Size Parameter Codes: The Gravel2m code is the mass percentage of the sediment sample retained on a 2-mm sieve. If no sediments are retained, the value will be zero. The other parameter codes refer to the frequency percentage of sample in the size range. These data should not be adjusted for material retained on the sieve. Optional parameter codes to describe the statistical properties of the laser analyzer are included and may be reported. Default unit is percent within phi size.
