Oil Spill Monitoring

A Proven Solution to Detect and Monitor Oil Pollution at Sea

Accidental or from illegal discharge, oil spills require rapid response to avoid massive spread at sea and mitigate dramatic impacts on marine environments.

CLS helps you detect and identify oil spills, calculate their drifts and potential polluters for immediate response, monitoring and support contingencies.

Radar satellite imagery, a proven technology to identify oil slicks

Dedicated interface for analysis, drift modelling and polluter identification

The MAR-GE/T floatable beacon for in-situ pollution tracking

Radar Satellite Imagery
for Accurate Identification

We acquire, process, and interpret SAR imagery to detect and classify accidental or intentional oil spill.

Satellite radar images are a proven technology for oil spill detection offering coverage over large areas. This technology is especially efficient in detecting pollution in all weather conditions, day or night.

We offer best revisit rate relying on main radar satellite constellations available, and near real-time capacity through CLS’ direct receiving stations.

In-Depth Analysis
for Timely Operational Response

Decision makers and responders are granted with powerful insights to conduct operational response: location and size of the oil slick, near real-time calculation of the drift and identification of the potential polluter for prosecution.

Visualise all the information you need through our MAS platform.

MARGE/T
Floatable Drifter for In-Situ Pollution Tracking

Simply place the MAR-GE/T beacon on the surface of the oil slick and let it drift for in-situ measurement and monitoring of the pollution, as it is equipped with a GPS data logger reporting up to 96 daily accurate positions.

This easy-to-use drifting floatable beacon provides global satellite coverage and geofencing services through the Argos satellites network.
