Abstract

We present a collation of 975 published dates relevant to the timing of build-up and retreat of ice overthe British Isles during the most recent glacial stage. The spatial distribution of dates is essential tointerpreting the evolution of the ice sheet over time and space. For this reason the dates are presentedas a map showing the spatial distribution across the UK and Ireland. Full documentation for each date,attributed to its source publication and detailing geographic location, the material dated, its stratigraphicposition or setting, the dating technique, the dating result, errors and calibration, and comments pertinentto its interpretation, are included in the accompanying table. It is anticipated that this dataset will be auseful resource for Quaternary research in the UK and Ireland and is therefore available to download asa shapefile and/or PDF file. The map is presented at a scale of 1: 2,700,000, designed to be printed at A2size.

1. Introduction

Geochronology is an essential tool for ice sheet reconstruction. It enables us to connectspatially fragmented evidence, relate glacial events to dated climatic changes and consi-der the phasing of glacial events. Substantial effort has gone into establishing a chro-nology of the last British-Irish Ice Sheet (BIIS) (e.g. Andersen, 1981; Ballantyne, 2010;Bowen et al., 2002; Chiverrell and Thomas, 2010). Yet for a long time the chronologyhas been insufficient for assessing phasing with other ice sheets such as the Laurentideand Scandinavian, or the timing of regional/global climate signals such as HeinrichEvents. For example, until very recently, the extent at the Last Glacial Maximum (LGM)was constrained by only five dates (Bowen et al., 2002). Often, and probably for goodreasons such as cost and time, much geochronological work has been conducted on alocal scale. The local-regional focus of the majority of work fails to produce a robustpicture of the general form of the ice sheet and the relative timing of different sectors.In the absence of a good spatial density of dates there is a temptation to extrapolate lo-cal interpretations to the whole ice sheet. However, due to the geographic situation ofthe BIIS on the edge of the North Atlantic and its sensitivity to multiple transitions inthe location of the Polar Front, it is probable that different sectors of the multi-domedice sheet operated differently (Scourse et al., 2009; Clark et al., in press). Recent workhas reflected a desire to produce ice sheet scale syntheses (e.g. Clark et al., 2004a; Evanset al., 2005; Bradwell et al., 2008b) but this has been largely pattern-based rather thanon timing. Recent attempts at compiling dating information are welcome contributions,though have thus far focussed on a single time period (e.g. the LGM; Chiverrell andThomas, 2010), dating method (e.g. terrestrial cosmogenic nuclides; Ballantyne, 2010)or data type (e.g. the offshore record of ice-rafted debris; Scourse et al., 2009). A full andinsightful reconstruction of the last BIIS requires a synthesis of all available geochrono-logical information across the whole of the former bed of the ice sheet, and beyond (e.g.Gyllencreutz et al., 2007), to tie point and spatial-pattern evidence, from sediments andgeomorphology, together with data on timing.

This paper presents a database and map of published absolute dates that constrain thetiming of the ice sheet. Our aim was to produce an easily accessible reference databaseof all published chronological evidence along the lines of the BRITICE database andmap of geomorphological evidence (Clark et al., 2004a; Evans et al., 2005). This wasmotivated by the need to combine evidence from spatially distant parts of the ice sheetmargin in order to reconstruct the retreat of the last BIIS (Clark et al., in press). Thetotal volume of information gathered from systematic inspection of the literature (975dates) was found to be reassuringly large. A considerable volume of information hasamassed in the last decade, partially due to the advent of new dating methods such asin situ terrestrial cosmogenic isotope dating and a renewed interest in the last BIIS (e.g.Vincent et al., 2010; Ballantyne, 2010). In addition to reporting here the ‘raw’ summaryof existing information, dates have been interpreted in terms of their significance for ice

sheet glacial history. All ages referred to in this paper are calendar ages unless docu-mented with the suffix 14C yr BP. The database follows a similar and more ambitiousproject to produce isochrones of build-up and deglaciation from a collation of datesand margin positions for all Eurasian ice sheets during the last glacial cycle conductedby the DATED-group at University of Bergen (Gyllencreutz et al., 2007) and the earliercompilation for the Laurentide Ice Sheet by Dyke et al. (2003).

