A Toca do Paraguaio, assim como outros doze sítios do Holoceno antigo, localizados no Parque Nacional Serra da Capivara, no sudeste do Piauí, apresentam conjuntos culturais que atestam uma multiplicidade de comportamentos arcaicos datados entre 12 e 8 mil anos BP. Assim, com o objetivo de identificar similaridades e diferenças nesses comportamentos, bem como promover uma correlação entre os sítios datados desse período, realizou-se um levantamento de dados na bibliografia disponível, na documentação antiga relativa aos sítios e em observações diretas nos conjuntos arqueológicos, o que levou ao estabelecimento de um quadro preliminar cronocultural do Holoceno antigo no sudeste do Piauí.ARCHAEOLOGICAL CONTEXT OF THE PARAGUAYTOUCH AND ANCIENT HOLOCENE OCCUPATIONS IN SOUTHEAST PIAUÍ, BRAZIL ABSTRACTThe Paraguaio rockshelter, as well as a set of twelve other sites dated to the Early Holocene and located in Serra da Capivara National Park in the southeast of Piauí, present cultural assemblages that attest to a multiplicity of archaic behaviors between 12 and 8 Kyr BP. Thus, in order to identify similarities and differences in these behavioral aspects, as well as to promote a correlation between the different sites on the southeastern border of the Parnaíba Basin, a data collection was done in the available bibliography, in the old documentation related to the sites and through direct observations in the archaeological records, which led to the establishment of an Early Holocene chronocultural preliminary framework for the southeast of PiauíKeywords: Early Holocene; Paraguaio rockshelter; Holocene Cultures; Lithic Industry; Rock-art; Funerary behavior

Abstract:
An investigation of crystal-size and microparticle variations has been carried out for the 1196 m ice core retrieved from Dome Summit South (DSS) near the summit of Law Dome, East Antarctica. Results show that for ice deposited during the Holocenr (depth <1103 m), microparticle concentrations are low. Variations of crystal size with in the Holocenc ice are due to growth with time at a temperature-dependent rate, and recrystallisation as a consequence of the ice flow. in the DSS ice core the highest microparticle concentration occurs close to the depth (1133 M) at which oxygen isotope ratios exhibit the greatest negative values, i.e. the Last Glaciol Maximum (LGM). Also at this depth, crystal size reduces sharply from a general crystal growth trend above to near minimum core values below. For ice originating during the LGM, the concentration of particles is an order of magnitude greater than the mean Holocene concentration. Laboratory annealing tests at -1 °C confirm the retarded crystal growth in the high-microparlicle-concent ration ice.

Abstract:
We are now accustomed to thinking of the Holocene as an epoch that we have left behind. But from what perspective do we close the Holocene and begin describing the Anthropocene? Academic disciplines have their own geology: epistemic or medial strata, sediments or condensations, which condition the apprehension and communication of fresh insight. The phrase ‘Holocene jurisprudence’ draws attention to a particular epistemic sediment: the figure of appropriation or ‘taking’, which is reactivated in many critical commentaries on the Anthropocene. And if, speaking figuratively, one were to identify an index fossil that compellingly expresses the epistemic traditions and potentialities that are sedimented into the Euro-American figure of appropriation, then Carl Schmitt's Nomos of the Earth would be a good candidate.

Abstract:
The timing and duration of the Holocene East Asian summer monsoon (EASM) maximum and the interpretation of Chinese stalagmite δ18O records have long been disputed. Notably, interpretations of Holocene EASM variations are frequently based on a single record or study area and are often contradictory. In this study, we conducted stable isotope analyses of four Holocene stalagmites from Chongqing, southwest China. The results reveal differences in the timing of the Holocene EASM maximum and to try to resolve the inconsistency we analyzed and statistically integrated a total of 16 Holocene stalagmite records from 14 caves in the EASM region. The resulting synthesized Holocene stalagmite δ18O (δ18Osyn) record is in agreement with other EASM records and confirms that stalagmite δ18O records are a valid indicator of EASM intensity, rather of local precipitation amount. The δ18Osyn record shows that the EASM intensified rapidly from the onset of the early Holocene; notably, however, there were distinct EASM oscillations in the early Holocene, consisting of three abrupt millennial-scale events. This indicates that, contrary to several previous interpretations, the early Holocene EASM was unstable. Subsequently, during 8–6 kyr BP, the EASM was relatively stable and strong, with the strongest monsoon occurring during 8–7 kyr BP. This evidence of a stable and strong mid-Holocene EASM in eastern China is in accord with the classical view of a mid-Holocene Optimum in China.

