In order to compute absolutely correct wet bulk densities from calibrated porosity logs a grain density must be assumed. For most terrigenous and calcareous sediment cores this parameter is not very critical as it often only changes by few percent downcore (e.g. 2.6 - 2.7 g cm ). However, in cores from the Antarctic Polar Frontal Zone where...

Assume that you have recovered a sediment core in the Antarctic Ocean close to the Polar Frontal Zone. The core is composed of an interlayering of calcareous and siliceous sediments. You would like to determine the downcore porosity and wet bulk density logs by electrical resitivity measurements. What do you have to consider during conversion of porosities to wet bulk densities ...
