"An ideal subbottom profiler has a broad frequency band, high energy, rapid trigger rate, and highly repeatable source characteristics. These elements provide for maximum vertical and horizontal resolving capacity, subbottom penetration even in hard and gas-bearing sediments, shot-to-shot coherency and phase and amplitude information to facilitate interpretation. In addition, directional source characteristics limit incidental environmental noise. The Geoforce DTS optimizes these characteristics to the physical limits of modern technologies, utilizing two modes of operation: sparker and boomer"--Page [1]. Marine sediments Scotian Shelf.