Abstract:
Sous le prisme de la pluridisciplinarité, la dichotomie entre anthropisation et environnement s’est réduite à mesure que de fortes interrelations dans les seuils d’évolution ont été démontrées. Les vallées fluviales constituent des supports d’observation privilégiés des relations hommes-milieux, et de nombreux fleuves ont fait l’objet de ce type d’étude ces dernières années. Le choix de la Garonne s’est imposé face au vide scientifique qui caractérise une grande partie du tracé au sein du Sud-Ouest de la France, en particulier la section moyenne. Ce travail se concentre donc sur l’étude des relations entre le peuplement et la basse plaine entre Toulouse et la confluence du Tarn depuis 10000 ans. La vallée atteint 25km de large à Toulouse et correspond à la première zone d’étalement des crues pyrénéenne, favorable à l’enregistrement des occupations passées et de la dynamique alluviale qui les a accompagnés. En l’absence de référentiel local, un cadre chronologique géomorphologique et archéologique a été mis en place pour l’Holocène à partir des travaux réalisés sur différents cours d’eau européens et continentaux. Ces deux volets ont ensuite été analysés distinctement sur la plaine de la Garonne à l’aide d’une méthodologie pluridisciplinaire. Les résultats montrent que l’occupation de la plaine alluviale est continue depuis le Néolithique, malgré une restitution biaisée par les travaux d’aménagement modernes et la taphonomie. Cette dernière est marquée par une forte mobilité du chenal de la Garonne et l’identification d’au moins deux épisodes d’incision au cours du 2nd l’Holocène et une nette diminution de l’alluvionnement depuis l’Antiquité
Through the prism of multidisciplinarity, the dichotomy between environment and human impacts is reduced as strong interrelationships in thresholds have been demonstrated. The valleys are favored supports of human-environnement relations, and many rivers have been the subject of this type of study in recent years. The Garonne’s choice result of a scientific blank in the most part of the channel in the South West of France, especially the middle section. Therefore this work focuses on the study of the relationship between human occupation and the low plain from Toulouse to the confluence of the Tarn since 10000 years. The valley is 25km wide in Toulouse and is the first Pyrenean flood spreading area, enabling the recording of past occupations and the alluvial dynamic associated. Without local repository, geomorphological and archaeological chronological framework was established for the Holocene, based on works completed in European and continental channels. These two component were analyzed separately on the plain of the Garonne river with a multidisciplinary approach. The results show that the floodplain’s occupation is continuous since the Neolithic, despite restitution biased by modern development works and taphonomy. This aspect is characterized by a high mobility channel f the Garonne and the identification of at least two episodes of incision in the 2nd Holocene and a net sedimentation decrease since Antiquity

Abstract:
L’évolution du climat Holocène a fait jusqu’ici l’objet de très peu d’études au niveau de la Bretagne. Celles-ci, s’inscrivant dans un contexte à la fois paléo-environnemental et archéologique, présentent souvent un caractère local et ponctuel qui permet difficilement de replacer les changements paléoenvironnementaux observés dans un contexte climatique plus global. Pourtant, la Bretagne, par sa particularité géographique et son exposition océanique, constitue un milieu de prédilection pour l’étude du climat puisqu’elle est fortement exposée, à l’actuel comme ce fut aussi le cas par le passé, aux aléas climatiques typiques de l’Atlantique Nord (régimes de tempêtes notamment) induits par les changements de configurations atmosphériques et océaniques. De plus, la région Bretagne présente une grande diversité de milieux littoraux, avec la présence de rias, d’estuaires, de marais salants, etc. Or, les environnements côtiers sous influence fluviale sont des puits sédimentaires soumis à de forts taux de sédimentation qui offrent l’opportunité d’enregistrer les changements environnementaux passés sur des milliers d’années. Les milieux d’arrière-plage (dunes, lagunes, tourbières), abondamment présents dans la région, constituent ainsi des domaines protégés de l’érosion marine et renferment des remplissages sédimentaires ayant potentiellement enregistré l’évolution séculaire et/ou millénaire du littoral breton, avec très certainement l’empreinte de certains évènements hydrodynamiques majeurs, mais aussi des traces de l’occupation humaine, dont certains auteurs ont montré le caractère précoce et croissant depuis le mésolithique. Ici, nous nous proposons de conduire des reconstitutions paléoenvironnementales et paléoclimatiques à partir de plusieurs séquences sédimentaires prélevées autour du littoral breton, afin de mieux comprendre la réalité des forçages naturels et/ou anthropiques sur les écosystèmes analysés. Pour mener à bien notre étude, nous avons développé une approche paléoécologique multidisciplinaire impliquant plusieurs disciplines complémentaires : sédimentologie et pétrographie, palynologie (pollen et dinokystes) et micropaléontologie(foraminifères benthiques et Chironomidae). Au final, l’analyse des séquences sédimentaires fournit une vision très précise et complète des fluctuations climatiques et environnementales qui ont caractérisé le Nord-Ouest de la France durant la seconde partie de l’Holocène, i.e. depuis les 7000 dernières années. Le recoupement des données entre les différents sites étudiés (1 site Nord Finistère et 2 sites Morbihan),montre l’hétérogénéité spatiale des données paléoécologiques qui caractérisent le secteur. Alors que les séquences prélevées sur les côtes sud bretonnes enregistrent un signal d’anthropisation dès le Néolithique moyen, celle-ci n’apparaît qu’à partir de l’Age du Bronze sur les côtes nord bretonnes, en accord avec les données archéologiques. De plus, nos données montrent que la néolithisation ne s’effectue pas de façon continue mais montre des phases de régression autour de la transition Néolithique final - Age du Bronze, en lien très certainement avec des détériorations climatiques. En effet, les périodes de froid signalées sur le nord de l’Europe durant l’Holocène et caractérisées par des récurrences de tempêtes dans la région Bretagne, semblent synchrones avec les chutes des marqueurs d’anthropisation mais aussi avec les retraits des populations de la côte vers l’intérieur des terres tels que décrits par les études archéologiques depuis le Néolithique final. Ces résultats suggèrent un impact direct du climat sur les dynamiques de population et d’occupation des territoires depuis le Néolithique en Bretagne

