Eighteenth-century colonial American merchant ship constructionVanHorn, Kellie Michelle 17 February 2005 (has links)
Past research on eighteenth-century ships has primarily taken one of two avenues, either focusing on naval warship construction or examining the merchant shipping industry as a whole in terms of trends and economics. While these areas are important to pursue, comparatively little is known about actual construction techniques used on the ordinary merchant vessels of the period. Most modern sources emphasize hull design and lines drawings; contemporary sources take a similar direction, explaining the theory of ship design but often leaving out how to put the ship together. In recent years, however, new information has come to light through archaeological excavations regarding Anglo-American merchant ship construction. In this study, several of these shipwrecks were examined in light of economic factors and the literary evidence from the period in an attempt to gain a better understanding of colonial American merchant ship construction in the eighteenth century. While the data set was not large enough to make conclusive statements, this type of comparative analysis should begin to establish a
framework for the interpretation of future shipwreck excavations.

Holistic shipwreck assemblages in 14th and 15th century Southeast AsiaFahy, Brian January 2015 (has links)
The ceramic trade throughout Medieval Southeast Asia was prolific. Terrestrial sites have yielded massive amounts of ceramic material and the archaeological reports of shipwreck cargoes corroborate the versatile and extensive qualities of trade ceramics in the region. The sheer quantity of ceramic artefacts found in shipwreck assemblages, paired with a well-researched framework of the aesthetic, demonstrates that we rely heavily on ceramic data to date wrecks and establish regional trading patterns. While ceramics typically represent the bulk of the recovered material in these instances, many other types of material are present in the various assemblages. Yet these "lesser" materials suffer from a lack of investigation and, therefore, play virtually no role in the archaeological and historical assessment of the ship, its cargo, and its relationship to the maritime economy of the period. While ceramic studies may provide a general overview, a consideration of the other material provides subtlety and nuance to the analysis. This case study focuses on the non-ceramic assemblages for six shipwrecks from the 14th and 15th Centuries of Southeast Asia (three Chinese-built and three Southeast Asian-styled junks). The typological study of the metallurgical, organic and geological material from these wrecks can complement much of the work surrounding existing trade models as well as reveal new concepts of crew life, belief systems and culture. These facets come together to offer a more holistic narrative as well as stimulating the need within the region for more study regarding the locations where past peoples mined and manufactured raw metals. The thesis will also consider the motivations behind the excavators of these projects and what role this plays in the interpretation of the non-ceramic material. One wreck was excavated by treasure hunters, one was done by an amateur archaeologist and a curator, and a third was excavated by a governmental organization. Two excavations were conducted by a non-profit foundation in conjunction with a National Museum and a final one was a purely academic excavation. Each party brings their own experiences and motivations to the excavation and therefore the systems of collection, curation, and conservation weigh heavily and are varied. These factors can determine what priorities each excavator brings to the analysis of excavated objects and the extent to which this effects the subsequent interpretation of the shipwreck.

The long term impact of the Seli One shipwreck on the Table Bay beachesSeifart, Christian 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: On the 9th September 2009, the 178 m Panamanian bulk carrier, the Seli One, ran aground off the coast of
Blouberg in Table Bay, South Africa. Due to failed salvage attempts, the vessel has remained stranded
approximately 500 m off the Blouberg beachfront. Since the vessel ran aground, a gradual change in the
Blouberg beach shape in the lee of the wreck has been observed. The local coastline, which has traditionally
been fairly uniform, has assumed a curved shape, with significant sediment accretion being observed in the
wave shadow of the wreck. Initially, the Seli One wreck remained intact. However, during a storm on the 4th
September 2011, the vessel split up into three separate pieces.
The impact that the wreck is having on the local wave, current and sediment transport dynamics remains
undefined. This lack of knowledge results in significant risks, relating to shoreline stability and beach amenity.
The objective is this study was therefore the determination of the long-term impact of the Seli One shipwreck
on the Blouberg beachfront.
