Three Oceans Bordering the United States

The United States has coastline on three oceans:

1. Atlantic Ocean - Eastern seaboard (Maine to Florida) including Gulf of Mexico
2. Pacific Ocean - Western coastline (Washington to California) including Alaska's southern coast
3. Arctic Ocean - Northern Alaska coastline (Beaufort and Chukchi Seas)

This three-ocean coastline is shared only with Canada (Atlantic, Pacific, Arctic) and Russia (Arctic, Pacific, Atlantic via Baltic/Black Seas). It gives the U.S. unique strategic, economic, and environmental connections across the globe.

The Atlantic and Pacific coasts have historically driven commerce, immigration, and naval strategy. The Arctic coast is gaining importance with climate change opening navigation routes and resource access.