2. Methods

2.1 Data collation

We conducted a thorough (but probably not exhaustive) search of the published lite-rature for dates pertaining to the growth, development and decay of the last BIIS. Re-view articles and previous collations of chronological information were consulted inthe first instance, including the online Oxford Radiocarbon Laboratory Datelist (OxfordRadiocarbon Accelerator Unit, 2008) and review articles (Sissons, 1967; Andersen, 1981;Sutherland, 1984; Jones and Keen, 1993; Bowen, 1999; Knight, 2001; Bowen et al., 2002;Evans et al., 2005). For Ireland the journal archives of Archaeometry (which publishesOxford radiocarbon laboratory results) and Radiocarbon (Cambridge, Dublin, Belfast,Birmingham, SRR) were systematically searched. The search was extended beyond theQuaternary glaciological literature in order to capture a larger number of relevant dates.For example, the online date list of the Council for British Archaeology (CBA) ‘Archaeo-logical Site Index to Radiocarbon Dates for Great Britain and Ireland’ was obtained infull from The Archaeology Data Service (Council for British Archaeology, 2000, (up-dated 2008)). The census date for inclusion of material was 31 October 2009. In pressarticles were included if available to us by this date. The dataset therefore is an updateto that referred to in Greenwood and Clark (2009) for the Irish Ice Sheet which had acensus date of February 2008. A full bibliography for the table is included at the end ofthis paper.

All sites from the continental shelf relating to the ice sheet and thought to be withinthe maximum extent limits portrayed in Sejrup et al. (2005) are included (Figure 1).Dates from beyond the maximum limits are excluded from the main database with theexception of dates on or close to the accepted maximum southern extension of ice acrossEngland and Wales. Offshore dates with implications for the timing of glacial events,such as the flux of ice-rafted detritus (IRD) (e.g. Scourse et al., 2009), are not includedbut instead are presented in Figure 1, together with a summary of the chronology of theadjacent Fennoscandian Ice Sheet.

Figure 1. Summary of distal geochronological information (from beyond maximum limits of the last British-Irish IceSheet). Information derived from a number of sources (Kroon et al., 2000; Auffret et al., 2002; Wilson et al., 2002; Carr,2004; Houmark-Nielsen, 2004; Laban and van der Meer, 2004; Mangerud, 2004). Dashed line marks presently acceptedmaximum extent of ice during the last glacial. This is simplified after Sejrup et al. (2005) and Bradwell et al. (2008b).Only dates that fall within this maximum extent, as defined here, are included in the database in this paper.

Information we report for each date broadly follows that included by Dyke et al. (2003)in their database of radiocarbon dates for the Laurentide Ice Sheet. Location is givenas reported in the original source; either latitude/longitude or national grid referenceas appropriate. For completeness, where only one piece of location information wasreported in the original source this was used to calculate the absent coordinates. Insome cases precise geographic and projected coordinates were unspecified. To obtaincoordinate information the location figure from the particular paper was scanned andgeocorrected to obtain latitude/longitude and national grid reference (see Clark et al.,2004a, for description of the geocorrection procedure). Due to the potential for introdu-cing location errors by this technique, if the site in question was considered a ‘classic’ orone reported in other papers, these references were checked prior, and in preference, toscanning. It is estimated that the error due to misplacement of dated sites is on the orderof 1 km and therefore unlikely to be problematic for reconstruction at the scale of theice sheet. Locations are given as 12 figure UK Ordnance Survey or Irish grid referencesand decimal degrees to three decimal places.

