About Us

Geodynamics was founded by university researchers in marine geology, coastal science and remote sensing with a simple business model in mind:  Using cutting edge technologies and highly qualified staff, we provide meticulous data products to support our clients’ multi-disciplinary needs.  We remain narrowly focused within our area of expertise, and have spent decades developing specialized workflows, investing in evolving survey technologies, and building a team of dedicated and experienced scientists.

Our success is rooted in our people—enthusiastic problem solvers with a passion for marine remote sensing, survey, and the science behind it.  Geodynamics’ progressive “Always Learning” culture empowers team members to pursue advanced training, certifications and licensure, and our “Team First” structure advances our collective knowledge through cross-training and mentorship between junior and senior staff.  These principles create a company ethos dedicated to scientific improvement, which translates into greater overall survey accuracy and efficiency through continuous internal research and development.

A focused area of expertise.  A culture that promotes excellence.  This is what keeps Geodynamics at the forefront of our field with a growing base of long-term clients.

Christopher W. Freeman, PLS


About Us

As co-founder and President of Geodynamics LLC, Chris Freeman has managed coastal and nearshore studies throughout the Mid- and South Atlantic region, including high-resolution hydrographic mapping for sediment transport modeling, coastal change analyses and habitat classification, inlet and headland-related tidal hydrodynamics, and the quantification of shoreline processes through 4D shoreline change analyses. A licensed NC Professional Land Surveyor, he provides technical oversight and project management for all hydrographic, underwater geophysical, and topographic survey projects, using multibeam, singlebeam, magnetometer, sidescan and sub-bottom sonar and 3-dimensional beach and nearshore mapping techniques using RTK-GPS, mobile laser scanning and topographic survey techniques. Chris has been actively involved in The Hydrographic Society of America’s Student-Mentor program for several years, and is committed to expanding opportunities for students in hydrography.
