New Radar Technology Helps Responders Target the Most Harmful Marine Oil Spills
When oil spills occur at sea, not all patches are equally dangerous. A collaborative effort between NASA and NOAA, known as the MOST campaign, is testing advanced radar systems to pinpoint the thickest, most environmentally damaging oil, allowing cleanup crews to focus their limited resources where they are needed most.
The Marine Oil Spill Thickness (MOST) campaign represents a strategic partnership involving NASA, NOAA, the United States Coast Guard, and several academic and corporate entities. Led by Principal Investigator Frank Monaldo, the project aims to transition advanced ocean remote sensing research into practical, operational tools for disaster response. By accurately identifying the thickest layers of oil, responders can deploy remediation equipment with greater precision, significantly improving the efficiency of environmental cleanup efforts.
The core of this technology involves the Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR), which is mounted on an airplane. During test flights off the coast of Santa Barbara, California, the radar captures image swaths spanning a 12-mile-wide path above the water. This remote sensing data is then validated through a multi-layered approach: researchers utilize drones equipped for multispectral measurements alongside physical samplers placed directly into the water to provide ground-truth data on oil thickness.
This initiative is supported by a multi-year grant from the NASA Disasters Program. Frank Monaldo, who recently joined the Earth System Science Interdisciplinary Center (ESSIC) at the University of Maryland, brings decades of experience to the project, having previously served as a principal staff physicist at the Johns Hopkins University Applied Physics Laboratory. The ultimate goal of this collaboration is to create a reliable prototype system that can be deployed during real-world emergencies to mitigate the ecological impact of marine oil spills.
The project highlights the importance of integrating satellite and aerial remote sensing with in situ measurements to solve complex environmental challenges. By refining how we measure oil thickness from the air, the MOST campaign provides a critical technological bridge between scientific research and the urgent, real-time requirements of environmental protection and disaster management.
