NIWA is developing a model to help predict the effects of land-use change on nutrient concentrations in estuaries. Follow the links to read the project pages on the CLUES estuarine toolkit.
Seagrass meadows provide vital habitat for juvenile fish, but are disappearing at an alarming rate in many places. NIWA scientists are finding out more about the role seagrass plays in the life of young fish.
A new post doctoral fellow at NIWA – Dr Claire Guy – is investigating the ecological impacts of ocean acidification on key Antarctic shellfish.
As the climate changes and sea levels rise, coastal communities become more vulnerable to hazards like coastal inundation and erosion. NIWA is working with coastal communities and councils on how to adapt to these impacts.
Scientists from NIWA and Massey University have surveyed rig shark (aka lemon fish) nurseries in 13 estuaries nationwide. They also recorded a number of environmental parameters, which will help scientists understand more about the preferred habitats of rig sharks.

The New Zealand coast is a marine biodiversity hotspot, inhabited by an estimated 65 000 species, many of unique to New Zealand. Knowing what we have and where is crucial to protecting this wealth of biodiversity and the environmental services it delivers. A recent mapping project meets this need.
The Bay of Islands coast is under increasing pressure from human activities, both land-based and marine. As part of the government’s Ocean Survey 20/20 programme, Land Information New Zealand (LINZ) commissioned NIWA to carry out a comprehensive survey of the region’s seafloor habitats and biodiversity.
Research has revealed key differences in seafloor communities and habitats inside and outside the Separation Point trawl fishing exclusion zone in Tasman Bay. These have important implications for valuable benthic fisheries in the area.
What will future land use and climate change do to sediments entering southern Tauranga Harbour? To find out, Environment Bay of Plenty commissioned NIWA to model the sources and fates of sediments under various scenarios over a 50-year period.
