title: Age determination of profile GRN-I

description: The sampling site was in an extensive blanket bog, 16 km south of Céide Fields Visitor Centre, where peat cutting had revealed many pine timbers and also oak timbers. This provided the opportunity to carry out a palaeoecological study that included pollen analysis and dendrochronological investigations. In the study area, the bedrock is Carboniferous sandstone which, to the east of the sampling area, gives way to Carboniferous limestone of the Moy valley. Here there are thick glacial deposits including well-developed drumlin fields, and the land is fertile and bogs are few.Core GRN I was taken where what appeared to be an isolated small pine stump (P2/W1) was present at ca. 58 cm in a turf bank (depth from the cutover surface; the uppermost peat (≥1 m) had been removed by peat cutters). At a lower level and in a drainage channel below the peat face, there were several pine timbers. A pine stump P1/W2) at this level from beside the core was 14C dated; pine stump P2 was also 14C dated. The age/depth model (Clam v. 2.2) for the pollen profile derives from a smooth spline curve (smooth factor = 0.4) fitted to ten 14C dates which includes two pine timber dates. The uppermost peat-derived 14C date, 1170±30 BP (10–8 cm; at least 1 m of peat had been removed by peat cutters), was regarded as unrealistically young and was not used.The pollen profile GRN I spans the interval ca. 5700–1800 BC. The pollen profile indicates that pine grew in the mire from the beginning of the record (5700 BC) to at least 2600 BC ('pine flush' recorded at 2700–2600 BC). This is supported by a Pinus stomatal record and also dendrochronological investigations of pine in the extensive bog at Garrynagran.The dendrochronological investigations enabled two floating chronologies to be constructed spanning the intervals 4530-4350 BC and 3135–2700 BC (fixed by 14C dates from dendro-matched pines). These data, together with the pollen data, serve to emphasise the importance of bog-pine in the region at ca. 3000 BC. Profile GRN I shows a distinct Elm Decline (but little P. lanceolata) that is followed by a Neolithic Landnam (3700–3300 BC). After a long lull in activity, farming impact begins to register again in a substantial way in the early Bronze Age (2300 BC). The macrofossil data provide evidence for mire development including a substantial role for Sphagnum austinii from ca. 2750 BC onwards.LOI and tephra investigations were also carried out. A distinct tephra layer was present (9–4 cm; highest tephra concentration at 6–5 cm; ca. 1450 BC based on age/depth model). The results of the tephra investigations have yet to be published.The research, most of which was carried out as a PhD project by Eneda Jennings (1997), was supported by Forbairt/Eolas (Irish Research Council) and NUIG Postgraduate Fellowship scheme.

title: (Table 2) Luminescence age determination of sediment profiles from outcrops in the Pechora Basin

description: List of luminescence age-estimates. Samples prefixed by R were dated by the Nordic Laboratory for Luminescence Dating, Riso, Denmark using the coarse-grained (sand) method. For sample treatment see Aitken (1985). Dose rates (in Gy kal) were calculated for each sample after measuring beta activity in the laboratory. Measurements were carried out on both feldspar (F) and quartz (Q) due to differences in internal uranium and thoriurn contribution for the two minerals (a value of 0.1 Gy/ka for quartz and 0.18 Gy/ka for feldspar has been used) (Mejdahl, unpublished). For feldspar, equivalent dose, Dp, has been obtained using the plateau TL method (Mejdahl, 1988), total bleach additive-dose (both IRSL and OSL) and single aliquot regenerated and added dose (SARA) also using both IRSL and OSL (Mejdahl and Botterlensen, 1994). For quartz Dp was obtained using the single aliquot regenerated dose (SARI method (Murray and Roberts, 1998; Murray and Mejdahl, 1998) and partly SARA. The results from measurements on quartz are considered more reliable because quartz does not show anomalous fading (A. Murray, pers. comm.). The 'Age F/Q' column gives a comparison of the F and Q results. The subscripts given after the average values of On are the number of independent estimates included in the average. Datings from unit C, labelled PEC, were made by Quaternary TL Surveys, Nottingham, UK, by measuring luminescence of the fine-grained fraction (Debenham, 1985). These results can be considered maximum ages as the analysis does not account for remnant luminescence, which may yield higher apparent ages, but the datings were reported as minimum ages because instability of the TL signal limits the range of method to 110 ka (N. Debenham, pers. comm.)

