Key contacts for Freshwater and Estuaries services

Chief Scientist - Freshwater and Estuaries

Scott is an ecosystems ecologist. His research focuses on effects of land and water use on biological communities, ecosystem processes and water quality.  This research has been carried out in rivers, estuaries, coral reefs, lakes, aquifers and open ocean.  Current research areas include water quality analysis and tools for assessing land-use effects. Scott is Chief Scientist of NIWA's National Centre for Freshwater and Estuaries.

Hydrologist

Christian is a hydrologist with a MSc in small scale hydrology (University Joseph Fourier- France) and PhD in Soil Physics (University Joseph Fourier- France). His research interests include developing improved methods for making hydrological predictions in ungauged catchments, understanding the spatial variability in hydrological response through measurement, conceptualisation and modelling of surface water and groundwater flow across landscape and temporal scales, snow hydrology and uncertainty quantification in decision making process in watrer resource and weather related hazard. 

Principal Scientist - Freshwater Ecology

Paul holds a BSc Hons from Leicester University and an MSc in biological sciences from the University of Waikato and has a background in wetland and aquatic plant ecology. He specialises in freshwater biosecurity, especially risk assessment, developing strategies for the prevention of aquatic weed spread and protection of unimpacted water bodies, and designing and implementing eradication programmes for aquatic weeds. He works closely with a wide range of central and regional authorities in the field of biosecurity. He is also author/co-author of three books on the identification of common weeds, grasses, sedges, rushes and weed seeds in New Zealand. He also has experience in wetland ecology and conservation needs and management plans for nationally endangered aquatic and wetland plants. Paul joined NIWA in 1994 and was appointed Programme Leader – Freshwater Biosecurity in July 2015. He has been a Principal Scientist – Freshwater Ecology since 2004. He previously worked with the Ministry of Agriculture and Forestry coordinating eradication programmes for nationally important weeds.

Aquatic Biogeochemist

Fleur is an aquatic biogeochemist with a MSc (Hons) in Biology and Environmental Planning from University of Waikato and a PhD in Physical Geography from Durham University, UK. She leads NIWAs Aquatic Rehabilitation and Protection research programme. Fleur joined NIWA’s aquatic plants group in 2002. She has a wide network of science and stakeholder relationships and she coordinated NIWA’s Envirolink research from 2014 to 2016. From 2010 to 2016 she led work to update the New Zealand instream plant and nutrient guidelines for Regional Councils. Her current research interests include evaluating the effectiveness of targeted riparian buffers, riparian shade effects on instream plants, aquatic plant ecology and management, seagrass restoration and seagrass responses to sediment impacts in estuaries. She is a founding member of the Australasian Seagrass Restoration Network.

 

Principal Scientist - Catchment Processes

Sandy (Alexander) Elliott applies mathematical techniques to address water quality issues, especially predicting the effects of diffuse pollution and its control at catchment scale. His background spans from experimental work on transport process in flumes and on hillslopes, to delivering national-scale catchment modelling software, and from urban areas to the coastal impacts. He has developed and modified several catchment models for water quality, including the national CLUES model, and applied these in a wide range of settings in New Zealand. His current interests include techniques for shifting across spatial and temporal prediction scales and providing practical catchment models suitable for managing water quality within limits. He currently leads NIWA's Eutrophication Risk Assessment programme, and the Our Land and Water Interoperable Models programme.

Hydro-ecological Modeller

Coastal and Estuarine Physical Processes Scientist

Andrew specialises in estuarine sedimentary processes and biogeomorphology, with 25 years experience as a research scientist. He holds a BSc and MSc (1st Class Honours, University of Auckland) and a PhD (The University of Queensland).  Specialist skills and interests include sediment geochronology, sediment-source tracing using compound specific stable isotope (CSSI)   techniques, mangrove ecology and morphological evolution, geostatistical methods and land use impacts on estuaries.  Andrew leads NIWA’s Catchments to Estuaries Programme, which is focused on understanding and predicting the connections between catchments and estuaries to improve the management of diffuse-source contaminants (i.e., fine sediments, nutrients and microbes) in estuaries. 

Andrew’s research involves multi-disciplinary research collaborations with scientists from NZ and international institutions. Projects include reconstruction of environmental changes using CSSI and radioisotope techniques, investigating human impacts on estuarine sedimentation regimes, predicting effects of fine suspended sediments and dissolved substances on estuarine water clarity, and the biophysical processes and feedbacks driving mangrove-forest ecology and biogeomorphic evolution. Andrew applies techniques and understanding gained from research to assist resource managers with integrated catchment-estuary management.
