LISST-HAB

Harmful Algae Bloom (HAB) Instrument

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

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.

Do the fluorometers report CONCENTRATIONS of the different fluorescent pigments?

No. The data you get from the LISST-HAB fluorometers are raw voltages. You must convert those to pigment concentrations yourself by calibrating the fluorometers with pigment samples.

Fluorometers do not provide perfect measurements of concentration: They are imperfect proxies for the specific compounds. Calibrating them involves your scientific judgement, and that may be different for different environments. For this reason Sequoia does not calibrate them in advance.

Can I rent the LISST-HAB?

No.
