LISST-HAB
HARMFUL ALGAE BLOOM (HAB) INSTRUMENT
The LISST-HAB is a self-contained, stand-alone instrument system for use on profiling packages, towed and remote vehicle applications, for deployment during a HAB event. The system will continuously measure particle size distribution and concentration, along with the fluorescence of Phycocyanin, Phycoerythrin, Chlorophyll, and Beam Attenuation.
