Project Title: Characterisation of stable isotope fractionations during reactive transport of phosphate in groundwater discharging to a groundwater fed lake (Lough Gur, Co. Limerick)
Project Description: Lake groundwater discharge is often overlooked and the focus of this study is the novel application of phosphate (δ18OP) as a tracer of P to a groundwater fed lake. Other established isotope techniques will characterise the source of water and biogeochemical processes contributing to nutrient cycling within the lake.
