Photos: Shipwrecks of the Deep Sea

Pirates or Privateers?

Archaeologists are remotely exploring three mysterious shipwrecks in the Gulf of Mexico. The wrecks are likely 200 years old, based on the artifacts littering the deep seafloor. The researchers hope to determine whether the ships sunk together or separately, and whether they were pirates, privateers or government-owned. Privateers were privately-owned ships authorized by government letter to attack other vessels during wartime. Here are some of the amazing photos collected during the exploration.

Heavy arms

On wreck A, one cannon rests on another in this image from a 2013 expedition. The heavily-armed ships lead researchers to suspect at least one of the wrecks were privateers.

New habitat

Debris from shipwrecks provides habitat and food for deep-sea life. Here, a king crab, a white anemone, and stoloniferous corals perch on ship hardware above the surrounding mud.

Tarnish free?

Copper and brass has stayed free of marine growth for nearly 200 years. One of the wrecks had a copper-plated hull.

Staff of life

Wooden ship debris supports a diverse community of sea creatures, until the food supply is exhausted. Here, the tubes of shipworms litter areas once covered with wood.

Anchors away

Lying next to an anchor are the remains of the capstan from the wreck C site in. In the background are fragments of the hull’s copper sheathing.

Unusual find

A rare, unidentified yellow ctenophore, which caused quite a stir among the Okeanos Explorer science team as it drifted into view of the remotely operated vehicle.

A modern mix

The bow section of shipwreck B. Pictured here are glass demijohns, what has been tentatively identified as blocks of tallow and rolls of cattle hides, and a large iron anchor. Modern fishing line is entangled on the shipwreck.

Officers' mess

The stern section of shipwreck B. Pictured here are items that would have been under the control of the vessel's officers: navigational instruments, fine ceramics and liquor bottles.
