Plankton

Long-term protection of Otago’s coastal habitats took a step closer to reality after more than 100 marine Significant Ecological Areas were identified.

As New Zealanders search for the summer sun, 38 researchers and crew will board RV Tangaroa tomorrow for a six-week science voyage deep into the waters of Antarctica.

Studying the mesopelagic in the Ross sea

Follow a group of NIWA scientists investigating various aspects of plankton which are the base of the Antarctic oceans food web.

It is interesting to watch all of the pieces of our science story come together with each day’s water sampling and our long term experiments.

NIWA’s flagship research vessel Tangaroa leaves soon on a six-week voyage to Antarctica, making it one of the few full scientific expeditions to the continent since the global outbreak of COVID-19.

The on-going rise of carbon dioxide (CO2) in the atmosphere is not only changing our climate—it is also changing our oceans. 

After travelling almost 12,000km in the past six weeks, a group of scientists returns to Wellington at the weekend with new knowledge about life in the Ross Sea of Antarctica.

Phytoplankton: tiny cells with a big job

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.
