abyssal plains of the South West Pacific the floats are one tool for unlocking key global climate change information in our oceans.
The six-week New Zealand-Antarctic Ecosystem Voyage saw RV Tangaroa travel through the Southern Ocean to the Ross Sea to conduct a range of scientific fieldwork. The voyage was a collaboration between Antarctica New Zealand, NIWA and the Australian Antarctic Division.
Funded by NIWA and the Department of Conservation (DOC) this month-long voyage investigated whether southern right whales continue to spend their winters at Campbell Island, how many there were, where they came from and what they ate.
This east coast voyage aboard the RV Tangaroa found direct evidence of widespread gas in the sediment and ocean, and indications of large areas of methane hydrate (an ice-like frozen methane) below the seafloor.
The RV Tangaroa has been on a five-week voyage to the Louisville Seamount Chain in the South Pacific. It will give scientists a better understanding about marine ecosystems vulnerable to commercial fishing in the region.
During a week-long voyage aboard the RV Ikatere, NIWA scientists provide new insights into the significant tsunami risk from an undersea landslide in the Kaikoura Submarine Canyon just off the South Island's east coast.
With a focus on climate change, territorial aspirations of Antarctica, protecting biodiversity, over-fishing, tourism, and mineral exploration, the Our Far South voyage to Antarctica created a unique opportunity to raise public awareness about research happening in the southern ocean and the Antarctic area.
Utilising the RV Tangaroa's benthic grab capabilities, an international team from the United States and New Zealand have observed, for the first time, the bizarre deep-sea communities living around methane seeps off New Zealand’s east coast.
Onboard the RV Tangaroa, NIWA scientists revitalised the growth of microscopic plants to show how phytoplankton may be a key element in absorbing carbon dioxide out of the atmosphere and to better understand the role of the Southern Ocean in climate change.