We report all dates and errors (to 1 standard deviation) as given in the original refe-rence. Dates are from a variety of dating methods, but primarily radiocarbon analysis.In the case of radiocarbon dates the original radiocarbon age excluding any correctionfor marine reservoir effect is reported. All radiocarbon dates require calibration to ca-lendar ages before they can be considered alongside absolute dates derived by othermethods (Reimer et al., 2004; 2009; Guilderson et al., 2005). Detailed discussion of thedifferences between the available calibration curves is documented in (van der Plichtet al., 2004). The BIIS retreat pattern chronology presented in Clark et al. (in press) isbased on the database presented here with the Fairbanks 0107 curve and online calcula-tion tool (http://radiocarbon.ldeo.columbia.edu/) used to calibrate all radiocarbon dates(Fairbanks et al., 2005). Use of the Fairbanks calibration curve was largely a pragmaticchoice. An alternative would have been to calibrate using the internationally agreed ca-libration curves INTCAL04 (Reimer et al., 2004) and MARINE04 (Hughen et al., 2004),as appropriate for each date, to the limit of these curves at c. 26 ka BP and continuedwith the Fairbanks curve for the remainder, noting the offset at the point of change.However, it was decided that the advantages of such an approach were outweighed bythe benefits of using the same calibration curve for all dates, thus creating an internallyconsistent database from which to reconstruct the retreat pattern and timing of the lastBIIS. Whilst this manuscript was in review, the INTCAL09 and MARINE09 curves ex-tending back to 50 ka BP were released (Reimer et al., 2009). We therefore updated thedatabase and calibrated ages listed in the Table are derived using the CALIB Radiocar-bon Calibration Program (Version 6.0.2; http://calib.qub.ac.uk/calib/) using INTCAL09and MARINE09 calibration curves as appropriate for each date. The calibrated datestherefore deviate slightly from calibrated ages listed in the database exert in Clark et al.(in press) and in Greenwood and Clark (2009). Twenty-eight dates were unable to becalibrated as they were either out of range of the calibration curve or no error margins

160

were specified. Both calibrated ages and original radiocarbon ages are presented in theaccompanying Table.

Dates from in situ terrestrial cosmogenic nuclide dating are reported assuming zero ero-sion where different estimates are given in the original source, or as per original sourcewhere only one case is given. However, it is acknowledged that this is likely to be anunreasonable assumption in the context of a history of glacial erosion and deposition.Where there are multiple dates at a single location, it is common in cosmogenic exposuredating, though not always preferred, to take the oldest date as the most reliable (Phillipset al., 2008). This considers the possibility of inheritance and/or postglacial shieldingand interprets the oldest date as a minimum limiting age (Heyman et al., 2011). Ho-wever, some studies use a weighted average of the ages especially where ages occurin a cluster (e.g. Everest et al., 2006; Clark et al., 2009a;b). The most appropriate treat-ment of multiple dates from a single site is still under debate so combined/averagedages should be treated with caution especially in consideration of differences arisingdue to various production rate models and significant error margins (e.g. ± 1000 years)(Heyman et al., 2011; Ballantyne, 2010). Each individual sample date is presented in theTable. No ‘recalibration’ of cosmogenic nuclide dates using different production rateestimate models has been conducted (e.g. Balco et al., 2009; Ballantyne, 2010). We re-port cosmogenic exposure ages derived using the production rate estimates and scalingas chosen in the original publication and do not report isotope determinations or asso-ciated sample information necessary to recalculate ages (Dunai and Stuart, 2009; Balcoet al., 2008). We suggest reference to original sources for full details of laboratory calcu-lations and measurements, and strongly recommend recalculating dates using the sameproduction rates and scaling for precise comparisons with new information.

Where available, the following additional information is reproduced from the sourcematerial. Laboratory codes and/or sample numbers or source reference codes are givenwhen listed in original source. Material dated, method of dating, and stratigraphic orsetting information, including elevation, is reported as described in the original source.Interpretation of ice sheet context (see below) is based on this information and thereforeis dependent on the original quality of description/interpretation. Additional pertinentcomments made by the original authors and/or subsequent researchers are also recor-ded, for example, if a date was believed to be unreliable due to contamination. Manyof the dates derived from the CBA date list contain little or no information on the stra-tigraphic position of the sampled material. Most of these dates are from archaeologicalartefacts and bone found in caves, and therefore constrain the approximate date that thecave was occupied. So, although they do not have complete stratigraphical information,where the sites lie within or close to the limit of the glaciated area, they can still provideminimum dates for when an area became deglaciated enough to allow human or ani-mal occupation, and maximum dates for the onset of glacial conditions that preventedsettlement.

161

Journal of Maps, 2011, 156-184 Hughes, A.L.C. et al

During compilation of the database, no discrimination was made on the quality or relia-bility of dates. All dates encountered are reported here; any comments made by authorson the likely reliability of their dates are noted.

