Ice begins to melt when its surroundings rise above its freezing point, that being 32 degrees Fahrenheit (0 degrees Celsius). Depending on the salt content and the presence of other substances, that freezing point may be an even lower temperature.
Another highly probable cause of death was injury. Because some of the bodies retrieved from the water by the recovery ships had been too badly damaged to preserve through embalming and consequently had to be buried at sea, itâs very likely that some passengers died as a result of catastrophic injuries.
Was John F. Kennedy buried at sea? No, he was buried at the Arlington national cemetery in 1963. On a related note: JFK was transported from Dallas (after his death) to the capitol in a casket purchased from â¦Elgin Casket Company in Dallas.
