Base data: median values for the correlation of water content to organic content (n = 785), and for the particle density of inorganic matter = 2.8 (n = 444) and of organic matter = 1.6 (n = 444) according to pychnometer determinations.

y = a + b . x + c . x2 + d . x3 + delta y; z = a + b . y3 + c . y32 + d . y33; p = 1/(a + b . y3 + c . y32 + d . y33)
x = film density; y1 = thickness in mm of the Al-wedge; effective overburden pressure/cm sediment depth = y2 - density of water.

Density-related parameters. Some corresponding values.

The relationship between the wet and the dry bulk density is given by some corresponding values in the table above. The given values of organic content as a density-related parameter in the table are uncertain, and should only be regarded as median values for the correlation of water content to organic content in the 785 analysed sub-samples.