Sabendo-se que as condições hidrológicas de um sistema flu vial depende diretamente do clima regional, e que as mudanças climáticas do Holoceno atingiram várias regiões da Amazônia de diferentes formas, este trabalho visa r econstituir, através de estudos de sondagem lacustre, o cenário paleoambiental e as condi ções hidrológicas atuantes durante o Holoceno no lago Acarabixi, localizado na p lanície sedimentar do médio Rio Negro. A caracterização das unidades litológicas foi real izada através de medidas de densidade, teor em água, matéria orgânica, granulomet ria, e lâminas de material sedimentar bruto . A origem da matéria orgânica foi avaliada a partir da relação entre carbono e nitrogênio orgânicos e seus isótopos estáveis ( δ 13 C e δ 15 N), e de petrografia. A quantificação das frações minerais foi realizada atrav és de espectrometria de infravermelho, e a identificação através de análises de difração de raios X na fração argilosa. A cronologia foi realizada a partir de data ções radiocarbônicas ( 14 C) AMS. Os registros sedimentares de ambos os testemunhos analisados m ostraram a alternância entre ambientes de características deposicionais de maior e de menor energia hidrodinâmica. As diferenças apresentadas na sedimenta ção dos testemunhos estão relacionadas com a migração lateral do canal principal de um braço do Rio Negro que passa pelo Lago Acarabixi. Esses registros mostraram quatro fases de sedimentação: 9500-8100 14 C AP; 8100-7400 14 C AP; 7400-1600 14 C AP, e 1600 14 C AP–Presente. A ausência de registro sedimentar na terceira fase pelo test emunho ACA 02/03, está relacionada a fortes eventos de inundação, teriam remo vido o sedimento no testemunho ACA 02/03, que se localizava neste período m ais próximo do canal principal de corrente. A análise da matéria orgânica i ndicou origem pedogênica. Ela seria oriunda da lixiviação de solos podzólicos da bacia do Rio Negro, e transportada pelo Rio Negro e depositada junto com o sedimento no L ago Acarabixi. De modo geral, a planície de sedimentação estudada no Rio Negro demon strou ser um ambiente em que os centros de sedimentação variam ao longo do temp o. Estes centros de sedimentação estariam relacionados ao deslocamento latera l dos canais principais de correntes dos rios, além de seu preenchimento pelas ench entes. Podem ser reconhecidas duas fases neste preenchimento: uma fase de for te deposição com migração lateral dos canais até 8000 anos e uma fase de sedimentação mais lenta com características mais lacustres após 8000 anos AP
Knowing that the hydrologic conditions of a fluvial sy stem depends directly on the regional climate, and that the Holocene climatic chang es reached several areas of Amazonia in different ways, this work seeks to reconstitute , through studies of lacustrine survey, the paleoenvironment and the hydrologic condit ions active during Holoceno in the lake Acarabixi, located in the sedimentary plain of medium Rio Negro. The characterization of the litologics units was accomplished th rough density measures, % in water, organic matter, granulometry, and material she ets to silt up rude. The origin of the organic matter was evaluated starting from the relatio nship between carbon and organic nitrogen and δ 13 C and δ 15 N, and of petrografy. The quantification of the mine ral fractions was accomplished through infrared-espectrometry, and the identification through analyses of diffraction of rays X in the loamy fractio n. The chronology was accomplished starting from datings radiocarbônicas ( 14 C) AMS. The sedimentary registrations of both analyzed core showed the alternation among environmen ts from smaller and bigger hydrodynamic energy. The differences presented in the sedimentation of the core are related with the lateral migration of the main chann el of an arm of Rio Negro that goes by the Lago Acarabixi. Those registrations showed four sedimentation phases: 9500- 8100 14 C AP; 8100-7400 14 C AP; 7400-1600 14 C AP, and 1600 14 C AP-present. The absence of sedimentary registration in the third phase for the core ACA 02/03, is related to strong flood events, they would have removed the se diment in the core ACA 02/03, that was located closer of the main channel of current i n this period. The analysis of the organic matter indicated pedogenic origin. The organic matter would be originating from of the ‘ lixiviação’ of podzóls of Rio Negro basin, and transported by Rio Negro and deposited with the sediment in the Lago Acarabixi. In general, the sedimentation plain studied in Rio Negro demonstrated to be an environme nt in that the sedimentation centers vary along the time. These sedimentation cente rs would be related to the lateral displacement of the main channels of currents of the riv ers, besides it’s completion for the flooding. Two phases can be recognized in this comple tion: a phase of strong deposition with lateral migration of the channels to 8 000 years and a phase of slower sedimentation with more lacustrine characteristics after 8000 years AP.

