Oceans

New information about landslides that occur on the seafloor off New Zealand’s east coast will help scientists better understand why and where they happen, and the types of threats they pose.

The New Zealand ship Janas has recently returned from a six-week winter research voyage to the Ross Sea where scientists made the first observations of developing Antarctic toothfish embryos.

Researchers are keeping a close eye on Owha, the leopard seal that has made Auckland Harbour her home, after she was seen bleeding from her face on Saturday morning.

Research shows how fish are being affected by microplastics.

New Zealand’s changing ocean environment has prompted the call to develop a system that will keep closer tabs on information from scientific monitoring buoys so the data they produce can be shared as widely as possible.

A chance discovery off the Gisborne coast five years ago is prompting a NIWA scientist to find out more about the link between a field of methane seeps bubbling out of the sea floor and submarine landslides.

A worm that feeds on bacteria and has no eyes is one of the standout stars of almost 600 unfamiliar and potentially new ocean species identified at NIWA in the past year.

Understanding how the Antarctic oceans work is vital to predicting the world’s future climate and the implications of climate change for humankind and the planet.

The on-going rise of atmospheric carbon dioxide (CO2) that is fuelling climate change is also driving significant changes in the waters off our coasts.
