Burial at sea describes the procedure of disposing of human remains in the ocean.
Two reasons for burial at sea are if the deceased died while at sea and it is impractical to return the remains to shore, or if the deceased died on land but a burial at sea is requested for private or cultural reasons.
Burial at sea services are available at many different locations and with many different customs, either by ship or by aircraft. Usually, either the captain (or commanding officer) of the ship or aircraft or a representative of the religion performs the ceremony. Legally, a captain can bury remains at sea, provided that environmental regulations are satisfied. In the United States, ashes have to be scattered at least 3 miles from shore, and bodies can be given to the sea if the location is at least 600 feet (200 m) deep.
