Multiparameter Sondes for Fresh Water Monitoring

Description

We are looking to purchase water quality monitoring equipment for the Upstream Thinking project, funded by South West Water. The project aims at understanding the impact of catchment interventions on water quality at catchment scale in both streams and reservoirs. The equipment will be deployed to give us an understanding of (1) turbidity and DOC issues in streams, and (2) algae blooms in reservoirs. In each environment, we seek to deploy a number of sondes (i.e. up to 28 in total). The equipment will be deployed for a period of time and accessed periodically. It will need to include appropriate biofouling prevention, data logging and power capacity. The data download needs to be similar for all sensors, and all cables and/or hardware must be provided.

The equipment will be deployed to give us an understanding of (1) turbidity and DOC issues in streams, and (2) algae blooms in reservoirs. In each environment, we seek to deploy a number of sondes (i.e. up to 28 in total) comprising the following combinations of parameters: Sonde A: o pH o Conductivity/temperature o Dissolved Oxygen o Turbidity Sonde B: o pH o Conductivity/temperature o Turbidity o fDOM Sonde C: o Turbidity o Dissolved Oxygen o Conductivity/temperature o Chlorophyll a o Phycocyanin The equipment will be deployed for a period of time and accessed periodically.
