KAIKOURA - AUV
This campaign brings together two Eurofleets+ Infrastructures, the RV Tangaroa and the autonomous underwater vehicle (AUV) from Sweden’s University of Gothenburg (UGOT).
Rob Christie, Manager Marine Resources, talks about the important relationship NIWA has with Eurofleets+
The primary objective is to re-map the Kaikōura Canyon and nearby targets using an Autonomous Underwater Vehicle (AUV RAN operated by the University of Gothenburg, Sweden).

Dr Yoann Ladroit, Whakaari TAN2007 Voyage
Marine Acoustician Dr Yoann Ladroit is leading research into using acoustics to find underwater gas bubble flares and then compare these to the chemical composition of water samples taken at the same locations.
Arne Pallentin, Whakaari TAN2007 Voyage
NIWA marine geologist Arne Pallentin is looking for telltale gas bubble 'flares"—using a multibeam echosounder—that indicate new volcanic activity in the Calypso Vent Field.
Joshu Mountjoy, Whakaari Voyage
Marine geologist - Dr Joshu Mountjoy - is mapping the seafloor landscape around Whakaari/White Island to understand how much sediment was dislodged in the eruption and where it has gone.
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.
Fisheries researchers combine technologies to collect more data at a lower cost.

Marlborough Sounds Seabed Survey

Hidden under the surface of the Marlborough Sounds is a fascinating underwater world of shipwrecks and seabed ridges the size of sand dunes in the Sahara Desert.

The findings of the most complex underwater coastal survey of the seafloor undertaken in New Zealand, including previously undiscovered natural features and sunken boats, are to be formally presented to the Marlborough community tomorrow.
Marlborough Sounds Survey

NIWA in association with Discovery Marine Limited, carried out the hydrographic survey on behalf of the Marlborough District Council and Land Information New Zealand.

NIWA's research vessels Ikatere and Rukuwai spent more than nine months on the water using the latest multibeam echo sounder technology to gather more than 5 billion data points and reveal exactly what lies beneath the surface.

The critically endangered Māui dolphin is getting a helping hand from scientists this month who are beginning a year-long research project to listen in on them.
