I am quantifying sulphur biogeochemistry in the highly reducing sediments typically found beneath fish farms.  I investigate the relationships between the following sediment properties: pore water sulphide concentrations, insoluble sulphide species, redox and oxygen demand.

These sediment properties are being examined in detail during the recovery processes that occur in response to fish farm impacts. Together, these measurements provide information on the degradation rates of fish farm wastes over long periods (several months/years) and thus contribute to modelling.

Research objectives:

  1. To investigate the role of sulphur chemistry in sediment recovery
  2. To develop methods for measuring sulphides in fish farm sediments
  3. To quantify microscale relationships between oxygen, pH and hydrogen sulphide concentrations in response to a) enrichment level and b) seasonal temperature changes during short term recovery processes
  4. To quantify sulphur speciation in recovering fish farm sediments in response to enrichment level and seasonal temperature
  5. To identify if sulphur plays a role in the anaerobic oxidation of methane beneath fish farm
