Abstract
A study has been made of the mass physical properties and electrical resistivity of marine sediments. The well‐known linear correlation of density with porosity was confirmed. A third‐degree polynomial curve was found to be the best fit for our data relating porosity and the formation factor, which is the ratio of the bulk resistivity of marine sediments, to the resistivity of interstitial water. An electrical resistivity probe has been devised to obtain “in‐situ” profiles of resistivity versus depth. The instrument is 13 m long and weighs 700 kg in water. About thirty rapid measurements on the sea floor can be made in one lowering. Good correlation was obtained between electrical probe measurements and direct porosity measurements made on cores taken nearby.
