While the magnetometer crew conducted its initial search west of Observatory Cay, a second team embarked upon a metal detector survey of the cay itself and searched for evidence of survivor camps associated with the wrecked vessels Bona Vista and Jenny Lind.
The Australian National Maritime Museum and Silentworld Foundation recently led an expedition to the Australian Coral Sea Territory to conduct an archaeological survey of historic shipwrecks lost at Kenn Reefs during the nineteenth century. The Kenn Reefs expedition is a continuation of an ongoing collaborative project between the museum and Silentworld Foundation that commenced in 2009 and led to the discovery that same year of the wreck of the colonial government schooner Mermaid (lost in 1829 on what is now known as Flora Reef). No less than eight vessels are known to have wrecked at Kenn Reefs between 1828 and 1884, and most grounded in relatively close proximity to one another on the largest of the southernmost reefs in the chain, as it was located within an oft-travelled shipping route, but poorly charted until the mid-nineteenth century.
I hope you have been following Alice and Megan’s blogs on the 2009 Mermaid Project over the last six days. Over the last couple of days the dive team have made a number of significant discoveries on Flora Reef. Two days ago during a magnetometer survey on the southern side of the reef the team picked up a small but impressive magnetometer signal about 150 meters offshore from what was then Flora Reef Unidentified shipwreck No 2. A team of divers were sent in and after only a short search located a 5 foot long, wrought iron kedge anchor sitting on top of a coral bommie in 7 meters of water. We know from historical accounts of the wreck that the crew of the Mermaid dropped a small kedge anchor about half a cable length from the stern of the vessel in an attempt to kedge (pull) the Mermaid off the reef. Their attempt failed and the kedge anchor and its coirfibre cable were abandoned.
In itself the discovery of the anchor did not proove that that the wrecksite was HMCS Mermaid and the team continued to survey the site looking for additional information. Yesterday a metal detector survey uncovered a series of anomlies scattered amongst coral rubble on the southern side of the site. These anomlies have now been identified as being casement or cannister shot (packets of ball bearings contained within a small canvas bag of small wooden cannister) the team have also found fragments of copper sheathing, sheathing nails, ship’s fastenings, lead patches and several large magnetic anomalies on the wrecksite. This information along with the position of the wreck and the size of its remains has meant that we are now quite positive that the site is that of HMCS Mermaid wrecked off the Frankland Islands in 1829.
Archaeologists, scientific divers and volunteers divers and snorkellers are continuing their investigation of the site hoping to reveal more information about this fascinating vessel.
