Product Info

GeoPulse 2 is a next-generation, high-power sub-bottom profiler designed for demanding offshore and deep-water surveys. Featuring programmable waveforms (CW, Chirp, Ricker) and output power up to 10 kW, it delivers excellent sediment penetration and detailed stratigraphic imaging. Ideal for geological studies, offshore wind, pipeline routes, and infrastructure assessments where deep penetration and flexibility are essential.

The GeoPulse Compact Over-The-Side (OTS) is a lightweight, portable SBP optimised for rapid deployment from small vessels. It provides high-resolution sub-seabed imaging with penetration up to ~80 m in fine sediments while maintaining low power requirements. Well suited to rivers, lakes, estuaries, nearshore surveys, and rapid-response environmental or dredging projects.

The TOPAS range comprises advanced parametric sub-bottom profilers delivering very high spatial resolution with excellent penetration in medium to deep water. Using nonlinear acoustic principles, TOPAS systems are ideal for specialised applications requiring exceptional detail, such as offshore engineering, geohazard assessment, and scientific research.

Key Features

1. Deep Sub-Seabed Penetration: Images sediment layers and buried objects up to ~80 m below the seabed, depending on conditions.

2. Wide Frequency Coverage: Multiple frequency bands allow optimisation for penetration depth or fine resolution.

3. Flexible Deployment Options: Hull-mounted and over-the-side configurations support vessels of all sizes.

4. Survey-Ready Integration: Compatible with industry-standard SBP software for acquisition, interpretation, and export to GIS/SEG-Y workflows.