Abstract:
Two reef systems off south Molokai, Hale O Lono and Hikauhi, show differences in modern ecosystem structure and Holocene accretion history that reflect the influence of wave-induced near-bed shear stresses on reef development in Hawaii. Both sites are exposed to similar impacts from southern, Kona, and trade wind swell, but differing wave impacts result from relative exposure to north swell. Analysis and dating of 10 cores from Hale O Lono reveal a back stepping reef ranging from ~8,100 cal yr BP (offshore) to ~4,800 cal yr BP (nearshore). A depauperate community of modern coral diminishes shoreward and seaward of~15 m depth due to wave energy, disrupted recruitment activities and physical abrasion. Evidence suggests a change from conditions conducive to accretion during the early Holocene to conditions detrimental to accretion in the late Holocene. Reef structure at Hikauhi, reconstructed from 14 cores, reveals a thick, rapidly accreting and young (maximum age ~900 cal yr BP) prograding reef. Modem live coral cover on this reef increases seaward with distance from the reef crest but terminates at a depth of ~20m where the reef ends in a large sand field. The primary limitation on vertical reef growth is accommodation space under wave base, not recruitment activities or energy conditions. This study suggests modem reef growth on the southwest comer of Molokai is controlled by wave-induced near-bed shear stress related to refracted North Pacific swell. Holocene accretion patterns here also reflect the influence of wave-induced near-bed shear stress from north swell. Other factors controlling Holocene reef accretion are relative sea-level and wave sheltering by Laau Point. Habitat suitable for reef accretion on the southwest shore of Molokai has shrunk throughout the Holocene.

Ouellette, Gilman Reno. "Late Holocene Paleoenvironmental Reconstruction in Barbados." TopSCHOLAR®, 2013. http://digitalcommons.wku.edu/theses/1285.

Full text
Abstract:
Barbados is the easternmost island in the Caribbean region, and is uniquely situated between the Atlantic Ocean and Caribbean Sea. Being an isolated island with a karstified aquifer providing the majority of the nation’s water resources, Barbados has found itself in water scarce situations in recent years. In order to better understand natural shifts in groundwater recharge (which is determined by shifts in precipitation), longer records of precipitation are needed than are available from modern measurements. This study presents a paleoclimate reconstruction for the late Holocene on Barbados using stable and radiogenic isotope ratios in speleothem lamina as proxies. In addition, it introduces the use of novel mineralogical analyses using Raman spectroscopy and large chamber-scanning electron microscopy to supplement the oxygen isotope record. For the past 1,500 years, the speleothem record indicates average δ18O values near -4.1 0/00, maximum δ18O values around -3.2 0/00 that coincide with the Little Ice Age climate event, while minimum δ18O values around -5.3 0/00 occur during the Medieval Climate Anomaly. Raman spectral analysis shows a recent period of increased Mg substitution, which potentially represents anthropogenic changes to the island’s epikarst aquifer caused by European settlement and sugar cane cultivation on Barbados. Electron imaging revealed chemically distinct layers of detritus within the stalagmite sample, facilitating precise sampling for U-series dating while also providing some information on the nature of weathering on the island. Additionally, time series analysis of the isotope record indicates multidecadal and multicentennial periodicities that conform well to that of the Atlantic Multidecadal Oscillation exerting influence on rainfall variability at the decadal scale, and the Intertropical Convergance Zone modulating rainfall at the multicentennial scale. Collectively, these data provide a climate reconstruction for the island of Barbados that is useful for better understanding change in cyclic precipitation patterns, as well as non-destructive methods for speleothem analysis that complement the isotopic study, while allowing sample preservation.