title: Age determination of profile CF-IB

description: The short monolith (19 cm of peat and 10 cm of the mineral soil beneath), CF Ib, was taken at 40 m NW of the Visitor Centre (VC), immediately to the north of a transverse stone-wall. Mineral soil from nearby that was sealed by the stone wall also sampled (CF III: 10 cm long monolith).Pollen profile CF I (this has elsewhere been referred to as CF Ib) includes six spectra from the mineral soil and twelve spectra from the overlying peat. Profile CF III consists of six spectra. Four samples from the soil within a plough mark and two samples from the containing soil were pollen analytically investigated. The age/depth model for profile CF I consists of a linear regression line fitted to the three available 14C dates. As regards, profile CF III it is older than the basal peat in CF Ib, i.e. ca. 1000 BC. The pollen data support ascribing it to the Bronze Age. A bulk sample from the plough mark returned the 14C date 2390±40 BP. This suggests a fifth century BC date, i.e. early/mid Iron Age.LOI and tephra investigations were not carried out. These investigations relating to Céide Fields were carried out in PRU, NUIG, part-funded by The Heritage Council (of Ireland). The aim was to provide an environmental context for the establishment and use of the prehistoric stone-wall field system, and an overall chronological framework and an environmental history of the area.

description: A study of organic-walled microfossils from sediment cores of the Central Baltic Sea (North Central Basin, Gotland Basin, Bornholm Basin) and the Kiel Bight was carried out to increase our knowledge of the environmental changes in the Baltic Sea. For this purpose, the absolute abundance of these microfossils were recorded. Quantitative measurements of morphological change of the dinoflagellate Operculodinium centrocarpum, which indicate salinity changes, were performed. The cores from the Central Baltic Sea are correlated ecostratigraphically. The cores from Gotland Basin and Kiel Bight are correlated chronostratigraphically, based on absolute age dating. The first marine influence, indicated by the first occurrence of marine dinoflagellate cysts, and the interval with rapid rising salinity, was dated for Kiel Bight to 8400-7400 yr BP (calendar years), and for the Gotland Basin to 7400-6500 yr BP. The first saline maximum of the early phase of the Littorina Transgression can be found around 6500 yr BP in the Gotland Basin as well as in the Kiel Bight. A significant drop in salinity of the Central Baltic Sea, which was more intense in the northern part, is at 2800 yr BP., whereas a slight increase in salinity took place in the Kiel Bight during this time.

title: (Table 1) Mg/Ca ratios of Cibicidoides pachyderma and age determination of core top sediments from the Florida Straits

description: The recent development of foraminiferal Mg/Ca as a paleotemperature proxy has enabled the extraction of global ice volume and local salinity from the more traditional paleotemperature proxy d18O. The benthic foraminiferal genus Cibicidoides is widely used in paleoceanographic reconstructions because of its epifaunal habitat and cosmopolitan distribution, and it has received early attention in Mg/Ca work. However, existing temperature calibrations for Cibicidoides rely heavily on C. pachyderma core top data from one location, Little Bahamas Bank, where authigenic processes and/or reworking may result in elevated warm water Mg/Ca values. Here we present new C. pachyderma Mg/Ca data from a series of 29 high-quality multicore tops collected in the Florida Straits, spanning a temperature range of 5.8-18.6°C. In contrast to previous calibrations, we find no evidence for a strongly exponential response to temperature. The data are best explained by a linear relationship, with a sensitivity of 0.12 mmol/mol per °C.

description: Oxygen isotope measurements in Greenland ice demonstrate that a series of rapid warm-cold oscillations -called Dansgaard-Oeschger events- punctuated the last glaciation (Dansgard et al., 1993, doi:10.1038/364218a0). Here we present records of sea surface temperature from North Atlantic sediments spanning the past 90 kyr which contain a series of rapid temperature oscillations closely matching those in the ice-core record, confirming predictions that the ocean must bear the imprint of the Dansgaard–Oeschger events (Broecker et al., 1988, doi:10.1016/0033-5894(88)90082-8; 1990, doi:10.1029/PA005i004p00469). Moreover, we show that between 20 and 80 kyr ago, the shifts in ocean-atmosphere temperature are bundled into cooling cycles, lasting on average 10 to 15 kyr, with asymmetrical saw-tooth shapes. Each cycle culminated in an enormous discharge of icebergs into the North Atlantic (a 'Hein-rich event' (Bond et al., 1992, doi:10.1038/360245a0; Broecker et al., 1992, doi:10.1007/BF00193540), followed by an abrupt shift to a warmer climate. These cycles document a previously unrecognized link between ice sheet behaviour and ocean-atmosphere temperature changes. An important question that remains to be resolved is whether the cycles are driven by external factors, such as orbital forcing, or by inter-nal ice-sheet dynamics.

