Archaeological Survey of the Ex-USS <Emphasis Type="Italic">Independence</Emphasis> (CVL22)

In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep-water (829 m) wreck of the ex-USS Independence (CVL22) using the remotely operated vehicles Argus and Hercules. The survey provided 34 h of direct observation with video and still camera documentation of the wreck, which the previous year had been initially identified with a limited three-dimensional sonar survey of the site. The 2016 assessment added considerably to an understanding of changes to Independence after its use as a target vessel for the 1946 atomic bomb tests at Bikini Atoll, as a radiological laboratory, training facility, and finally as a receptacle for “nuclear waste” prior to its scuttling off California in January 1951. The location and detailed examination of the wreck, along with additional archival research, offers a more nuanced definition of the carrier’s role within the context of the Cold War between the USSR, its adversaries and the race to establish nuclear supremacy, as well as site formation processes and ongoing biological colonization of the wreck site. As well, no evidence of residual radiological contamination was noted during the mission.     

Mine blast vibration response spectrum for structural vulnerability assessment: case study of heritage masonry buildings

Ground-borne vibrations induced by mine blasting are typically of low amplitudes, which are not considered a major concern for modern engineered structures. However, historic structures are often considered more vulnerable due to inadequate knowledge regarding the state of construction materials and structural response. Specifically, the construction materials used might be fragile or have deteriorated to a stage that could be vulnerable to such vibrations. Simplistic rule based on peak ground motion parameter has been adopted worldwide for safety assessment, while the frequency characteristics of vibrations are not taken into account. Further, there is very limited study on response of heritage structures to near-field blasting. This article presents a practical structural vulnerability assessment method for mine blast-induced vibrations. In particular, a design response spectrum model is proposed based on close range measurements of nearby mine blasting, which is compared with an existing design spectrum model for far-field mine blasts and a typical design spectrum model for earthquake actions. The method is illustrated through a case study of heritage masonry buildings in Australia. The unique blast data presented and the generalized methodology would be useful to both structural engineers and blast engineers in considering potential effects of blasting on heritage structures.     

USS <Emphasis Type="Italic">Independence’s</Emphasis> Aircraft

Submerged aircraft are a newly emerging area of study in underwater archaeology. In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep water (829 m) wreck of the ex-USS Independence (CVL22), a WWII era light carrier scuttled off San Francisco after its use as an atomic bomb test target and subsequently as a floating radiological laboratory and training facility. Using the remotely operated vehicles Argus and Hercules, the expedition documented and studied Independence including assessment of a sonar target thought to be an aircraft resting inside the sunken carrier’s forward elevator pit. The survey confirmed the presence of a plane, but previous assumptions as to the type and identity of this aircraft, based on archival records, proved erroneous. As well, the remains of a second, and possibly a third, aircraft were also encountered during the 2016 survey. These artifacts, through their context, both as naval warplanes on an aircraft carrier, and as test articles for seaborne nuclear weapons development, more precisely fit within the parameters of maritime archaeology. They join other archaeological evidence at the Independence site that helps define its significance within the context of World War II and the Cold War.     

Organization of ceramic production at a fortified Early Bronze Age settlement in Moravia (Czech Republic) inferred from minimally destructive archaeometry

This paper explores how pottery production was organized at fortified sites of central Europe at the end of the Early Bronze Age. The organization of pottery production in terms of ethnography-based models was inferred jointly by non-destructive multi-elemental analysis, micropetrography and powder X-ray diffraction. This minimally destructive approach was used to explore the mode of pottery production at the fortified central site Blu?ina (Moravia, Czech Republic). Archaeometry-based indirect evidence indicates that tableware of a specific shape was produced using a specific technology at the site or in its close vicinity and that coarse ware was brought to the site from elsewhere. The results obtained were complexly evaluated and compared with ethnography-based categorizations to reveal the features of production organization of the Early Bronze Age pottery. Multidimensional analysis classified the production as intensified household labour and work of individual retainers, or nucleated corvée, depending on its scale and intensity.     

Unraveling a Neanderthal palimpsest from a zooarcheological and taphonomic perspective

Practically all archeological assemblages are palimpsests. In spite of the high temporal resolution of Abric Romaní site, level O, dated to around 55 ka, is not an exception. This paper focuses on a zooarcheological and taphonomic analysis of this level, paying special attention to spatial and temporal approaches. The main goal is to unravel the palimpsest at the finest possible level by using different methods and techniques, such as archeostratigraphy, anatomical and taxonomical identification, taphonomic analysis, faunal refits and tooth wear analysis. The results obtained are compared to ethnoarcheological data so as to interpret site structure. In addition, activities carried out over different time spans (from individual episodes to long-term behaviors) are detected, and their spatial extent is explored, allowing to do inferences on settlement dynamics. This leads us to discuss the temporal and spatial scales over which Neanderthals carried out different activities within the site, and how they can be studied through the archeological record.     