2.2 Interpretation

To the compilation of all reported chronological data, we add one element of interpre-tation. The purpose of data compilation was to provide a resource with which we canconstrain ice sheet position in time (see Clark et al., in press). To achieve this, it is neces-sary to take an interpretative step in terms of each date’s context or setting. We assigneach reported date an interpreted ‘ice sheet context’ based on its stratigraphic positionor local setting (c.f. Bryson et al., 1969). Note that no new data or analysis is introdu-ced in assigning a context to dates; we merely use the setting information provided inthe source publication, and as documented in the Table (stratigraphic position/settingand comments columns). The contextual classes into which we organise the dates areas follows:

1. Advance: we recognise two types of stratigraphy that provide information on ti-ming of ice sheet build up. Dated material incorporated within till; ice cover mustpostdate the given age, but is likely close to it, e.g. organics within till deposit. Da-ted material from a unit stratigraphically below a till unit; ice cover must postdatethe given age, e.g. peat underlying till.

2. Retreat: dated material records ice free conditions subsequent to ice cover. Thesite possesses stratigraphic information specifically indicating ice free conditionspostdate ice cover, e.g. dated organic material lies stratigraphically above a till,dated material infilling a kettle hole, or exposure age from within/below limit ofglacial erosion.

3. Ice free: dated material records ice free conditions but its connection to evidenceof ice cover is lacking. The site possesses no stratigraphic information which indi-cates prior ice cover, e.g. animal bones in caves, or organic sediments not explicitlydescribed as overlying a till or subglacial landforms such as drumlins.

4. Margin: retreat, with evidence of immediate proximity to an ice margin, e.g. boul-der from a moraine crest.

5. Exposure time (cumulative): length of exposure at site that does not possess evidenceof glacial erosion, or no setting or ‘stratigraphic’ information has been provided,e.g. sample above glacial erosion limit or trimline. The age may reflect actuallength of time since the site last became exposed, or multiple phases of exposure

162

Journal of Maps, 2011, 156-184 Hughes, A.L.C. et al

and burial beneath non-erosive ice. Applies exclusively to ages derived from insitu cosmogenic isotope analysis.

We take the most conservative approach to contextualising the dates from the strati-graphic details provided in the original source material; if ‘stratigraphic’ position withrespect to ice cover cannot be explicitly demonstrated, the date is assigned one of themore open classes (e.g. ice free). Dates which have been deemed unreliable are assignedas ‘unclassified’; common reasons for their exclusion include contamination of radiocar-bon dates, incomplete resetting of luminescence dates, signal inheritance of cosmogenicsurface exposure dates, or unreasonably large error margins. Where a single date canconstrain more than one event (for example, organic material between two tills), it isgiven two classifications (e.g. advance; retreat). We note that there may be uncertaintyin some classifications because of the lack of stratigraphic information or confidence inan in situ assemblage. For example, dates from bones within caves are classified as icefree, although they may have amassed in a variety of ways (active use of the cave vs.ice/meltwater transport) which may render the ice free date spatially erroneous. Theremay be conflicts between our interpretations and those of subsequent users of the da-tabase due to reinterpretations of the sedimentological and stratigraphic descriptionsmade in the original sources.

3. Database and map

From over 200 papers and the databases examined, 975 dates from a total of 378 loca-tions were found and are enclosed in the database. We present the data in the accom-panying Table and Map. The dataset is downloadable as a .shp and/or .pdf. TheMap shows all dated sites with corresponding site numbers for cross-referencing withthe database; additional .pdf layers illustrate ice sheet context information with label-led calibrated ages. We recommend printing with only one or two layers displayed forclarity.

Included in the database are 626 radiocarbon dates, 260 in situ terrestrial cosmogenicisotope dates, 80 luminescence, and 9 U- and Th-series dates. Largely as a result of thenature of the dating methods currently available to us (all based on exposure or lack the-reof), the majority of absolute dates relate to ice free conditions, i.e. they are minimumdates for ice sheet retreat or maximum dates for ice sheet advance, and thus bracket thetime period that the ice sheet existed in any particular area. Minimum dates for degla-ciation of ice in (and maximum dates for advance of ice over) a particular area are mostcommonly derived from radiocarbon dating of organic sediments overlying (or under-lying) till or moraines. Such dates define a relatively crude bracket for glaciation due

163

Journal of Maps, 2011, 156-184 Hughes, A.L.C. et al

to the lag time involved between ice melt and vegetation succession. In situ terrestrialcosmogenic isotope exposure dating has been used on occasion to date moraine sur-faces and luminescence dating has been attempted for glaciofluvial outwash sedimentsand loess. These dates provide a more direct means of dating specific ice sheet marginpositions but tend to have high associated errors, often of the order of 1000s of years.

