Lost beneath the waves: Ancient Landscapes and Wartime Wrecks

On Sunday 16th October, Garry Momber, Director of the Maritime Archaeology Trust, will be speaking at the Isle of Wight Literary Festival.

Garry’s talk will cover two archaeological projects of major interest and importance to the Island:

Bouldnor Cliff: A submerged pre-historic site eleven meters below the surface and approximately 250 metres offshore of Bouldnor, near Yarmouth. Excavations have been continuing at Bouldnor Cliff since the 8,000 year old Mesolithic settlement was first identified in 1999, when a lobster was seen throwing Stone Age worked flints from its burrow. Since then the site has yielded numerous secrets. The material so far recovered has already demonstrated that the technology of the era was 2,000 years ahead of what archaeologists previously believed.

HLF Forgotten Wrecks of the First World War: With over 1000 wartime wrecks along England’s south coast alone, the conflict of WW1 has left a rich legacy and many associated stories of bravery and sacrifice. These underwater memorials represent the vestiges of a vital, yet little known, struggle that took place on a daily basis, just off our shores.

Time: 10.30 – 11.30 am

Forgotten Wrecks of the Devon Coast: Geophysics and Diving

As part of the Forgotten Wrecks project this summer the Maritime Archaeology Trust sent out a team of divers to find and document a number of WW1 wrecks off the South Devon Coast. In order to assist the divers in finding these wrecks bathymetric maps were consulted. Much like navigational charts used by mariners these maps show the topographic features of the seafloor. However, modern techniques such as multibeam bathymetry, paint a far higher resolution image of the seafloor with measurements made every few metres.  As a result, even fine details such as the orientation of shipwrecks and the positions of larger objects such as boilers and anchors on these sites, can be seen.

Within the area surveyed by the Maritime Coastguard Agency between 2012 and 2015 (data freely available from aws2.caris.com) 31 of the 48 wrecks which had been identified as lying within the south Devon study area reviewed ahead of diving operations were visible.

Once identified a zoomed in map was created of each wreck. The examples shown here are of the British Navy trawler, the Benton Castle and cargo ship, the Newholm. Both of which sank after hitting mines, leading to the loss of 30 lives in total. These images and images of the other wrecks were used by the diving team to help select individual sites to dive and then plan their dives more effectively.

The dive team operated out of Dartmouth using Falcon Diving Charters (http://falcondivingcharters.com/) during the week of 27th June to the 1st July. Despite some challenging weather conditions the team managed to reach a number of the Forgotten Wrecks to undertake survey and photogrammetric recording.

Bouldnor Cliff Day Two: 15/06/2016

Photo 15-06-2016, 15 03 58  Another day on Bouldnor Cliff reveals another exciting discovery. Garry Momber took part in the day’s first dive, and began to clear away some of the layer of mud covering the site. Underneath this mud he found a series of planks lying parallel to each other. Further dives will include more work on this potential platform, so the archaeologists can try to interpret the feature and its purpose. Yesterday, a diver found and recovered a small piece of flat, pointed timber that may turn out to be the end of a plank. Garry also recovered a small piece of wood, demonstrating the excellent preservation on this site. It is still possible to find organic material that is over 8,000 years old!

Photo 15-06-2016, 15 20 56Miguel, Ziad, and Mohamed are still hard at work on the photogrammetric work. Miguel has been acting as underwater photographer, taking pictures of Garry at work and using a 6m x 2m grid to take photos to create a photogrammetric model of the site and some of the exposed timbers. Ziad and Mohamed are doing similar work, both with and without photogrammetric targets. The divers are working hard to ensure they don’t damage any of the exposed timbers as they do their work, and are being careful where they use targets. In places where the timber is fragile, it may be better to work without them. Eventually, the hundreds of photos taken will be combined together. They will be used to create a 3D model of the Mesolithic site, which can be manipulated and interpreted, and used for further study.

To everyone’s delight, the weather is much improved from yesterday, and conditions are much calmer. This is Ziad and Mohamed’s first time diving in the UK, but they are coping with the temperatures very well! On the third dive, the divers brought up some more timber which will be cleaned, and then studied for interpretation.

Every dive is revealing something new about the site. The researchers are keen to see what else can be learnt from this ancient settlement. Bouldnor Cliff is a unique site, and it has plenty more secrets to discover!

 

Bouldnor Cliff Day One: 14/06/16

The MAT Bouldnor Cliff dive team 2016

Just off the Isle of Wight is the site of Bouldnor Cliff. Bouldnor Cliff was a Mesolithic settlement, dating to 8,000 years ago. The finds from this site include worked timber and flints, and show that the inhabitants were using technology that was 2,000 years more advanced than expected in a site of this age!

The Mesolithic site is about eleven metres below the surface, and is part of the Solent Maritime Special Area of Conservation. Sadly, the tides of the Solent are eroding the site. More material is constantly being exposed, and subsequently is being threatened. The Maritime Archaeology Trust is working hard to monitor the site’s condition, and to recover material that is coming under threat.

The MAT is carrying out dives to create a record of the site, to document any changes that are taking place, and any exposed material. It is important to make frequent records of the site, and the plan is to use photogrammetry to create a 3D model. Divers first make a ‘pre-disturbance survey’, in order to ensure that the site is properly catalogued before making and changes or disturbing anything. Once the researchers are confident that there is a good record of the site and its contents, they are able to examine and rescue artefacts, and bring them to the surface for further study. These can be compared with the plan, in order to make note of where the artefacts were find, and piece together the site: a bit like putting together a big puzzle.

The divers set up a baseline at the site, in order to carry out the recording. A photographic survey was undertaken, to record the newly exposed features and document the site in its current condition, before any further work.

The first thing seen by the divers as they approached the site was some newly exposed timber, protruding from the bank. This timber was not visible last year, and has been revealed by the erosion. It appeared to have been worked, and looks like it may even be the remains of a platform. Later dives will aim to further study these timbers, and rescue them.

A later dive revealed a fellow archaeologist digging at Bouldnor Cliff: a lobster, with a collection of worked flints outside his burrow. Lobsters are frequent visitors to the site, and often turn up flints such as these. With the lobster’s help, the next dive recovered five small worked flints, and they were brought to the surface and inspected for the first time in 8,000 years.

The first day was a grand success, with four dives in total. The last of these dives included two new visitors; volunteers from Egypt who had come to see the site and assist in the photogrammetry. They were very impressed with what they saw, and can’t wait to return to the site and continue their study. The work at Bouldnor Cliff will continue, to ensure that the site is safe, any threatened material is recovered, and that we learn everything we can from this exciting site.

Bouldnor Cliff #3 – Sunken Secrets

This is the last video before we go out diving!

This time Garry is visiting the Sunken Secrets Museum on the Isle of Wight. He shows us various pieces of timber, flint and string that has taught us a lot about the people living here during the mesolithic era. The findings are proving to be highly important, because they show the people were way more advanced than previously thought, by as much as 2000 years.

Why is Bouldnor Cliff so special?

In 1999, whilst out diving, MAT discovered what we know as Bouldnor Cliff by the Isle of Wight. This used to be a highly populated area of land. Ever since the discovery there have been ongoing excavations and investigations to uncover the complex life of the people living on this piece of land during the mesolithic era, about 8000 years ago.
