RECON (River, Estuary and Coastal Observing Network)
Encyclopedia
RECON is the River, Estuary, and Coastal Observing Network created and maintained by Sanibel-Captiva Conservation Foundation (SCCF).

Description

RECON is the first-of-its kind observing system funded from a majority of 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
Nitrate
The nitrate ion is a polyatomic ion with the molecular formula NO and a molecular mass of 62.0049 g/mol. It is the conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically-bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a...

Fluorometer
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. These parameters are used to identify the presence and the amount of specific molecules in a medium...

Chlorophyll
Chlorophyll is a green pigment found in almost all plants, algae, and cyanobacteria. Its name is derived from the Greek words χλωρος, chloros and φύλλον, phyllon . Chlorophyll is an extremely important biomolecule, critical in photosynthesis, which allows plants to obtain energy from light...

One of the stations also incorporates a Nortek Aquadopp 2-dimensional current profiler sampling at 1 MHz for flow measurements. Data are currently collected hourly and transmitted in near-real time via cellular modems to a dedicated SQL

Extensive field testing by SCCF has led also to several innovative modifications to improve duration and robustness of these instruments. 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. Other enhancements include a user-friendly website designed for scientists, decision-makers and the general public. Information disseminated through the website includes concise definitions of water quality parameters measured and how to interpret trends in water quality at high resolution. To maintain data quality control, water samples are collected to validate instrument settings and readings with traditional wet-chemistry methods. Water samples are analyzed by a state-certified Florida Department of Environmental Protection
