The archaeological remnants of coastal ports and shipwrecks serve as invaluable heritage sites that provide profound insights into historical maritime activities conducted by humans. Cross-regional voyages occurred as early as the beginning of the first millennium, aided by the increasing knowledge of the monsoons. Along with expanding intra- and inter-sailing routes, the improved seaworthiness of vessels facilitated the movement of people and seaborne commodities. The names of the Indic, Kunlun, and Persian ships appear in various historical accounts written in the latter half of the first millennium, and the structural details and characteristics can be physically examined by looking at shipwrecks. Southeast and East Asian shipwrecks from the eighth to the fourteenth century provide a perspective on the dynamism of types of seagoing ships involved in long-distance trade. By examining the remnants of cargo being transported by these ships, we begin to understand how the system of cross-regional shipment of heavy and bulky items, metal objects, fragrant woods, glass, and ceramics sustained and impacted the religions, societies, culture, and regional economies. Furthermore, it helps define the Maritime Silk Route heritage to be managed and protected. As such, this paper gives the archaeological evidence of port ruins and wrecks and also introduces, as an example, a case from Central Vietnam.

In this study, samples were collected from various ancient wooden shipwrecks, including the Shinan shipwreck and Jindo shipwreck that used iron nails, the Yeongheungdo shipwreck carrying iron artifacts, as well as the Sibidongpado shipwreck and Wando shipwreck where degradation products were not observed, all of which were salvaged by the National Research Institute of Maritime Heritage. The aim was to analyze the characteristics of degradation products generated by iron (Fe) within the salvaged wooden shipwreck materials and establish fundamental data on degradation products in waterlogged archaeological wood. The analysis revealed that sulfur (S) is generally accumulated in wood obtained from marine environments. It was observed that the content of inorganic substances such as iron and sulfur was significantly higher in the Shinan shipwreck, Jindo shipwreck, and Yeongheungdo shipwreck compared to Sibidongpado shipwreck and Wando shipwreck, which used wooden nails. This indicates that the presence of iron affects the accumulation of degradation products and suggests that iron is a factor in the corrosion of wood. Furthermore, crystallin compounds were observed within the cell walls, and higher concentrations of iron and sulfur were found in the resin ducts, rays, and radial tissues. This suggests that during desalination and consolidation treatments, warm water or polyethylene glycol (PEG) may move degradation factors into resincanals, rays, radial tissues, etc.

Marine accidents show various causes and effects in Korea where 3 sides of the country are surrounded by the ocean. Every year, 600 to 700 marine accidents occur mostly by small fishing boats. There are repeated accidents which involve crashes of coastal ships with fishing boats, which produce casualties and massive environmental hazard and the need for underwater search for shipwrecks. From the beginning of 21st century, the decrease of large ships with large number of crews led to the emergence of digitalvessels and the digital data storage of the installed equipments on the vessels, marine digital forensic - the extraction and analysis of the stored digital data within digital vessels - became necessary. This article is intended to suggest marine digital forensics as a solution of collecting evidence for discovering the causes, liabilities and compensations of marine accidents.

Cultural property Preservation Bureau of Korea excavated the massive shipwreck and her cargo from 1976 to 1984 sunken under Jeungdo Island, Sinan County located int eh southwest area of the Korean peninsula. It was the first systematic underwater excavation in Korea, and one of the richest underwater discovery int eh world. According to the reference materials, more treasure shipwrecks are assumed to be sunk under seaside of Korean peninsula. Such as, Donskoy near Ulleung Island, Kow Shing near Ul Island, and yamashita treasure ship off Korean peninsula, etc. The excavations of these treasure ship are likely to raise ownership dispute between private finders and government authority, and between ship owner and excavater due to lack of knowledge and awareness of related laws and regulation. Therefore, this study aims to examine existing legal regimes related to the excavated treasureship. And also it tries to suggest a new proactive measure to prevent the most likely ownership disputes between interested parties.

