Studying maritime archaeology in Esbjerg: Field school and summer events

We have been very busy the last few months with school, traveling and celebrating the holidays. That is why we will take you a few months back and tell you about all the exiting things we have been doing since May.

The International Viking Market

A few weeks before our final exam of the year, the International Viking Market was held in the Viking Centre in Ribe. To gain extra information about the Vikings for our exam, but also for a nice day out, we had organized a trip to the Viking Centre with MASE. In the Viking Centre people dress up and live like the Vikings did, and it can be compared to the Dutch theme park Archeon. Houses, food, games, everything was made and done as it would have been in the Viking Age hundreds of years ago. We went into different houses and even had the change to feel like Ragnar Lothbrock, by sitting in the Viking throne. We played Viking games (board and throwing games, no beer involved J) and witnessed a Viking battle and a horse show. On the market itself, they sold everything that would have been used during the Viking Age. The people who sold their goods came from all over Europe. It was a very interesting and nice day, and we learnt a little bit more about the Vikings.

Field school

The field school started on the first of June., and took place in Mukran on the island of Rügen, Germany. We stayed on the campsite of a hostel in Prora. This area is famous for the colossal hotels that were built for Nazi-tourism. The hostel itself had been renovated from Nazi-hotel-ruin to the Jugendherberg where we stayed. For three weeks we dived at a 16th century wreck, probably of Danish origin. We made drawings, photos and videos of the wreck, and also got coordinates so we have the exact location of the wreck. The wreck had first been documented in the mid ’80’s and since then a lot of archaeologists and divers have had a look at it. The documentation of the wreck was however not up to today’s standard, and that is why it was up to us to make a final and exact recording of the wreck. During previous investigations quite a lot of finds were recovered. Therefore, we also had a look at these finds. The finds of the wreck were mostly located in Schwerin, a two-hour drive from Prora. Here we documented all the finds. There were guns, one wrought iron gun and a bronze gun, a lot of wooden artefacts, pottery and metal objects. These finds were photographed and the interesting ones were also drawn. For the two guns a photogrammetry model was made, so we can have a good look at them in 3D.

Every day there was a dive team and a land team. The dive team was split up in two teams, one would dive in the morning, the second group would dive in the afternoon. The wreck needed to be cleaned first, which took much longer than expected, since the wreck was totally covered with seaweed and rocks. All the timbers needed to be tagged and drawn separately. Once the wreck was cleaned and the timbers were tagged, a diver with a GoPro could film the wreck in order to make a photogrammetry model of it. This coming semester we will work on the model and other documentation, and write a report on the wreck. The land team was responsible for the finds. These finds were given a number, were drawn and photographed. They also worked with a Total Station, to shoot the positions of the shipwreck.

Besides all the work we had to do during the field school, we also had a few days off, when the weather was ‘bad’. Since the site was located on the Baltic Sea coast, an easterly wind caused high waves, which was too dangerous to dive in as the site was really close to shore and only 3 meters deep. But although we couldn’t dive it was really beautiful, sunny weather. We spent those days off in the beautiful nature park on Rügen, in the Hanseatic city of Stralsund, and walking and cycling on the island. It was an amazing place to be, with a lot of history and beautiful nature.

Sailing in Roskilde

Only one day after we came back from the field school, we had another trip planned. This time we went back to Roskilde. The first time we went there, we spent our day looking at how Viking boats were built and how the Vikings lived. This time we got the experience at how to sail like a Viking! We sailed on a replica of a clinker-built boat, that was built originally in Norway. First we needed to row out of the harbour, before we could start sailing in the Roskilde Fjord. During the 2 hour sailing trip we learnt all about rigging, sailing and steering. We did a lot of different sailing-techniques, which made it really exiting.

Introduction first-years

After a two-month holiday, we and other members of MASE organized an introduction for the new first year students. We went to Ribe, the oldest town of Denmark, where we got a tour from the Viking Museum through the town. It was really interesting, and even though we had the tour last year as well, we still learned some new things about the town. After the tour we had some free time, so we showed some of the people some nice places in the town. Afterwards we headed back to Esbjerg, where we had a nice barbeque to finish the day.

Classes have started again. In the next blog we will give an overview of these classes and what can be expected from them. Until next time!

Goddag!

Studying maritime archaeology in Esbjerg: the second semester

Time flies, and the second semester of the Maritime Programme in Esbjerg is almost over! This second semester consisted of four courses:

  • Maritime Material Culture
  • IT & Remote Sensing
  • Preparation for the field school
  • Special Topics

Maritime Material Culture
During this course, we got introduced to different maritime material cultures from the Stone Age to the present day. We learned all about material such as pottery, cannons, anchors and many other objects. To learn more about ceramics from the Mediterranean our class went to Odense, where they have a big collection of Mediterranean artefacts. Also an important part of this course was ship construction from different centuries and areas. We went to the Roskilde Viking museum to learn more about Viking ship construction, and about experimental archaeology. We got a very interesting presentation on the famous ship burial Oseberg, which was found in Norway and dates to around 820 AD. After that we got a tour through the boat building wharf, and had a chance to look at the five Skuldelev ships inside the museum. In June we are going to sail on one of the reconstructed Viking ships!

We got an explanation on experimental archaeology during the tour of the boat building wharf.

