Harmful Algal Bloom

Among the thousands of species of microscopic algae at the base of the food chain, a few dozen produce toxins. These algae make their presence known during what is referred to as a "harmful algal bloom," or HAB. A HAB event may discolor the water, and are often called "red tides," but they frequently appear green, yellow, or brown, depending on the algae. Other species bloom in dilute, inconspicuous concentrations but are noticed because they produce potent toxins that kill marine organisms, or transfer through the food chain, harming organisms at multiple levels.

The causes of HAB events are poorly understood, but possible explanations range from natural mechanisms of species dispersal to anthropogenic actions such as nutrient loading, climatic shifts, or transport of algal species via ship ballast water.

HAB events now affect virtually every coastal area, an escalating and worrisome trend. As the impacts of mass mortalities of wild and farmed fish, marine mammals, seabirds, and illness and death in humans from contaminated fish or shellfish increase, research about the mechanisms of HAB events is urgently needed.

WET Labs builds absorption meters, scattering meters, and fluorometers that identify, characterize, and determine components of harmful algal blooms.

The Water Quality Monitor (WQM) is designed to deliver core biogeochemical water quality parameters in coastal ecosystems from a single integrated package.

ECO Triplet-w
The ECO Triplet custom optical instrument is now available with active anti-biofouling. It features an evolutionary design that builds off the bio-wiper and faceplate available on the current ECO line.
ECO Triplet
The Triplet is a a special-order, three-optical-sensor instrument available in a user-defined configuration. The Triplet addresses the need for multiple simultaneous scattering and fluorescence sensors for autonomous and unattended measurement platforms.
WETStar Chlorophyll Fluorometer
The WETStar fluorometer provides breakthrough performance for detecting various types of fluorescence. It uses a central axial optical tube to provide efficient signal output.
