Документ Black Sea and Caspian Basins in Late Pleistocene: sea-level changes, climate and early human settlement(S.n, 2008) Dolukhanov, P. M.; Chepalyga, A. L.; Lavrentiev, N. V.; Kadurin, Serhii V.; Larchenkov, Yevhenii P.; Shkatova, V. KThe climate of northern Eurasia during the Middle Wiirm/Valdai 'megainterstadial' (OIS 3), which lasted from c. 58 to 23 ka, was cool and unstable, with at least five milder oscillations (including the 'Bryansk interstadial'). The estimated summer and winter temperatures in Eastern Europe were lower than today by 4-6°C and 4-10°C, and the annual precipitation, as low as 150-250 mm (Frenzel et al.,1992).Документ C14 dating and facies control of paleo-shorelines location on NW Black Sea shelf in Holocene(Astroprint, 2011) Kadurin, Serhii V.; Larchenkov, Yevhenii P.The northwestern Black Sea shelf was an alluvial plain that was flooded in the course of the Late Neoeuxinian and Chernomorian transgression (Larchenov and Kadurin, 2011). The latter started ca. 9.4 ka BP (all radiocarbon dates in this paper are in non-calibrated years BP), and occurred in an oscillatory or transgressive-regressive manner. Each transgressive-regressive stage formed its own paleocoastline, which is well expressed in the shelf relief (Larchenkov and Kadurin, 2011). Because the number of samples dated by l4C from paleocoastlines is relatively small, interpolation and extrapolation methods along with facies analysis of bottom sediments are required.Документ Comparison of the sea level fluctuations in the Atlantic Ocean, Mediterranean and Black Seas for the last 100 years(Astroprint, 2011) Yanko-Hombach, Valentyna V.; Lykhodedova, Olha H.; Larchenkov, Yevhenii P.; Янко-Хомбах, Валентина Венедиктовна; Янко-Хомбах, Валентина Венедиктівна; Лиходедова, Ольга Георгиевна; Лиходідова, Ольга Георгіївна; Ларченков, Євген Павлович; Ларченков, Евгений ПавловичThere is no consensus about the mode by which sea level changed in the Black Sea during the Holocene(Yanko-Hombach, 2007). Some scientists (e.g., Balabanov, 2007; Yanko-Hombach,2007)suggest that Black Sea level changes occurred in an oscillatory manner,while others (e.g., Pirazzoli, 1991; Bruckner et al., 2010) challenge this.In their opinion,the sea-level changes in the Black Sea cannot be different from those that occurred in the World Ocean in general, and the Mediterranean Sea in particular.This paper focuses on the comparison between sea-level fluctuations deduced from instrumental observations in the Atlantic Ocean, Mediterranean,and Black Sea during the last 100 years.The main goal is to show how(but not why!)the Black Sea level has behaved most recently.We understand perfectly that geological time is not comparable with that of the period of instrumental observations. However,it is probable that the behavior of the Black Sea level in recent time and in the geological past could show similar patterns but on a different scale.Документ Depositional environments of the Northwestern Black Sea inner and middle shelf during the Late Pleistocene and Holocene(S.n., 2008) Larchenkov, Yevhenii P.; Kadurin, Serhii V.; Kakaranza, S. D.The Black Sea level rise of up to 90 m during the past 25 ky led to a progressive shift from terrestrial and nearshore depositional environments to marine shelf settings. This work is aimed at reconstructing the depositional environments on the northwestern Black Sea shelf during the Late Pleistocene and Holocene.Документ DEPOSITIONAL ENVIRONMENTS ON THE NORTHWESTERN BLACK SEA OUTER SHELF AND CONTINENTAL SLOPE DURING LATE PLEISTOCENE AND HOLOCENE(Rosselkhozakademiya Printing House, 2007) Larchenkov, Yevhenii P.; Kakaranza, S. D.Neoeuxinian sea-lake appeared 25-30 ky ago and was the last isolated basin in the Black Sea region. It was characterized by very narrow shelf connected with the continental slope and rise. Due to subsequent the sea-level rise, a wide shelf was formed along the NW Black Sea where the basin coastline has been traced by thick sandy nearshore deposits at the depths of 87-88 m below pre-sent sea level. The changes affected the sedimentation in the shelf-continental slope transitional area. This work is aimed at reconstructing depositional environments of the region during Late Pleistocene and Holocene.