NOAA’s National Ocean Service
America’s leader in coastal and ocean science, technology, and management.
Abandoned and derelict vessels leach pollutants into marine ecosystems, endanger boaters, and block vital waterways. With NOS’s support, communities throughout the Gulf Coast are coming together to clean up their local waters.
Oil spills are a race against time and every second matters. To accelerate the response to oil spills and other disasters, NOS has partnered with the U.S. Coast Guard to launch new drones that will serve as a powerful new tool for environmental protection.
The Director of the Office of Coast Survey leads NOAA’s ocean mapping and nautical charting program, which includes surveying the seafloor, developing navigation products, services, and data-driven models, and reopening ports and waterways following disasters.
This current meter system took one of NOAA’s predecessor agencies, the U.S. Coast and Geodetic Survey, from manual to automatic instrumentation data collection, advancing both physical oceanography and marine navigation technologies.
The 2025 hurricane season has officially concluded, and NOS teams were there every step of the way, helping on the ground, from the sea, and in the clouds.
Real-time data from NOAA’s tide gauges enables the quick detection of changing water levels caused by tsunamis. This improves the accuracy of forecasts and allows emergency managers and communities to make informed decisions and take life-saving measures with confidence.
