Paul Van Ruth

Research Scientist – Microalgae

 Paul_Van_Ruth2

Areas of expertise:

Phytoplankton and zooplankton ecology, taxonomy and productivity, nutrient dynamics, biological oceanography, environmental monitoring, data and statistical analysis

Countries of work experience:

Australia

Overview of experience and qualifications:

Paul van Ruth is an experienced biological oceanographer and plankton ecologist who has worked extensively in the shelf and coastal waters of southern Australia. Paul investigates the environmental factors that shape marine planktonic communities via examinations of spatial and temporal variations in nutrient concentrations, biogeochemistry, and irradiance, and the physical factors that drive variation in these parameters. This work has helped Paul understand the complexity of competition between microalgae for essential requirements, and the way in which this influences the ecology of the planktonic community. Paul has published his work in leading scientific journals and presented at international conferences.

Paul is currently funded as the Marine Innovation South Australia (MISA) Microalgal Research Scientist at SARDI Aquatic Sciences.  His role involves the design and implementation of studies of biological oceanography and plankton dynamics in South Australian coastal waters to provide information sufficient for management decisions to be made regarding the likely impact of industrial, commercial and recreational activities on plankton communities and food web structure. These include investigations of the impacts of reverse osmosis desalination plants, and activities associated with waste water treatment, aquaculture and fishing, and mineral exploration.  He collaborates with the Oceanography Program on a variety of projects that are aimed at providing further insight into the impact of climatic variation on plankton dynamics.
