FAQ

How does the LISST-Black help in an oil spill situation?

First, one has to detect if and what kind of oil (crude? refined?) has been spilled. The fluorometer package on the LISST-Black will assist in that.

Second, it is important to optimise dispersant use in case dispersants have to be applied to the spill. The size information and volume concentration measurement from the LISST-Black will assist in that.

There are numerous papers in the literature giving examples of the above applications. A non-comprehensive list can be found in our library (Library/Technical Papers).

What is the LISST-Black exactly?

The LISST-Black is a LISST-200X integrated with three Turner Designs fluorometers, sensitive to hydrocarbons. 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-Black 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.
