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.
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.
Parameters Measured
Operating Concentration range
| Fluorometer ranges | ||
|---|---|---|
| Minimum Detection |
Linear Range |
|
| Phycocyanin | 2 ppb | 450 ppb |
| Phycoerythrin | 0.1 ppb | 75 ppb |
| Chlorophyll | 0.03 ug/l | 50 ug/l |
Due to varying requirements and standards for fluorometry, the fluorometer outputs are reported in raw Volts. Absolute calibration, if any, must be executed by users according to their own requirements.

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.
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.
No.
