Abstract Information :
Chelsea Tryptophan and FDOM sensors were deployed close to the outflow into a bay located in North Devon. These sensors collected reliable data uninterrupted and unattended for over 6 months. Together with the Chelsea Tryptophan and FDOM sensors, other sensors monitoring pH, Turbidity, Disolved Oxygen and Ammonia were also deployed at the same site. Bacterial counts from sampled water in the same vicinity as the monitoring site enabled comparision of real time data from Tryptophan and FDOM sensors. The presentation will demonstrate that the data obtained over many months clearly remained 'good data' with no perceivable impact of either sensor degradation or fouling. The combined Tryptophan and FDOM sensors produced data clearly unaffected at levels of turbidity that would typically impact on optical sensor output. The presentation will also demonstrate the strong correlation between the Ammonia sensor deployed and the Tryptophan output, indicating potential for a low maintenance robust alternative to Ammonia ISEs for river monitoring.
