Environmental Surveys

Our team conducts comprehensive seafloor monitoring, impact assessments, and EPA-compliant reports to support marine environmental regulations.

What We Offer

Our Seafloor Surveys include:

Underwater GPS tracking for precise geolocation of every diver and survey point
Current meters and dissolved oxygen sensors to monitor water conditions in real-time
HD video capture with timestamping and GPS overlays for documentation and reporting
Remote and diver-collected sampling, including core and grab methods
Underwater monuments to enable repeatable monitoring in future survey campaigns
Outfall and pipeline inspections to detect damage, blockages, or illegal discharge

All monitoring services culminate in a formal Environmental Seafloor Monitoring Report,
which includes visuals, data tables, spatial mapping, and recommendations in compliance
with state and federal standards.
