full fathom five marine services

Full Fathom Five offers multiple services that assist our clients with the NEPA/NHPA Section 106 process and other forms of environmental review. All of our services deploy cutting-edge methodologies to give our clients an edge so that they can successfully complete their projects on time and on budget.

High-resolution geophysical (HRG) data review interpretation for all aquatic contexts, including marine, estuarine, fluvial, and lacustrine.
This includes all types of sub-bottom profilers, side scan sonar, multibeam echosounder, and magnetometry/transverse gradiometry. Data review focuses on the ground model developed by our clients to facilitate a paleo-landscape reconstruction of formerly terrestrial, now submerged surfaces. This ground model is used to identify three characteristics within the sub-surface landscape: first, areas where landforms favorable to human occupation were; second, where they are preserved; and third, where they are now eroded. Full Fathom Five uses this approach to help our clients satisfy environmental reviews without incurring unnecessary expenses.
Geotechnical core review and interpretation for all aquatic contexts, including marine, estuarine, fluvial, and lacustrine.​

Full Fathom Five offers assistance with geotechnical components of a project throughout its life cycle from geotechnical core clearances to interpretation and synthesis with seismic datasets. Our services focus on correlating sedimentological findings from geotechnical cores to potentially preserved landform signatures in seismic datasets. This allows Full Fathom Five to better identify and characterize formerly terrestrial landscapes to support environmental review processes.

One unique service we offer is that we come to you (or your geotechnical experts) to evaluate geotechnical and geoarchaeological cores alongside them if desired. Contact us for more details.

Geoarchaeological analysis for potentially preserved landforms and archaeological materials.​
Full Fathom Five specializes in multiple types of geoarchaeological methods to test sediments recovered from submerged contexts for archaeological materials. These include landscape reconstruction using sedimentological findings, particle size analysis, and micro-debitage analysis.
Desktop research for environmental contexts including the most recent geological and geomorphological scientific literature drawn from peer-reviewed works.​
Environmental contexts comprise both Quaternary geology and geomorphology as well as paleoclimate for relevant periods to assist in predictive modeling for potentially inhabited portions of the now-submerged landscape.
Desktop research for cultural contexts also incorporates the most recent literature drawn from peer-reviewed archaeological and anthropological literature.​

Many cultural resource management consultants maintain databases of cultural contexts for inclusion in their reports, but far too many of them fail to regularly update these critical research components. FFF tailors our cultural studies to the needs of each project and client. This ensures that the most current research is included for properly evaluating the potential for impacts on cultural resources in a project area. Contact us for more details.
