My Writings. My Thoughts.
Over the last two days the survey south of the structure for anomalies has been completed using the circular searches south of each box and the recording for all the timbers which have been lifted has been completed. The anomalies south of the structure are mainly loose timbers and vertical poles, the purpose of these are still to be determined.
The next step was to survey boxes 7 and 8 to obtain more detailed information of the layout of the timbers and construction of the box. As box 7 proves to be particularly interesting, with a ‘balcony’ construction on the south side, this has been chosen for excavation and blueview later in the week, including the corner of box 8 to obtain more information of how these two boxes are connected.
The last two days we have continued searching the area just south of the structure and working our way down the boxes using circular searches to look into the line of debris shown in the side scan data and lifting timbers for recording on land which seem to show significance. These searches have proven very effective, a sinker and reel line have been used to do varying circular distances and so far 9 timbers have been lifted…unfortunately a storm came in this afternoon which cut our day short. We have lifted timbers which all display a very different purpose; some are vertical poles which may possibly be for further defence and also planks and beams which may be part of the side or the top of the structure.
Another beautiful day in Schleswig was used to take a closer look –or rather feel- of the structure. The question was: what is going on South of the structure? With a line tied to a sinker and the diver holding on at the other end, the area was searched first one meter from the sinker, two meters, three and four. What we found shed light on the construction of the structure and answered some of our questions regarding how the structure was held together. The timbers that were found were retrieved and transported to shore, tagged, photographed, recorded and set aside for further recording if necessary.
All in all a very productive day with a boat team and total station team working very well together and we were provided with new information on the Schleswig Barrier.
Only one minor problem….to see the boat being paddled in by the team at the end of the day! Apparently the fuel ran out about half way back to the rowing club, but luckily Team B’s boat came along and gave them a tow!

The dives started early with the sun shining! Unfortunately a local fisherman picked up our bouy overnight…later to hand it back to us today to explain there was no name and we should make it clear that we are doing archaeological work and would like the bouy to remain there! As a result the first diver had to relocate the structure, but this was no problem as Kostas placed us right ontop of the structure and we were back to exploring the structure in no time!
Team A (MAP team) focused on the western part of the structure working inwards towards Team B (Kiel team) who were working inwards from the Eastern part of the structure. Overall 7 small numbered bouys are now attached and exploration has begun on the interesting timbers forming a balcony shape on box 7 and detailed descriptions of box 16 have been completed. This was achieved by a surface swimmer with a prism attached to a pole and bouy which goes down to the diver on a rope; the diver then places the rope pulled tight ontop of the timber to be shot by the total station. This is intergrated into QGIS using a plugin in real time for these points to be relayed to the surface team to direct the diver in further exploration.
The multibeam data is the most accurate and is now being used as the background image for the land team when points are shot on the structure.
Most team members have now been diving and have gotten used to the zero visibility and the sediment and the need to dig for burried timbers when following the structure. What has been noticed since Jens got into the water today is that a new layer of very soft sediment as collected since the last field school in June 2014, about 10cm in places.
The next step for tomorrow is to explore further south and begin mapping the anomalies and loose timbers with detailed descriptions and possibly lifting loose timbers to see the contruction methods and record on the surface in greater detail.
It was a gorgeous day here in Schleswig and the sun stayed shining all day! The group set out early today, one team out on the boat to start familiarisation dives with the submerged structure and the other group out to set up and orientate the total station so that we can start shooting points once exploration of the structure begins. This will allow the surface team to monitor and help position the divers along the structure.
With divers slowly getting used to the zero visibility and describing every movement, we have started to place where we are on the structure in relation to the work done last year and have begun exploring the loose timbers surrounding a unique box in the middle of the structure, box 7. We should be all set to start shooting points on these loose timbers tomorrow and explore further to hopefully map more of the structure and anomalies.
The group arrived yesterday afternoon after a short drive from Esbjerg down across the border to Schleswig where we are kindly being hosted by the Schleswig Rowing Club. Everything unpacked, briefed, set up and tested, then out for some dinner and mojitos, after all…today was a non-diving day!
After launching the boats, the morning was spent briefing the team from Kiel University, introducing them to our diving equipment and the GIS platform that we will be working from this month. The afternoon was then spent at the Landesamt with a presentation by Eicke Siegloff on the integration of finds, fieldwork and documentation and the development of their software Archaeodox. With the dive plan in place, we are all prepped for the diving to start in the morning!
Last week our second year maritimers got the opportunity to know more about the Nationalmuseet’s conservation department with regards to wooden archaeological finds of a maritime nature. The class visited the storage facilities, discussed how finds are handled, treated and cared for, as well as learned more about Danish and European projects which aim at managing underwater sites.
A big thank you to Kristiane Strætkvern and Anne-Marie Eriksen for taking the time to show us the conservation centre and their presentations during our visit to Brede.