Scattered shipwreck site prospection: the combined use of numerical modeling and documentary research (<Emphasis Type="Italic">Fougueux</Emphasis>, 1805)

A shipwreck site located off Sancti Petri sand spit (Cadiz, Spain) was identified as a Temeraire-class 74-gun French ship. The archaeological deposits relate it to the Fougueux, sunken after the Battle of Trafalgar. The site contains some pieces of the naval structure, 32 iron guns, and a large anchor, but two thirds of the ship is missing. Available information (including ship logbooks of weather observations and other historic documents) establishes that a dismasted French ship ran aground on 22 October 1805 and broke up into pieces on the 25th due to tempestuous weather. Combining that information and a set of numerical models (ocean, atmosphere, and dispersion), we aim to simulate different scenarios in order to determine the most probable areas for finding the shipwreck remains of the Fougueux, taking into account the uncertainty of the information used and the modeling limitations. The probability of finding scattered remains belonging to the Fougueux was calculated using the modeled scenarios. As a result, it was found that the high probability area contained four additional sites comprising 40 guns and 5 anchors whose characteristics and dating are similar to those of the previously known site. The results of our study highlight the value of numerical modeling in underwater archaeology as a tool for the identification and optimization of resources in prospecting scattered shipwreck sites.     

Austro–Hungarian refugee soldiers in China

ABSTRACT

This paper deals with the problem of the Austro–Hungarian prisoners of war in World War I who were captured by the Russian Army and who then escaped from Siberian detention camps and ultimately found asylum in China. The Tianjin German Relief Fund (Tientsin Hilfsaktion) was a leading nongovernmental charitable organization that provided aid for these captives and refugees. It operated successfully in China until that country’s decision to join the war on the side of the Allied Powers forced the organization to close. A local network of German and Austro–Hungarian civilian middlemen also helped the refugee soldiers passing through, and the Chinese authorities set up camps in Manchuria for these soldiers, where they were interned until their repatriation after the war. This paper also introduces some individual cases to show how certain Austro–Hungarian POWs attempted to deal with their life in China. The author argues that China had a role and agency in World War I, that the refugee soldier question was the last episode of the nineteenth-century-style Concert of Europe, and that the POWs had a role and agency in shaping their own destinies.     

The shrinkage cracks and the diameter of the log: a experimental approach toward fuel management by Patagonian hunter-gatherer (Paredón Lanfré site. Río Negro Province,Argentin)

The anthracological study of Paredón Lanfré (Patagonia, Argentina) highlights the presence of radial cracks with a marked difference between the percentage of affected coniferous charcoal (Fitzroya cupressoides and Austrocedrus chilensis) compared to the angiosperms (e.g., Nothofagus antarctica and Nothofagus dombeyi). The aim of this work was to obtain experimental comparison data from two Patagonian conifers to understand the prehistoric combustion behavior of the region. These results showed a discrepancy between the average of shrinkage cracks made with green wood fires and those with dry wood fires. The study of the caliber of charcoal recovered from Paredón Lanfré showed significant differences between the samples of F. cupressoides and A. chilensis. The calculation of correlation between size and shrinkage cracks suggests for both species that the size is not related to the number of registered shrinkage cracks in charcoal studied. Therefore, the gauge would not be a variable which could influence the presence of shrinkage cracks in the charcoal. Consequently, the difference of average shrinkage cracks between the two specimens may result from another variable that remains to be identified.     

Urbanization in Iron Age Europe: Trajectories,Patterns, and Social Dynamics

The development of the first urban centers is one of the most fundamental phenomena in the history of temperate Europe. New research demonstrates that the earliest cities developed north of the Alps between the sixth and fifth centuries BC as a consequence of processes of demographic growth, hierarchization, and centralization that have their roots in the immediately preceding period. However, this was an ephemeral urban phenomenon, which was followed by a period of crisis characterized by the abandonment of major centers and the return to more decentralized settlement patterns. A new trend toward urbanization occurred in the third and second centuries BC with the appearance of supra-local sanctuaries, open agglomerations, and finally the fortified oppida. Late Iron Age settlement patterns and urban trajectories were much more complex than traditionally thought and included manifold interrelations between open and fortified sites. Political and religious aspects played a key role in the development of central places, and in many cases the oppida were established on locations that already had a sacred character as places for rituals and assemblies. The Roman conquest largely brought to an end Iron Age urbanization processes, but with heterogeneous results of both abandonment and disruption and also continuity and integration.
