Navigate with Confidence

Coast Survey's work is foundational to safe navigation in U.S. waters, the flow of goods through U.S. ports, and the resiliency of coastal economies and environments. We survey the seafloor; develop navigation products, services, and data-driven models; and reopen ports and waterways following disasters.
