Researchers from NIWA will be surveying marine habitats in Kaikoura for foreign organisms next week (14–20 May).

A trans-Tasman team of scientists is setting out to discover just how much water flows south of New Zealand as part of the world’s largest current, the Antarctic Circumpolar Current.

NIWA has produced a public information leaflet about icebergs, with help from Vincent Aviation.

An international team led by scientists 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.

As a flotilla of modern-day icebergs heads away from New Zealand, scientists from NIWA have identified what appear to be ancient iceberg scours on the seabed off New Zealand’s east coast.

The flotilla of icebergs currently off the South Island were probably once part of a much larger iceberg from the Ronne Ice Shelf, on the other side of Antarctica from New Zealand.

Researchers from NIWA will be surveying Kaipara Harbour and marinas for foreign marine organisms next week.

Researchers from NIWA have recently surveyed ports at Milford Sound (Fiordland) and Taharoa Ironsands Terminal (Waikato) for foreign marine organisms.

It's an epic journey for a small bird. A team of scientists from New Zealand, the US, and France has discovered that sooty shearwaters (known to Kiwis as muttonbirds or titi) make a 64 000 km round trip each year, chasing summer across the Pacific.

Scientists from NIWA have made the first measurements of photosynthesis in the icy gloom of an Antarctic lake floor.

After four and a half months, and 23,186 nautical miles, a New Zealand research vessel is finally coming home.

New Zealand’s seagrass meadows are important, but threatened, coastal habitats that we still know little about. Scientists from NIWA are undertaking a nationwide survey of these vibrant underwater meadows, to find out more about the life they support and their wider role in the marine ecosystem.

An international team of marine scientists returns to the Chatham Islands next week hoping to fit satellite tags on up to 13 great white sharks. The tags will allow the scientists to track the sharks' movements for up to nine months.

A NIWA scientist has used sophisticated sonar technology to reveal a ghost-like image of the Mikhail Lermontov lying in its watery grave in the Marlborough Sounds.

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.)
