This thesis deals with a medieval material from Rounala in Karesuando parish, Norrbotten county, Lapland. The aim is to reconstruct the diet and mobility patterns. It is through carbon, nitrogen and sulphur stable isotopes and radiocarbon that both pastoralist traits and whether which part Christianity played in the burial traditions of these human remains is being studied. Another aim is to discuss the repatriation issue as these remains are subjected to. The results mainly show that all individuals had a mixed diet and no pastoral way of living has been established. Furthermore, individual 3 is suffering from pathological changes. With radiocarbon dates ranging from 1300 to 1720 AD, two groups can be distinguished as to whom had been buried before and after the construction of the church. And repatriation is being discussed as an issue to who have ownership over ancient remains.

Substantiation and formulation of schematization principles of the Quaternary multi-aquifer system for conceptualization of groundwater flow model based on the complex of lithologic, hydrogeochemistry, isotopic and hydraulic data have been developed by this dissertation. Performing data analysis of hydraulically tested aquifers, the hydrogeological parameters which have been used in simulation and their reliability have been adjusted during model calibration based on hydrogeological–hydrological water balance methods with coupled groundwater isotopic-chemistry investigations. Transformation of groundwater isotope-hydrogeochemical composition in the direction from the recharge area toward the discharge places have been estimated on a selected experimental hydrogeological cross–section. According to tritium and simulation modelling data, groundwater flow scheme and average velocity comparison have been made from the highland to lowland. The pre–development groundwater flow and prognostic assessment of groundwater exploitation resources of Quaternary aquifer system with extraction impact on the geoenvironment have been evaluated.

High Arctic permafrosted soils represent a massive sink in the global carbon cycle, accounting for twice as much carbon as what is currently stored as carbon dioxide in the atmosphere. However, with current warming trends this sink is in danger of thawing and potentially releasing large amounts of carbon as both carbon dioxide and methane into the atmosphere. It is difficult to make predictions about the future of this sink without knowing how it has reacted to past temperature and climate changes. This dissertation summarizes the results of the first study to look at long term, fine scale organic carbon delivery by the high-Arctic Colville River into Simpson’s Lagoon in the near-shore Beaufort Sea. Modern delivery of organic carbon to the Lagoon was determined to come from a variety of sources through the use of a three end-member mixing model and sediment biomarker concentrations. These sources include the Colville River in the western area of the Lagoon near the river mouth, marine sources in areas of the Lagoon without protective barrier islands, and coastal erosional sources and the Mackenzie River in the eastern area of the Lagoon. Downcore organic carbon delivery was measured on two cores in the Lagoon, one taken near the mouth of the Colville River (spans about 1800 years of history) and one taken on the eastern end of the Lagoon (spans about 600 years of history). Bulk organic parameters and biomarkers were measured in both cores and analyzed with Principle Component Analysis to determine long-term trends in organic carbon delivery. It was shown that at various times in the past, highly degraded organic carbon inputs of what is likely soil and peat carbon were delivered to the Lagoon. At other times, inputs of fresher, non-degraded, terrestrially-derived organic carbon inputs of what are likely higher amounts of plant and vegetative material was delivered to the Lagoon. Inputs of degraded soil carbon were also shown to correspond to higher temperatures on the North Slope of Alaska, likely indicating that warmer temperatures lead to a thawing of permafrost and in turn organic carbon mobilization to the coastal Beaufort Sea.

Chavín de Huántar is one of the key sites of the Formative Period in the Central Andes, with many decades of investigations by dozens of investigators, but ironically its chronology is still poorly defined and contested. This article reviews the historical evidence for Chavín chronology, emphasizing an examination of calibrated radiocarbon dates, and summarily reviewing related radiocarbon evidence from approximately contemporary sites. The more voluminous C14 evidence from recent work at Chavín is then examined, particularly focused on dates from known ceramic and architectural contexts. A large number of determinations concur, both in and outside of Chavín, in dating stamped polished blackware "janabarroide" ceramics in the range of 800-500 BC in calibrated age. Earlier and later occupations at Chavín are documented, helping confirm this time range for "Early Horizon" materials. Chavín, unlike some other important Formative sites, loses its temple function by around 500 BC calibrated, although major construction seems to have greatly decreased well before that time. / Chavín de Huántar es uno de los sitios fundamentales para entender el Periodo Formativo en los Andes centrales. Irónicamente, a pesar de muchas décadas de investigaciones realizadas por docenas de investigadores, su cronología es todavía debatida e insegura. Este artículo presenta una reseña de la evidencia histórica para la cronología de Chavín, enfatizando la contribución de los fechados radiocarbónicos calibrados y, de manera breve, revisando los que están temporalmente relacionados con otros sitios formativos. Se analizan, también, los numerosos fechados de carbono-14 asociados a cerámica y contextos arquitectónicos conocidos en Chavín derivados de estudios recientes. De hecho, muchos fechados de Chavín y sitios relacionados concuerdan en ubicar a la cerámica negra pulida estampada, denominada janabarroide, alrededor de 800-500 a.C. (calib.). La presencia de ocupaciones anteriores y posteriores, documentadas con fechados, ayudan a confirmar este rango temporal para materiales reconocidos del "Horizonte Temprano". En contraste con algunos otros importantes sitios formativos, Chavín deja de funcionar como templo hacia 500 a.C. (calib.), aunque los esfuerzos destinados a las construcciones principales ya estaban disminuyendo, de manera notable, antes de esta época.

