Quantifying shallow-buried maritime archaeological material using SBP acoustics: Experimental and in-situ wrecksite survey approaches

Examples of wetland deposits can be found across the globe and are known for preserving organic archaeological and environmental remains that are vitally important to our understanding of past human–environment interactions. The Mesolithic site of Star Carr (Yorkshire, United Kingdom) represents one of the most influential archives of human response to the changing climate at the end of the last glacial in Northern Europe. A hallmark of the site since its discovery in 1948 has been the exceptional preservation of its organic remains. Disturbingly, recent excavations have suggested that the geochemistry of the site is no longer conducive to such remarkable survival of organic archaeological and environmental materials. Microcosm (laboratory-based) burial experiments have been undertaken, alongside analysis of artifacts excavated from the site, to assess the effect of these geochemical changes on the remaining archaeological material. By applying a suite of macroscopic and molecular analyses, we demonstrate that the geochemical changes at Star Carr are contributing to the inexorable and rapid loss of valuable archaeological and paleoenvironmental information. Our findings have global implications for other wetland sites, particularly archaeological sites preserved in situ.

CERAMIC STAMPS FROM VILINO (RASSADNOE) — IN PERIODIZATION AND CHRONOLOGY OF THE SITE (SOUTH-WESTERN CRIMEA)

This paper is devoted to the publication of amphora stamps discovered during excavation at the settlement of Vilino (Rassadnoe) in 2008—2014. During the research of the settlement the eastern border of the ancient estate and the main chronological framework of the settlement life were ascertained. The stone monumental structure was discovered in 2008. This is the cistern for collecting and storage of rainwater. In the Late Scythian time it was used as a burial structure (crypt). Ceramic stamps found at the site are represented by such centers as Sinopa, Chersonesos, Rhodes. Unfortunately not all of them were discovered in the cultural layers (in situ) and some were found in disturbed layers, at the surface or in the looter’s holes. Nevertheless, with a lesser or greater degree of probability, it’s possible to correlate them with the chronology of the settlement and periods of its life. On the excavated areas of the site four building periods (A—D) were observed — two Classic and two Late Scythian. The first period is associated with the time of activity of the Greek fortified estate (Chersonesos Сhora) from the last quarter of the 4th to the early 3rd century BC. In the second period, after a break, the population has come back to the settlement in the last quarter of the 3rd century BC. There was the period of recolonization during which the restructuring of the settlement has carried out. At the end of the first quarter of the 2nd century BC the life at the settlement was stopped. The next two periods correspond to the Late Scythian culture. However, the layers and building remains of the late 2nd century BC — 1st century AD was destroyed by plowing and looter’s holes. The upper horizon of the settlement contains the material from the 1st—3rd centuries AD. The stamps and other archaeological material are important chronological indicators of the archaeological site in the system of the Chora of Chersonesos and in the whole Western Crimea.

Composite Form

In 2010, during the investigation of the site Asaviec 2 (Krivina peat bog, Beankovičy District, Viciebsk Region, Belarus) a unique set of tools in a case was revealed. It consists of an ornamented case made of the tubular bone of a large bird, an awl made of the lateral metapody of an elk, and a pointed bone item with an extension in the form of a wedge at one end. The method of experimental-traceological analysis was employed to determine the details of the manufacturing technology and the functional purpose of the find. According to the results of the study, a separate use of the tools was established - working with plant materials, which may indicate evidence of knitting or weaving products from organic fibers. Following experimental observations, some possible ways of working with these implements are considered. Thus, on the basis of the structural and contextual features of the artefacts, a variant of their use in a composite form, where the case served also as a handle is proposed. Bone awls or points are a widespread type of tools on sites from the Stone to the Bronze Age. However, the unique set found in situ allows us to expand our knowledge of the economy and productive activities of the past. Archaeological material, revealed an accompanying set of tools and a radiocarbon date from the underlying finding of conditional layer - 3810 50 BP (cal BC 2460-2064) (Le 10465), allow us to reconcile it with the antiquities of the Zhyzhyca-Kryvina stage of the Northern Belarusian Culture, middle of the 3rd-first half of the 2nd mill.

Houses and burials recorded in the settlements of Lepenski Vir I and II and burials previously ascribed to Lepenski Vir III are here discussed in view of the recent analyses of archaeological material and re-analyses of the field burial record from this site. Evidence of pottery in situ in houses of Lepenski Vir I, together with the evidence for important dietary change in the Lepenski Vir community in the course of the second half of the seventh millennium cal BC, reinforces the assumption, made by a number of scholars over several previous decades, of intensive contacts between early Neolithic groups and local hunter-gatherers. Burial practice throughout the seventh and sixth millennia cal BC at Lepenski Vir is thus reanalyzed in this new light. Apart from burials unrelated to architectural remains, five ‘types’ of burial deposition are noted in relation to houses of Lepenski Vir I–II, all but one having a distinct chronological and spatial patterning. The inhabitants' choice of mode of deposition of the deceased is always associated with a certain location in the settlement, sometimes used over several centuries. In the course of their history, these locations were often used for building a particular house or group of houses. The content of such houses is also discussed wherever it was possible. Duality in settlement organization could also be recognized in the burial practices related to settlement architecture. The attribution of the majority of burial remains to early Neolithic Lepenski Vir III is here also questioned in the light of new data and reinterpreted settlement sequences.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
