Ocean

The ocean covers 71 percent of the Earth's surface and contains 97 percent of the planet's water, yet more than 95 percent of the underwater world remains unexplored. The ocean and lakes play an integral role in many of the Earth's systems including climate and weather.

One of every six jobs in the United States is marine-related and over one-third of the U.S. Gross National Product originates in coastal areas. The ocean is key to transportation, recreation and its resources may hold the cures to many diseases.

NOAA protects, preserves, manages and enhances the resources found in 3.5 million square miles of coastal and deep ocean waters. NOAA's National Ocean Service provides products, services and information that promote safe navigation, support coastal communities, sustain marine ecosystems, and mitigate coastal hazards.