A review of existing literature has indicated that no empirical relationships are available which could be used
to calculate the impact of a shipwreck on nearby coastal processes. Numerous methods are available which
can be used to determine the net longshore transport rates, but these cannot be used to quantify the impacts
of shipwrecks on the local sediment transport regime. Numerical models were therefore used to determine
the impact of the Seli One shipwreck.
Through the analysis of simulation results, it was concluded that, as expected, the shipwreck has resulted in a
significant reduction in the net longshore sediment transport rate in her lee, resulting in sediment deposition
in this area. It was further concluded that the vessel does not result in the complete blockage of longshore
sediment transport, and that sediment is able to periodically pass through the lee of the vessel.
The simulated beach salient on the 3rd July 2011 was compared to results of a beach survey, performed on the
same date specifically for this study. The simulated accretion of approximately 27 m in the lee of the
shipwreck agrees well with the measured salient. It has been shown that approximately 75% of the salient
accretion occurred within the first two months of the vessel’s arrival. Furthermore, shoreline erosion on the
northern side of the salient resulting directly from the shipwreck has been shown to be approximately 15 m.
This too occurs relatively rapidly, within approximately two months of the vessels arrival.
Following the initial impact of the wreck in its intact configuration, the long-term potential impact of the vessel
in its broken-up configuration was determined. This included the assumption that the vessel does not undergo
any additional breaking-up, and remains in its three-piece configuration indefinitely. This has shown that the
salient width resulting from the shipwreck is reduced to approximately 20 m, compared to the initial 27 m.
However, shoreline erosion on the northern side of the wreck has increased from approximately 15 m initially
to approximately 18 m in the long-term, which is caused by the continuous sedimentation between the vessel
and the beach.
A two-dimensional coupled wave, current and sediment transport model has been developed and has shown
that the wave shelter resulting from the Seli One results in the formation of a submerged salient between the
vessel and the shoreline.
It was found that shipwrecks have the potential of significantly altering local longshore sediment transport
characteristics in general. Depending on local conditions, this may pose serious risks, both in terms of
jeopardizing local seaside infrastructure, as well as creating dangerous swimming conditions.
Considering the impact that a shipwreck can have on local shoreline changes, with special regard to the rate at
which these shoreline changes can occur, it is recommended that the results obtained from the current study
be used to estimate the impact of potential future shipwreck scenarios in Table Bay. / AFRIKAANSE OPSOMMING: Op die 9de September 2009 het die 178 m lange Panamese vragskip, die Seli Een, aan die kus van
Bloubergstrand in Tafelbaai, Suid Afrika, gestrand. Weens mislukte reddingspogings, het die skip ongeveer 500
m van die kuslyn gestrande gebly. Sedertdien, is ‘n geleidelike verandering in die vorm van Bloubergstrand se
kuslyn waargeneem. Die kuslyn, wat tradisioneel redelik uniform en reguit was, het onlangs ‘n aansienlike
geboë vorm aangeneem, met ‘n beduidende hoeveelheid sand wat in die skip se lykant neerset. Aanvanklik
het die Seli Een wrak ongeskonde gebly, maar tydens ‘n storm op die 4de September 2011, het die skip in drie
afsonderlike stukke opgebreek.
Die impak wat die wrak op die golf, strome en sediment vervoer dinamika het,bly ongedefinieërd. Hierdie
gebrek aan kennis veroorsaak ‘n aansienlike hoeveelheid risiko’s met spesifieke betrekking tot kuslyn stabiliteit
en strand gerief. Die doel van hierdie studie was dus om die langtermyn-impak van die Seli Een skeepswrak op
Bloubergstrand te bepaal.
'n Hersiening van bestaande literatuur het aangedui dat geen empiriese verhoudings beskikbaar is wat gebruik
kan word om die impak van 'n skeepswrak op die nabygeleë kustelike prosesse te bereken nie, maar wel
versekeie metodes wat gebruik kan word om die netto langsstroom sediment vervoer te bepaal. Hierdie
verhoudings kan egter nie gebruik word om die impak van ‘n skeepswrak op die sediment vervoer meganisme
te kwantifiseer nie, dus is numeriese modelle gebruik om die impak van die Seli Een skeepswrak te bepaal.
