Past Projects
Ben Franklins Pirate Fleet
Deep-sea investigation off the coast of Wales, seeking a Revolutionary War-era American privateer shipwreck linked to Benjamin Franklin's commissioned fleet.
Underwater archaeological expedition off the coast of Wales, led by Jay Usher's DeepTrek team, seeking a shipwreck linked to a little-known aspect of the American Revolutionary War. The source explains that to secure the exchange of American prisoners suffering in British jails, Benjamin Franklin commissioned a fleet of privateers—privately owned, armed ships operating under American authority—to capture British sailors. These privateers, like the Black Prince captained by the Irish fugitive Luke Ryan, engaged in commerce raiding, looting merchant vessels and taking hostages, sometimes against Franklin's goal of simply capturing prisoners. The diving team uses advanced technology like sonar and sub-bottom profiling to excavate a treacherous wreck site, recovering artefacts like a keel shoe and French-origin cannonballs consistent with the privateer period and outfitting. Archival evidence confirms Franklin's ships operated near the site, leading the team to believe the wreck is either a member of Franklin's 'Black Fleet' or an escort ship mentioned in local legends, revealing a gritty, piratical chapter of American history.

The Search for Sir Francis Drake
Deeptrek, an international consortium of expert divers and maritime archaeologists, headed an expedition off the coast of Portobelo, Panama, to locate the final resting place of Sir Francis Drake.
The primary objective of this ambitious undertaking was to locate the final resting place of the legendary 16th-century English admiral, Sir Francis Drake. Drake, who died of dysentery in 1596 during his final campaign in the New World, was famously buried at sea in a lead coffin. The expedition, led by Deeptrek's Jay Usher and supported by explorer and entrepreneur Pat Croce, brought together a world-class team to search for this invaluable piece of maritime history.
During the 2011 investigation, the Deeptrek team, utilizing advanced underwater technology and meticulous archaeological methods, made a monumental discovery. While the admiral's coffin remained elusive, the divers successfully located the wreckage of two 16th-century vessels submerged in the bay. These wrecks are strongly believed to be Drake's final two ships, the Elizabeth and the Delight. Historical accounts confirm these ships were deliberately scuttled by Drake's own crew shortly after his death, preventing them and their armaments from falling into Spanish hands.
The discovery of the Elizabeth and the Delight represents a major archaeological breakthrough, providing tangible links to the final days of one of history's most renowned and controversial seafarers. This find, a direct result of Deeptrek's expertise and perseverance, marks a critical milestone in the ongoing quest to solve the mystery of Drake's Panamanian legacy. It has provided invaluable new insights into the 16th-century conflict in the Caribbean and cemented the team's reputation for tackling the world's most challenging underwater historical investigations.
This complex operation showcased Deeptrek's capability to manage demanding deep-water archaeological projects in challenging environments. The team navigated difficult conditions to successfully identify, survey, and document the submerged structures, applying a sensitive, non-intrusive approach to preserve the integrity of the invaluable 400-year-old site. The data collected by our specialists has been crucial in the efforts to officially verify the ships' identities and offers a rare, tangible window into the Elizabethan era of exploration and naval warfare. Deeptrek remains dedicated to applying cutting-edge technology and unparalleled expertise to respectfully uncover and protect the hidden stories of our shared maritime past.
The Wreck of the HMS Fantome and its Associated Plunder Ships
An archaeological investigation and recovery of the HMS Fantome, a British warship lost off Nova Scotia in 1814 while escorting vessels carrying plunder from the burning of Washington D.C.
The HMS Fantome was a 300-ton British brig-sloop that participated in the War of 1812, including the infamous burning of Washington. In late 1814, while escorting a convoy of captured American "plunder ships" from the Chesapeake back to Halifax, the Fantome and several of its convoy were lost in a storm off Prospect Bay, Nova Scotia. The transport vessels were known to be carrying significant goods and valuables looted from Washington, Alexandria, and Castine, making the wreck site one of high historical and material importance. Initial historical research conducted by Deeptrek identified the names of the transport ships and confirmed the nature of their cargo.
Deeptrek was contracted to conduct a full archaeological assessment and recovery operation on the site. Initial survey operations utilized a Geometrics 882 magnetometer to identify areas of interest in the challenging, high-energy surf zone where the vessel was lost. Diver reconnaissance subsequently located a large, discontinuous concretion field representing the primary artifact scatter from the wreck. A stainless steel datum line was established across the seabed, allowing for systematic mapping, excavation, and recovery of the shipwreck material. Due to the site's exposure to harsh oceanic forces, artifacts were heavily concreted and buried under an overburden of rocks and boulders, necessitating the use of hammers, chisels, pry bars, and lift bags for extraction.
Findings and Recoveries:
The recoveries confirmed the identity of the vessel and its involvement in the War of 1812. Numerous artifacts bearing the British "broad arrow" mark of crown ownership were found, including copper sheathing, nails, bolts, and pins. Recovered cannon shot, ranging from 1lb grape shot to large 28lb carronade balls, corresponded with the Fantome's known armament. Military buttons from both British Naval forces and the 2nd American Artillery were also discovered, directly linking the wreck to the conflict. Other significant finds included Spanish-American silver coins (8-real pieces), an English one-penny pay token, fragments of an octant, and various glassware and pottery shards typical of the early 19th century. The findings provided invaluable insight into the vessel's history, its final voyage, and the nature of the plunder it was escorting.
A project to survey and recover one of the most complete 19th-century composite barque shipwrecks in Australia, lost off the coast of South Australia in 1867.
The Zanoni was a 338-ton composite barque built in Liverpool in 1865 for the East India trade. In February 1867, laden with bark and over 4,000 bags of wheat, the vessel left Port Adelaide for London. While crossing the Spencer Gulf in initially fine weather, the Zanoni was struck by a sudden and violent squall. The ship capsized and sank within five minutes, though fortunately, all sixteen souls on board were rescued. The wreck's location remained a mystery for over a century.
The shipwreck site was rediscovered in 1983 by abalone divers in 18 metres of water. Deeptrek personnel were subsequently involved in the project to survey and recover the site for the Department of the Environment and Planning of South Australia. The investigation found the Zanoni to be one of the most complete and well-preserved examples of a vessel of its type and age in Australia. Lying on a barren seabed, the intact hull has since become a vibrant artificial reef, completely covered by sponges and inhabited by numerous species of fish, making it a site of significant archaeological and ecological value. A collection of its artifacts is now on display at the Maritime Museum of South Australia.
