Clarke M.L.; Rendell H.M. (2006)

Holocene forested coastal dunes fringe the Atlantic coast of western Portugal. Mapping of dunes in the field and using air photographs shows a range of forms reflecting dominant northwest and westerly onshore wind regimes. ...
HIGH-PRESSURE BEHAVIOR OF MNGEO3 AND CDGEO3 PEROVSKITES AND THE POST-PEROVSKITE PHASE TRANSITION

Tateno Sh.; Hirose K.; Sata N.; Ohishi Ya. (2006)

The stability and high-pressure behavior of perovskite structure in MnGeO3 and CdGeO3 were examined on the basis of in situ synchrotron X-ray diffraction measurements at high pressure and temperature in a laser-heated ...
TREE-RING EVIDENCE OF ‘LITTLE ICE AGE' GLACIER ADVANCES IN SOUTHERN TIBET

Brauning A. (2006)

The history of late Holocene glacier fluctuations in eastern Tibet was studied by determining the ages of trees growing on glacier deposits. Maximum tree ages yield minimum ages of AD 1760 and 1780 for moraine formation ...
WINTER AND SUMMER CLIMATE PATTERNS IN THE EUROPEAN-MIDDLE EAST DURING RECENT CENTURIES AS DOCUMENTED IN A NORTHERN RED SEA CORAL RECORD

Rimbu N.; Felis T.; Lohmann G.; PAatzold Ju. (2006)

The Ras Umm Sidd coral 6180 record from the northern Red Sea is the northernmost centuries long coral time series that is currently available in seasonal resolution (AD 1750-1995). Here we investigate climate patterns ...
CUPRESSUS DUPREZIANA: A DENDROCLIMATIC RECORD FOR THE MIDDLE-LATE HOLOCENE IN THE CENTRAL SAHARA

Cremaschi M.; Pelfini M.; Santilli M. (2006)

Dendroclimatology of Cupressus dupreziana, the Tassili cypress, has been attempted on samples obtained from the door beams of the old cities of Ghat and Barkat located at the foot of the Tassili, where the cypress still ...
THE EFFECT OF CLIMATE VARIABILITY ON POLLEN PRODUCTIVITY, AD 1975-2000, RECORDED IN A SPHAGNUM PEAT HUMMOCK

Sjogren P.; van Leeuwen Ja.F.N.; van der Knaap W.O.; van der Borg K. (2006)

Pollen accumulation rates and pollen percentages from a Sphagnum peat hummock in the Jura Mountains were used to determine past pollen deposition. Post-bomb calibrated radiocarbon dates allowed estimations of annual ...
LONG-DISTANCE TRANSPORT OF MACROSCOPIC CHARCOAL BY AN INTENSIVE CROWN FIRE IN THE SWISS ALPS - IMPLICATIONS FOR FIRE HISTORY RECONSTRUCTION

Tinner W.; Hofstetter S.; Zeugin F.; Conedera M.; Wohlgemuth T.; Zimmermann L.; Zweifel R. (2006)

The correct interpretation of charcoal records in a palaeoecological context requires the understanding of the sources and transport of charcoal particles. Conventionally, it is assumed that macroscopic charcoal particles ...
THE DEVELOPMENT OF PASTURE WOODLAND IN THE SOUTHWEST SWISS JURA MOUNTAINS OVER 2000 YEARS, BASED ON THREE ADJACENT PEAT PROFILES

Sjogren P. (2006)

The pollen content of three adjacent peat profiles has been analysed to study the development of pasture woodland in the small valley Combe des Amburnex (1300 m a.s.l.). Chronostratigraphy based on lowland pollen assemblages ...
THE HOLOCENE VEGETATION HISTORY OF LAKE ERHAI, YUNNAN PROVINCE SOUTHWESTERN CHINA: THE ROLE OF CLIMATE AND HUMAN FORCINGS

Shen Ji.; Jones R.T.; Yang X.; Dearing J.A.; Wang S. (2006)

A pollen diagram from a 6.62 m sediment sequence in Lake Erhai in northwest Yunnan, China was obtained to examine the roles of climate change and human impact on the development of the Erhai lake-catchment system since ...
EXTENSION OF THE NEW ZEALAND KAUR (AGATHIS AUSTRALIS) CHRONOLOGY TO 1724 BC

Boswijk G.; Fowler A.; Lorrey A.; Palmer J.; Ogden J. (2006)

