The ocean on the east coast of the United States is the Atlantic Ocean. This ocean borders several states, ranging from Maine in the north down to Florida in the south. The Atlantic Ocean is known for its significant role in trade, transportation, and natural resources. It is also the site of various marine ecosystems, including estuaries and coral reefs. Many major U.S. cities, such as New York, Miami, and Boston, are located along the Atlantic coastline, making it a critical area for economic activities and tourism. Its waters are vital for fishing and recreational activities.