Die skeepswrak het ‘n aansienlike vermindering in the netto langsstroom sediment vervoer veroorsaak, wat
tot die afsetting van sediment in hierdie gebied lei. Dit is ook verder bepaal dat die Seli Een nie die volledige
verstopping van langsstroom sedimentvervoer veroorsaak nie, maar dat sediment van tyd tot tyd in staat is om
deur die lykant van die skeepswrak te beweeg.
Die gesimuleerde strand aanwas van die 3de Julie 2011 is vergelyk met resultate van ‘n strand-opmeting, wat
uitgevoer is op dieselfde datum, spesifiek vir hierdie studie. Die gesimuleerde aanwas, van ongeveer 27 m in
die lykant van die skeepswrak, stem saam met die gemete aanwas. Ongeveer 75% van die aanwas het binne
twee maande van die aankoms van die Seli Een plaasgevind. Verder is dit getoon dat aan die noordelike kant
van die aanwas, ongeveer 15 m van die kuslyn weggespoel het as gevolg van die Seli Een.
Na die aanvanklike impak van die wrak in sy ongeskonde konfugirasie, is die potensiële langtermyn impak van
die skip in sy opgebreekte konfugirasie bepaal. Dit sluit die aanname in dat die skip nie enige bykomende
breke ondergaan nie, en in sy drie-stuk konfigurasie bly. Dit het getoon dat die breedte van die aanwas, wat
veroorsaak is deur die skip, verminder tot ongeveer 20 m in vergelyking met die aanvanklike 27 m. Verder is
dit getoon dat die erosie aan die noordelike kant van die Seli Een vermeerder het van die aanvanklike 15 m na
ongeveerder 18 m in die langtermyn. Die oorsaak hiervaan is die aaneenlopende sedimentasie tussen die
wrak en die strand.
'n Twee-dimensionele gekoppelde golf, stroom en sediment vervoer model is ontwikkel en het getoon dat die
golf skuiling, as gevolg van die Seli Een, sedimentasie tussen die skip en die kuslyn veroorsaak.
Daar is gevind dat skeepswrakke die potensiaal het om aansienlike veranderinge aan die nabygeleë langstroom
sediment vervoer stelsel te veroorsaak. Afhangende van die plaaslike omstandighede, kan hierdie ernstige
risiko’s veroorsaak, beide in terme van die gevaar vir plaaslike kustelike infrastruktuur, sowel as die generasie
van gevaarlike swem toestande.
Met inagneming van die impak wat 'n skeepswrak op plaaslike kuslyn veranderinge kan hê, met spesiale
verwysing na die tempo waarteen hierdie kuslyn veranderinge kan plaasvind, word dit aanbeveel dat die
resultate wat verkryg is vanuit die huidige studie, gebruik word om die impak van moontlike, toekomstige
skeepswrakke in Tafelbaai te bepaal.

Geophysical Mapping around Björkö Island in Lake Mälaren, South central SwedenFransner, Oscar January 2013 (has links)
The former Viking settlement Birka is located on Björkö Island in Lake Mälaren, the third largest lake in Sweden. Birka is a well-known archeological site that onshore has been carefully examined. The lake floor of the waters surrounding the island has been less investigated but has a great potential to host not yet discovered archeological objects from this former hub for seafarers. Therefore, a geophysical survey including multibeam sonar mapping and subbottom profiling was carried out mainly along the shores of western Björkö Island. Processing and analysis of these collected data form the basis of this thesis. The main aims of this study are to produce a suite of geological maps and stratigraphic profiles that are used to geologically interpret the uppermost sediment stratigraphy and the bathymetry of the area. In addition, the processed data are investigated for archeological objects. The result shows that the acoustic records of the sediment stratigraphy reaches back to glacial clay formed as a consequence of the retreat of the Late Weichselian ice sheet, and that the uppermost sediment units probably are from the time after the isolation of Lake Mälaren from the Baltic Sea. The bathymetry and backscatter results have revealed that this relatively shallow study area contains several objects that potentially could be of interest from an archeological point of view. These objects include several unidentified objects in the Björkö strait and two unregistered shipwrecks where ground truthing data need to be collected to determine their respective origin.