Документ Distribution of Holocene sediment thickness on the northwestern Black Sea shelf(S.n, 2008) Kadurin, Serhii V.; Eriomina, L. Ju.; Larchenkov, Yevhenii P.Reconstruction of the geological history and neotectonic activity of the northwestern Black Sea shelf requires an analysis of the thickness of the Holocene deposits. The study region includes the inner shelf from the Sarat rise to the central part of the Tendra rise, and it encompasses the middle shelf and substantial areas of the outer shelf to the south. Using vibracore data from "Prichernomorgeologia," we obtained more than 400 measurements of deposit thickness, as well as 28,100 interpolated values. The main goal of the research is assessment of the spatial distribution of deposit thickness on the northwestern Black Sea shelf through standard statistical analyses and GIS- aided mapping. The objectives are: evaluation of statistical parameters of sediment thickness distribution, and mapping of areas with anomalous Holocene deposit thicknesses.Документ DYNAMICS OF THE COASTAL NORTH PONTIC AREA IN LATE PLEISTOCENE AND HOLOCENE AND EARLY HUMAN DISPERSAL(Rosselkhozakademiya Printing House, 2007) Dolukhanov, P. M.; Kadurin, Serhii V.; Larchenkov, Yevhenii P.The initial expansion of anatomically modern humans (АМН) and the spread of Upper Palaeolithic (UP) technologies in the Northern Black Sea area occurred during 40 - 25 k.y. BP. This process became further intensified during the LGM, 25-15 ka BP. Both these periods coincided with the 'transitional' and 'cold' phases of the Dansgaard-Oeschger (DO) cycles, and included at least three 'Henirich episodes' H4 (38 ka BP), H3 (31 ka BP) and H2 (24 ka BP). During all that time the Black Sea depression was taken up by the Neoeuxine fresh-water mega-lake with the Caspian type molluscan fauna. At 30-25 ka BP its level was 87-90 m below NN. The exposed shelf jointly with the North-Pontic Lowland south of the Dnepr formed a huge erosion-depositional plain, which included the Pra-Prut, Pra-Dniestr and Pra-Bug alluvial plain. Further to the south, lie the terraced alluvial plain, formed by the lower stretches of the Dnepr, Dniester and Danube with their extended marshy flood-plains, and separated by local watersheds. An actively developing low-lying deltaic accretion plain was located closer to the shelf outer rim. It consisted of numerous river branches with sand bars separating marshes and mires (Larchenkov, Kadurin 2005). UP sites of that age (such as Sagaidak 1, Anetovka 2, Amvrosievka, and Muralovka) are usually found inside deep valleys of the small river, which provided for natural protection in harsh environment (Stanko et al. 1989). This type of landscape were excessively rich in biomass, guaranteeing stable and diversified food resources. The common occurrence of similar landscapes makes one suggest, that similar settlements occurred in the actually submerged part of the shelf.Документ Heavy-mineral concentrations as proxies of high-energy events along sandy coasts(Astroprint, 2006) Buynevich, I. V.; Larchenkov, Yevhenii P.; Oakley, B. A.Sediment-rich coastal sequences have the potential of preserving long-term records of regional-scale erosional events. Among the most diagnostic features of erosion are steep berm and dune scarps, regional unconformities (discontinuities), layers of coarse sediment or shell hash, as well as extensive accumulations of heavy minerals (magnetite, ilmenite, garnet, zircon, hornblende, etc.). These heavy mineral concentrations (HMCs) are found in many parts of the world and occur in thin layers or thick placer deposits (Fig. 1A). Their formation is due primarily to selective density sorting during the waning stages of storms (Komar and Wang, 1984; Peterson et al., 1986; Kurian et al., 2001). The HMCs can therefore be used as proxies for high-energy events along sandy coastal regions, and have been attributed to storm or tsunami-induced erosion in a number of studies (Smith and Jackson, 1990; Nichol, 2002; Buynevich et al., 2004; Dougherty et al., 2004). Substantial contrast in electromagnetic properties between sands enriched in ferromagnesian heavy minerals and quartz-rich background sediments is responsible for the sharp nature of subsurface reflections (Meyers et al., 1996; Buynevich et al., 2004) making HMCs some of the most prominent horizons in ground-penetrating radar (GPR) profiles (Fig. 1B). By combining high-resolution geophysics for mapping subsurface erosional indicators with radiocarbon or optical dating of individual erosional horizons, it is possible to reconstruct the long-term history of coastal hazards in various parts of the world.