This chapter reviews the evidence for glacial limits in England, Scotland, and Wales as understood at the beginning of 2002. Evidence for glaciation of England, Scotland, and Wales is primarily lithological with glacial episodes being identified by till and glaciofluvial sediments and glacial limits being determined by the extent of these deposits. Additionally, geomorphological evidence has played an important role in reconstructing the extent of ice masses in younger glaciations. Moraine ridges and ice-contact landforms, including patterns of glacio-isostatically deformed displaced shorelines, have played an important role in the determination of ice limits of these younger glacial events. Biological evidence has played a role in separating glacial events and in indicating a tendency toward climatic deterioration, or the existence of cold conditions that may be associated with glaciation. In the majority of cases, this biological evidence has taken the form of pollen, but molluska and plant macros have also been used to differentiate different stages of the Quaternary and insect faunas to provide direct evidence for the presence of glacial meltwater. Soil evidence, usually in the form of permafrost structures, has been used to indicate cold climate conditions that have been linked with the formation of glacier ice elsewhere in England, Wales, and Scotland.read more

TL;DR: In this paper, the maximum limits of the Eurasian ice sheets during four glaciations have been reconstructed: (1) the Late Saalian (>140 ka), (2) the Early Weichselian (100-80 ka),(3) the Middle Weichsellian (60-50 ka), and (4) the late Weichselsian (25-15 ka) based on satellite data and aerial photographs combined with geological field investigations in Russia and Siberia, and with marine seismic and sediment core data.

Pattern and timing of retreat of the last British-Irish Ice Sheet
TL;DR: In this paper, the authors reconstruct the demise of the British-Irish Ice Sheet (BIIS) and present palaeo-glaciological maps of retreat stages between 27 and 15 ka BP.

The extent and chronology of Cenozoic Global Glaciation
Jürgen Ehlers,Philip L. Gibbard +1 more
TL;DR: The Quaternary is synonymous with extensive glaciation of Earth's mid-and high-latitudes as discussed by the authors, and significant glaciation began in the latest Eocene (ca 35-Ma) in eastern Antarctica, followed by glaciation in mountain areas through the Miocene (in Alaska, Greenland, Iceland and Patagonia), later in the Pliocene (e.g. in the Bolivian Andes and possibly in Tasmania) and in the earliest Pleistocene (i.e.

Ancient Hybridization and an Irish Origin for the Modern Polar Bear Matriline

TL;DR: The reconstructed matrilineal history of brown and polar bears has two striking features: first, it is punctuated by dramatic and discrete climate-driven dispersal events, and second, opportunistic mating between these two species as their ranges overlapped has left a strong genetic imprint.

Late Pleistocene evolution of the Rhine-Meuse system in the southern North Sea basin: imprints of climate change, sea-level oscillation and glacio-isostacy

TL;DR: In this paper, high-resolution continuous core material, geophysical measurements and hundreds of archived core descriptions enabled to identify 13 Late Pleistocene Rhine-Meuse sedimentary units in the infill of the southern part of the North Sea basin (the Netherlands, northwestern Europe).

Nunataks of the last ice sheet in northwest Scotland
TL;DR: In this paper, high-level weathering limits separating ice-scoured topography from an upper zone of frost-weathered detritus were identified on 17 mountains in NW Scotland at altitudes of 500 m over the extreme NW tip of Scotland and to 700-730 m at the head of Little Loch Broom.

The Middle Pleistocene of North Birmingham
TL;DR: The older drift of north Birmingham infills a system of pre-glacial valleys as discussed by the authors and its stratigraphy has been worked out, chiefly from borehole records, showing it to comprise the deposits of two separate glaciations-the Lower and Upper Glacial Series, and an intervening Interglacial Series.

Geochemistry and radiometric dating of a Middle Pleistocene peat
TL;DR: Uranium, lead, and sulphur data for a Middle Pleistocene interglacial peat deposit from Norfolk, UK, suggest that uptake of these elements was synchronous and confined to a single early diagenetic episode, probably coeval with peat formation as discussed by the authors.

Middle Pleistocene drainage in the Thames Valley
TL;DR: In this paper, it was shown that the diversion of the Mole-Wey tributary by the Anglian chalky till ice parallel those of the Thames in the Vale of St Albans and suggest that similar events may also have occurred in other S bank tributaries to the E.

Testing the case for a Middle Pleistocene Scandinavian glaciation in Eastern England: evidence for a Scottish ice source for tills within the Corton Formation of East Anglia, UK
TL;DR: In this paper, the authors investigated the provenance of the Happisburgh Till and Corton Till of the Corton Formation using erratic clast lithologie s and allochthonou s palynomorph s to test whether the long held assumption that they were deposited by ice that originated in Scandinavia is valid.
