Coasts

A NIWA-led programme to develop effective, and culturally-attuned strategies for managing the freshwater gold clam.

Temperatures around Aotearoa New Zealand are increasing, and not just on land. Amid a changing climate, significant marine heatwaves have impacted Aotearoa over the past decade and are expected to become more frequent and intense.

Introduced pests and diseases can harm the health of Aotearoa New Zealand's marine ecosystems, our seafood industry, and the social and cultural benefits that we derive from the sea.

Decisions about how we adapt to sea-level rise need to be based on information about our exposure to coastal flooding.

NIWA is leading a New Zealand partnership to map the South and West Pacific Ocean's seabed as part of a worldwide initiative to map the entire globe’s seafloor.

The main purpose of Ngā Waihotanga Iho is to provide tools for the public to measure environmental changes that occur in estuaries over time. These changes may occur due to natural processes and/or human activities.

This project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries.

A new online simulation game that enables New Zealanders to experience a climate-changed future and explore choices has been launched.

Understanding catchment to sea connections and estuarine processes for effective carbon sequestration and to ensure a healthy coastal marine environment under a changing climate.

Protecting New Zealand’s freshwater and marine environments from pests and diseases now and in future.

Could bubbles and strobe lights stop pest fish swimming where they’re not wanted?

NIWA and partners launch critical research to stop an invasive clam threatening New Zealand's freshwater ecosystem.