Документ Holocene marine transgression in the Black Sea: New evidence from the northwestern Black Sea shelf(Elsevier, 2014) Yanko-Hombach, Valentyna V.; Mudie, Petra J.; Kadurin, Serhii V.; Larchenkov, Yevhenii P.; Янко-Хомбах, Валентина Венедиктовна; Янко-Хомбах, Валентина Венедиктівна; Муди, Петра Дж.; Муді, Петра Дж.; Кадурін, Сергій Володимирович; Кадурин, Сергей Владимирович; Ларченков, Євген Павлович; Ларченков, Евгений ПавловичFor two decades, the timing and rate of Holocene marine transgression and the level of the Black Sea prior to the transgression has been the focus of many geological, palaeoecological and archaeological studies. The potential importance of confirming or rejecting the catastrophic flood hypothesis by refining the chronology of the marine transgression and determining the water level of the early Holocene Black Sea (Neoeuxinian) lake is the aim of many ongoing Black Sea palaeoecological studies. In this report we review previous studies and present new data on the early Holocene marine transgression obtained from multidisciplinary studies of several cores from different parts of the Black Sea. Core 342 from the edge of the Dniester paleovalley on NW shelf is particularly important because it provides wood and leaf material from several peat and muddy peat beds, each up to 10 cm thick, interlayered in a coastal succession with mud, clay, and shell coquina. AMS ages for wood fragments and sedge leaves in the peat layers provide critical new data for calibrating and “re-tuning” of previously published shell and bulk detrital peat ages. Our multi-disciplinary study of geological material recovered from different shelf areas of the Black Sea refines the chronology of the marine transgression and clarifies conflicting interpretations of the water level and salinity of the Neoeuxinian lake prior to the initial Mediterranean inflow (IMI) and transgression of Mediterranean water in the Holocene, We find that: (1) The level of the Late Neoeuxinan lake prior to the early Holocene Mediterranean transgression stood around -40 m bsl but not -100 m or more as suggested by advocates of catastrophic/rapid/prominent flooding of the Black Sea by Mediterranean water. (2) At all times, the Neoeuxinan lake was brackish with salinity not less that 7 psu. (3) By 8.9 ka BP, the Black Sea shelf was already submerged by the Mediterranean transgression. An increase in salinity took place over 3600 years, with rate of the marine water incursion being estimated in the order of 0.05 cme1.7 cm a(-1). (4) The combined data set of sedimentological characteristics and microfossil data establish that the Holocene marine transgression was of a gradual, progressive nature in the early Holocene.Документ Lithology, biochemistry, and micropaleontology of mud volcanoes and high-intensity cold seeps on the bottom of the Black Sea and Sea of Azov(S.n., 2008) Yanko-Hombach, Valentyna V.; Konikov, Yevhenii G.; Kravchuk, Anna O.; Kadurin, Serhii V.; Kravtsov, V.; Larchenkov, Yevhenii P.; Smyntyna, Olena V.; Янко-Хомбах, Валентина Венедиктовна; Янко-Хомбах, Валентина Венедиктівна; Коніков, Євген Георгійович; Коников, Евгений Георгиевич; Кравчук, Ганна Олегівна; Кравчук, Анна Олеговна; Кадурін, Сергій Володимирович; Кадурин, Сергей Владимирович; Кравцов, В.; Ларченков, Євген Павлович; Ларченков, Евгений Павлович; Сминтина, Олена Валентинівна; Смынтына, Елена ВалентиновнаThe Odessa National I.I. Mechnikov University Team focused on the geological, gcochemical,mineralogical,and micropaleontological study of mud volcanoes and high intensity gas seeps in the northern Black Sea in order to assess their origin and possible influence on