Tiwanaku in Moquegua: Regional Interactions and CollapseThe synthesis of data from excavations and systematic survey of the Osmore drainage promotes a new vision of the relationships between Wari, Tiwanaku, and indigenous people of the region during the Middle Horizon and the beginning of the Late Intermediate Period. A series of facts are effectively established that must be considered in future interpretations. Among others, we note the apparent contemporaneity of Tiwanaku and Wari settlements in the middle and upper sections of the Osmore drainage, generally isolated in their own geographic zones. There are no signs of military conflict or fear of it during perhaps centuries of contact, even though both groups considered the site of Cerro Baúl to be a huaca that only the Wari controlled. Nor was there exchange of goods, suggesting social as well as spatial isolation. We describe the contemporaneity of two Tiwanaku traditions, marked by the Omo and Chen Chen ceramic styles, which were previously considered sequential phases. Finally, we confirm that at the end of the Middle Horizon. Wari abandoned the region, leaving people of the Tiwanaku tradition to divide into local groups and flee to distant, defensible sites at the beginning of the troubled times of the Late Intermediate Period. / La síntesis de datos de excavaciones y reconocimientos sistemáticos de la cuenca del río Osmore permite una visión nueva de las relaciones entre los wari, tiwanaku y poblaciones indígenas de la región durante el Horizonte Medio y el comienzo del Periodo Intermedio Tardío. Una serie de hechos están efectivamente establecidos, los cuales tendrán que ser considerados en futuras interpretaciones. Entre otros, se nota la aparente contemporaneidad de asentamientos tiwanaku y wari en las partes medias y altas de la cuenca del Osmore, pero mayormente aisladas en zonas geográficas separadas. No hay indicios de conflicto bélico ni temor de tal durante, posiblemente, siglos de contacto, a pesar de que ambos grupos vieron al mismo sitio Cerro Baúl como una huaca, la que únicamente los wari controlaron. Tampoco había intercambio de bienes, sugiriendo un aislamiento social al igual que espacial. Se describe la contemporaneidad de dos tradiciones tiwanaku marcadas por los estilos ceramográficos Omo y Chen Chen, que antes se consideraban fases secuenciales. Finalmente, se confirma que, al fin del Horizonte Medio, la gente wari abandonó la región, mientras que los de la tradición Tiwanaku se dispersaron en grupos menores desplazándose a sitios alejados y defendibles al comienzo de los tiempos conflictivos del Periodo Intermedio Tardío.

Sonay: A Wari Orthogonal Cellular Center in the Camana Valley, PerúThe site of Sonay is located in the Camana Valley of southern Peru. Investigations in the 1990s revealed the presence of a Wari center at the site, identified by its characteristic orthogonal architecture. Testing of the site recovered two radiocarbon samples that provided tenth century dates for the construction of the center. Few artifactual remains were recovered, suggesting a brief occupation of the site. Descriptions of the research are presented, together with an interpretation of the significance of the results. The late dates for the center support the emerging view that Wari political power lasted considerably longer that early researchers had indicated. / EI sitio de Sonay está ubicado en el valle de Camaná en el centro sur del Perú. Las investigaciones durante los años noventa dieron a conocer la presencia de un centro wari, identificado por la característica arquitectura ortogonal. Las excavaciones de prueba en el sitio produjeron dos muestras radiocarbónicas que arrojaron fechas hacia el décimo siglo d.C. para su construcción. Se encontraron pocos artefactos, lo que sugiere una ocupación breve. Se presenta una descripción de las investigaciones tanto como una interpretación de la importancia de los resultados. Las fechas tardías del centro apoyan la nueva visión de que el poder político wari duró mucho más tiempo de lo que anteriores investigadores indicaban.
