PROJECT DESCRIPTION:
This project is a multi-disciplinary project (science and engineering technology) which contributes to better understanding of the marine hydrothermal system at volcanic arc zones of the European marginal seas. Investigations are based on 1) the knowledge we have obtained in the last years about hydrothermal systems; 2) the deep-towed instrument OFOS (ocean floor observation system), 3) sensor packages which were partly developed for downhole chemical measurements. Investigations are concentrated on hydrothermal plumes as indicators for hydrothermal mineral forming processes in relation to the tectonic setting of the Aegean arc and other potential sites in the Mediterranean Sea. Promising areas will be identified from seismicity, seafloor topography and magnetic anomaly surveys. This will be followed by the search for a hydrothermal plume produced by an active vent field. The significant chemical signal of the plume will be identified by on-line in-situ measurement of temperature, particle density, H2S, Mn, Fe, Zn, Pb. Output from the sensors will be linked to navigational information to produce a map of the plume. These measurements will be done under video observation as the whole system will be linked to the OFOS.
