#MuseumWeek2017: Theme of the day, TRAVEL!

Museum Week is an international online event that is running from 19th to 25th June 2017. Organised in collaboration with UNESCO, the Museum Week is a chance for heritage institutions across the world to share and talk about our passion for heritage with the public through social media. This year we are celebrating equality by dedicating the Museum Week to all women in the world.

The Maritime Archaeology Trust will be sharing with you our take on Museum Week. In collaboration with the Shipwreck Centre and Maritime Museum on the Isle of Wight we will be looking through their collections and bring you artefacts and histories that are linked in with the theme of the day.

Saturday’s theme for the week is TRAVEL!

Artefacts recovered from shipwrecks have a natural connection with travel. Either they have been on board the ship and travelled to the same destinations or they originate from the destinations visited by the ship. The Shipwreck Centre’s collection has numerous items that have a connection to maritime travel. Some are extremely fascinating to the viewer, such as the “Feejee mermaid” that was discussed in a previous blog post.

On the wreck of the SS Camberwell, divers found Indian rupee banknotes which were still recognisable. Remarkably these had survived for 70 years before they were brought back to the surface. The SS Camberwell sunk on the 18th May 1917 when it struck a mine and sunk 6 miles SE of Dunnose Head on the Isle of Wight. Sadly seven people perished with the sinking of the ship, all with Indian heritage.

India was officially recognised as a British colony in 1858 when the Crown took control of India from the East Indian Trading Company. Lascars, or Indian sailors had already been employed by the EITC as sailors in the 17th century. With the Royal Navy’s demand for sailors during wars the number of Indian sailors quickly rose. By 1917 the number of Indian sailors on British registered vessels were up to over 51 000.

The rupees found on the SS Camberwell tell the journey of the people connected with the ship. Like the mermaid and the HMS Victory’s logbook mentioned earlier this week, the bank notes have travelled far before ending up on display at the Shipwreck Centre on the Isle of Wight. Just like the people on board the SS Camberwell before it sank in 1917.

The Friday theme during Museum Week is BOOKS!

Or in our case, more accurately logbooks! A logbook or ship’s log is a record of important events that happened during the ship’s journey. This also includes management, operation and navigation of the ship.

The logbook was a key part of navigating a ship. Navigation is largely based on defining the latitude and longitude of the ship’s location. The longitude is the more difficult one to determine, as it requires the sailor to know the local time to determine what time zone they were travelling through, and as such determine their location by combining the ship’s latitude position. Medieval sailors were unable to determine the latitude-longitude completely accurately, due to the technology that was available to them at the time. As such the sailors heavily relied on the dead reckoning system. The dead reckoning principle works the following way. The sailor would start by taking a known or assumed position of the ship. Then the heading and the speed of the ship from this location would be measured, as well as the speed of the ocean currents, the leeward (downwind) drift, and how long the ship spent at each heading. Based on this information, the navigator could determine the course of the ship and how far the ship had travelled. This was noted down in the logbook, which was then used to as a reference to check the accuracy of the predicted dead reckoning.

A ship’s logbook holds a huge wealth of material for maritime archaeologists. Finding a ship’s logbook is like finding a gold mine. We can retrace the journey of the ship from the logbook and compare that to any remains we may have found. This is valuable when trying to determine the identity of a wreck for example. It also gives us a great insight into what life on board was like. For a great example is an extract from the logbook of the Halsewell.  The Halsewell was a merchant ship based in the East India Company. There is a record in their logbook from 19th October 1781, where Lord Nelson (then Captain) recruits experienced sailors for the Navy, leaving the ship with only “foreigners and servants”.

The Shipwreck Centre also holds logbooks in their collection. An example can be seen here of the logbook from the HMS Victory which subsequently became the logbook of the HMS Duke of Wellington, the ship that replaced the HMS Victory as the Port Admiral flagship at Portsmouth between 1869 and 1891 (McKay 1987:9). Next time you visit the Shipwreck Centre and Maritime Museum on the Isle of Wight, try to spot the logbook which is on display next to old toothpaste and wood from the Mary Rose!

The Thursday theme is, STORIES!

We have a special one for you today! There are probably very few people in the world who haven’t heard about the myth of mermaids. But did you know that in the Victorian period “real” mermaids were sold as collectables?

