Innomar "deep-36" Sub-Bottom Profiler

High-Resolution Acoustic Imaging Down to 6,000 Meters

Product Overview

The Innomar deep-36 is the premier choice for offshore surveys requiring high-resolution sub-seabed data in water depths ranging from 5 to 6,000 meters. Bridging the gap between shelf-zone systems and full-ocean depth profilers, it offers the perfect balance of portability, power, and precision for deep-sea operations.

Utilizing parametric acoustic technology, the deep-36 generates a highly directional sound beam with no distinct side lobes. This allows for superior lateral resolution and the ability to detect small buried objects and fine sediment layers that conventional low-frequency echo sounders often miss. Whether for cable route surveys, geological research, or deep-sea hazard mitigation, the deep-36 ensures reliable data acquisition even in challenging sea states.

Why Choose the Innomar deep-36?

  • Optimized for Deep Operations: Delivers consistent performance down to 6,000m with a penetration capability of up to 150 meters into the seabed.
  • Superior Stability: Available in a "Basic" version (Heave/Roll compensation) and an "RP" version (Heave/Roll/Pitch compensation) to ensure artifact-free data in rough seas.
  • Flexible Integration: Acquires full-waveform data in Innomar RAW format, easily convertible to industry-standard SEG-Y and XTF for seamless post-processing in third-party seismic software.

  • Multi-Ping Mode: Supports burst pinging rates up to 40 pings/second, maintaining high data density and spatial resolution even at significant water depths.
  • Active Beam Stabilization: Electronic beam steering counteracts vessel movement (Roll/Pitch) to keep the acoustic footprint focused on the target area.
  • Versatile Pulse Options: Select between CW, Ricker, and FM Chirp pulses to optimize for resolution or penetration depending on sediment type.
  • Deep Water Reliability: Rugged transducer design and high source level (>246 dB) ensure strong signal return from deep-sea floors.
  • User-Friendly Control: Operated via the established SESWIN software, featuring remote control capabilities via Ethernet for flexible vessel setups.
