A technique facilitates detection of gaseous emissions in a marine environment via a vessel or vessels traversing a region of the marine environment. Environmental data is collected via a detection system on each vessel and communicated to a processing system. The processing system processes various environmental data such as location data, emission detection data, wind data, and/or other data to determine an emissions result. This emissions result is output in a form to facilitate decision-making with respect to potential corrective actions to reduce the gaseous emissions.

A Data Transmitting Marine Vessel System (DRTMEVS) that deploys and provisions the operation of both an aerial visual and data collection drone and an underwater camera and data collection system ROV to gather data at, above, and below the surface of the water simultaneously or individually, or in multiples. The vessel having geodetic and GPS guidance systems that determine the course and actions of the crafts either in a pre-programmed autonomous mode or from a remote operator. The control of the three separate remotely controlled data collection systems and craft are consolidated in the form of a vessel of (DRTMEVS) and monitored via a multitude of possible signals anywhere in the world from a control center.

In some examples, an unmanned marine surface vessel connected to a three-dimensional array of sensors positioned are deployed in proximity with an obstruction area of a survey environment. The three-dimensional array of sensors positioned in proximity with the obstruction area of the survey environment records signals that are affected by a target structure.

The present invention relates to profiler systems and methods for observing and sensing aspects of a body of water at a plurality of depths. A water profiler is disclosed comprising, generally, a vessel body connected to an external mooring mechanism via an attachment mechanism, a drive mechanism for maneuvering the vessel body longitudinally about the mooring mechanism; an articulating mechanism; and a sensor array capable of measuring a parameter for study wherein the vessel body is capable of articulating about the mooring mechanism. In alternate embodiments, the articulation allows the vessel body to be placed in relation with the three dimensional current such that at least one sensor is positioned into the current so as to sample or measure undisturbed water. In alternate embodiments, hydrofoils or wings are mounted to the vessel body that can be manipulated to harness the current force and maneuver the vessel body.
