Reclassifying karengo (nori)
Research ProjectThe seaweed known colloquially as nori in Japanese - used for making sushi - or karengo in Maori has been reclassified by an international team of scientists including NIWA's Dr Wendy Nelson. -
Globalisation of aquatic plant pests
Research ProjectNew Zealand's geographic isolation and relatively recent colonization provide the opportunity for a unique genetic analysis of plant movement patterns to be explored. -
Sedimentation in New Zealand estuaries
Research ProjectEstuaries in New Zealand are experiencing sedimentation at higher rates than before humans arrived here: this represents a loss both for land and estuary productivity. We need to better understand what has been happening so that we can predict the future and fight these losses. -
Aquatic weed risk assessment model (AWRAM)
Research ProjectA significant threat to the biosecurity of New Zealand's freshwater habitats comes from plants that have been intentionally introduced. -
Tracking river plumes
Research ProjectRiver plumes form one of the primary connectors between river-estuary systems and the coastal ocean. -
Oceans 20/20
Research ProjectThe Ocean Survey 20/20 (OS 20/20) programme aims to provide NZ with better knowledge of its ocean territory. -
Controlling water weeds with grass carp
Research ProjectA Ministry for Primary Industries-funded study has shown that grass carp, in enclosures, can be used as an effective means of controlling invasive plant species in our waterways. -
Coastal and oceanic dispersal modelling
Research ProjectUnderstanding how material released into the ocean spreads is very important in the case of oil spills, sediment transport and the release of invasive species. -
Surface Ocean Aerosol Production (SOAP)
Research ProjectHow do marine micro-organisms influence the earth's atmosphere and climate? -
Waikato River Independent Scoping Study (WRISS)
Research ProjectMany of New Zealand's aquatic ecosystems, and their services, are in a degraded and often worsening state. NIWA is involved in research and consultation' aimed at improving the health of our freshwater systems. -
Chemistry-climate modelling
Research ProjectThis research project focusses on modelling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models. -
Submarine faulting beneath Pegasus Bay
Research ProjectIn September 2010 and February 2011, two devastating earthquakes (M7.1 and M6.3 respectively) hit the Canterbury region
