What is it? Fluorometers, often used in oceanography, measure the fluorescence of algae, dyes or pollutants in the water by measuring the concentration of Chlorophyll-a.

Why is it important? Firstly, this can be helpful when making algae bloom predictions by estimating the concentrations of phytoplankton and blue-green algae. It can also be used for dye tracing studies, turbidity dredge monitoring, and/or pollutant tracing. Most importantly, because phytoplankton are the base of the ocean food chain and food for zooplankton (tiny planktonic animals), as the phytoplankton levels increase so do their predators which are an important source of food for fish and seabirds.

What does it mean? This test can provide you with important data that affects many elements of water quality.
