  • Paleoclimatic record of speleothems in a tropical region

  • Late Holocene Paleoclimatic Changes in Western Central Africa Inferred from Mineral Abundance in Dated Sediments from Lake Ossa (Southwest Cameroon)

    Open AccessDenis Wirrmann, Jacques Bertaux et al.ARTICLEQuaternary Research2001

    Minerals derived from catchment soils were determined using FTIR spectroscopy in the well-dated core OW4 from Lake Ossa, a lowland rainforest area in Cameroon. This quantification provides a hydrologic record indicating that the magnitude of runoff events, and by inference, rainfall pattern, has varied during the Late Holocene. The comparison between minerogenic inputs and vegetation changes improves the understanding of the inferred climate dyna…

  • The tempo of Holocene climatic change in the eastern Mediterranean region

    Open AccessNeil Roberts, Jane M Reed et al.ARTICLEThe Holocene2001Cited by: 47References: 10

    This study presents results from a multi-proxy analysis of cores taken in a crater-lake sequence from Eski Acigöl in centr-al Turkey which cover the period from pre-c. 16000 cal. yr BP to the present. The sediments comprise an upper unit of enerally non-laminated, banded to massive silts and peats of mid- to late-Holocene age, overlying a laminated unit of late-Pleistocene to early/mid-Holocenie age. The laminae, comprising mainly aragonite. amor…

  • Late Holocene Climatic Changes in Western Equatorial Africa Inferred from Pollen from Lake Sinnda, Southern Congo

    Open AccessAnnie Vincens, Dominique Schwartz et al.ARTICLEQuaternary Research1998

    Pollen analysis of two cores from the Lake Sinnda, located in one of the driest areas of the southern Congo, reveals a history of vegetation and climate in this region during the past 5000 yr. A major change centered around 3000–2500 yr B.P. is indicated by an abrupt decrease in forest pollen and by a corresponding increase in grassland pollen. Concurrent drying up of the lake shows that climate, in particular aridity, was the major cause of this…

  • Absence of Last Glacial Maximum Records in Lowland Tropical Forests

    Open AccessMarie-Pierre Ledru, Jacques Bertaux et al.ARTICLEQuaternary Research1998

    Environmental conditions of the lowland tropical forests during the last glacial maximum (LGM) between ca 20,000 and 18,000 14 C yr B.P., are reevaluated in terms of dating control and lithology analyzed in seven pollen records from South America. The reevaluation shows that probably in none of the published records are LGM sediments present or abundant. This conclusion is based on the occurrence of abrupt lithologic changes coupled with changes …

  • Perturbaciones del régimen de las lluvias y condiciones de tipo El Niño en América del Sur tropical desde hace 7000 años

    Open AccessLouis Martin, Jacques Bertaux et al.ARTICLEBulletin de l’Institut français…1995

    Disturbance of rainfall regime and El Niño-like conditions in tropical South America during the last 7000 years Sedimentary records from three geographically and climatically distinct South American areas allowed the reconstruction of the rainfall regime during the last 7 000 yrs. In south-eastern Amazonia, palynological and sedimentological analyses from cores retrieved in lakes of Carajás region (6o S) demonstrated the existence of several peri…
