.. Goals ..
. diagram of ship towing CTD over plume . To develop methods for locating and mapping distributions of hydrothermal plumes and hydrothermal venting systems. .
. diagram of temperature plumes after a hydrothermal event . To monitor the variability and evolution of hydrothermal systems, especially in response to volcanic events. .
. diagram of the global  mid-ocean ridge system . To investigate realtionships among hydrothermal, magmatic and tectonic processes along the global mid-ocean ridge system. ..
