Coasts

New maps from NIWA and the Deep South National Science Challenge show areas across Aotearoa New Zealand that could be inundated by extreme coastal flooding.

Researchers have discovered 26 species of roundworms that are completely new to science.

Researchers have developed New Zealand’s most comprehensive online atlas, providing an overview of nearly 600 marine species, to guide management and conservation of the country’s unique seafloor communities.

Our coastline is changing as sea levels rise. Lawrence Gullery looks at a five-year research programme designed to help communities with tough decisions ahead.

Based on the characteristics of individual organisms, Biological traits analysis is also a powerful way to measure ecosystem health and vulnerability to human activities.

A research project co-led by Blue Carbon Services and NIWA will aim to provide New Zealand’s first national estimate of natural kelp-carbon sequestration in the marine environment.

Traits are defined as the components of organisms that can be measured and have an effect on ecosystem functioning. Examples of traits include the behaviour, life history, morphology, and physiology characteristics

Beachgoers could be safer thanks to a new technology with the potential to give real-time updates of rip currents.

A study investigating the level of change needed to improve the state of Hawke’s Bay’s marine environment highlights the magnitude and frequency of interventions required for the seafloor ecosystem to recover.

NIWA is active in a broad range of eDNA topics and can provide expert advice on applications and expected outcomes. We welcome inquiries into our services and can assist with experimental design.

Prior to 15 January, Hunga Tonga-Hunga Ha'apai was a little-known undersea South Pacific volcano with a long name. Within 24 hours, it  was a global phenomenon – the site of the largest atmospheric explosion in almost 150 years. Jessica Rowley looks at why a remote Tongan volcano took the world by storm.
