title: NOAA/WDS Paleoclimatology - Barclay - Prince William Sound - TSME - AK094, PAGES North America 2k Version

description: Living and subfossil trees from glacier forefields are used to develop a 1119-year-long tree-ringwidth chronology. Strong cross-dating among ring-width series from sites up to 60 km apart and an analysis of sample homogeneity support combination of all samples into a single, regional composite chronology. Comparison with instrumental climate data indicates May through July temperatures of the growth year are the primary control on ring-widths. Multidecadal-length warm periods in western Prince William Sound during the past 800 years were centred on AD 1300, 1440 and possibly 1820. Multidecadal-length cool periods were centred on AD 1400, 1660 and 1870. This is the first tree-ring chronology from the Gulf of Alaska region to extend into the first millennium AD.

title: NOAA/WDS Paleoclimatology - Angola-Benguela Front ODP1078C 25KYr Alkenone SST Reconstructions

description: A prominent feature in the Southeast Atlantic is the Angola-Benguela Front (ABF), the convergence between warm tropical and cold subtropical upwelled waters. At present, the sea-surface temperature (SST) gradient across the ABF and its position are influenced by the strength ofsoutheasterly (SE) trade winds. Here, we present a record of changes in the ABF SST gradient over the last 25 kyr.  Variations in this SST contrast indicate that periods of strengthened SE trade-wind intensity occurred during the Last Glacial Maximum, the Younger Dryas, and the Mid to Late Holocene, while Heinrich Event 1, the early part of the Bølling-Allerød, and the Early Holocene were periods of weakened SE trade-winds.

title: NOAA/WDS Paleoclimatology - Spannagel Cave Oxygen Isotope (d18O) Data for the last 10.8ka

description: We present an update (COMNISPA II) of a precisely dated, high-resolution speleothem δ18O record from the Austrian Alps. COMNISPA II consists of five stalagmites from Spannagel Cave, which have comparable δ18O values within periods of simultaneous growth and show similar δ18O variations on centennial to millennial timescales. This allows combining the five stalagmites to one composite record using a newly developed statistical approach. The COMNISPA II stack differs slightly from the previous version, but is better constrained because of additional stalagmites used for the reconstruction and a more objective method used for constructing the composite record. Furthermore, the record now covers the last 11 ka and shows variations in δ18O values by about 2‰. As previously shown, these variations compare well with other records in central Europe and the North Atlantic, and thus reflect a large-scale climate evolution.
description: Continuous stable oxygen isotope record of five speleothems covering nearly the whole Holocene epoch from the high-alpine Spannagel Cave, Central Alps, Austria. The chronology is based on U-Th TIMS dates and the use of a newly developed correlation approach for constructing a composite record (Fohlmeister, 2012, Quaternary Geochronology, Vol. 14, pp. 48 - 56).

title: NOAA/WDS Paleoclimatology - Sauchyn - Whirlpool Point - PIFL - ITRDB CANA330

description: In this paper the mean water year (October through September) flow of the North Saskatchewan River (NSR) at Edmonton, Alberta is reconstructed back to 1063 A.D. using a new network of moisture-sensitive tree-ring chronologies from limber pine and Douglas fir at seven sites in the headwater sub-basins of the North Saskatchewan River Basin (NSRB). Over the full extent of the proxy hydrometric record (1063-2007), we examined 1) the duration and severity of low flow, 2) the dominant frequencies of periodic variability and 3) the correlation between these significant periodicities in proxy streamflow and climate indices, specifically sea surface temperature oscillations, which are known drivers of regional hydroclimatic variability. This new record of the paleohydrology of the NSRB is compared to previous tree-ring reconstructions of the annul flow of the North and South Saskatchewan Rivers. Extending the reference hydrology for the basin from decades to centuries changes perceptions of the reliability of the water supply and understanding of the hydroclimatic variability. The gauge record not does represent the full extent of interannual to multidecadal variability in the tree-ring data; there are periods of low flow in the pre-instrumental record that are longer and more severe than those recorded by the gauge.

title: NOAA/WDS Paleoclimatology - NGRIP and EDML Ice Core 32-11KYrBP Methane Data

