WebDec 19, 2024 · Measurements of optical properties have been used for decades to study particle distributions in the ocean. They are useful for estimating suspended mass concentration as well as particle-related properties such as size, composition, packing (particle porosity or density), and settling velocity. WebThe precision of the Thermal-Optical method of analysis, measured as a relative standard deviation, falls into the 4-6% range for samples that are in the concentration ranges of 5 to 400ug/cm2 for OC, and 1 to 15ug/cm2 for EC. This relative standard deviation range applies to the OC/EC speciation values as well as to the total carbon.
