Abstract: Geotechnical exploration in offshore arctic regions relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability. By adding additional sensors to the basic CPT, simultaneous multichannel data acquisition including pore pressure, temperature, and electrical conductivity, has allowed more detailed characterization of in situ conditions than is usually possible. Descriptions of some of these new sensors and typical data obtained with them are presented.
