Steele Associates performs high-resolution sub-bottom geophysical surveys using a vessel mounted parametric sub-bottom profiler. This system operates in multi-frequency mode for a small acoustic footprint, high ping rate, and no ringing or side lobes for the highest possible horizontal and vertical resolution. The pole-mounted configuration allows for greater accuracy in locating reflectors. While acoustic penetration is never certain, we have experienced great success with this unit over a spectrum of site conditions. Data are processed, analyzed and interpreted by a Senior Marine Geophysicist.
