Applications accepted all year round
This is a self-funded, 3 year full-time or 6 year part-time PhD studentship, to commence in October or February.
UK water companies regularly suffer problems with blooms caused by algae and cyanobacteria. Algal blooms can contaminate water supplies with toxins, cause taste and odour problems, and impact on the effectiveness of the equipment used for water treatment.
It's estimated that eutrophication costs the UK more than £114 million per year, and the problem of excessive algal growth is predicted to get worse under future climate change scenarios.
You'll investigate the novel application of Fast Repetition Rate Fluorometry (Frrf) to measure quantum yield (Fv/Fm), an indicator of algal 'health', to better understand and predict algal blooms.
The water industry is particularly interested in the potential of FRRf, together with easily-measurable environmental variables such as light, temperature, flow and nutrients, to provide an early warning system for bloom development.
The work will include:
- working closely with CEH, you'll monitor sites on the River Thames, which often suffer from eutrophication problems, leading to problem causing algal blooms
- high-frequency (hourly) monitoring of nutrient concentrations, temperature, dissolved oxygen, light and flow, alongside sub-daily biological data from flow cytometry and FRRf (blue and red PhytoFlash), to produce a truly unique dataset that will allow us to better understand the timing, duration and magnitude of blooms in rivers
- analysing data from a pilot study of Frrf on the River Thames, using time series analysis, determining whether changes in Fv/Fm can provide an early warning system for algal blooms
Initial results suggest that FRRf can provide powerful new insights into phytoplankton dynamics in rivers and allow water companies to rapidly intervene to prevent bloom formation.
