A key aim of the project was to identify environmental conditions responsible for the occurrence of blooms of blue-green algae (cyanobacteria) in the Darling River. Emphasis was given to describing the role of phosphorus and identifying its major sources of supply. Specifically we sought to:
- develop an empirical model of phytoplankton growth
- identify the main environmental conditions that trigger blooms of cyanobacteria
- identify the amounts and the physico-chemical forms of nutrients transported in the river
- determine the factors that control ė bioavailabilityî (ie. availability to phytoplankton) of the various forms of major nutrients
- assess whether the present phosphorus concentrations in the river are higher than they were before European settlement
- identify and quantify the major sources and types of phosphorus reaching the Darling River
The influence of riverine conditions on the growth of phytoplakton was investigated in a section of the Darling River near the township of Bourke. Sediment transport was investigated from samples of suspended particles and bottom sediments collected from sites distributed along the length of the river. Catchment sources of particles were investigated using soil samples collected from transects of 100km length distributed across different land types.
