One more inch of water in a port means larger ships can enter, bringing millions of dollars worth of additional cargo.
And, carrying more goods in one trip means fewer total trips to ship the same amount of stuff. That’s good for the safety of our waterways, it’s good for the environment, and it’s good for your wallet. In this graphic, see about how much cargo a ship can carry -- and what it's worth -- with one more inch of depth in a port.

An Inch of Water. What's it worth? See how deeper ports = larger ships, millions of dollars worth of additional cargo.


Wildlife viewing is a popular recreation activity, but it is important to know how to interact with ocean wildlife so that you can make the right decisions. Irresponsible human behavior can disturb animals, destroy important habitats, and even result in injury to animals and people. NOAA Fisheries and NOAA’s Office of National Marine Sanctuaries developed the Ocean Etiquette program to promote ocean stewardship and minimize impacts to marine life and habitats.
