Today’s knowledge about late medieval ships is very poor, especially when it comes to caravel-built warships in northern Europe. In 1971 some sport divers found a wreck in the archipelago of Ronneby, that proved to be the Danish king Hans great ship Gribshunden, which sank in 1495. The wreck has been investigated in recent years by Kalmar läns museum and MARIS from Södertörn högskola. The research potential is from an archaeological perspective tremendous. The wreck is in very good condition compared to other finds around the world, it is unique. My intention with this thesis is to find out why the wreck hasn’t disintegrated and totally disappeared like most of contemporary wrecks. To understand the factors that are involved in the decomposition process, the wreck is analyzed with regard to Keith Muckelroy´s maritime version of “site formation process”, which presents a set of analytic tools to assess how different processes affect a wreck and its find place, both in the short and long terms. Hopefully, this thesis might be useful when it comes to find still undiscovered wrecks in similar environments.

This master's thesis is intended as a foundation for further development of methods for digital marine osteoarchaeology. The main purpose of this thesis was to examine and problematise the process of locating, documenting, and analyzing skeletal remains in marine archaeological, and other hard to reach sites. Three forms of osteological analysis' was performed and assessed: one based on analysis of physical skeletal remains, another based on 2D documented skeletal remains, and a third on analysis on 3D reconstructed skeletal remains. The secondary purpose of this thesis was to problematise the taphonomic effects on bodies, body parts, and bones in marine environments, necessary for the evaluation of the different methods. The analysis' has been conducted on source material provided by the research projects for the naval ships Mars and Gribshunden, the National Maritime Museum of Sweden, the Sandby Borg project, and the Çatalhöyük project. In addition, a test was carried out, with eight volunteer osteology students at Campus Gotland, Uppsala University, during a seminar exercise. The results collected through the osteological analysis' performed on the three different formats and the students osteology exercise could be used in order to highlight a variation of data available in the different formats. The results was then used in order to create a basis for future digital documentation methods that may be applied in the field. The secondary aim of this thesis was addressed through the use of the naval ships Mars and Gribshunden as case examples in order to address the limited amount of skeletal remains located so far at the marine archaeological sites. / Denna master uppsats är ämnad som grund för vidare utveckling av metoder för digital marinosteoarkeologi. Det huvudsakliga syftet med uppsatsen är att undersöka och problematisera problemen kring at lokalisera, dokumentera, och analysera skeletala kvarlevor vid marinarkeologiska, och andra svåråtkomliga lokaler. Tre olika slags osteologiska analyser utfördes: en baserad på analyser av skeletala kvarlevor, en annan baserad analyser av 2D dokumenterade skeletala kvarlevor, och en tredje baserat på analyser av 3D rekonstruerade skeletala kvarlevor. Det sekundära syftet uppsatsen var att problematisera den tafonomiska påverkan på kroppar, kroppsdelar, och ben i marina miljöer, nödvändiga för utvärderingen för de olika metoderna. Analyserna har utförts på källmaterial som tillgängliggjorts genom forskningsprojekten för skeppen Mars och Gribshunden, Statens Maritima Museer i Sverige, Sandby borg projektet, och Catalhöyük projektet. Utöver detta har även en studie utförts tillsammans med åtta frivilliga osteologistudenter vid Campus Gotland, Uppsala Universitet, under en seminarieövning. Resultaten som samlades in genom de osteologiska analyserna av de tre olika källmaterialen och student studien användes för att kunna understryka den datavariation som fanns tillgänglig för de olika källmaterialen. Resultaten användes för att skapa en grund för framtida digitala dokumentationsmetoder som kan appliceras i fält. Det sekundära syftet med studien besvarades genom att använda skeppen Mars och Gribshunden som exempel för att kunna diskutera den begränsade mängden skeletala kvarlevor som hittills hittats vid de marinarkeologiska lokalerna.

Marinarkeologiska föremål är en icke desto mera undersökt underkategori i museisamlingar. De skiljer sig frånandra typer av föremål i samlingar då de genom sin fyndplats är mera krävande. Det är också värt att etableravad föremålet har för värden efter utgrävningen. Som en del av värde och förmedling tas föremålenskonservering och utgrävning också upp.Genom att undersöka bärgade tre kanoner från tre vrak från perioden 1480 till 1580 ef. kr försöker uppsatsenatt belysa den typen av föremål ur flera perspektiv som går att sammanfatta ur bevarande och förmedlande.Kanonerna som undersöks är "Brisundskanonen" på Gotlands museum, en kanon från örlogsfartyget Mars ochlavetter bärgade från Gribshunden på Blekinge museum. Undersökningen är gjord genom platsbesök,intervjuer, och litteraturstudier. Målet med undersökningen är att skapa kunskap om marinarkeologiskaföremål, dess egenskaper, värden och processer. / Marine archaeological objects are an under-researched subcategory in museum collections. They differ fromother types of objects in collections as they are more demanding due to their former location. It is also worthestablishing what the object's value is after excavation. As part of value and mediation, the conservation andexcavation of the objects is also addressed.By examining three guns recovered from three wrecks from the period 1480 to 1580 AD. The essay tries to shedlight on the type of object from several perspectives that can be summarized from preservation and mediation.The cannons being examined are the "Brisund cannon" at Gotland's museum, a cannon from Mars, and lavettessalvaged from Gribshunden at Blekinge museum. The investigation is done through site visits, interviews, andliterature studies. The goal of the survey is to create knowledge of how museums best manage this type ofobject.

The aim of the MA thesis is to discuss and analyse different illustrations, paintings, carvings in wood and stone and woodcuts of ships of the new kind (Carrack, carvels), from the 15th century to the middle of the 16th century, and compare them to the Griffon-hound ship, and to understand how they have evolved. The ships of the time had large stern and end castles, three to four masts, and where built for the war tactic of boarding. The oldest ship of the new kind that have been found, is the Griffon-hound, a ship that belonged to the Danish king Hans, and sunk due to a fire 1495 outside of Ronneby in southern Sweden. Besides being the oldest of its kind, the ship also has a very specific figurehead that resembles a monster with a screaming human head in its gap. By discussing and analysing the artworks it is possible to learn more about the ships. After analysing them, the result is that the artworks do show how the ships have evolved. Some of the different attributes that the artworks display have also been found when investigating the wreck of the Griffon-hound. More attributes might still be on the wreck site, hidden under the sediment. An example is the remains of the anti-boarding nets that a lot of the artworks show, and that have been found on the wreck of the Mary Rose, the English ship that belonged to king Henry VIII. The Mary Rose is younger than the Griffon-hound, but artworks of older ships also show the anti-boarding nets, or the beams on top of the castles. The purpose behind having a large variety of different artwork is to increase the knowledge about the ships of the time, and to make sure that the attributes that is being analysed doesn’t only occur in one or two artworks.
