Site 15377 is a shipwreck in the Gulf of Mexico that was likely a three-masted vessel rigged either as a ship, bark, or barkentine. It has copper sheathing on the hull, an assemblage of ceramics, stoneware, and blown glass containers, among other artifacts. In the center of the site is a sheet anchor, stove, and what appears to be the remains of a windlass or possible bilge pump. Judging from the layout of the hull and how boxy it is, it is likely that it was a merchant vessel designed for long ocean voyages. The vessel was probably constructed between 1830 and the middle of the 19th century.

Identified as Site 15377 by the Bureau of Ocean Energy Management (BOEM), this shipwreck site was rediscovered on December 9, 2017, during an expedition led by NOAA Ocean Exploration aboard the NOAA Ship Okeanos Explorer. Remotely operated vehicle (ROV) Deep Discoverer — equipped with an Insight Pacific Zeus Plus camera capable of collecting high-definition footage — was used to document the site, which is at a depth of approximately 700 meters and is 32 meters long and 10 wide.

A photogrammetric model of this site made by BOEM already exists. This model from NOAA Ocean Exploration is based on the same data using footage from timestamps 21:45 to 23:10. The footage was processed into still images using Photoshop and was color corrected. 4,905 images were used for one photo model of the site. After alignment and camera optimization, there were 1,185,218 tie points in total for the model with 98% alignment.
