Company Overview

Geo-Resources initiatives in the field of GPS satellite technology have provided government and private industry with horizontal and vertical control for topographical and photogrammetric mapping. Advanced bathymetric surveys using sophisticated multibeam swath echo sounders, heave, roll and pitch sensors, automated hydrographic data acquisition and processing systems is further evidence of GRI's commitment to excellence. Moreover, GRI was the leading contractor involved with the development of a Canadian Ocean Mapping System for the domestic and export service.

This system, which is one of the most technologically advanced ocean mapping systems in the world, consists of a Canadian-built Remote Controlled Vehicle called DOLPHIN (Deep Ocean Logging Platform with Hydrographic Instrumentation and Navigation) equipped with differential GPS technology for precise navigation and positioning, and integrated with the Simrad EM100 Multibeam Sounding System that can sweep the ocean floor to depths of up to 600 metres, providing total bottom coverage. A Specialized Handling System designed and developed in Canada, can safely launch and recover the DOLPHIN in sea state 5, thereby extending the sea time operations to the maximum, hence adding to its cost effectiveness.

DOLPHIN is a diesel-powered seven metre long torpedo shaped vehicle which runs four metres below the ocean's surface at speeds of up to 14 knots, with only a mast and antenna showing above the sea surface. Using the DOLPHIN Multibeam System there is no longer the requirement for a specialized ship, and bottom coverage increases to 100 percent. Consequently, the multibeam system with its wide swath technique can collect more bathymetric data than a conventional single beam system and several times faster.

With the DOLPHIN/EM100 Ocean Mapping System, GRI can complete surveys several times more quickly than using the conventional single beam system and yet requiring up to one-third the number of personnel, thereby achieving significant cost reduction for surveys and map production. Furthermore, the sheer volume and consistency of data which is collected and processed in digital form makes it possible to produce maps and data sets with an accuracy and resolution which have never before been achievable. Typical applications for the DOLPHIN System include, pipeline route surveys, harbour entrance surveys, offshore oil and gas site surveys, hydrographic surveys of exclusive economic zones, fisheries seabed mapping and other coastal and ocean resource mapping projects.

Geo-Resources Inc. has provided ocean mapping services to the United States Department of the Navy near Norfolk, Virginia, and is actively pursuing similar projects in Canada and South East Asia. The company is teaming with Canadian, U. K. and other European interests in providing one of its three DOLPHIN's and expertise to determine the feasibility of the DOLPHIN as a scientific platform for fish stock assessment surveys.
