Bouldnor Cliff – Drowning, desertion and destruction – help save our lost culture

Bouldnor Cliff ExcavationBouldnor Cliff is an underwater Middle Stone Age site that dates to 6,000 BC. This was a time when the hunter gathering epoch was drawing to a close and when Great Britain was being separated from mainland Europe by sea level rise. The lowlands that lay between the two land masses covered around half a million square kilometres and would have been home to many family groups.  They had developed wide-ranging trade links, moving along coastlines and rivers. The land they occupied was rich in vegetation, animals and wildfowl but ultimately it was all to be lost under the sea. These people had to adapt to the loss of land around them as the outline of modern Europe was taking shape. Continue reading

Identifying a Catalina

In February we were contacted by a member of the public who’d recently enjoyed a trip to the Caribbean. Whilst there, he’d been diving off the island of St Lucia and visited the wreck of an aircraft. It was, he said, just inside a reef in shallow water but difficult to access as the waves break over the reef in windy weather.

He only had the one opportunity to visit and even then, could not explore the whole aircraft. With no information available from the team who guided him to the wreck, he was curious as to what it may be and, on his return to England, contacted us to see if we’d be able to help.

His photos illustrate some of the difficulties in maritime archaeology – namely visibility and recording. Not only had the diver been unable to reach the rear of the aircraft, but they hadn’t even been able to see it. Additionally, it is very difficult for someone viewing the photographs later to gauge the scale of the wreck – which is exactly why scale rulers are so important in archaeological recording (not that we would expect a diver on a pleasure dive to take scales with them purely for our benefit!).

The query was sent through to the Trust’s military history expert, Stephen Fisher. At first it looked like a hopeless task as it was barely possible to work out what any part of the front of the aircraft the photographs were looking at, but Stephen was struck by a solitary feature, visible in the bottom left photograph. This strake reminded Stephen of a similar feature he had seen on the nose of the Consolidated PBY Catalina flying boat, a famous aircraft from the period of the Second World War.

Working on this hypothesis, it didn’t take long to match up the other seemingly random features with the Catalina.

With the type of plane now known, it made identifying the actual plane a lot easier. The book BusNos!: Disposition of World War II USN, USMC and USCG Aircraft Listed by Bureau Number by Douglas Campbell lists two possible candidates:

  • Aircraft 2400 Consolidated PBY-5 Catalina (Naval Patrol Squadron 31) based at San Juan, Puerto Rico, reported as having ‘water looped during landing and sank 30-Apr-42 at St Lucia’.
  • Aircraft 7249, Consolidated PBY-5A Catalina (Naval Patrol Squadron 92) ‘force-landed after engine failure and drifted onto reef and sank 14-May-42 St Lucia.’

There were only minor differences between the 5 and 5A and because of the sheer number of individual variations, even between planes of the same model (such as the forward gun position), it wouldn’t be easy to tell one from the other based on the images. The description of Aircraft 7249 sinking on a reef obviously suggests it may be that one.

The diver has passed all of this information to his contacts in St Lucia. Further research and dives to identify this aircraft can now at least focus on two specific aircraft and look for clues as to which it may be.

Across the Seas: French Megaliths in 3D

Hello again,

We have been in France researching La Roche Longue, which is a megalith (menhir) located southeast of Quintin, France. We have worked on developing a 3D model of this stone and its surrounding landscape. The model is derived from UAV (Unmanned Aerial Vehicle), commonly known as drone, images, and constructed using photogrammetry. Using a drone allows us to capture detailed images of these large stones which would otherwise be difficult to get from the ground.

A second 3D model we have been working on is of Allée couverte de Mein-Gouarec à Plaudren. It is a passage grave located near the village of Plaudren in France. Dated around 4,500-4,300 BP, it is a late neolithic piece around 6 meters in length. The tomb features engravings representing the Mother Goddess, including carved out breasts on the back wall. This site was recorded in January this year, using Nikon D200 and D7000 cameras.

 The images are all collected as part of the Common Cultural Connections project. The CCC project is a collaboration between MAT in the UK, Centre National de la Recherche Scientifique in France and University of Cantabria in Spain. The aim of the project is to enhance the understanding of the shared cultural heritage through an innovative mobile exhibition. Read more about the project here

Welcome

 

Hi everyone,

We are the Maritime Archaeology Trust, a charitable trust that researches maritime archaeology and heritage. We are forward thinking professionals and researchers who seek to utilise traditional archaeological techniques with new innovative ideas, techniques and technologies. To do this, we combine historical and archaeological studies, with state-of-the-art geoarchaeology, digital technology and 3D modelling.
