CSA Ocean Sciences

What CSA Ocean Sciences does

CSA Ocean Sciences Inc. is a marine environmental consulting firm founded in 1970 and headquartered in Stuart, Florida. The company delivers multidisciplinary marine science services across the full project lifecycle — from baseline environmental impact assessments, permitting, and coastal habitat characterization through ongoing offshore monitoring, protected species mitigation, and emergency response (including oil spill preparedness). Its offerings are organized into twelve core service lines (coastal habitat characterization, impact assessments, offshore characterization and monitoring, oil spill response, protected species monitoring, geophysical and positioning, marine operations, metocean, ocean sound, offshore geotechnical, permitting, and sediment profile imaging) supported by technical resource divisions — Environmental Data and Geospatial Services (EDGS), a research vessel fleet, autonomous underwater and surface vehicles, modeling, and library services.

The business model is professional-services consulting: revenue is generated through project-based engagements priced per scope, duration, and technical requirements, typically under multi-year contracts. CSA is a member of the Esri Partner Network and integrates ArcGIS-based geospatial deliverables, including Common Operating Picture web maps, into client engagements. Customer segments are organized across offshore energy (oil and gas, renewables, carbon capture and sequestration), government and defense (U.S. Navy, federal agencies, international and local government), and infrastructure and natural resources (marine mining, ports, submarine cables). The company operates a wholly owned subsidiary in Trinidad and Tobago and acquired Morgan & Eklund to add hydrographic survey capabilities.

In February 2026, CSA was acquired by UK-based APEM Group (part of Applus+), transferring 115 employees and establishing a major US operational hub. The deal opens new geographic markets (Africa, Brazil, Western Australia, Caribbean, Middle East) and integrates CSA into a larger environmental and scientific advisory platform while preserving the CSA brand.

Direct peers

• APEM Group: UK-based marine and freshwater environmental consultancy that acquired CSA in Feb 2026. Operates the same core scientific consulting model across offshore energy, renewables, and infrastructure, and serves as CSA's direct parent and integration partner.
• Anchor QEA: US environmental and engineering consulting firm with deep coastal, marine, and water resources expertise. Comparable in size, federal contracting orientation, and service mix (EIAs, permitting, habitat restoration).
• SLR Consulting: Mid-size global environmental and advisory consultancy covering EIA, permitting, marine science, and infrastructure. Comparable specialty-consulting model with multi-region delivery.
• RPS Group: Specialist environmental, marine, and water consultancy (now operating under Tetra Tech post-acquisition) that delivers offshore permitting, survey, and EIA services to energy and infrastructure clients with a model closely comparable to CSA.

Broad incumbents

• ERM (Environmental Resources Management): Largest pure-play global environmental consultancy. Overlaps with CSA on offshore EIAs, permitting, and impact assessment but operates at materially larger scale and broader portfolio.
• Tetra Tech: Specialty consulting and engineering firm with a large environment, water, and offshore energy practice. Competes for the same federal, offshore energy, and infrastructure environmental scopes as CSA but at much larger scale.
• AECOM: Global E&C firm with a significant Environment and Marine practice. Competes for large offshore energy, defense, and infrastructure EIAs where CSA also bids, often as a bundled-services alternative.
• Stantec: Global design and environmental consultancy with marine and coastal capabilities (built out via the Cardno acquisition). Competes with CSA on port/coastal and federal environmental work.
• Ramboll: Denmark-rooted global engineering and environment consultancy. Comparable marine/coastal and offshore renewables EIA work, serving many of the same European and international oil & gas clients as CSA.
• Fugro: Global offshore survey and geotechnical specialist operating a similar fleet and AUV/USV technology stack. Overlaps with CSA on geophysical, geotechnical, and hydrographic offshore surveys but at much larger fleet scale.