Out of the 975 dates, 816 are interpreted for their ice sheet context. Of these, 115 areadvance, 24 are both retreat and advance dates, 150 are retreat, 84 are margin, and 337 areice free. There are 106 exposure time (cumulative) dates. Unclassified dates include thosethat could not be calibrated or are considered unreliable by the original or subsequentauthors (159). It is unsurprising that the majority of dates relate to ice free conditionsand retreat, since an ice sheet will tend to erase or remould pre-existing material ratherthan preserve it. There are, however, a significant number of advance dates which isencouraging for efforts to constrain ice sheet build-up as well as deglaciation. The spa-tial distribution of dates is similarly encouraging and more ‘complete’ than one mighthave imagined. The number and distribution of sites, and the range of ages and icesheet contexts, put us in a significantly better position for interpreting an ice sheet widechronology for the BIIS than has hitherto been possible. The database has already beenused, along with landform data on retreat patterns to reconstruct the demise of the BIIS(Clark et al., in press).

Nonetheless, there are significant gaps in southern Scotland (notably the Southern Upla-nds), the Cheviots, the Dales, Lake District, central Wales, and central Ireland. Many ofthese data gaps lie in mountain areas, perhaps historically reflecting an absence of or-ganic material suitable for radiocarbon dating in such locations, though this disparityis beginning to be overcome through application of cosmogenic exposure techniques(e.g. Ballantyne et al., 2009a). In Ireland, there is predominance of coastal or near coas-tal sites relative to inland locations, which may help efforts to pinpoint a time-windowfor ice sheet retreat back onto present-day land, but hinder attempts to document icesheet retreat more fully back to its final sites of demise. The most notable gaps, ho-wever, remain the marine sectors of the ice sheet with very little information on thetiming and rapidity of ice retreat across the continental shelf and from the North Sea.Our synthesis of geochronological knowledge, particularly the gaps, identifies targetsfor future dating programmes. We recognise there may be omissions and potential er-rors in the database which require revision; we appeal to the community to notify thecorresponding author(s) of any such information, and new information post-dating thecensus for the database. It is anticipated that this database will be maintained and a newversion released alongside an updated BRITICE database that is currently undergoingcompilation.

4. Summary

Overall the number and spread of dates in time and space is impressive. The last 10years has seen a dramatic increase in the number of dates, partly facilitated by the de-velopment and application of new dating techniques such as terrestrial cosmogenic nu-clides and improvements to radiocarbon dating. However, it is evident from the mapthat the geographical spread is uneven. There are both significant gaps and areas ofover-sampling. The Southern Uplands and Scottish-English border region extendingdown into northeast England, and central Wales and central Ireland stand out as thelargest ‘holes’ in the distribution. Upland areas in general are under-sampled. Offshore,the southern North Sea is devoid of dates as are the seas between the Outer Hebridesand Northern Ireland. All of these regions should be targets for future dating campai-gns. Areas that are currently adequately dated, at least from an ice sheet scale view, arethe Irish coastline, the maximum southern limit in England (although recently publi-shed and existing dates from eastern England are in conflict and so this region requirescareful consideration and possible reassessment of existing dates (Clark et al., in press),the Scilly Isles, the southern limit of the Loch Lomond Stadial ice cap, and the westerncoastline of mainland Scotland (especially in the vicinity of the Wester Ross Moraine).This reflects the long established aim of identifying the maximum extent of ice and thehunt for re-advances.

