Company Profile

ship The Teledyne name in the geophysical industry dates back to the 1960s, when some of our earliest designs for streamer cables, energy sources, and recording systems were put to use aboard seismic research vessels around the world.

Geophysical Instruments carries on this tradition, and has earned a strong reputation in the industry for designing, building, and delivering high-quality, reliable, and durable marine seismic exploration products. Our products are used aboard more than one-third of all commercial seismic research vessels.

We continue our focus on serving the needs of the geophysical industry, but we also eagerly assist non-geophysical organizations in finding solutions to their marine data acquisition needs. Our versatile designs for hydrophones and streamer cables can be easily adapted to a variety of unique applications. Additionally, we offer a variety of specialty products and services that are designed to meet specific needs of customers.

With facilities in both the Houston, Texas, and Gloucester, England, Geophysical Instruments is strategically located to serve worldwide requirements.

Marine Exploration Products
Exploration of the ocean bottoms for petroleum deposits is highly important in meeting the ever-increasing need for energy products. This exploration involves sophisticated research vessels towing arrays of long streamer cables with hundreds of hydrophones. An acoustic impulse generated at the vessel and reflected by the ocean bottom is received by the hydrophones. The collected signals are interpreted by highly complex data processors, with the results being predictions of petroleum deposits.

Geophysical Instruments, a business unit of Teledyne Instruments, is the leading independent supplier of hydrophones and streamer cables for marine exploration. For over three decades, our products have set the industry standard. Marine Product's equipment is used on more than one-third of commercial seismic research vessels throughout the world.

In addition to supplying hydrophones, array cables, and related hardware items, we provide repair services for our own equipment as well as that of other manufacturers. With facilities in both the Houston, Texas, and Gloucester, England, Geophysical Instruments is strategically located to serve worldwide requirements.

Company Overview
What would it take to measure tiny pressure waves in an aquatic environment? Teledyne Geophysical Instruments. We design and manufacture sensor and sensor arrays for subsurface geological structure mapping to identify structures/features likely to contain hydrocarbon deposits; listening for the “signatures” associated with ships and submarines, engineering surveys below the ocean floor to facilitate pipe laying or structure placement and research associated with marine environment.
