Profile: Hydroscience Technologies, Inc. specializes in offering data recording systems, digital array, digitizing modules and acoustic streamer. NTRS2 QAI is a lightweight, portable recording system that can manage multiple streamers. An onboard system for large seismic vessels that can manage an unlimited number of streamers is also available. Its application includes marine seismic 2D/3D, high resolution 3D seismic, ocean bottom cable, reservoir monitoring and drag cable. The SeaTRAK® and SeaMAX® modules are powered via a 1.2A DC constant current loop, which allows small gauge wires to be used, reducing the size of the wire bundle. The module's 12 analog inputs are sampled at 1/2, 1, 2, or 4ms via 24bit delta sigma converters. Digitized data are sent to the recording system via a telemetry system comprised of twisted pairs. Power, control, diagnosis, and acquisition are performed via the NTRS2 recording system on the recording vessel / platform.
