Geophysical Surveys

CR has conducted over 300 marine and freshwater multiparameter geophysical surveys in support of engineering, archaeological, environmental remediation, and marine construction projects. Most projects are designed to facilitate simultaneous acquisition of high-resolution bathymetry and data from other instruments (sub-bottom sonar, magnetics, side scan). We maintain a comprehensive pool of remote sensing and navigation systems, including sub-bottom profilers, side scan sonar systems, magnetometers, acoustic Doppler current profilers, and DGPS/RTK DGPS units.

Our data processing and interpretation strategies are based on a synergistic combination of our extensive experience with GIS, CAD and specialized software processing capabilities. All data products are ESRI GIS and CAD compatible. We also offer processing and analysis services for geophysical and hydrographic data collected by other parties.