Abstract:
The Mediterranean has long been recognised as an area that is particularly sensitive to climate change. It is also an area that has been impacted by human activity for millennia. Disentangling climatic and anthropogenic influences on the history of vegetation change in the Mediterranean remains an important challenge. As a contribution to this ongoing debate, this thesis explores the late Holocene environment of part of the coast in Central Italy using a multiproxy approach to investigate the archives of change preserved in dune slack deposits. Distinguishing between natural and anthropogenic signals presents a real challenge in most environmental reconstruction work; however, due to the extensive archaeological research carried out at Castelporziano, it is possible to examine human-environmental interactions in some detail. In order to understand these interactions part of the thesis examines how management has affected recent environmental changes and the current vegetation and whether there is a legacy of Roman landuse at the Castelporziano estate. The key findings of the thesis showed that dune slacks are suitable for palaeoenvironmental reconstruction with proxies such as plant macrofossils, ostracods, molluscs and bryozoans statoblasts. However, the pH and seasonality of the slacks meant proxies such as pollen were badly preserved or absent, and diatoms did not preserve due to the high levels of carbonate on site. Overall the results show the impact of the Romans on site in terms of localised eutrophication and increased fires, but with abandonment, came the formation of wet woodlands.

Abstract:
The landscape of the Netherlands has been changing constantly since the end of the last ice age, some 11,700 years ago. Where we walk today was once a polar desert, a river delta or a shallow sea. The end of the last ice age marked the beginning of a new geological period - the Holocene, the relatively warm geological epoch in which we are still living today. The Atlas of the Holocene Netherlands contains special maps, supplemented by archaeological and historical information. These maps show the geographical situation for thirteen different points in time since the last ice age, based on tens of thousands of drill samples and the latest geological, soil and archaeological research. This magnificent atlas also paints a surprising picture of the position we humans have occupied in the landscape. It addresses such questions as: How did we take advantage of the opportunities offered by the landscape? And how did we mould the landscape to suit our own purposes? The Atlas of the Holocene Netherlands will change once and for all the way you look at the Dutch landscape.

Abstract:
На основе палинологических данных, восстановлена история развития природной среды аккумулятивной равнины в кутовой части Уссурийского залива за последние 5350 кал. л. Определены особенности структуры растительного покрова в завершающую фазу оптимума голоцена, а также при разнонаправленных климатических флуктуациях позднего голоцена. В завершающую фазу оптимума голоцена широколиственные растения в горном обрамлении были распространены более широко, чем в настоящее время. На аккумулятивной равнине преобладали мелколиственные растительные сообщества с доминированием березы обыкновенной, гибридных берез и ольхи. Похолодание, начавшееся в конце среднего и продолжившееся в начале позднего голоцена, привело к сокращению в растительности широколиственных растений и более широкому распространению мелколиственных. В конце позднего голоцена в кутовой части Уссурийского залива сложились природные условия, обусловившие формирование современной структуры растительности. Based on the palynological data, the history of vegetation on the accumulative plain in the inner part of the Ussuri Bay was reconstructed. Features of the structure of the vegetation cover during the final phase of the Holocene optimum and at multidirectional climatic fluctuations in the Late Holocene were identified. Broad-leaf plants in the final phase of the Holocene were more widely-spread on the surrounding mountain than at present. On the accumulative plains grassy meadows with small-leaf plant communities dominated. Deterioration of natural conditions during the transition to the Late Holocene caused a decrease in vegetation of broad- leaved plants and in an increase in the role of small-plants. At the end of the Late Holocene natural conditions developed in the inner part of the Ussuri Bay, that conditioned the formation of the modern structure of vegetation.
