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
The Ross Sea Region Research and Monitoring Programme (Ross-RAMP) is a five-year research programme funded by the Ministry of Business, Innovation and Employment (MBIE) and run by NIWA to evaluate the effectiveness of the Ross Sea Marine Protected Area.
The main breeding population of New Zealand sea lions at the Auckland Islands has halved in size since the late-1990s; NIWA scientists are working with the government and experts from around New Zealand and overseas to understand why.
Estuaries and coasts provide a wide range of benefits to New Zealanders – “ecosystem services”. However, we still don’t know enough about these ecosystem services – a challenge NIWA and other scientists are tackling with a new technique.
We know that waves cleanse estuaries of silts and clays, keeping intertidal flats sandy and healthy. But how big do waves have to be to be effective in this way? New research shows that very small waves can be just as effective as big waves.
Changes to the local environment and over harvesting have damaged shellfish populations in many estuaries. These projects examine the most effective way to restore these habitats and allow healthy populations of shellfish to return.
NIWA has developed an Urban Stormwater Contaminant (USC) model to enable urban planners to predict sedimentation and heavy metal accumulation in estuaries and identify problem areas in order to target mitigation measures.
