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 (Freshwater HAB’s), Phycoerythrin (Marine HAB’s), Chlorophyll and beam attenuation.

Features

  • Complete package based on Small Angle Forward Scattering Laser Diffraction Technology
  • Measures Particle Size and Concentration in 36 Size Classes
  • Integrated with Turner Designs Cyclops-7F fluorometers engineered to detect Phycocyanin (freshwater HAB’s), Phycoerythrin (marine HAB’s), and Chlorophyll
  • Internal programmable datalogger
  • Small and Extended Battery Packs available for self-contained operation
  • USB connection to PC for programming, offloading and real-time size distribution displays
  • Programmable, autonomous data collection
  • Integrated Depth and Fast Response Temperature Sensors
  • Towable or integrated on profiling package or vehicle

Fluorometer Performance
The Turner Designs submersible instrumentation modules used in the LISST-HAB includes single-channel fluorometers for detection of chlorophyll, freshwater and marine HAB’s. Together with particle information from the LISST, this package solution provides a comprehensive picture of a HAB and its development.

FAQ

What is the LISST-HAB exactly?

The LISST-HAB is a LISST-200X integrated with three Turner Designs fluorometers, sensitive to algae pigments and Chlorophyll. The fluorometers are powered by the LISST-200X, which also controls their sampling. The fluorometer signals are then read by and integrated into the LISST-200X datastream for a unified dataset.
