About the Project
Via the collection and dating (210Pb, 137Cs) of lake sediment cores (n=3) from three different land use regions of Loktak Lake this project will quantify changes in sedimentary organic content, aquatic ecology and pesticide accumulation rates since the initiation of human impacts upon the lake. The concentration and identification of pesticides will be established over time, along with the concentrations of algal pigments and stable isotopes (δ13C, δ15N, C/N ratios) to determine the impact of aquaculture, pesticide use and climate change upon the lake.
The aims of this project are to:
1. Reconstruct (the past c. 300 years) the initiation of aquacultural practices across the three basins of Loktak Lake and identify the impacts this has had on aquatic ecology
2. Reconstruct the initiation of pesticide use across the three basins of Loktak Lake across and identify and quantify the key chemicals used
3. Quantify changes in lake sediment retention and organic carbon burial since the formation of the Ithai dam
The student will work between the National Environmental Isotope Facility at the British Geological Survey and the School of Geography at the University of Nottingham, being embedded within a team of isotope geoscientists and palaeolimnologists.
This project is in receipt of additional funding from the BGS University Funding Initiative.
Applicants must have a minimum of a 2:1 class degree in geography, geology or environmental sciences or a masters degree in a relevant field.
