River Tay Research
I am leading a project which surveys the River Tay and its estuary at least quarterly by boat, sampling at 10 sites between Perth and Broughty Ferry. The primary aim of this project is to quantify nutrient processing (nitrogen, phosphorus and carbon) along this part of the river. It is thought that microbial processes are likely to remove nitrate from the water, converting it into inert nitrogen gas, a process called denitrification. This means that less nitrate is transported to the North Sea, so the river and estuary would be performing a cleaning function. It is also possible that this process results in the production of a highly effective greenhouse gas, nitrous oxide.
Results of this project will be posted soon.
