Atmospheric analysis

A team of international researchers leaves Wellington this weekend to explore the bottom of the Kermadec Trench – one of the deepest places in the ocean.

A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

Does climate change affect the position of the Subtropical Front around New Zealand? This has important consequences for New Zealand's climate and biological productivity.

An ambitious scientific expedition involving 30 scientists from around the world leaves Perth next week bound for the East Coast of the North Island.

This voyage is the first of a series of expeditions exploring selected trenches of the Pacific Ocean, starting with the Kermadec trench. It will investigate carbon and nutrient cycling by microbial communities in trenches exposed to different rates of organic carbon supply.

New Zealand winters are a month shorter than they were 80 years ago, NIWA scientists say.“This is a consequence of rising temperatures around the globe, and such trends in colder temperatures and frosts will influence the life cycle of plants and animals” - Dr Brett Mullan.

Unlike other ecosystem models, machine learning is built solely from the information it is presented.

Ecopath with Ecosim (EwE) is trophodynamic modelling software that uses a mass-balance approach to describe ecosystem based, marine food web interactions.

LIEM synthesizes field measurements with a priori knowledge of ecosystem structure and physiological capabilities, to constrain material flows through an ecosystem.