The temporal spread of dates is presented in Figure 2. The greatest frequency of dates isaround 15 ka BP. This reflects the increased likelihood for preservation of dates constrai-ning the margin positions and retreat of the ice. After 45 ka BP there are fewer than 10dates for each 1000 year time interval. The large number of dates older than 56 ka BP re-flects maximum ages for advance and exposure times where there has been insufficienterosion to give a true age for the most recent exposure (e.g. under cold based ice, Stroe-ven et al., 2002; Hättestrand and Stroeven, 2002; Fabel et al., 2002). It is interesting thatthere is near complete overlap of advance and deglacial dates in time. This demons-trates that different sectors of the ice sheet were advancing while other margins wereretreating. We interpret this as support for a model of a dynamic multi-source last BIIS,possibly never in steady-state with climate (Clark et al., in press). It should be restatedthat we made no attempt to assess the quality of dates and that the database content re-flects the existing published literature. In the light of new radiocarbon methods leadingto revisions of previously accepted dates, it would be beneficial if all the dates containedin this database were scrutinised for quality and reliability. It is beyond the scope of ourcollective expertise (and a significant task in its own right) and we call on the datingcommunity to address this, so as to avoid drawing incorrect interpretations.

We hope that the map and database will be a useful piece of reference informationfor the Quaternary community and stimulate new research and continued interest inthe last BIIS, as was experienced following publication of the Glacial Map of Britain

Figure 2. To complement the spatial distribution of dates presented in the map, this frequency histogram shows thetemporal distribution of dates through the last glacial cycle. The final class includes all dates >55 ka BP (exposure dateswith insufficient erosion and maximum bounding dates for ice advance). Dates are calibrated ages. The frequency ofdates in each 1000 year class is coloured by the contextual class. Radiocarbon dates that could not be calibrated areexcluded. Retreat and advance dates overlap. For example, there are dates constraining advance as late as 17 ka BP(followed by a later group of advance dates between 10-14 ka BP) and retreat dates as early as 42 ka BP. We suggest thatthis reflects the geographical spread of dates and asynchronous behaviour of different sectors of the ice sheet (Clarket al., in press). It is interesting that for most of the time (50 to 10 ka BP) there are recorded dates indicative of iceadvances (at least in some sectors) and that this is even so during the global period of ice recession. It is only between15 and 17 ka BP that no such advance dates exist.

(Clark et al., 2004a; Evans et al., 2005). We will periodically update the database andcall upon the community to notify the authors of new information. Updated versionswill be released through the BRITICE webpages (http://www.sheffield.ac.uk/geography/staff/clark_chris/britice.html); please check here for the latest version.

Software

Date information was recorded in Excel worksheets. Where location information wasnot given, maps were scanned and geocorrected in Erdas Imagine and ENVI. Shapefilesand the map were produced using ArcGIS 9.3. Final map was produced using AdobeAcrobat and Illustrator.

Data

The author has supplied data (as an ESRI Shapefile) used in the production of the ac-companying map. This PDF has a ZIP archive embedded within it (see the attachmenttab) containing the data; you will need to save the file and edit the file extension to .ZIP.Whilst the contents of the ZIP file are the sole responsiblity of the author, the journalhas screened them for appropriateness.

The shapefile is of date locations and is accompanied by a PDF of the tabular data.The table is published as supplementary downloadable material as it is too large to fitwithin the constraints of an A4 page. The table is designed to be readable when printedon A3 landscape paper. Site 108 is absent from the shapefile due to insufficient locationinformation in the original source.

Dates relating to the build up and retreat of the last British -Irish Ice Sheet. Version 1.0. Census date: 31 October 2009.

Table of dates relating to the build up and retreat of the last British-Irish Ice Sheet. Version 1.0. Compiled from existing literature with a census date of 31 October 2009.

Full description of compilation and database given in Hughes, A.L.C., Greenwood, S.L., Clark, C.D. 2011. Dating constraints on the last British-Irish Ice Sheet: a map and database. Journal of Maps, v2011, 156-183.

This is version 1.0 of the database as released in the Journal of Maps paper above. Periodic updates will be released via the BRITICE web pages. Please contact authors for updated information.

*Unplotted due to incorrect location information given in source# Grid references for all Woodman et al. (1997) sites (except Edenvale and Killuragh) taken from Hedges et al. (1997a,b: laboratory dates lists for the Woodman et al. samples) since those reported in the Woodman paper give a poor match to the site locations shown on the map figure.§ Radiocarbon ages calibrated using Calib v. 6.0. Age corresponds to mid point of the range. Where more than one range is given the mid point of the range with the highest probability is taken. + Errors for calibrated radiocarbon dates are based on half the range (see §).NB.
