Evaluation of novel sampler for time-integrated nutrient concentrations in water (Bachelor/Master)
You are going to test Time Integrating, Micro Flow, In situ Extraction (TIMFIE) sampler for the determination of nutrient concentrations in water.
The TIMFIE is a new, low-tech water sampler that has been successfully used so far for the determination of the pesticide concentrations.
You will use a somewhat modified TIMFIE to sample water and thereafter determine concentrations of different nutrient forms (nitrate nitrogen (N), phosphate phosphorus (P), total N and total P as well as suspended sediments (SS)).
The performance of the TIMFIE sampler will be evaluated for two monitoring objects, one arable field and one small catchment, which are included in the national monitoring programs. Thereby the results achieved after sampling with TIMFIE can be evaluated by comparison with corresponding data collected within monitoring programs, and even results from high-resolution sensors, if such exist.
The work includes sampling in the field, laboratory work and analysis of data generated from the project and as well as existing data.
