Marine Spatial Data Solutions for Your Toughest Challenges

For years, we've delivered a diverse range of geophysical and geospatial surveys in the marine environment. We specialise in helping our clients attain precise spatial data collection. Tell us about your challenges, and we'll help you find the perfect solution.

Our growing team has extensive in-house experience in nearshore and offshore environments. We can operate from our own dedicated survey vessel, MV Flatholm, or work seamlessly from suitable third-party vessels, whatever best fits your project needs.

Tailored Marine Surveys

At CMS GeoScience, we don't believe that one-size-fits-all. We offer a customer-designed service, from simple vessel charter to comprehensive marine geophysical surveys. We combine our core equipment with specific hired-in equipment to meet your exact requirements. Get a solution tailored to your project, not constrained by standard packages.

We excel at finding unique solutions for even the trickiest and most unusual survey scenarios. Our agile and inventive approach helps us solve your data collection problems. Whether you need bathymetry, habitat mapping, sub-surface imaging, oceanographic data, or anything else, we're ready to listen and develop the right solution for you.

Unlocking Efficiency: Geophysical & Geotechnical Integration

Combining the geophysical and geotechnical strengths of CMS GeoScience is a winning formula, especially when achieved from a single vessel. This approach offers significant savings by avoiding multiple vessel mobilisations. For instance, the MV FlatHolm has successfully performed vibrocoring, ROV inspection, cable burial depth surveys, and MBES Bathymetry seamlessly on a single project, proving true project efficiency.
