• REON II Multiparameter Sonde
    measures the following parameters:
    • Turbidity
    • Chlorophyll  
    • Color dissolved organic matter (CDOM)
    • Dissolved oxygen
    • pH
    • Conductivity (salinity)
    • PAHs (toxic petroleum compounds)
  • METEOROLOGICAL TOWER (Real-Time Hydrologic Stations/RTHS)
    that measures wind direction, flow and speed, precipitation, stage height (height of the water's surface in relation to the riverbed), as well as air temperature and barometric pressure.
    to measure the direction and flow rate of water -- fundamental information to set a baseline for other hydrologic parameters.
    with multiple sensors to take a series of measurements of the river at several depths and/or locations:

Conductivity (salinity), Temperature and Depth (CTD):
These basic hydrologic parameters that are important alone, but when coupled with others, provide scientists with important information about the water in the river.

Laser In-Situ Scattering and Transmissometery (LISST):
A narrow red laser beam shone into the water can measure the amount of particles in the water and their size range.

Three-Channel Fluorimeter (FL3)
A unique instrument that provides biological, physical and chemical data:

Chlorophyll A (biological) 
measures the presence of algae, which can be a food source at certain levels, but overabundance can be detrimental to ecosystem.
Fluorescein (physical) is a harmless green dye that, when placed in the water, can be used to track water movement in the river. This can be useful for modeling and predicting where pollutants can flow.
Color Dissolved Organic Matter (CDOM) (chemical) is of interest as a natural water mass tracer. Dissolved organic matter can affect how organic contaminants and metals distribute themselves in the environment.

Optical Oxygen Sensor:
This new kind of sensor uses optical fluorescence technology to detect the amount of oxygen in the water. Oxygen is another important indicator of ecological health.
