2.2 Porositiy and Wet Bulk DensityFig. 2.4 Comparison of wet bulk densities determined on discrete samples by weight and volume measurements andcalculated from gamma ray attenuation. (a) Cross plot of wet bulk densities of gravity cores PS1821-6 from theAntarctic and PS1725-2 from the Arctic Ocean. The dashed lines indicate a difference of ±5% between both data sets.(b) Wet bulk density logs derived from gamma ray attenuation for two 1 m long core sections of gravity core PS1725-2.Superimposed are density values measured on discrete samples.
