| Definition | The Sequoia Laser In-Situ Scattering and Transmissometry (LISST)-100-B is a self-contained unit which measures the scattering of LASER light at a number of angles. This primary measurement is mathematically inverted to give a grain size distribution, and also scaled to obtain the volume scattering function. The size distribution is presented as concentration in each of the grain-size class bins. The instrument has an optical path length of 5 cm as standard (2.5 cm optional) and measures particles over the size range 1.2 - 250 um in 32 log-spaced size classes. The standard maximum sampling speed is 4 size distributions per second and the instrument has a depth rating of 300 m. Optical transmission, water depth and temperature are recorded as supporting measurements. | ||