ecosystems, thus, contributing to HERMES WP1 and WP3.As a first step, compiling and integration of existing data (published and archival) obtained by previous projects was conducted by a variety of organizations.This enabled us to create a GIS-aided map of previous research,at least in the northwestern part of the Black SeaДокумент New evidence from the Northwestern Shelf for holocene marine transgression of Northwestern Black Sea(LTD "Sachino", 2013) Yanko-Hombach, Valentyna V.; Mudie, Petra J.; Kadurin, Serhii V.; Larchenkov, Yevhenii P.; Янко-Хомбах, Валентина Венедиктовна; Янко-Хомбах, Валентина Венедиктівна; Муди, Петра Дж.; Муді, Петра Дж.; Кадурин, Сергей Владимирович; Кадурін, Сергій Володимирович; Ларченков, Евгений Павлович; Ларченков, Євген ПавловичFor two decades, the timing and rate of Holocene marine transgression and the level of the Black Sea prior to the transgression has been the focus of many geological, paleoecological, and archaeological studies. The potential importance of confirming or rejecting the catastrophic flood hypothesis by refining the chronology of the marine transgression and determining the water level of the early Ilolocene Black Sea (Neoeuxinian) lake is the aim of many ongoing Black Sea paleoecological studies. In a new study, we undertook to review a vast array of previous geological and paleoecological studies, including the original sites of Ryan et al. (1997) which were used to hypothesize a catastrophic Holocene flood, and we have obtained new data on the onset and rate of the early Holocene marine transgression using multidisciplinary studies of 19 cores from different parts of the Black Sea.Документ NORTH-WESTERN BLACK SEA SHELF BOTTOM LANDSCAPES(Rosselkhozakademiya Printing House, 2007) Larchenkov, Yevhenii P.; Kadurin, Serhii V.Seafloor landscapes of the northwestern Black Sea shelf have been formed on submerged Pre-Holocene North Pontic alluvial plain paleo-relief due to sedimentation and development of benthic biocenoses. This paper describes various aspects of shelf morphology.Документ Paleogeography of the northwestern Black Sea shelf during the last 12 ka(S.n., 2010) Larchenkov, Yevhenii P.; Kadurin, Serhii V.At present, the problem of Black Sea formation during the last 25-30 ka remains the focus of interest for geologists and geographers who have investigated this problem over many decades, and also for archaeologists and experts in social-economic and political studies. Forecasts of possible shoreline changes during the next 50-100 years are important and ongoing tasks, and successful solution of this problem is essential for preparation of long-lasting development strategies for sea transport and recreational zones, construction in the shore belt, as well as other important plans.Документ Reconstruction of north-western Black Sea coastline positions for the past 25 ky(Astroprint, 2006) Larchenkov, Yevhenii P.; Kadurin, Serhii V.Recent relief and shoreline of NW Black Sea shelf have been formed through interaction of various processes: eustatic sea-level change, sedimentation/erosion, and the subsequent vertical movements during last 25 ky (Fedorov, 1988; Larchenkov, Kadurin, 2005). This work is aimed at reconstructing the seafloor relief and the locations of past shorelines along the NW Black Sea (Ukraine).Документ Was the Black Sea catastrophically flooded in the Early Holocene - a new perspective from the large scale geological survey of the northwestern shelf(S.n., 2010) Yanko-Hombach, Valentyna V.; Kadurin, Serhii V.; Larchenkov, Yevhenii P.; Lykhodedova, Olha H.; Kakaranza, S. D.; Янко-Хомбах, Валентина Венедиктовна; Янко-Хомбах, Валентина Венедиктівна; Караканза, С. Д.; Кадурін, Сергій Володимирович; Кадурин, Сергей Владимирович; Ларченков, Евгений Павлович; Ларченков, Євген Павлович; Лиходедова, Ольга Георгиевна; Лиходідова, Ольга ГеоргіївнаWas the Black Sea catastrophically flooded in the Early Holocene or not? This question has been hotly debated since Ryan et al. (1997) first proposed their hypothesis of a catastrophic inflow of Mediterranean seawater into a Black Sea freshwater lake (locally called the Neoeuxinian Lake) at 7.2 ka BP. This hypothesis claimed that a