NOAA’s National Ocean Service:
Working for you!

NOAA’s National Ocean Service (NOS) has a unique mission that includes some of the most interesting parts of government! NOS is America’s leader in coastal and ocean science, technology, and management. We balance economic and environmental needs and deliver tools and services that directly support national security and the public. Dive in to learn more about how NOS works for you each and every day.

We make using GPS more accurate. Our science improves GPS data by providing positioning information that is accurate to a fraction of an inch. This ensures ships navigate safely under bridges; farmers efficiently apply fertilizer to crops; and construction occurs in exactly the right place and with precise engineering.

We help to get ships — and their cargo — safely and efficiently across oceans and into ports. Our science plays a key role in ensuring that shipments move swiftly along our marine highways. Who doesn’t like a new pair of sneakers? How about fresh bananas? Almost everything we use, wear, and eat relies upon our ports operating safely and efficiently.

• We make nautical charts, the roadmaps of the ocean, so those on the water can avoid dangers and arrive safely at their destination. We’ve been doing this since President Thomas Jefferson first commissioned a survey of U.S. coasts in 1807!

• We provide real-time water level, current, and wind conditions along shipping routes, helping mariners navigate busy, narrow channels, and ensuring successful delivery of cargo. Our “air gap” sensors also tell vessel operators if their ships can safely fit under bridges.

We respond when disasters strike. From extreme weather events to oil spills, our emergency response teams spring into action to assess impacts and aid in recovery.

• Following hurricanes and natural disasters, our scientists take flight aboard NOAA planes that collect aerial images of damage. The imagery is critical to understanding impacts sustained to both property and the environment and supports safe navigation during maritime recovery efforts. We also work to survey for dangers to navigation and remove marine debris to reopen ports and waterways.

• Every year we respond to over 150 oil and chemical spills in U.S. waters — which can threaten life, property, and substantially disrupt marine transportation with widespread economic impacts. Following a spill, our teams provide scientific support to estimate where the spill may go; analyze potential hazards; and to assess the risks and evaluate damages to people, habitats, and other species.

We forecast future ocean conditions and hazardous events. Our online tools help the public protect their health, safety, and wellbeing while at home and on the water, and our rip current forecasts keep swimmers safe while enjoying the ocean.

• We help to protect critical coastal infrastructure from hazardous events, like high tide flooding and tsunamis. We also maintain a national network of tide gauges, and gather and connect thousands of coastal and ocean data sources from around the country that inform NOAA forecasting tools for public safety and grow the ocean economy by improving public access to foundational data and information.

• Did you know that harmful algal blooms can occur in every U.S. coastal and Great Lakes state and can affect the health of people, animals, and even contaminate drinking water? We produce forecasts in the Gulf of America, the Gulf of Maine, and Lake Erie so beach-goers can adjust their plans; health officials and water treatment facility operators can focus their testing procedures; and seafood and tourism industries can minimize impacts to their businesses; and the public can remain healthy and well.

We take care of special coastal and ocean places. By conserving unique areas around the country, we’re also boosting the economic benefits nationwide.

• We work with partners to manage 18 National Marine Sanctuaries and 30 National Estuarine Research Reserves in U.S. waters and along the coastline. These protected places provide opportunities for recreation and tourism — like fishing, diving, and whale watching — attracting visitors from all over the world and fueling local economies. As world-class destinations, these places also help raise public awareness about research and conservation.

• Did you know that coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and are also a source of food and new medicines? We work to protect, conserve, and restore the nation's coral reefs for current and future generations.

These are just a few of the many ways NOS helps protect Americans and our oceans and coasts. Visit our website to learn more about how we contribute to NOAA’s mission of science, service, and stewardship.
