Welcome to the new Office of Coast Survey homepage! We
welcome feedback, and still have the
previous version available for a limited time.
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.
