During the TAN2007 voyage NIWA scientists headed to the waters around Whakaari/White Island in the Bay of Plenty to survey changes to the seafloor since the volcanic eruption in December 2019. They surveyed the chemical composition of gases released by the hydrothermal vents on what is known as the Calypso vent field in the Bay of Plenty.
Heading to the Campbell Plateau south of New Zealand, 25 scientists and crew onboard R.V. Tangaroa will carry out a deep sea camera survey of the seabed to better understand the biodiversity of seabed habitats in commercial fishing areas.
RV Tangaroa undertook a six-week research voyage to Antarctica and the Southern Ocean to study the ocean, atmosphere and ecosystem processes with the focus on establishing monitoring programmes for the newly created Ross Sea Region Marine Protected Area (MPA). Link to the voyage report.
Understanding and modelling the effects of climate variability on ecosystem function in the Sub-Antarctic region, including effects on protected species and on ecologically and economically important
Geophysical data and seafloor samples were collected in several study areas off the Wairarapa coast and off the coast of north-eastern South Island. These samples give new insight into seafloor composition above gas hydrate accumulations as well as the reservoir sediments within which gas hydrates form.
Deployment and recovery of Ocean Bottom Seismometers occurred on three separate cruises of the RV Tangaroa between September 2017 and April 2018 (ORCSS 1 to 3), as part of a multi-national seismic experiment on the Hikurangi subduction margin off the east coast of the North Island.
HOBITSS V was a 12-day (6–18 October 2018) voyage onboard R/V Tangaroa to undertake seafloor geodetic and seismic instrument deployments, recoveries, and surveys offshore the Gisborne, Mahia, and Wairarapa coasts.
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.
The RV Tangaroa headed out to the Chatham Rise on 23 October 2018 for a month long voyage that with a focus on the special role sea salps play in carbon cycling, and where they fit in marine food webs off the New Zealand coast.
The sub-Antarctic ocean around Campbell Plateau is complex with three distinct oceanographic regions comprising of warm and salty subtropical water, cooler and fresher sub-Antarctic water and colder and fresher circumpolar sub-Antarctic water.
In passive continental margins, topographicallydriven meteoric groundwater is only one of a range of drivers of offshore groundwater flow. Other drivers include seawater recirculation, sediment loading, geothermal convection, and diagenesis.
This survey was designed to acquire quantitative data about benthic habitats and fauna across Chatham Rise, using a towed camera system with high-definition digital video and still image cameras and a multicorer.
The goals of this Earth science project were: 1) to obtain constraints on the deep structure of the Hikurangi margin, with an emphasis on Raukumara peninsula in the north, and 2) to record seismicity over several months.
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.
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.
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.
The main output of this voyage is providing data and fundamental base maps for future regional prospectivity surveys, tectonic plate reconstructions, and general understanding of the architecture of the Kermadec backarc.
The primary objective of this voyage was to recover sedimentary cores from the continental slope of Hikurangi Trough expected to deliver records of past earthquakes associated of past earthquakes associated with the Hikurangi subduction zone.
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.
This survey was undertaken in the Great South Basin with the intention of completing a multi-beam echo sounder survey across the head of the Bounty Trough and Otago Canyons. This will act as a baseline dataset for future voyages.
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.
Scientists set sail on NIWA's research vessel Kaharoa this week to film and explore many aspects of life in deep-sea habitats, and capture fish that are new to science, in the Kermadec Trench, northeast of New Zealand.
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.