This study examined the food culture of the Koryo Dynasty during the early 13th century based on the records of wooden tablets and marine relics from the 1st and 2nd ships of Mado wrecked at sea off Taean while sailing for Gaegyeong containing various types of grain paid as taxes and tributes. The recipients of the cargo on the 1st ship of Mado were bureaucrats living in Gaegyeong during the period of the military regime of the Koryo Dynasty, and the place of embarkation was the inlet around Haenam (Juksan Prefecture) and Naju (Hoijin Prefecture) in Jolla-do. On wooden tablets were recorded 37 items of rice, cereal, and fermented foods. The measures used in the records were seok [石-20 du (斗)] for cereal, seok [15 du, 20 du] for fermented soybean paste, and pot (缸) and volume (斗) for salted fish. The places of embarkation on the 2nd ship of Mado were Jeongeup (Gobu Prefecture), Gochang (Jangsa Prefecture, Musong Prefecture), etc. On wooden tablets were recorded 29 items of rice, cereal, fermented foods, seasame oil, and honey. The volume measure for yeast guk (麴), the fermentative organism for rice wine, was nang [囊-geun (斤)], and the measure for sesame oil and honey, which were materials of oil-and-honey pastries and confections, was joon (樽-seong, 盛). Honey and sesame oil were luxury foods for the upper-class people of the Koryo Dynasty, and they were carried in high-quality inlaid celadon vases in Meibyung style. Food names and measures written on wooden tablets and actual artifacts found in the 1st and 2nd ships of Mado are valuable materials for research into agriculture, cereal, and fermented foods of the Koryo Dynasty in the early 13th century. Besides, relics such as grains and bones of fish and animals from the Koryo Dynasty are expected to provide crucial information usable in studies on food history of the Korean Peninsula.

Underwater photographing and image recording are essential for pre-excavation survey and during excavation in underwater archaeology. Unlike photographing on land, all underwater images suffer various quality degradations such as shape distortions, color shift, blur, low contrast, high noise levels and so on. Outcome is very often heavily photographing equipment and photographer dependent. Excavation schedule, weather conditions, and water conditions can put burdens on divers. Usable images are very limited compared to the efforts. In underwater archaeological study in very turbid water such as in the Yellow Sea (between mainland China and the Korean peninsula), underwater photographing is very challenging. In this study, off-site image distortion and color compensation techniques using an image processing/analysis software is investigated as an alternative image quality enhancement method. As sample images, photographs taken during the excavation of 800-year-old Taean Mado Shipwrecks in the Yellow Sea in 2008-2010 were mainly used. Significant enhancement in distortion and color compensation of archived images were obtained by simple post image processing using image processing/analysis software (PicMan) customized for given view ports, lenses and cameras with and without optical axis offsets. Post image processing is found to be very effective in distortion and color compensation of both recent and archived images from various photographing equipment models and configurations. Merits and demerit of in-situ, distortion and color compensated photographing with sophisticated equipment and conventional photographing equipment, which requires post image processing, are compared.

Joseph Mallord William Turner (1775-1851) has been widely regarded as the most original and brilliant English landscape painter in the 19th century. Admitted to the Royal Academy Schools in 1789, Turner was a precocious artist and gained the full membership of the prestigious Royal Academy in 1802 at the age of 27. Already in the 1800s he was recognised as a pioneer in taking a new and revolutionary approach to the art of landscape painting. Among his early works made in this period, The Shipwreck, painted in 1805, epitomizes the sense of sublime Romanticism in terms of its dramatic subject-matter and the masterly display of technical innovations. Of course, the subject of shipwreck has a long standing history. Ever since human beings first began seafaring, they have been fascinated as much as haunted by shipwrecks. For maritime societies, such as England, shipwreck has been the source of endless nightmares, representing a constant threat not only to individual sailors but also to the nation as a whole. Unsurprisingly, therefore, shipwreck is one of the most popular motifs in art and literature, particularly during the 18th and 19th centuries. Yet accounts, images and metaphors of shipwreck have taken diverse forms and served different purposes, varying significantly across time and between authors. As such, Turner's painting registers a panoply of diverse but interconnected contemporary discourses. First of all, since shipwreck was an everyday occurrence in this period, it is more than likely that Turner's painting depicted the actual sinking in 1805 of the East India Company's ship 'The Earl of Abergavenny' off the coast of Weymouth. 263 souls were lost and the news of the wreck made headlines in major English newspapers at the time. Turner's painting may well have been his visual response to this tragedy, eyewitness accounts of which were given in great quantity in every contemporary newspaper. But the painting is not a documentary visual record of the incident as Turner was not present at the site and newspaper reports were not detailed enough for him to pictorially reconstruct the entire scene. Rather, Turner's painting is indebted to the iconographical tradition of depicting tempest and shipwreck, bearing a strong visual resemblance to some 17th-century Dutch marine paintings with which he was familiar through gallery visits and engravings. Lastly, Turner's Shipwreck is to be located in the contexts of burgeoning contemporary travel literature, especially shipwreck narratives. The late 18th and early 19th century saw a drastic increase in the publication of shipwreck narratives and Turner's painting was inspired by the re-publication in 1804 of William Falconer's enormously successful epic poem of the same title. Thus, in the final analysis, Turner's painting is a splendid signifier leading the beholder to the heart of Romantic abyss conjoing nightmarish everyday experience, high art, and popular literature.