IT & Remote Sensing
This course is a continuation of the methods course in the first semester, and is more practical. During this course we learned how to work with the software QGIS and with Inkscape. We learned how to make logos and how to digitalize field drawings in Inkscape, and how to analyse data and make maps with QGIS. Part of the course was a visit to Schleswig, where we could see how a sub-bottom profiler works, and how to do a survey with such a device. With a sub-bottom profiler, it is possible to detect archaeological sites and wrecks partially or wholly embedded in the sea-floor sediments. Unfortunately, nothing was found during this expedition. While we were in Schleswig, we got time to check out the early 4th century Nydam boat, which is on display in the Gottorp castle. It was much more impressive in real-life than you would expect. The boat is well over 23 m long and there was place for 30 rowers. This boat is one of the earliest examples of clinker (overlapping planks) construction.

Field school
The field school this year takes place in June in northern Germany. We are going to record a 16th century carvel-built ship. To prepare for this field school we made a plan which details how we are going to clean, dive and record the shipwreck. Next school year, after the field school is done, we have to make a report of the recording.

Special Topics
Special Topics is a course, which is focused on the field school. In order to better ‘understand’ the 16th century shipwreck, we have researched shipbuilding construction from around the same time period. The class has been divided into different groups for this, and each group is looking into shipwrecks from a specific region. The different groups are: British Isles, Baltic Sea, Dutch, Mediterranean and French. Guess what we did.. A database has been created in which the different construction elements of each of these shipwrecks have been saved, and a summary has been written for each shipwreck. Once the shipwreck has been recorded this database can be used to compare the construction elements to those from other shipwrecks.

Besides the courses, we are also part of the Maritime Archaeology Society Esbjerg (MASE), which is a student organization by students from the Maritime Programme. For MASE we are trying to organize as many things as possible for our program, mainly maritime related, which is hard because we are really busy with the courses and self-study. So far we organised a party, several film nights and a little excursion to the Ribe Viking museum, and we also visited the ruins of Riberhus castle. In May we are going to the International Viking market in Ribe, which will take place in the Ribe Viking Center. Reenactors recreate an authentic Viking market there. We are looking forward to that, and after the field school we will let you know how it was!

Commercial Diving Training at the Maritime Archaeology Programme in Denmark

On the 16th of November the commercial diving course finally started! The dive course had a duration of four weeks. Generally, course days were long with up to 12hrs of teaching or practical diving per day. 

Week 1

The first week started with a lot of theory divided over 5 days. During this week we were introduced to diving history, physics and physiology, decompression tables, legislation, dive equipment, underwater work and diving hazards, dive planning and management, diving first aid, communication and seamanship.

At the end of day 4 and 5 we went to the pool to get our first diving experience. In the pool we got familiar with all the equipment, which is quite a lot as you can see on the photos! The diving equipment we use is Interspiro MK2. In the pool we also trained basic underwater skills, like our buoyancy, and we did a mask release drill.

Week 2

After the two pool sessions it was already time for our first open water dive at Kjelst, just north of Esbjerg. In this shallow lake we spent four days of diving, doing different tasks each day. The first day was just an exploration dive.

This time we had to dive with a lifeline and a communication system, so we had to get used to that. We got instructions either via the communication system, or via rope signals. The next few days we had to do another mask drill, underwater searches, navigation with a compass, rigging (knots) and rescue drills.

At the last day of this week, we had a first aid course. Here we learned how to deal with most diving related accidents. We did CPR and did some roleplaying. At the end of the day we got our first aid certificate.

Week 3

On Sunday afternoon we left Esbjerg and went with our dive class to Hemmoor in Northern Germany. We went to a water-filled quarry, the Kreidensee, which attracts a lot of divers. In this lake traces can still be found of the quarry but also a lot of objects are submerged, like an airplane, a boat and a truck. The lake has a maximum depth of 60m. One of the goals for this week was to get used to dive to greater depths. During this week we dived to depths between 20 and 30 meters and we simulated decompression stops.

Because we stayed in houses near the dive site we had the chance to dive two times a day, in the morning usually an exploration dive at greater depth and in the afternoon a task. During this week we practiced our buoyancy, lifting objects with a lifting bag, practiced rigging (knots), rescue drills (ascent) and had to build a construction.

In the lake an airplane was emerged at around 24 meters deep, which we had to describe to the surface via communication and had to film using a camera. The last day consisted of a group assignment: we had to build a table from the metal pipes. Each pair got 45 minutes to work on the frame underwater. Once it was done, the table had to be disassembled and brought back to the surface. While lowering and lifting the pipes, we had to make sure these were well secured using the knots we learned.

Week 4

The last diving week took place in Lillebælt (Little Belt) near Fredericia, a very popular diving place in Denmark. Here we practiced more rescue drills and rigging, but we also had a new skill to train: underwater carpentry. In 30 minutes we had to make a wooden cross of 40 x 40cm. The last thing we had to do, was a visual inspection of the wall of the pier. This was also really good for practicing our buoyancy. We started at 8m depth where we had to stay for 10 minutes. Every 10 minutes we had to ascent 2m and describe the wall. There were a lot of animals (starfish, crabs, fish, jellyfish) and plants on the wall, so we had a lot to describe.

The last diving day was not in Lillebælt, but in the harbor of Esbjerg. We had the change to record a rudder from an old fishing vessel for the Fiskeri- og Søfarmuseet (Fisheries and Maritime Museum) in Esbjerg, so that they could make a reconstruction of the rudder. The description had to be drawn underwater. This was the most difficult dive we have experienced so far, because there was a very strong wind (9 on the scale of Beaufort), there was quite a strong current and the visibility was only 20-30 centimeters. We managed to get most of the measurements done, but in January we will go back to the harbor and finish the job.

The four weeks flew by and we really enjoyed this experience. Exams will take place in week 5. In this week we will have an exam on all the theory and a practical exam. In January and February a few more dive projects will (hopefully) come along, but more on this in the next blog!
