©2020 Biological and Chemical Oceanography Data Management Office.Laser diffraction is particle sizing technique for materials ranging from hundreds of nanometers up to several millimeters in size. Laser diffraction measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample. One example is the Beckman Coulter LS200.
| Dataset Name | PI-Supplied Description | PI-Supplied Name |
|---|---|---|
| Core data collected in the Brazos River Plume, TX during 2017-2018 | Malvern Mastersizer 2000 | |
| Grain size and radiometric data from multi-core sediments collected Fall 2017 from the R/V Acadiana in the northwestern Gulf of Mexico to assess Hurricane Harvey impacts | The Beckman Coulter LS 13 320 measures the size distribution of particles suspended either in a liquid or in dry powder form by using the principles of light scattering. Each particle's scattering pattern is characteristic of its size. The pattern measured by the LS 13 320 is the sum of the patterns scattered by each constituent particle in the sample.The LS 13 320 incorporates Beckman Coulter's patented PIDS (Polarization Intensity Differential Scattering) technology to provide a dynamic range of 0.017 μm to 2000 μm.

| Sediment grain size data collected from a shallow subterranean estuary (STE) in Gloucester Point, Virginia USA, from 2018 to 2019 | LDPSA, model: LS 13 320, Beckman Coulter | |
| Physical and geochemical measurements of water and sediments measured from a UNCW 20-ft Center Console Boat in the Cape Fear River Estuary, NC in 2009 (Estuarine ANAMMOX project) | A Beckman model LS-200 was used to to measure the distribution of sediment grain sizes.