description: Reconstructions of past atmospheric methane concentrations are available from ice cores from both Greenland and Antarctica. The difference observed between the two polar methane concentration levels represents a valuable constraint on the geographical location of the methane sources. Here we present new high-resolution methane records from the North Greenland Ice Core Project (NGRIP) and the European Project for Ice Coring in Antarctica (EPICA) Dronning Maud Land (EDML) ice cores covering Termination 1, the Last Glacial Maximum, and parts of the last glacial back to 32,000 years before present. Due to the high resolution of the records, the synchronisation between the ice cores from NGRIP and EDML is considerably improved, and the interpolar concentration difference of methane is determined with unprecedented precision and temporal resolution. Relative to the mean methane concentration, we find a rather stable positive relative interpolar difference throughout the record with its minimum value of 3.7±0.7% between 21,900-21,200 years before present, which is higher than previously estimated in this interval close to the Last Glacial Maximum. This implies that Northern Hemisphere boreal wetland sources were never completely shut off during the peak glacial, as suggested from previous bipolar methane concentration records. Starting at 21,000 years before present, i.e. several millennia prior to the transition into the Holocene, the relative interpolar difference becomes even more positive and stays at a fairly stable level of 6.5±0.8% during Termination 1. We thus find that the boreal and tropical methane sources increased by approximately the same factor during Termination 1. We hypothesise that latitudinal shifts in the Intertropical Convergence Zone (ITCZ) and the monsoon system contribute, either by dislocation of the methane source regions or, in case of the ITCZ, also by changing the relative atmospheric volumes of the Northern and Southern Hemispheres, to the subtle variations in the relative interpolar concentration difference on glacial/interglacial as well as on millennial time scales.

title: NOAA/WDS Paleoclimatology - Palaui Island, Philippines Porites lobata Sr/Ca and d18O data from 1880 to 2012

description: The Pacific Decadal Oscillation (PDO) is a complex aggregate of different atmospheric and oceanographic forcings spanning the extratropical and tropical Pacific. The PDO has widespread climatic and societal impacts, thus understanding the processes contributing to PDO variability is critical. Distinguishing PDO-related variability is particularly challenging in the tropical Pacific due to the dominance of the El Niño-Southern Oscillation (ENSO) and influence of anthropogenic warming signals. Century-long western Pacific records of sub-annual sea surface temperature (SST) and sea surface salinity (SSS), derived from coral Sr/Ca and d18O profiles, respectively, allow for evaluating different climatic sensitivities and identifying PDO-related variability in the region. The summer Sr/Ca-SST record provides evidence of a significant SST increase, likely tied to greenhouse gas emissions. Anthropogenic warming is masked in the winter Sr/Ca-SST record by interannual to multidecadal scale changes driven by the East-Asian Winter Monsoon and the PDO. Decadal climate variability during winter is strongly correlated to the PDO, in agreement with other PDO records in the region. The PDO also exerts influence on the SSS difference between the dry and wet season coral d18O (d18Oc)-SSS records through water advection. The PDO and ENSO constructively combine to enhance/reduce advection of saline Kuroshio waters at our site. Overall, we are able to demonstrate that climate records from a tropical reef environment significantly capture PDO variability and related changes over the period of a century. This implies that the tropical western Pacific is a key site in understanding multifrequency climate variability, including its impact on tropical climate at longer timescales.

title: NOAA/WDS Paleoclimatology - Sugan Lake, China 850 Year Ostracod Geochemical Data

description: The Mg, Sr and Ca contents of single shells of the ostracod Eucypris inflata from sediments retrieved from Sugan Lake, on the northern Tibetan Plateau, were analysed in order to reconstruct the salinity changes during the past ~850 yr. At present, the lake water has a Mg/Ca ratio >40 and carbonates precipitated in the lake in the summer are mainly monohydrocalcites. However, X-ray diffraction analysis of core sediments suggests that several carbonate phases, including aragonite and even possibly dolomite, may have precipitated in the past. During the period (before 1620 AD) when there was aragonite precipitation, the Sr/Ca ratios of ostracod shells were at a minimum and showed little variation. When there was no aragonite precipitation (after 1620 AD), the Sr/Ca ratios of ostracods may have reflected salinity changes. The generally low Mg/Ca ratios during most of the past 850 yr may have resulted from decreased Mg partitioning in high-Mg/Ca host water as ostracods physiologically exclude excess Mg. Therefore, the Mg/Ca of ostracods cannot be used as a salinity proxy. The short-lived Mg/Ca maxima after 1300 AD correspond to decreased Sr/Ca and oxygen isotopes, indicating brief periods of freshwater input. The peaks of Mg/Ca ratios showed a similar variation with temperature change during the past 700 yr, indicating possible temperature dependence during times when the Mg/Ca ratio of the water was reduced. Water chemistry, temperature and mineralogical processes may have all affected the trace-element ratios of ostracods. Combined Sr/Ca ratios, carbonate mineralogy and oxygen isotopes allowed the lake's salinity to be reconstructed during the past ~850 yr. In enclosed lakes in hyper-arid regions, especially in high-Mg/Ca waters, the trace-element chemistry of ostracod shells should be treated with care and the complex controls on trace-element should be examined before paleosalinity or paleotemperature reconstruction is attempted.
description: Ostracod shell oxygen isotope and trace element data from Sugan Lake core SG00C, Qaidam Basin, China. The sediments from this lake are annually laminated: varve counts were undertaken on a parallel core SG00I and correlation between SG00C and GC00I based on bulk carbonate oxygen isotope variations was used to develop a chronology for SG00C. The stable isotope time series was originally described in Holmes et al., (2007) Geophy. Res. Lett. 34, L23403, doi:10.1029/2007GL032228. Note that the carbon isotope data in this dataset were not described in this publication and remain unpublished.
