Comparison of the marine oxygen isotope record, the eustatic sea level record, and the chronology of glaciation in the United States of America in Quaternary glaciations in the Northern Hemisphere.
Paleoclimatic significance of the mineral magnetic record of the Chinese loess and paleosols
estimates of the major magnetic components. The AA. identify pedogenic formation of magnetite as the major contributor to the loess magnetic record. Matching this record against other paleoclimatic records, they find an high correlation with the standard 18O
record. The Chinese loess sequences record a very high resolution magnetic stratigraphy directly related to changing climate.
Natural environmental change in karst: the Quaternary record
The purpose of this paper is to present a summary of the natural paleoclimatic records derived from karst research: the marine record, caves as data bases, chronology of the speleothem record, implications of speleothem age frequency distributions
, glacio-eustatic sea level history, speleothems and the stable isotope record, relict and inherited karst morphology.
Climatic change on the Iberian Peninsula recorded in a 30 000 yr pollen record from Lake Banyoles
The Banyoles lacustrine sequence shows that the vegetational history of the northeastern Iberian Peninsula during the last 30 000 yr follows the North Atlantic pattern of climatic oscillations. This high-resolution record contains well-preserved
fossil remains that provide paleoenvironmental information and authigenic calcite for U-series dating. U/Th dates furnish calendar ages and allow correlation between deglacial paleoceanographic models and continental paleoclimatic records.
Climatic fluctuations in northern Patagonia during the last 1 000 years as inferred from tree-ring records
A multiple regression model is used to reconstruct summer temperature departures in northern Patagonia on the basis of tree-ring data. Finally, the temperature reconstruction is compared with other proxy records of climatic variation in Patagonia
to assess its correspondence to local climatic records.
Paleohydrological records from peat profiles and speleothems in Sutherland, northwest Scotland
This paper provides independent paleohydrological data from widely spaced replicate profiles from a Scotish peatland and compares these with the paleoenvironmental records of a nearby cave and its overlying peat. The main aim is to test
the hypothesis that the records represent a regional paleoclimate record between 1800 and 2400 cal yr B.P.
A speleothem record of Younger Dryas cooling, Klamath Mountains, Oregon, USA
The AA. develop a precisely dated isotope record (δO 18, δC 13) of the last deglaciation from a stalagmite recovered from the Klamath Mountains, southwestern Oregon. Since the climate of the region is strongly influenced by the Pacific Ocean
, this record is significant in providing one of the few precisely dated terrestrial record of Northeast Pacific climate variability during the last deglaciation.
Temperature proxy records covering the last two millennia : a tabular and visual overview
Here, the first systematic survey is presented, with graphic representations, of most quantitative temperature proxy data records covering the last two millennia that have been published in the peer-reviewed literature. In total, 71 series
are presented together with basic essential information on each record. This overview will hopefully assist future palaeoclimatic research by facilitating an orientation among available palaeotemperature records and thus reduce the risk of missing less well
-known proxy series. Both the Medieval Warm Period, the Little Ice Age and the 20th century warming are clearly visible in most records, whereas the Roman Warm Period and the Dark Age Cold Period are less clearly discernible.
Biogenic silica record in Lake Biwa of central Japan over the past 145,000 years
The record of the biogenic silica flux (BSF) in Lake Biwa reflects changes in diatom productivity in the lake and provides information regarding changes in paleoclimatic conditions. The BSF record of Lake Biwa demonstrates 5 periods over the past ca
. 145,000 yr and 5 intervals. Time series of the BSF record can be correlated with the record of biogenic silica content in Lake Baikal and the marine oxygen isotopes stages 1 through 6. Furthermore, the BSF values varied with much higher amplitude during
Analysis of daily and monthly spatial variance components in historical temperature records
The purpose of this paper is to examine changes in the spatial variance of mean monthly and daily temperatures that may have occurred during the period of historical records. The northern hemispheric lower-tropospheric satellite-based temperature
records from 1979 to 1996 and the near-surface air temperature records from either 1947 to 1996 or 1897 to 1996 show relatively consistent temporal patterns with respect to spatial variance. Overall, the spatial variance in temperature anomalies has
declined during the period of historical records and spatial variance is negatively related to mean hemispheric temperature. These results are consistent with model predictions.
Ice-core pollen record of climatic changes in the central Andes during the last 400 yr
This paper presents a high-resolution ice-core pollen record from the Sajama Ice Cap, Bolivia, that spans the last 400 yr. The pollen record corroborates the oxygen isotopic and ice accumulation records from the Quelccaya Ice Cap in southern Peru
and supports the scenario that the Little Ice Age (LIA) consisted of 2 distinct phases, a wet period and a dry period. The striking similarity between the Sajama and Quelccaya proxy records suggests that climatic changes during the Little Ice Age occurred
Surface-based observations of total cloud amount have been collected from historical records for four continents : North America, Europe, India and Australia. The records extend from 1900 to around 1985. 86 % of the 350 individual station records
Investigations of the past record of fault displacements have traditionally employed only the manifestation of displaced rock masses or palaeoseismological indications of strong ground motion. However the hydrogeological changes that accompany
earthquakes also have the potential to leave a record in the rock, chiefly in the form of mineral precipitates. A new branch of neotectonics is proposed: neohydrotectonics concerned with the fossil record of hydrogeological changes that have accompanied
Lacustrine sedimentary record of ice-dammed neoglacial Lake Alsek
This paper is concerned with the stratigraphy and facies analysis of Lake Alsek sediments. Discussion focusses on vertical facies relationships and seeks to determine what sedimentary record has been preserved. This analysis is part of a synthetic

Stratigraphic and petrographic study of foredeep molasse sediments, which provide a detrital record of the evolution of the southern Himalayas during the tectonic collision of central Asia and India.
