This Note shows how the calibration of the LISST-ABS acoustic backscatter sensor and of optical backscatter sensor (OBS) changes when water contains a broad distribution of particle sizes, and why LISST-ABS is inherently superior. Particle size distributions...
Scintillation is what makes stars twinkle. It is what causes mirage in deserts or on hot surfaces. It is what causes shimmer underwater in the vicinity of hot vents in oceans. These effects result from temperature fluctuations in air or water. The same...
How to Compute the Mean Particle Diameter from a LISST Volume Distribution [Sequoia, March 26, 2010] In the table below, the computation of the mean particle size from a LISST volume distribution is outlined.Column A is the size class...
Is there a low velocity threshold for the LISST-SL? Does it need a minimum flow speed in order to sample? What is that? Absolutely! The internal pump in the SL will adjust the intake velocity to match the ambient flow speed in order to make the sample...
The acceptance angle of the LISST-100X / LISST-STX transmission measurement differs between instruments: IN AIR, the LISST-100X type C has an acceptance angle of 0.0177 degrees while a type B has an acceptance angle of 0.0353 degrees. The discontinued...