description: Magnetic susceptibility (MS) was measured with high resolution (5 mm) on a 9 m long, 14C dated core from Lake Le Bourget (Savoie, France), spanning the last 7200 years. The strong correlation (R=0.85) of the MS with the silicate-borne suite of elements (Si, Al, Fe, Mg, K) and anti-correlation with the carbonate content (R =-0.87) allows it to be used as a proxy for the fluctuations of the abundance of riverborne clastic fraction versus authigenic carbonates in sediment. As the Rhône is the only river bringing a significant amount of silicate minerals to the coring site, the MS downstream is interpreted as a proxy of the Rhône suspended load discharge in Lake Le Bourget. This is confirmed over the last 3000 years by the good match with the evolution of hydrological activity of the Rhône as it is known through geomorphological studies of well-dated archaeological sites. Over the last 7200 years, the record is consistent with the regional record of lake water-level fluctuations. While the intensity of the MS signal might be widely affected by the human impact on soil stability, the timing of the period of enhanced hydrological activity appears to be mostly climate-related, and should thus constitute a first step toward a high-resolution (&lt; 8 yr) continuous history of hydrological conditions in the NW Alps.
description: Two twin-cores (LDB 0101 and LDB 0102) were taken using an Uwitec® coring device on site I (45044.848'N; 5050.891'E) of the ECCHYMOSE 2001 coring survey. Each synthetic core is composed of a succession of three cores. The second core succession was shifted by 2 m in sediment depth and about 5 m in position, in order to ensure the continuity of the record. Cores were cut into &lt; 2 m sections, split, described and stored at 4°C.

description: Significantly older 14C ages by 2500-7900 years are found for sedimentary total organic carbon (TOC) when compared to ages of codeposited surface-dwelling foraminifera in the southern Okinawa Trough. This age discrepancy increases with rising sea level since the Last Glacial Maximum. A progressive shift in TOC d13C toward more negative values with rising sea level reflects an increasing fractional contribution of terrestrial organics (soil organics, plant debris, and/or fossil organics) to the buried organic pool. Organic matter previously stored on the East China Sea shelf during sea level lowstand and riverine material from Taiwan may be the sources that cause the d13CTOC to shift to more terrestrial values. During the Holocene when sea level is above -40 m, d13CTOC values stabilize within a narrow range (-22.3 to -22.8 per mil) while age discrepancies continue to increase and less chemically weathered sediments are deposited. The increase in age discrepancy between TOC and foraminifera in the Holocene may be due to a wetter climate that drove higher rates of physical weathering on Taiwan and greater transport rates of fossil organic C-bearing lithogenic sediment to the ocean. The climate impact on the relative delivery of fossil and nonfossil TOC in depositional settings influenced by fluvial sources should be considered in interpretations of sedimentary C isotope records.

description: he oxygen minimum zone (OMZ) off Vancouver Island was more oxygen depleted relative to modern conditions during the Allerød (~13.5 to 12.6 calendar kyr) and again from ~11 to 10 kyr. The timing of OMZ intensification is similar to that seen throughout the North Pacific, although the onset appears to have been delayed by ~1500 years off Vancouver Island. Radiocarbon dating of coeval benthic and planktonic foraminifera shows that between 16.0 and 12.6 kyr the age contrast between surface and intermediate waters (920 m depth) off Vancouver Island was similar to, or slightly less than, that today. There is no evidence of an increased age difference (i.e., decreased ventilation) during the deglaciation, particularly during the Allerød. However, sedimentary marine organic carbon concentration and mass accumulation rate increased substantially in the Allerød, suggesting that increased organic matter export was the principal cause of late Pleistocene OMZ intensification off Vancouver Island.
