The American merchant brigantine Mary Celeste was discovered adrift in which ocean?

Mary Celeste was an American merchant brigantine discovered adrift and deserted in the Atlantic Ocean off the Azores Islands on December 4, 1872. The Canadian brigantine Dei Gratia found her in a dishevelled but seaworthy condition under partial sail and with her lifeboat missing. The last entry in her log was dated ten days earlier. She had left New York City for Genoa on November 7 and was still amply provisioned when found. Her cargo of denatured alcohol was intact, and the captain's and crew's personal belongings were undisturbed. None of those who had been on board were ever heard from again.

Mary Celeste was built in Spencer's Island, Nova Scotia, and launched under British registration as Amazon in 1861. She was transferred to American ownership and registration in 1868, when she acquired her new name. Thereafter she sailed uneventfully until her 1872 voyage. At the salvage hearings in Gibraltar following her recovery, the court's officers considered various possibilities of foul play, including mutiny by Mary Celeste's crew, piracy by the Dei Gratia crew or others, and conspiracy to carry out insurance or salvage fraud. No convincing evidence supported these theories, but unresolved suspicions led to a relatively low salvage award.
