The BATHY-2000P is
a CHIRP sub-bottom profiling system providing 8 cm resolution of sediment strata
with bottom penetration to 75 meters. It is designed for applications in rivers, harbors,
and coastal waters and performs to depths of 6,000 meters. An optional amplifier enables
the system to sound to full ocean depth.
-
- An optional tow fish/transducer array allows the system to be easily transported between
ships-of-opportunity in support of pipeline routing surveys, engineering evaluations for
construction sites, pre- and post-dredging volumetric / material classification
surveys, and scientific studies of sediment types.
