Problems solved by technology

Additionally, to the extent that oil is transported in seagoing vessels or removed from the earth using offshore oil rigs, oil will periodically spill into the environment, specifically the seas and oceans.
These micro-bubbles form an emulsion in the seawater and can create significant underwater oil plumes.
These plumes can cover significant areas and can have serious consequences for animal and plant life which come in contact the plume.
Present technology, including sonar and turbidity measurements are fraught with problems associated with false positives and false negatives resulting from other factors present in the seawater.

Embodiment Construction

[0072]Described herein are devices, systems, and methods for determining the composition of fluids. The composition typically includes both identity and concentration, and may include the determination of all of the components of the fluid. Many of the devices, systems and methods described herein may allow for essentially simultaneous determination of the concentration and / or identity of all of the components in the fluid. In particular, the systems, methods and devices described herein are admittance spectrographic systems, methods and devices which determine the complex electrical admittance of the fluid under multiple surface conditions (either sequentially or in parallel) and / or at multiple applied frequencies in order to determine characteristic properties that may be used to determine identity and concentration. In some variations, additional measurement or sensing modalities may be used in addition to admittance spectroscopy, including optical, thermal, chemical, etc.

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 12 / 877,306, filed Sep. 8, 2010, which is hereby incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The devices, systems and methods described may be used to determine the identity, concentration, and location of one or more components in an aqueous solution. In particular, described herein, are devices, systems and methods for determining the identity and concentration hydrocarbons or other contaminants in seawater.BACKGROUND OF THE INVENTION[0003]Oil and oil containing compounds occur naturally in the environment. Ground oil seepage exists in many parts of the world including the Gulf of Mexico and off the California coast. Additionally, to the extent that oil is transported in seagoing vessels or removed from the earth using offshore oil rigs, oil will periodically spill into the environment, specifically the seas and oceans. Oil does dissipat...
