A major collaborative effort involving French and New Zealand researchers will be delving in mud beneath the seafloor this month, looking for clues about past and future climate change and its various effects on the seafloor.

A 28-metre research vessel from NIWA will spend the next four and half months deploying ocean-profiling Argo floats across the Pacific.

Scientists from NIWA are diving in Waitemata Harbour to establish precisely how far an invasive sea squirt, known as the clubbed tunicate (or Styela clava), has spread.

Large areas of the ocean, such as the north Tasman and Mediterranean Seas, are low in nutrients with only limited growth of phytoplankton, the microscopic plant cells at the base of the food chain.

A New Zealand woman is leading a project that will bring together several hundred scientists from over 30 countries for the next 10 years.

NIWA’s smaller research vessel, Kaharoa, leaves Wellington tomorrow (Thursday 21 April) on a 2-month voyage to deploy high-tech 'Argo' floats all the way to Hawaii and back.

Already, the crew of Kaharoa have deployed more Argo floats (141 so far) than any other vessel in the world. By the end of this trip, they will have deployed over 200 floats and clocked up over 40,000 nautical miles on Argo missions. That is almost the equivalent of sailing to the UK and back twice. (A round trip to the UK is approximately 24,000 nautical miles.)

New Zealand and American scientists have joined forces to explore some of the world’s most active undersea volcanoes along the Kermadec Arc, northeast of the Bay of Plenty.

In an uncommon event, icebergs have been spotted in New Zealand waters.

Sustainable development of the coasts & oceans will be the focus of a new National Centre formed by the National Institute for Water & Atmospheric Research (NIWA).

The Centre will be launched today (24 November) on board NIWA’s deepwater research vessel, Tangaroa.

“Science has much to offer in helping guide exploration, management, and protection of coastal and marine resources,” says NIWA’s chief executive, Dr Rick Pridmore.

Go to the east coast of the North Island, and the climate will be about 1.2 degrees Celsius warmer, on average, than at the same latitude on the west coast.

The reason: subtropical water brought across the Tasman Sea on an ocean current known as the Tasman Front. It’s an extension of the East Australian Current – the playground of surfing sea turtles in the movie, Finding Nemo.

The NIWA vessel, Kaharoa, is setting sail on a 90-day voyage to deploy high-tech floats between New Zealand and Peru.

Kaharoa will carry 84 floats, which is the largest number ever deployed in a single voyage. Each float is worth about $20,000, making the total worth over $1.6 million.

The floats can help scientists measure global warming, predict the strength of tropical cyclones, and even get a better fix on the path of toxic algal blooms.

Another toxic algae is added to the list of harmful marine algae in the waters around New Zealand.

NIWA’s research vessel Tangaroa leaves Wellington tomorrow tonight for the Southern Ocean on one of New Zealand’s largest oceanographic research surveys. The 30 scientists on board, from 17 organisations in 6 countries, will study how the ocean controls climate through the uptake and release of crucial greenhouse gases such as carbon dioxide.

A New Zealand research vessel will set sail from Wellington Harbour this Sunday bound for Chile as part of a major international project to understand and predict the phenomena influencing the world’s climate.

On 27 January 2004 a team of scientists set out from Wellington on board NIWA’s research vessel Tangaroa bound for the Ross Sea in Antarctica.

Two rare New Zealand seaweeds have been discovered in Northland, and they could have exciting commercial applications for the pharmaceutical and biotechnology industries.

Scientists thought they had seen the last of a drifter buoy lost during an experiment in the Southern Ocean in 1999. But to their amazement, the buoy has turned up halfway around the world in the Falkland Islands – albeit looking a little worse for wear.

The NIWA research vessel Tangaroa, which rescued British rower Jim Shekhdar from the waters of the Southern Ocean earlier this week, had just finished mapping the shipping lanes of Foveaux Strait.

An underwater video camera on wheels is the latest weapon in the war against the introduction of exotic marine species into New Zealand waters.

NIWA and Te Papa have signed a new agreement to help improve research for management of New Zealand’s aquatic biodiversity and biosecurity.
