White Paper: Acoustic Detection of Subsurface Oil

ASL Environmental Sciences, a technology specialist with over 40 years’ experience in oceanographic, acoustic, remote sensing and ice research product, has released a white paper on acoustic detection of subsurface oil.

Marine sensitivities to hydrocarbon pollutants pose serious impediments to offshore hydrocarbon production-related activities. Autonomous underwater vehicles or ship-towed bodies are a means of combining the long-range detection capabilities of acoustics, with the identification ability of point sensors.

The AZFP is a multiple-frequency, calibrated scientific echosounder, with low power consumption, making it well-suited to operation on autonomous vehicles. A recent experiment in a large test tank using an AZFP with 4 high-frequency channels (455, 769, 1250 and 2000 kHz) has shown that subsurface oil is detectable with the AZFP.
