Marine and fresh waterways are unique natural environments for marine flora and fauna, and are critical assets to commerce, industry and recreation. Maintaining and managing these crucial resources requires an understanding of their conditions, uses, and influences on both natural and man-made environments.
DEA Marine Services has the experience and technical resources necessary to support environmental investigations, document and monitor conditions using current and historic data, and aid in the remediation of contaminated marine sites.
Environmental investigations cover a broad range of hydrographic, oceanographic, marine geophysical and associated geospatial services. Instrumentation and methodology are customized to meet specific project needs. Environmental investigations typically support:
- Remedial Investigations (RI);
- Feasibility Studies (FS);
- habitat mapping (macrophytes, currents, tidal range, bathymetry and substrate material);
- sediment cap construction and monitoring;
- sediment transport studies;
- inundation modeling;
- derelict fishing gear remediation;
- unexploded ordnance remediation;
- marine archaeological investigations;
- tide and current studies;
- acoustic noise compliance monitoring during construction; and
- baseline condition mapping and analysis.