The myths of the mermaids and mermen date back as far as 1000 BC. The Assyrian legends told of a queen who accidentally killed her lover. In despair she threw herself into the sea to transform into a fish but the water only transformed half of her body and as such she became half fish and half human.

Stories of similar creatures can be found across the world. In Africa the legend of Mami Wata, a powerful water spirit, sometimes takes the shape of a mermaid. She is not too dissimilar from the legends of European mermaids (think HC Andersen’s “The Little Mermaid”). Interestingly the legend of the mermaid Lasirn in the Caribbean has resemblance to both the African and European legends. We also find records of mermaid stories and sightings from the American, Inuit, Indonesian, Australian and Japanese cultures.

The collectable mermaid hoax has been around for centuries. However, the most famous version was created by an American conman, P.T. Barnum, in 1842. Known as the “Feejee mermaid”, it was said that this mermaid corpse had been caught near the Fiji islands in the South Pacific. In actual fact the head of the “mermaid” was of a monkey while the tail was from a fish. Put together and dried out it does make for a quite convincing deep-water creature. During the Victorian period people would buy these “mermaids” as collectables from their trips. Especially in Japan this became a very popular thing to sell to the tourists. The “Feejee mermaid” is now often referred to as the Japanese monkey-fish.

When you visit the Shipwreck Centre and Maritime Museum on the Isle of Wight be sure to check out the “Feejee mermaid” we have in our collection!

Did you know that at the Shipwreck Centre we hold a collection of antique diving gear? Augustus Siebe, who is a German born inventor, is credited as the first person to design the closed diving suit, i.e. full suit and helmet in one. The design came about after he was contacted by the Deane brothers who wanted Siebe to come up with a new helmet design to replace their own. The Deane brothers are well-known in maritime history. They were the first people to discover the wreck of the Mary Rose among other things.

The first design of the Siebe diving suit came about in 1839. Still a century after its creation – Siebe’s diving suit was still used all over the world. Martin Woodward, the founder of the Shipwreck Centre and Maritime Museum on the Isle of Wight, proved that the antique diving suit design can still be used when he tried it out in the 70s.

Diving Week 13th to 16th June 2017

The Maritime Archaeology Trust’s first proper fieldwork diving week took place in June. We were joined by researchers from the ForSEADiscovery  project who specialise in analysing wood for maritime archaeological research.

Setting off from Lymington in the New Forest aboard the Wight Spirit we headed off towards the Isle of Wight. The weather was delightfully sunny and we were hoping for great visibility below the surface!

The first of our chosen sites was the SS South Western. She was sunk by a torpedo south of the Isle of Wight on 16th March 1917, with only 6 survivors out of a crew of 32. Many of the crew members had links to Southampton and consequently the SS South Western becomes a prominent part of the local history. The ship is part of our current Forgotten Wrecks of WWI project which is looking at ships that were lost during WWI, of 1914 to 1918, on the south coast of England. More on the project can be found here .

The aims and objectives for this site was to identify some key features on the ship. This included a detail recording of the cargo and boilers, and also locating the ship’s gun. The dive team managed to achieve a good amount of data for photogrammetry . This data will be compiled into a detailed 3D model for us to study in the comfort our dry (but very hot!) office. For an example of what a photogrammetry model looks like, please see the model of the HMD John Mitchell here.

The second wrecksite we wanted to look at this week was the SS Hazelwoood. The ship hit a mine on the 19th October 1917, with the loss of all 32 crew members.  The location of the Hazelwood is still to be positively identified. However, our dive boat skipper and historian, Dave Wendes, believes that the wreck identified as the Saxmundham is in fact the SS Hazelwood. The wreck site is located at a depth of 32 meters. Previous dives on the site done in 2015 were plagued by poor visibility and as such we weren’t previously able to determine the identity of the wreck. This time the conditions were slightly better and we were able to conduct a photogrammetry survey. The photos taken of the site will be compiled into a 3D model which will hopefully help us determine the identity of the wreck once and for all.

