Abstract

Laboratory measurements on core samples are commonly used to investigate the physical properties of marine sediments. But sediment properties are altered due to the removal from in-situ pressure and temperature conditions. Therefore, in-situ measurements are preferable. In a research project of Leipzig University and Baltic Sea Research Institute, an Electrical In-Situ Apparatus (ELISA) is developed which allows high resolution measurements of electrical resistivity in soft sediments in a tomografic principle. The instrument will consist of three cylindrical plastic probes (length 3 m) with 25 point-like electrodes (distance 10 cm), which are connected by multicore cables to a multichannel resistivity meter onboard a research vessel (see Fig. 1). First part of the instrument is a single probe with 25 electrodes.
