While testing a LISST-ABS in the laboratory with field samples, Dr. Benjamin van der Waal of Rhodes University in South Africa noticed an apparent instrument drift. He was using samples extracted from a river for this testing, so that the samples were...
The optical scattering function (VSF) describes how incident light on a volume of water is scattered into various directions. It is an important inherent optical property of water – a term used by optical oceanographers. The VSF at small forward angles...
Upon first impressions the LISST-200X appears to be just a smaller version of the LISST-100X. However much of what makes the LISST-200X such an improvement over the LISST-100X is what lies deep inside the instrument. Let’s explore these features in...
Truly Portable Instrument Reduces Drilling Costs UPDATED 15 AUGUST 2017 The size distribution of drilling muds is frequently adjusted during the drilling process. As such, the particle size distribution must be measured frequently, several times a day....
Last updated: 11 May 2016 Turbidity as a surrogate for suspended sediment concentration (SSC) is commonly used and deeply established in practice. The shortcomings of turbidity as a surrogate for SSC are: The calibration changes with grain size; The...
