River, Estuary and Coastal Observing Network

The sensor array includes a chemical-free nitrate sensor (ISUS), a CTD (conductivity, temperature, and depth) and fluorometer package for depth, turbidity, temperature, dissolved oxygen, salinity, and chlorophyll a fitted with a bleach injection system (WETLabs, Water Quality Monitor), and a CDOM fluorometer.

Data are currently collected hourly and transmitted in near-real time via cellular modems to a dedicated SQL database and can be viewed also in near real-time and plotted at RECON's website.

Extensive field testing by SCCF has led also to several innovative modifications to improve duration and robustness of these instruments.

[4] These include a non-toxic exterior anti-fouling paint, copper foil applied to all connectors and cables, and a custom designed support structure to attach to existing pilings.

To maintain data quality control, water samples are collected to validate instrument settings and readings with traditional wet-chemistry methods.