Long tree-ring chronologies have been constructed in the Northern Hemisphere for dendroclimatology and palaeoenvironmental studies, radiocarbon calibration and archaeological dating. Numerous tree-ring chronologies have ...
THE USE OF FOSSILIZED HONEY FOR PALEOECOLOGICAL RECONSTRUCTION: A PALYNOLOGICAL STUDY OF ARCHEOLOGICAL MATERIAL FROM GEORGIA

Kvavadze E.V. (2006)

Palynological analysis of the organic contents of ceramic pots from the Kodiani burial mound, which is dated as 27th-25th centuries B.C., revealed that they contained honey. The samples are extremely rich in excellently ...
NORTH AMERICAN DROUGHTS OF THE MID TO LATE NINETEENTH CENTURY: A HISTORY, SIMULATION AND IMPLICATION FOR MEDIAEVAL DROUGHT

Herweijer C.; Seager R.; Cook E.R. (2006)

Unlike the major droughts of the twentieth century that are readily identified in the instrumental record, similar events in the nineteenth century have to be identified using a combination of proxy data, historical accounts ...
RAPID CLIMATE CHANGE DURING THE EARLY HOLOCENE IN WESTERN EUROPE AND GREENLAND

Prasad S.; Brauer A.; Rein B.; Negendank J.F.W. (2006)

Based on microfacies analyses of seasonally laminated varved sediments from lake Holzmaar, Germany, we report evidence of decadal-to century-scale climate variability during the early Holocene. The shifts in climate are ...
SUCCESSIVE FORAMINIFERAL FAUNAS AND INFERRED PALAEOENVIRONMENTS ASSOCIATED WITH THE POSTGLACIAL (HOLOCENE) MARINE TRANSGRESSION, GULF ST VINCENT, SOUTH AUSTRALIA

Cann J.H.; Murray-Wallace C.V.; Riggs N.J.; Belperio A.P. (2006)

Gulf St Vincent is one of a pair of elongate, triangular, shallow water embayments into the southern coast of continental Australia. From the southern floor of this embayment, within a shallow basin-like depression where ...
HOLOCENE FIRE IN THE SCOTTISH HIGHLANDS: EVIDENCE FROM MACROSCOPIC CHARCOAL RECORDS

Froyd C.A. (2006)

It has been hypothesized that the mid-Holocene decline of pine (Pinus sylvestris L.) woodland in the Scottish Highlands may have been the result of a change in the fire regime of the region. Little is known about the ...
RECONSTRUCTION OF HOLOCENE MONSOON HISTORY FROM THE PEARL RIVER ESTUARY, SOUTHERN CHINA, USING DIATOMS AND CARBON ISOTOPE RATIOS

Zong Y.; Lloyd J.M.; Leng M.J.; Yim W.W.S.; Huang G. (2006)

This study employs a multiproxy approach in the reconstruction of Holocene monsoon history from sedimentary sequences obtained from the Pearl River Estuary, southern China. A set of modern surface sediment samples were ...
A HIGH MOUNTAIN POLLEN-ALTITUDE CALIBRATION SET FOR PALAEOCLIMATIC USE IN THE TROPICAL ANDES

Rull V. (2006)

The numerical relationship between modem pollen assemblages and altitude in high mountain environments from the northern Andes is analysed, in order to found inference models that allow estimating palaeoaltitudes and ...
VARIABILITY IN NORTH ATLANTIC MARINE RADIOCARBON RESERVOIR EFFECTS AT C. AD 1000

Ascough P.L.; Cook G.T.; Church M.J.; Dugmore A.J.; Arge S.V.; McGovern T.H. (2006)

14C age measurements made on samples from three archaeological sites located on North Atlantic coasts were used to investigate the marine reservoir effect (MRE) at c. AD 1000. This is an important period within human ...
SURFACE EXPOSURE DATING OF MORAINES IN THE KROMER VALLEY (SILVRETTA MOUNTAINS, AUSTRIA)-EVIDENCE FOR GLACIAL RESPONSE TO THE 8.2 KA EVENT IN THE EASTERN ALPS?

Kerschner H.; Hertl A.; Gross G.; Ivy-Ochs S.; Kubik P.W. (2006)

10Be dating of a pronounced glacier advance (‘Kromer Stadial’) in the western part of the Silvretta Mountains (western Austria) yielded ages ranging from 8010±360 to 8690±410 years with a mean age for moraine stabilization ...
