Atmospheric analysis

Spatially explicit disturbance/recovery models are a cellular automaton that uses a mechanistic approach to investigate recovery rates of benthic species following disturbance events.

Resource trade-off models are spatial models that use biological, environmental and socio-economic data to optimise management (protected area designation) across potentially conflicting uses, or across different ecosystem services.

MICE (Models of Intermediate Complexity) is a type of ecosystem model that is question-driven, and contains a limited number of components and ecological processes.

At NIWA, we consider all components of the marine ecosystem important when trying to better understand the role of dynamic, ecosystem processes on the distribution and abundance of marine organisms in New Zealand’s marine environments.

Approximately 500 Aquatic invertebrate taxa are described in this database, made available to assist with the identification of specimens.

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.

A large area of high pressure will take up residence east of New Zealand for the next few days, bringing more unusual springtime warmth to parts of the South Island from tomorrow through to late next week, says NIWA forecaster Seth Carrier.

A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Across the North Island, soil moisture levels have generally not changed significantly during the past week, while across the South Island, soil moisture levels have generally decreased.

An immense dome of high pressure stretched across the Tasman Sea onto the South Island yesterday, bringing the highest temperatures across New Zealand since April.

The first weekly update for the 2017-18 summer describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent.
