LISST-AOBS (LISST-Acousto Optic Backscatter Sensor): No More Calibrations; and Uniform Sensitivity Across Wide Size-Range! B Why the Combination? The sensitivity (Volts/[mg/L] ) of Optical turbidity sensors varies inversely with grain size. Turbidity sensors are highly sensitive to fine particles,...
LISST-SL2 Is Demonstrated in Yangtze River, Wuhan, China [This article shows an example of river data from a boat; for bridge-lowered data, click here.] The Yangtze River hydrological facility is located in Wuhan on the western bank. A map of the location can be found here (30°37’41.59″...
Real Time Displays, and Immediate Averaged Results The new LISST-SL2 river sediment monitoring instrument is a greatly simplified and powerful device. The instrument transmits data immediately upon being lowered into water. Data can be viewed in real time, or after processing for averages. Click here...
This article is corrected and simplified,17 Sept. 2018 In Brief: The recommended upper limit of concentrations for LISST instruments is: Cmax = 375D/P micro-L/L where D is mean grain size in microns, and P is laser path-length in mm. Similarly,...

Particle size distribution (PSD) is a fundamental oceanographic measurement, with diverse biogeochemical applications including carbon cycle science, ecosystem and fisheries modeling, and harmful algal bloom (HAB) detection/prediction. There is optimism that estimates of PSD will be available from ocean...
These data show use of LISST-SL and -SL2 from bridges. For use from boats, click here. UPDATED 18 SEPT 2017 The LISST-SL2 instrument delivers the most powerful suite of sediment data. It is an isokinetic instrument (isokinetic means intake velocity matches river velocity). The parameters it measures...
UPDATED 09 SEPTEMBER 2017 As described in related articles, the LISST-ABS has a near-constant sensitivity (Volts/concentration) for sediment particles in the >30 micron size range [see Features section here]. In contrast, the sensitivity of optical turbidity degrades with increasing grain size. This...
