Marine Invertebrates

Latest news

NIWA’s Marine Invertebrate Collection has welcomed two extremely rare octopus that have only just been provisionally identified.

Pollen from New Zealand pine forests has been shown to travel more than 1500km through wind and ocean currents, and sink thousands of metres into the ocean to reach some of the world’s deepest ecosystems.

A voyage to the Kermadec Islands has resulted in the discovery of many species either new to science or not previously found in the area.
A new fully illustrated electronic identification guide, Bountiful Bryozoans, has just been released to help people identify this group of marine creatures in the wild.

Our work

NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea.

Ocean acidification - what is it?

The on-going rise of carbon dioxide (CO2) in the atmosphere is not only changing our climate—it is also changing our oceans. Take a look at the work of the NIWA-led CARIM project into what these changes may mean for the delicate balance of marine life.

The NIWA Invertebrate Collection (NIC) holds specimens from almost all invertebrate phyla. This is a result of about half a century of marine taxonomic and biodiversity research in the New Zealand region, the South West Pacific and the Ross Sea, Antarctica.

The Ross Sea Region Research and Monitoring Programme (Ross-RAMP) is a five-year research programme funded by the Ministry of Business, Innovation and Employment (MBIE) and run by NIWA to evaluate the effectiveness of the Ross Sea Marine Protected Area.
During the voyage, we collected planktonic protist cells for which DNA will be sequenced for taxonomic identification, but also to understand their physiology through the daily diurnal vertical migration (diel) cycle.
From 8 Jan - 27 Feb 2019 RV Tangaroa is undertaking a six-week research voyage to Antarctica and the Southern Ocean. On board scientists, supported by 19 crew members, will be studying ocean, atmosphere and ecosystem processes with the focus on establishing monitoring programmes for the newly created Ross Sea Region Marine Protected Area (MPA).

26 October 2018. NIWA Blake Ambassadors, Lana Young and Siobhan O'Connor and SalpPOOP voyage leader Dr Moira Decima check out sampled salps from different depths.

Students at Leigh School have been working with marine scientists and the 'Year of the Salps' project partners to learn how to count sea salps, understand salp life cycle phases and the importance of salps in marine ecosystems and their carbon-cycling effects on climate change.
