“…1(a) and (b)); previously such deposits were known only from the Witham-Trent, downstream of the Lincoln Gap Sumbler, 1988, 1991). Little evidence has been found for post-Anglian-pre-Devensian glaciation of the modern Middle Trent catchment, as invoked by previous authors to explain the paucity of sites representing the earlier post-Anglian interglacials (Straw, 1979;cf. Howard et al, 2007).…”

Data amassed in the past decade on Quaternary fluvial archives has allowed comparison across widely separated regions of the world. Meanwhile there has been a new impetus for research on British sequences, as a result particularly of the Aggregates Levy Sustainability Fund (ALSF). In this context, the key British records (from the Thames, Severn-Avon, Trent, Wash system and Solent) are described briefly, with emphasis on the latest information. In the case of the Trent, sedimentary evidence, discovered during ALSF-funded work, appears to confirm the existence of a Middle Pleistocene 'Trent-Ancaster' River. In the case of the Solent, independent projects that sought to improve the age constraint for the sequence have produced complimentary results; the first used luminescence dating, whereas the second made use of Palaeolithic evidence to calibrate numerical incision/uplift modelling. The overarching message is that the British fluvial archive can be readily understood within a global context; it typifies records from areas with relatively young crust that has been uplifting during the Quaternary and, being in the temperate latitudes and close to the Atlantic margin, it reflects strong climatic forcing. The combination of rich faunal and Palaeolithic artefact contents means that certain British records are of international significance.

“…The main evidence are summarised in Bowen et al (1986) and in Knight et al (2004). Initially, the 'modern' model for glaciation over this period consisted of two lowland glaciations (Mitchell et al, 1973): an earlier Anglian Glaciation equated with the Elsterian of Europe and a Wolstonian Glaciation equated with the Saalian (Shotton, 1976(Shotton, , 1983Straw, 1979) ( Figure 4A) and these are cited in the most recent stratigraphic scheme for the British Quaternary (Bowen, 1999). The Anglian is defined by a stratotype at Corton near Lowestoft in East Anglia (Pointon, 1978) and the Wolstonian by a stratotype at Wolston near Coventry in midland England (Shotton, 1976(Shotton, , 1983) ( Figure 4A).…”

This paper presents the outcome of a workshop, held in Berlin in February 2009, concerned with current research on the glacial history of northern Europe, including the British Isles. The methodologies presently used to resolve this topic are outlined. Particular attention is given to new analytical methods deriving from high resolution remote imaging of glacial terrain both on land and on the sea-bed, key new stratigraphic sections, higher resolution results from conventional geochronological methods like radiocarbon and more recently developed technologies such as luminescence and cosmogenic radionuclide dating. The relationships between the results derived from these two methods are discussed in further detail along with possible explanations for these differences. An outline of a 'most likely' glacial history of the Scandinavian and British and Irish Ice Sheets is presented along with possible links to global climate change as represented by the marine isotope (MIS) record. Tentative evidence for glaciation is identified in MIS 22, 16, 12, 10, 8, 6, 4 and 2 and correlations of 'phases' within the Last Glaciation are also explored for both the Scandinavian and British and Irish Ice Sheets. The results show that the character and extent of glaciation in different parts of the region are not synchronous and much more geochronological work is required before regional correlations can be established with confidence. Keywords: glaciation, marine isotope stages (MIS), Scandinavian Ice Sheet (SIS), British and Irish Ice Sheet (BIIS), Last Glacial Maximum Introduction and objectivesThe glaciation of northern Europe has been a subject of interest and debate for over 200 years and today, at a time of greater awareness to the consequences of climate change, the subject retains its relevance to science and society. With the development of new methodologies for dating glacial deposits and important new findings for modelling glacier response to climate change this subject requires re-evaluation and re-interpretation. Likewise it has been possible to identify critical issues that should be the focus for future research. Consequently, in February 2009 an exploratory workshop was held at the Freie Universität Berlin to examine the frequency and timing of glaciations in northern Europe (including Britain) during the Middle and Late Pleistocene. The workshop was funded by the DFG (Deutsche Forschungsgmeinschaft/ German Research Foundation) and involved 24 participants. This issue of Quaternary Science Reviews includes a number of the contributions presented and discussed at the meeting along with certain invited papers that present new findings on the topic of the special issue. This paper will begin by briefly reviewing the contents of the issue giving particular attention to new and important findings. This will be followed by a section that will evaluate the methodologies currently being applied to understand the glaciations of northern Europe. Some of these methodologies, such as lithostratigraphy and morphostratig...

“…Without this stratigraphical control, it is unclear in which of the LFt units the erratics were found, militating against the value of the data set. In a number of detailed, stratigraphically controlled, erratic provenance studies, Straw (1979Straw ( , 1983Straw ( , 1991 demonstrate southerly ice-flow in Lincolnshire, contrary to that in both the Perrin et al (1979) and Rose (1992) models (Figure 1b and c). Straw's studies relied upon small outcrops of a few distinctive Jurassic and Cretaceous rocks, found in Lincolnshire (see Hallam, 1992;Rawson, 1992), to provide evidence of iceflow direction mainly in the northern part of the region under consideration here.…”

The distribution and deposits of British and Scandinavian Middle Pleistocene ice sheets in eastern England remain problematic. A new till provenancing technique based on Chalk micropalaeontology is described, with the object of refining understanding of the ice sheet which deposited the Lowestoft Formation till (Anglian/Elsterian) and its relationship to Scandinavian ice sheets. The technique involves extracting foraminifera from Chalk erratics and till matrix obtained from stratigraphically controlled till sections and comparing their micropalaeontology with that of Upper Cretaceous Chalk bedrock. Application to the Lowestoft Formation till of eastern England suggests that current models of ice-flow in this region require revision involving reinstatement of some earlier ideas. Chalk provenance data indicate an initial phase of glaciation, with ice streaming southwards across eastern England before fanning across East Anglia from the position of the Fen basin. This was followed by a later phase in which the main southward trajectory of ice-flow was located further east in the North Sea Basin, but again with ice fanning out across East Anglia. These ice-flow trajectories imply constraint of the British ice sheet by Scandinavian ice.
