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...
Laser Diffraction Analysis of NIST 114q Cement per AASHTO Standard T353-14 Laser diffraction analysis of cements is a common industry practice to control quality of cements. Typically, companies must invest in multiple instruments at as many stations. The LISST-Portable|XR is truly portable –...
Holography permits a photograph-like view of particles in water. Photography suffers from a small depth of focus, so that only a small volume of water can be studied with each photo. In contrast, holography has total depth-of-field and therefore, permits viewing particles in a larger volume with each...
This page is written to explain how to interpret your data files. File formats and contents of processed datafiles are described here (note, the page numbers may differ by Manual versions): For LISST-100X User’s Manual, see Appendix A, page 117 [pages before 117 contain other numerical data, e.g....
This is a simple description. For detailed explanations see articles: Laser Diffraction-101 and -201. Particle Size Distribution (PSD) is a multi-parameter description of how the total concentration of particles is distributed into many size fractions. For example, a 32-element PSD means that the...
