200 Year Old Shipwreck Discovered In Northern Gulf Of Mexico

During a recent northern Gulf of Mexico expedition, NOAA, the Bureau of Ocean Energy Management (BOEM), and partners discovered an historic wooden-hulled vessel which is believed to have sunk as long as 200 years ago. Scientists on board the NOAA Ship Okeanos Explorer used underwater robots with lights and high definition cameras to view remnants of the ship laden with anchors, navigational instruments, glass bottles, ceramic plates, cannons, and boxes of muskets.

The NOAA-funded 56-day expedition that ended April 29 was exploring poorly known regions of the Gulf, mapping and imaging unknown or little-known features and habitats, developing and testing a method to measure the rate that gas rises from naturally-occurring seeps on the seafloor, and investigating potential shipwreck sites.

The shipwreck site was originally identified as an unknown sonar contact during a 2011 oil and gas survey for Shell Oil Company. The Department of Interior’s Bureau of Ocean Energy Management (BOEM) requested this and other potential shipwreck sites be investigated during NOAA’s Gulf of Mexico expedition. Surveys and archaeological assessments are required by BOEM to aid in its decision-making prior to issuing permits for bottom-disturbing activities related to oil and gas exploration and development.

“Artifacts in and around the wreck and the hull’s copper sheathing may date the vessel to the early to mid-19th century,” said Jack Irion, Ph.D., a maritime archaeologist with BOEM. “Some of the more datable objects include what appears to be a type of ceramic plate that was popular between 1800 and 1830, and a wide variety of glass bottles. A rare ship’s stove on the site is one of only a handful of surviving examples in the world and the second one found on a shipwreck in the Gulf of Mexico.”

Significant historical events occurring in the regions around the Gulf of Mexico during this time include the War of 1812, events leading to the Texas Revolution, and the Mexican-American War, he said.

“Shipwrecks help to fill in some of the unwritten pages of history,” said Frank Cantelas, a maritime archaeologist with NOAA’s Office of Ocean Exploration and Research. “We explored four shipwrecks during this expedition and I believe this wreck was by far the most interesting and historic. The site is nearly 200 miles off the Gulf coast in over 4,000 feet of water in a relatively unexplored area.”

The expedition also discovered areas exhibiting rich biodiversity. At the base of the West Florida Escarpment, a steep undersea cliff, explorers found a “forest” of deep corals, several of which were new to scientists on the ship and ashore. For several days the expedition team also imaged deep-coral communities in the vicinity of the Macondo oil spill site. On another part of the expedition, team members designed and installed a device on the ship’s undersea robot system, or ROV (remotely-operated vehicle), to measure the rate that gas rises in the water column.

The copper has turned green.

Artifacts include ceramic plates, platters, and bowls; and glass liquor, wine, medicine, and food storage bottles of many shapes and colors (some with the contents still sealed inside).
