RECON is funded primarily by private donations to SCCF's Marine Laboratory. Seven fixed locations stream water quality data from in situ Satlantic instrument packages. 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. One of the stations also incorporates a Nortek
