Pollen and grain size records in abyssal sediments of the northwest Pacific Ocean as proxies of Plio-Pleistocene climate change /
… mid-latitude North Pacific and its relation to climate change in East Asia since the mid-Pliocene. Dust-sized particles (including pollen), sourced from the arid regions and loess plateaus in East Asia are entrained by prevailing westerly winds and transported to the midlatitude northwest North …

Assessing Pleistocene climate on the Southern High Plains through geochemical and physical characteristics of paleosols archived in the Blackwater Draw Formation
… used to interpret on climatic conditions of the Pleistocene. Petrographical and geochemical evidence indicates five buried soils (buried soil 5 = oldest to buried soil 1=youngest) are present in the Type Section of the Blackwater Draw Formation. Buried soils 4 and 5 are classified as Aridisols …

Reconstruction of the Late and Mid-Pleistocene climate and landscape history in SE-Central Europe - A paleopedological and geochemical multi-proxy approach in loess-paleosol studies.
… to the reconstruction of the Mid- and Late Pleistocene climate and landscape history of the region by a paleopedological – geochemical multi-proxy approach. Furthermore, methodological investigations aim to evaluate the validity of various paleoenvironmental proxies especially geochemically …

BERINGIAN BIOGEOGRAPHY: PATTERNS OF INTERCONTINENTAL DISPERSAL AND THE STRUCTURING OF A HOLARCTIC TAPEWORM GENUS
… and closing of the Bering Land Bridge due to Pleistocene climate fluctuations facilitated the exchange of taxa between the Palearctic and Nearctic. While many studies have worked toward elucidating the role of Beringia in assembling northern faunas, relatively little work has focused on …

Seasonal rainfall regime modulates genetic variation in the moss Pseudocrossidium crinitum
… of genetic variation, resulting from Pliocene-Pleistocene climate shifts have been largely documented for species from Europe. However, little is known from Africa and especially South Africa, where climate shifts have often been invoked to explain the amazingly high diversity of the Cape …

Analysis of deposition, erosion, and landscape stability during the late Quaternary using multi-proxy evidence from Owl Creek, Central Texas, USA.
… wetter conditions as recorded by regional climate proxies. Compilation of the proxies presented shows evidence for a cooler and wetter late Pleistocene climate, followed by a warmer and drier climate dominating during the Holocene. Regional proxies become more abundant into the Holocene …

Sedimentology and micropalaeontology of gravity cores from the N.E. Atlantic continental slope south west of Ireland
… found to document the major trends of the Late Pleistocene climate. Several stratigraphic indicators; - carbonate content, sediment texture, grain size, composition, nature of terrigenous components, ice-rafted debris and foraminiferal diversity were examined and show that the glacial history of …

Speleogenetic Evolution and Geological Remote Sensing of the Gypsum Plain, Eddy County, New Mexico
… and additional hypogene porosity development. Pleistocene climate fluctuations increased denudation and exposed Castile evaporites to epigene development, while migration of the Pecos River across the area during the late Eocene enhanced karst processes. Karsting slowed with the Holocene shift …

Slip rate of the West Tahoe Fault and the age of glacial deposits near Lake Tahoe, California
… Tahoe City. The West Tahoe Fault displaces late Pleistocene moraines and glacial deposits along much of its extent. Terrestrial Cosmogenic Nuclide (TCN) surface exposure ages of sixteen boulders were collected from faulted moraines at Cascade Lake. Eight ages from the last-glacial Tioga moraine …

Subsurface Geophysical Investigations of Oneida Lake Ny: Insights Into Ice Sheet Processes and Deglaciation At Termination I
… (LIS) provides insight into understanding end-Pleistocene climate, a critical set of boundary conditions prior to the onset of Holocene climates that were optimal for human dispersal and societal growth. Constraining ice sheet dynamics, glacier retreat rates, and the timing of still-stands and …
