Electrical conductivity measurements (ECM) of the core is a very rapid methodto indicate how acidic the core is without the chemical detail of the ionanalyses. The value of the measurement is that it can be done for the wholelength of the core in high resolution and provide an immediate picture of thecore and allow quick detection of interesting areas, such as a volcaniceruptions. Because it is a high resolution, continuous measurement it can beused, along with the other measurements, for time frequency analysis in orderto identify cycles in the climate signal.
