Key contacts for Coasts and Oceans services

Chief Scientist -Coasts and Oceans

Barb has a research background in marine biosecurity and the environmental sustainability of aquaculture. Today she leads NIWA’s coasts and oceans research, which focuses on ecosystem-based approaches to managing activities in New Zealand’s marine estate, so that economic and social benefits are realised while vulnerable components of the ecosystem are protected.

Principal Scientist - Marine Geology

Geoffroy obtained a PhD in geology and geophysics from the university of Grenoble in 1987. He has since focussed his research on the geological processes that affect the ocean floor around New Zealand and in the South West Pacific region, with the aim to improve the understanding of natural geological hazards; identify, quantify and characterise sub-seafloor geological resources; assess the impact of seafloor resource extraction on the marine environment and develop predictive geophysical methods to map submarine substrate and habitats. He has led many oceanographic voyages and international research projects with France, the UK, Australia and the USA. 

Principal Scientist - Fisheries

Malcolm began his research career in the 1980s as a fisheries biologist. He worked extensively on stock assessment of deepwater fish (in particular orange roughy), before broadening his research interests to more general deep-sea ecosystems. He studied seamounts for many years, and headed the Census of Marine Life on Seamounts, a major 6 year international research programme. His studies have involved a lot of time at sea; with over 70 surveys, including submersible dives, and international work in the Antarctic and southwest Pacific. Currently he leads NIWA research projects describing the biodiversity of deep-sea habitats, assessing ecological risk to these habitats and communities from fishing and mining activities, and ways to improve the management of environmental impacts.


Principal Scientist - Marine Biology

Wendy Nelson specialises in marine phycology, particularly the biosystematics of macroalgae of New Zealand, with research on floristics, evolution and phylogeny, as well as ecology, and life history studies. Recently she has worked on the systematics and biology of red algae including corallines, distribution and diversity of seaweeds in harbours and soft sediment habitats, and seaweeds of the Ross Sea and Balleny Islands. Wendy leads NIWA's biosystematic research team.

Principal Scientist - Marine Ecology

Judi is a soft-sediment benthic ecologist, with a statistical background and a PhD from Abo Akademi in Finland. She has worked mainly on issues of scale, study design and merging ecological theory with empirical observations. Her interests include: Coastal and estuarine marine ecology; Biological and ecological mapping; Spatial and temporal variation in populations and communities; Ecological impact assessment, particularly of diffuse source and/or broad-scale effects; Design and implementation of ecological monitoring programmes; and Functional, community and habitat biodiversity.

Principal Scientist - Marine Ecology

Graeme leads NIWA's Marine Biosecurity research programme, which is a partnership involving NIWA, the Cawthron Institute, and the Ministry for Primary Industries. He is a member of the IUCN Invasive Species Specialist Group, a Technical Advisor to the GEF/UNDP/IMO Global Ballast Water Management Programme and sits on advisory panels for implementation of New Zealand's Biosecurity Science Strategy and MAF Biosecurity NZ's Biosecurity Surveillance Committee. Graeme's research is primarily on the design and implementation of marine pest surveillance, including early detection, baseline and delimiting surveys for unwanted marine organisms.
