Abstract
Described herein are systems and methods for determining the location, composition and concentration of a hydrocarbon containing plume in environmental seawater. These systems and methods disclosed use multiple complex admittance measurements from seawater in order to identify the contents, concentration, and location of the hydrocarbon containing plume. In preferred variations system includes a sensor array that substantially simultaneously records plume location, depth, and composition.