Shipwreck remains below the seabed not only effect the ocean currents and tides, but influence the physical properties of sediments and sedimentary environments that comprise the seabed. In particular, the influence of local shipwrecks discovered buried in the seabed on the sediment is visible. In this study, sediments were collected from the surrounding area of Taean Mado No.3 shipwreck using grab samplers and vibro-corers. The physical properties of these sediments were analyzed to evaluate the impact of the Taean Mado shipwreck No.3 remains. Sediment core analysis by means of density and ultrasonic velocity showed that shear strength tended to increase with depth, whereas moisture content and porosity tended to decrease with depth. Grain size analysis results are shown in terms of Folk's classification, where the grain size of the core samples in the study area indicate mud or sandy mud, and that of the grab sample indicates a muddy sand. Results of the sedimentation rate analysis indicate a rate of 2.84 cm/year and carbon dating of the 150 cm deep seashell indicates the Neolithic age. These sediments were analyzed for the study of the relationship between the Taean Mado shipwreck No.3 remains and the physical properties of the sediment.

From 2007 to 2011, four Goryeo Dynasty vessels, namely the Taean treasure ship, Taean Mado Shipwreck No.1, No.2, No.3 were discovered in Taean area, Chungcheongnam-do province. From the shipwrecks, 175 pieces of mokkan (wooden tablet) were excavated. These mokkans are the only case of Goryeo Dynasty and represent the unique usage of mokkan as cargo tags, after the paper replaced the wooden tablets as writing materials. The Taean mokkans provide details, such as the year, recipient, port of origin, types of the cargo, quantity and unit, the name of the responsible person for shipment. Thus, they enable us to speculate about the characteristics of the cargo. Furthermore, through studying the writing style, form, material and manufacturing method, researchers can extract which form and characteristics were favored at that time. The Taean mokkans have no preset style for writing. Therefore, they can be written selectively and freely. And since the mokkan were attached to cargos, mokkans with furrows on upper side were favored, and efficiency and simplification of the manufacturing process were priorities in making mokkans. The Taean mokkans can be compared to those from the Shinan ship and the Quanzhou ship because those are of the same era and use. On the writing styles and information, Chinese mokkans are focused on the cargo owners, while The Taean mokkan includes more detailed information, such as the recipients. In forms, Chinese mokkans have maximum thickness of 1.0 centimeter and have pointed edges in lower parts, while mokkans from Taean do not have fixed thickness or edges. Furthermore, Chinese mokkans and Korean mokkans have different styles from manufacturing methods and material selections. These differences between Chinese and Goryeo mokkan are related to the differences between littoral-transport Goryeo ships and ocean-transport Chinese ships, such as shipping distances, types of cargo, shipping systems, packing methods, and transport operators. At the moment, because there are only small amount of data and materials of Chinese mokkan, comparative studies regarding Goryeo and Chinese mokkan can only be fragmentary. However, this article can be a base from which to expand the scope of Goryeo mokkan studies.
