Seasonal variation in primary productivity and food web dynamics in a coastal upwelling system: the eastern Great Australian Bight

A top-up for a PhD scholarship is available to investigate seasonal variation in primary productivity and food web dynamics in the eastern Great Australian Bight (GAB).  This will involve examinations of primary productivity via the uptake of radioactive carbonate (14C) and fluorometry, assessments of size-fractionated phytoplankton biomass and community composition via pigment analysis with High Pressure Liquid Chromatography, and food web studies based on the relative enrichment of stable isotopes of carbon and nitrogen in organisms in lower trophic levels (microbes à zoo/ichthyoplankton) in comparison to their food sources.  Changes in these parameters will be assessed in the context of seasonal variation in meteorology and physical and chemical oceanography with the objective of identifying key environmental drivers of variability in primary productivity and food web dynamics in the eastern GAB.

The top-up is available for Australian Postgraduate Award or Divisional (PhD) scholarships of $15,000 per annum (for 3 years), with $10,000 to augment the Ph.D. scholarship and $5,000 for operating.

The PhD candidate will be based at the Aquatic Sciences division of the South Australian Research and Development Institute (SARDI) and supervised by researchers at SARDI Aquatic Sciences.

The successful applicant will be required to enter into a formal agreement setting out the specific terms and conditions governing their participation in the GAB Research Program.  For more details on these terms and conditions please contact Dr Steven Lapidge, Research Director Great Australian Bight Research Program, SARDI: steven.lapidge@sa.gov.au, 0401 990 367.

The top-up scholarships are for PhDs who commence early in 2015.

For more information on the research theme and contact details of how to apply for the scholarship please contact Dr Paul van Ruth: paul.vanruth@sa.gov.au, (08) 8207 5421.
