Mangroves on the atoll of Ouvéa are struggling with the changing climate

Researchers created national sea-level risk profiles for populations, buildings, croplands & infrastructure under present & future climate scenarios.

NIWA works collaboratively with our Pacific partners to support the sustainable management and resilience of the Pacific’s natural resources, environments and communities.

The Tongan deepwater demersal line fishery is a valuable source of income, livelihood, and social well-being for the people of Tonga. The fishery has a history of boom-and-bust cycles with fluctuating catches and poor economic returns.

The 2022 Tonga volcanic eruption triggered the fastest underwater flow ever recorded.

Mangrove systems on oceanic atolls may lose the race to keep pace with sea-level rise.

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.

A New Zealand-led team has completed the fullest investigation to date into January’s eruption of the underwater Tongan volcano.

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

NIWA and The Nippon Foundation are undertaking a mission to discover the undersea impacts of the recent Tongan volcanic eruption.

NIWA scientists and Toitū Te Whenua Land Information New Zealand (LINZ) have used satellite technology to chart the Cook Islands’ seafloor in never-before-seen detail. The work was done as part of Seabed 2030 - a collaborative project to produce a definitive map of the world ocean floor by 2030.

The three-year PARTneR–2 project aims to help countries in the Pacific become more resilient to the impacts of climate-related hazards.
