NIWA has updated and restarted a course using a riparian planning tool developed by one of its former chief scientists more than 20 years ago.

Estuaries are coastal waterbodies where freshwater mixes with seawater. Many estuaries in Aotearoa New Zealand have been impacted by pollutants and contaminants entering via freshwater.

From scallop beds to trawl nets, a little bit of data science can make a big difference. Melissa Bray explains.

The tiny ear bone of a fish holds a wealth of information. Gather enough and you get a snapshot of what’s happening beneath the waves. Stuart Mackay explains.

Jessica Rowley talks to three NIWA researchers trying to piece together what’s happening to the world’s largest ice shelf.

Climate change means more intense storm systems are on their way. Science can’t stop it raining, but it can help communities prepare for the worst and plan for the future.

Stacy Mohan looks at how the shockwaves from a remote Tongan island rippled through NIWA’s research community.

Mia Blyth catches up with a marine biologist hunting for ocean ghosts.

New findings from the record-breaking Tongan volcanic eruption are “surprising and unexpected."

A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought. This will be the final update of the Hotspot Watch for this season. Weekly Hotspot Watch updates will resume in the spring.
