TL;DR: In this paper, a process-based summary of the multiple controls on speleothem oxygen-isotope values (d 18 O) in the atmosphere, soil, epikarst, and calcite, illustrated with case studies is presented.

TL;DR: In the case of speleothem Mg, a number of case studies have effectively used trace elements such as speleotiem Mg as records of palaeo-aridity, using supporting arguments from modern monitoring or covariations with other parameters such as stable isotopes as discussed by the authors.

TL;DR: A review of the most important existing approaches for reconstructing fire history at centennial to millennial scales can be found in this paper, where the authors suggest that emphasis should be laid on discriminating natural from anthropogenic fire-regime types, and improving combined analysis of fire and vegetation reconstructions to study long-term fire ecology.

TL;DR: In the early Holocene, the Egesen stadial moraines can be divided into three or in some cases even more phases (sub-stadials) as mentioned in this paper.

TL;DR: This article analyzed published records of terrigenous dust flux from marine sediments off subtropical West Africa, the eastern Mediterranean Sea, and the Arabian Sea and lake records from East Africa using statistical methods to detect trends, rhythms and events in Plio-Pleistocene African climate.

TL;DR: In this paper, the results of an investigation of the Weichselian Upper Pleniglacial loess sequences of Nussloch (Rhine Valley, Germany) based on stratigraphy, palaeopedology, sedimentology, palynology, malacology and geochemistry (δ 13 C), supported by radiocarbon, TL and OSL dating are reported.

TL;DR: In this paper, a suite of forward transient numerical modeling experiments of the British and Irish Ice Sheet (BIIS), consisting of Scottish, Welsh and Irish accumulation centres, spanning the last Glacial period from 38 to 10 ka BP, are presented.

TL;DR: Based on a revised chronostratigraphy, and compilation of borehole data from the Barents Sea continental margin, a coherent glaciation model is proposed for the barents sea ice sheet over the past 3.5 million years (Ma) as mentioned in this paper.

TL;DR: In this paper, the same authors compared two fractions of the same charcoal samples derived from a series of superimposed Mousterian, Aurignacian and Gravettian levels excavated at the Grotta di Fumane, in northern Italy.

TL;DR: In this article, a database of late-Quaternary plant macrofossil records for northern Eurasia (from 23° to 180°E and 46° to 76°N) comprising 281 localities, over 2300 samples and over 13,000 individual records is presented.

TL;DR: In this article, the authors present the results of the palynological and diatom analyses of the sediment core recovered in Hoton-Nur Lake (48°37′18″N, 88°20′45″E, 2083m) in 2004.

TL;DR: A simple graphical method is developed to test if spatial autocorrelation affects a training set, a Monte Carlo geostatistical simulation is developed as a null model to test the significance of transfer functions in Autocorrelated environments, and a cross-validation scheme is introduced that is more robust to autoc orrelation.

TL;DR: In this article, four large landslides, each with a debris volume >10 6 m 3, in the Himalaya and Transhimalaya of northern India were examined, mapped, and dated using 10 Be terrestrial cosmogenic radionuclide surface exposure dating.

TL;DR: In this paper, a systematic program of drumlin mapping from digital elevation models and satellite images of Britain and Ireland was used to compile a range of statistics on length L, width W, and elongation ratio E (where E = L/W) for a large sample.

TL;DR: In this paper, a compilation of new and previously published ice-rafted detritus (IRD) flux and concentration data from high-resolution sediment cores recovered from the NE Atlantic deep-sea continental slope adjacent to the last British-Irish Ice Sheet (BIIS) is presented.

TL;DR: In this paper, the authors constrain a three-dimensional thermomechanical model of Greenland ice sheet (GrIS) evolution from the Last Glacial Maximum (LGM, 21 ka BP) to the present-day using, primarily, observations of relative sea level (RSL) as well as field data on past ice extent.

TL;DR: The timing and extent of latest Pleistocene and Holocene alpine glacier fluctuations in the Himalaya and Tibet are poorly defined due to the logistical and political inaccessibility of the region and the general lack of modern studies of the glacial successions as mentioned in this paper.

TL;DR: In the early Holocene abrupt, decadal to centennial-scale climate variations caused significant glacier variations in Norway as mentioned in this paper during the early/mid-Holocene, and increased freshwater inflow to the North Atlantic and Arctic Oceans has been suggested as one of the most likely mechanisms to explain the abrupt and significant Lateglacial and early holocene climatic events in NW Europe.

TL;DR: In this paper, the authors used a new sedimentary record to reconstruct the Holocene vegetation and fire history of a coastal lake in south-western Sicily (Italy) and concluded that under (semi-)natural conditions evergreen broadleaved Q. ilex and O. europaea forests would still dominate near Gorgo Basso.

TL;DR: In this article, the authors summarize evidence of the latest Pleistocene and Holocene glacier fluctuations in the Canadian Cordillera and present a review focusing primarily on studies completed after 1988, when the first comprehensive review of such evidence was published.

TL;DR: The influence of the northern Atlantic and tropical monsoonal systems, as recorded by the River Nile, on the climate variability of the southeastern Mediterranean was studied in two cores taken by the R/V Marion Dufresne.

TL;DR: In this paper, high-resolution mass accumulation rates (MAR) and X-ray fluorescence (XRF) measurements from marine sediment records in the Bay of Biscay (NE Atlantic) have allowed the determination of the timing and the amplitude of the Channel River discharges during glacial stages MIS 10, MIS 8, MIS 6 and MIS 4-2.

TL;DR: In this paper, the authors integrated analyses of sedimentary facies, diatom assemblages, and radiocarbon dates for three drill cores from the lowland to demonstrate Holocene sedimentary evolution in relation to sea-level changes.

TL;DR: In this paper, the authors collected 50 seismic profiles with a total length of similar to 850 km to identify continuous undisturbed sedimentary sequences for potential ICDP locations, and cored 10 different locations to water depths of up to 420 m.

TL;DR: In this article, a multiresolution analysis of sediment cores recovered in karstic Lake Estanya (42°02′ N, 0°32′ E; 670 m a. s. l., NE Spain), located in the transitional area between the humid Pyrenees and the semi-arid Central Ebro Basin, provides the first high-resolution, continuous sedimentary record in the region, extending back the last 21,000 years.

TL;DR: In this paper, the authors consider the response of marshland to accelerations in the rate of sea-level rise by utilizing two previously described numerical models of marsh elevation, and find that they predict surprisingly similar responses to sea level change.

TL;DR: The evolutionary and biogeographic history of the contemporary Antarctic terrestrial and marine biotas reveals many components of ancient origin this paper, and for large elements of the terrestrial biota, long-term isolation over timescales from hundreds of thousands to tens of millions of years, and thus persistence through multiple glacial cycles, is the norm rather than the exception.

TL;DR: The authors synthesize a new fluvial terrace chronostratigraphy of the Bidente and Musone Rivers cast within a broader European framework, which forms the basis of a terrace genesis and river incision model for the northern Apennines, Italy.

TL;DR: In this article, multiproxy climate records from Iceland reveal complex changes in terrestrial climate and glacier fluctuations through the Holocene, revealing some coherent patterns of change as well as significant spatial variability.
