Magnetometer Surveying

Specializing in environmental research, mapping, and reporting, AFFILIATED RESEARCHERS utilizes advanced geophysical instruments and software to provide magnetometer surveying of lakes, harbors, rivers, canals, estuaries, and marine environments.

Magnetometer surveying can be a highly effective method in identifying and locating surface and sub-surface utilities or ferrous debris in aquatic or marine environments. This effective method can provide accurate GPS locations of the utilities or debris to enable avoid or removal these objects prior to dredging or intrusive activities.

AFFILIATED RESEARCHERS utilizes a Geometrics G882 marine magnetometer to conduct magnetometer surveys. Magnetometer survey tracks are developed using hydrographic-geophysical software, at sufficient intervals to ensure coverage of the project area and detection of utility crossings and debris. The magnetometer survey is conducted using a survey-grade GPS, in a client-specified coordinate system, with all GPS-coded data recorded onto an onboard hydrographic computer.

The collected data are initially compiled and reviewed by the onsite Project Geophysicist to verify project coverage. Final compiling of the magnetometer data includes an accurate geospatial survey drawing depicting identified magnetic biases found at the project. Our magnetometer survey deliverables include geo-referenced backgrounds such as orthographic aerial photographs, engineering plans, land surveys, and other databases to show information relevant to the project.

AFFILIATED RESEARCHERS uses the most advanced hydrographic and mapping software produced by the industry’s leaders to include: Caris; QINSy; HYPACK; POSPac MMS; SonarPro; Trimble; ESRI; and AutoCAD. Our developed hydrographic products are readily exported into GeoTIFF, JPEG, PDF, CAD, or GIS formats to enable convenient data sharing.

AFFILIATED RESEARCHERS provides its magnetometer surveying services nationwide and throughout the US territories. Please call us to discuss your project requirements.
