Marine Investigations for safe & reliable inshore and offshore operations

Fathom's commercial diving operations are conducted by OSHA 1910.440-compliant, certified commercial divers with capabilities across infrastructure inspection, marine construction support, and underwater hazardous material operations. Our teams perform PE-supported structural assessments, DOT operator-qualified pipeline inspections, mooring system installation and repair, and ultrasonic thickness testing. All scope is executed by Fathom employees, with no subcontracting of critical work.

Fathom deploys scientifically trained divers with biological sciences degrees to conduct underwater data collection in freshwater and marine environments. Services include submerged aquatic vegetation surveys, shellfish resource assessments, fish species identification, and biological sample collection in support of permitting, environmental impact assessments, and resource management programs.

Fathom delivers USCG-accepted marine safety instruction through Alaska Marine Safety Education Association-certified trainers, covering cold-water survival procedures, safety equipment deployment, and onboard drill execution under scenario-based conditions. Programs serve commercial fishing operations, private contractors, and government agencies, structured to meet client-specific HSE requirements.

As a NOAA-approved service provider for the At-Sea Monitor Groundfish Observer Program and the Industry Funded Scallop Program, Fathom has managed observer deployments since 2011, accumulating tens of thousands days at-sea completing data collection. Our full-time, regionally based observers collect biological catch data, monitor bycatch, and document protected species interactions throughout the Northeast and Mid-Atlantic.

Fathom provides NOAA Fisheries-approved electronic monitoring services for commercial fishing vessels participating in Northeast groundfish program. Our in-house EM reviewers conduct video review and data annotation in accordance with program-specific requirements, managing all aspects from Vessel Monitoring Plan development through compliant data submission to NOAA. All data is handled under strict chain-of-custody protocols.

Fathom fields NMFS-approved Protected Species Observers for offshore and nearshore projects to include wind farms, dredging, pile driving, and marine construction projects subject to BOEM, USACE, and USFW permit requirements. Our PSOs follow the marine mammal monitoring plans to conduct real-time visual monitoring, document detections with geo-referenced coordinates, and implement required mitigation measures including work stoppages and exclusion zone enforcement.

Fathom conducts field-based environmental surveys to characterize marine and coastal habitats in support of pre-construction baseline assessments, NEPA documentation, and regulatory permitting. Capabilities include benthic habitat characterization, sediment and water quality sampling, submerged aquatic vegetation mapping, turbidity profiling, and invasive species assessment. Data are delivered in formats accepted by USACE, EPA, BOEM, and state environmental agencies.

Fathom provides ongoing environmental monitoring for construction, dredging, offshore energy, and coastal infrastructure projects operating under active environmental permits. Services include turbidity monitoring, hydroacoustic monitoring, water quality parameter tracking, and habitat impact documentation, conducted under client and agency-approved monitoring plans to generate defensible field records at project closeout.

Fathom owns and operates a fleet of trailerable coastal support vessels ranging from 14 to 28 feet, captained by USCG-licensed operators with experience across the full range of Fathom's field programs. Vessels are maintained to year-round operational readiness for diving operations, observer deployments, environmental surveys, and monitoring assignments, without third-party coordination delays.