The final site we looked at during this week was the submerged Mesolithic landscape at Bouldnor Cliff. The site dates back about 8000 years and has in-situ archaeological remains which are connected with the submerged landscape. The Mesolithic peat deposits lie at a depth of 12 meters, while two additional peat layers above broadly date to the Neolithic and Bronze Age. The aims and objectives of this survey was to check the erosion rate against the previously placed datum points across the site. We also took several sediment samples for palaeo-environmental analysis. Previous samples have concluded that e.g. wheat arrived in Britain 2000 years before we have evidence of humans farming it. Hopefully these new samples will add further knowledge into the nature of the landscape during the Mesolithic.

During the diving week we also had the pleasure of the company from a reporter, Rikke, who is doing coverage for BBC 3. Stay tuned for more updates during the summer!

Qatar Marine Archaeological Project (QatarMAP)

The Qatar archaeological research and exploration project built on the work undertaken by the Qatar Museums to locate and record the submerged cultural heritage. The aim of underwater fieldwork was to begin condition surveys of known submerged marine archaeological heritage sites. The results will enhance the maritime Historic Environment Record with the additional benefit of making the underwater heritage resource more accessible to the Qatari population.

In the long term, areas of the sea bed will be surveyed to locate and identify more of Qatar’s underwater cultural heritage which includes submerged landscapes as well as shipwrecks. The Maritime Archaeology Trust (MAT) is working with the University of York, the Qatar Museums and Qatar University on the Qatar Maritime Archaeology Project (QatarMAP) to carry out these marine archaeological investigations. MAT divers visited Qatar in early May and diving from the dive boat Janan, with the help of divers from the Qatar University, carried out photographic survey over some shipwreck sites to produce 3D photomosaics which were calibrated with measuring scales positioned at different locations.

The MAT dive team are now back in Qatar to continue the work. Along with continued processing of data collected during the first week’s visit, testing and checking of geophysical equipment has been taking place until the bad weather abates which is likely to be this evening.

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

Location: Northwood House, Isle of Wight

Forgotten Wrecks of the Devon Coast: Geophysics and Diving

WholeAreaMap

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: A World Class Site

Mohamed Ziad

Mohamed and Ziad

Bouldnor Cliff isn’t just important from a British perspective: it is a unique site that interests people from all over the world! The diving team included archaeologists from the Maritime Archaeology Trust and even two divers who’d traveled all the way from Egypt to help with the work and see the remains of the Mesolithic settlement. Ziad and Mohamed flew to Britain when volunteers were needed to join the Bouldnor Cliff survey, and came to help with the photogrammetry work around the site. They’ve done work all around the world, including in Montenegro, Lebanon, Egypt and Italy, but this was their first time diving in the U.K.

Ready for that renowned British summer, Ziad and Mohamed joined the team on the boat, keen to explore the famous site. Undeterred by the wind and rain of the first day (it is summer, after all), they were ready to get stuck in and brave the chilly Solent. Layered up and as prepared as can be for the colder climate they jumped in to get to work. The cold was no match for their enthusiasm and they worked hard, familiarising themselves with the site and the new conditions.

And what did they have to say after their first dive? Ziad had only one word: ‘challenge’!

Now used to the cold and the weather, they carried on diving on the site, contributing hundreds of photos to the photogrammetric survey, and taking footage on a GoPro. Their dedication is such that the skipper even poured warm water into their wetsuits before a dive! Inspired by Ziad’s one-word summary, Mohamed described the site as an ‘adventure’.

Ziad and Mohamed aren’t the only members of the #SaveBouldnor team from abroad – Sarah is from the United States, and Miguel is a PhD student from Lisbon, Portugal. Sarah works at the Maritime Archaeology Trust, and considers the site to be ‘groundbreaking’!

Miguel came to Bouldnor Cliff to gain experience in a new environment, and to improve his skills in 3D reconstruction and recording. Miguel described the site as ‘exciting’ and has contributed a lot of work to the photographic record.

It’s not just maritime archaeologists who find Bouldnor Cliff fascinating – Andy has worked closely with the Trust for fifteen years. He finds the site ‘remarkable’, and, as a long-time diving enthusiast, is helping out on-site.

Bouldnor Cliff is a special site that is always turning up new information and fascinating artefacts. It has something of interest for people from all over the world, from different backgrounds, and this multi-national team has come together to work to save Bouldnor, and learn its secrets. Work like this is invaluable, and will contribute to the continuing record of Bouldnor Cliff, as the MAT monitor the site’s condition and explore new features.

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!
