Thousands of gallons of oil seep from fissures in the seafloor come to the surface each day just off the coast of Santa Barbara, California. This isn't a disaster zone, though: it's one of the world's largest naturally occurring oil seeps, and it's been active for thousands of years. Because of the consistency of these seeps, scientists can use the area as a natural laboratory. It is an incredible place to develop oil thickness characterization applications, oil extent geospatial mapping analytics, and operational automated oil spill detection.
Recently, a research team collaborated to test remote sensing technology for use in oil spill response. They utilized a radar instrument, referred to as UAVSAR. It helped them characterize the thickness of the oil within an oil slick. This thicker oil is disadvantageous to the environment as it stays there longer and damages marine life more than thin oil. They utilized remote sensing data to determine where oil spills and their thickest parts are located. The research would be an outstanding contribution to Water Pollution Treatment Market as it answers one of the critical mysteries to direct response and remediation activities related to oil spills.
The team is a pioneer in identifying and tracking coastal oil spills. They just finished a fall field campaign in Santa Barbara. UAVSAR is a system developed by ASA. It attaches itself to the fuselage of an airplane that collects pictures of the oil spill location.
On the other hand, SAR images are not like those obtained from conventional sensors. The gadget sends down radar pulses to the ocean's surface. The signals that bounce back are then utilized to determine roughness at the ocean's surface caused by waves. When oil is present, it dampens the waves, resulting in smoother water sections. In SAR images, these smooth, oily regions appear darker than the surrounding clean water — the heavier the oil, the darker the area.
The scientists must next corroborate the aircraft observations by going to the same location on a boat and measuring the thickness of the oil by hand.
While UAVSAR's oil spill thickness detecting capabilities are beneficial, flying an aeroplane over every oil slick is impractical. As a result, once the data from the spring and autumn field trials has been validated, it will be employed to train algorithms that automatically compute oil thickness from SAR data.
