Solution Overview

Problem

Current methods for locating and sampling hydrocarbon seeps in marine environments are inefficient and costly, as they rely on manned vessels that are time-consuming and prone to errors due to environmental conditions and the episodic nature of seeps, making it difficult to accurately identify and collect waterborne liquid hydrocarbons.

Innovation Solution

The use of unmanned vehicles (UVs) equipped with remote sensing technology, such as synthetic aperture radar, and sampling modules that can autonomously or remotely operate to identify and collect waterborne liquid hydrocarbon samples, integrating with satellite data for near-real-time guidance and analysis.