massive inundation of the Black Sea basin and ensuing large-scale environmental changes drastically impacted early societies in coastal areas, forming the basis for Great Flood legends and other folklore, and accelerating the spread of agriculture into Europe. This scenario (called here the "Flood Hypothesis") was widely publicized and discussed in the general media. In response to criticism, and based on reevaluation of old data as well as new data, the authors of the Flood Hypothesis pushed the date of their inundation back 1200 years to 8.4 ka BP (Ryan et al. 2003). Instead of a single inundation, two lowstands (-120 m at 13.4—11.0 ka BP; and -95 m at 10.0-8.4 ka BP) and two catastrophic floods (sea-level rise from -120 to -30 m at 11.0-10.0 ka BP; and from -95 to -30 m at 8.4 ka BP) were proposed. The second of these two major transgressions was labeled the Great Flood. The initial Flood Hypothesis was based on evidence from seven short (about 1.25 m each), low- resolution sediment cores and 350 km of seismic profiles collected within a fairly restricted area of the Black Sea's NW shelf at water depths between 49 and 140 m during a single mission in 1993.Документ Изменение уровня в Атлантическом океане, Средиземном и Черном морях в столетнем цикле(2013) Янко-Хомбах, Валентина Венедиктовна; Yanko-Hombach, Valentyna V.; Янко-Хомбах, Валентина Венедиктівна; Лиходідова, Ольга Георгіївна; Ларченков, Евгений Павлович; Ларченков, Євген Павлович; Larchenkov, Evgen P.; Larchenkov, Yevhenii P.; Lykhodedova, Olha H.; Лиходедова, Ольга ГеоргиевнаЦель работы состояла в установлении сходства и различия колебаний уровня в Атлантике, Черном и Средиземном морях. Очевидно, что сравниваемые морские бассейны существенно различаются как по своим параметрам (площадь, объем, глубина), так и по факторам, формирующих их водный режим, в то же время, они находятся под действием общих факторов глобального характера, влияющих на изменение уровня.Документ Колебания уровня Черного моря и адаптационная стратегия древнего человека за последние 30 тысяч лет(2011) Янко-Хомбах, Валентина Венедиктовна; Смынтына, Елена Валентиновна; Кадурин, Сергей Владимирович; Ларченков, Евгений Павлович; Мотненко, И. В.; Какаранза, С. В.; Киосак, Дмитрий Владимирович; Yanko-Hombach, Valentyna V.; Янко-Хомбах, Валентина Венедиктівна; Сминтина, Олена Валентинівна; Smyntyna, Olena V.; Кадурін, Сергій Володимирович; Kadurin, Serhii V.; Ларченков, Євген Павлович; Larchenkov, Yevhenii P.; Мотненко, Ірена; Motnenko, Irena; Kakaranza, S. V.; Кіосак, Дмитро Володимирович; Kiosak, Dmytro V.В статье рассматривается эволюция и взаимосвязь природной среды и древнего человека в северо западном Причерноморье в позднем плейстоцене и голоцене. Установлено, что в течение последних 30 тыс. лет уровень Черного моря колебался в осцилляционном или возвратно-поступательном режиме. Быстрый подъем уровня в позднем плейстоцене повысил уровень ранненовоэвксинского озера от –100 м до –20 м к началу голоцена, возможно, за счет сброса каспийских вод по Манычу. В максимум последнего оледенения (27–17 т.л.н.), когда уровень новоэвксинского солоноватоводного озера был на 100 м ниже современного, стоянки позднепалеолитического человека располагались в пределах глубоких долин небольших речек, которые были затоплены в процессе поздненовоэвксинской трансгрессии (17–10 т.л.н.), но хорошо прослеживаются геоморфологически на нынешнем шельфе Черного моря. Это обстоятельство может быть использовано при поиске затопленных позднепалеолитических поселений на шельфе, где, скорее всего, находятся ныне неизвестные свидетельства перехода позднепалеолитического человека от охоты на крупных животных к охоте на небольших нестадных животных в северо западном Причерноморье Начало средиземноморской трансгрессии и миграции средиземноморской биоты произошли около 9,5 т. л. н. Развитие трансгрессии и мигация фауны имели возвратно поступательном характер и происходили в течение шести трансгрессивно-регресивных стадий. Мезолитические стоянки продолжали располагаться вдоль речных долин и несут следы перехода от охоты до сбора съедобных растений. Никаких признаков катастрофического затопления Черного моря в раннем голоцене не обнаружено.
