This octant was discovered during a Windows to the Deep 2018 expedition dive on the Blake Ridge Wreck. The wreck was originally discovered by a team from Duke University in 2015 and is likely an early 19th century wreck. Indicative artifacts imaged during the dive included an octant, bottles of wine, ceramic jugs, containers for food and other liquids, a small sewing kit with a pile of brass buttons, a slate, a vase, a tobacco pipe, and a comb. Data collected during the dive was used by the Bureau of Ocean Energy Management to develop a 3D photogrammetry model of the wreck (model available here: sketchfab.com/models/eea2f59719934994bc238bf4689b1e32).
