title: NOAA/WDS Paleoclimatology - Indo-Pacific Warm Pool Last Glacial Maximum Hydroclimate Proxy Synthesis

description: The Indo-Pacific warm pool - the main source of heat and moisture to the global atmosphere - plays a prominent role in tropical and global climate variability. During the Last Glacial Maximum, temperatures within the warm pool were cooler than today and precipitation patterns were altered, but the mechanism responsible for these shifts remains unclear. Here we use a synthesis of proxy reconstructions of warm pool hydrology and a multi-model ensemble of climate simulations to assess the drivers of these changes. The proxy data suggest drier conditions throughout the centre of the warm pool and wetter conditions in the western Indian and Pacific oceans. Only one model out of twelve simulates a pattern of hydroclimate change similar to our reconstructions, as measured by the Cohen's K statistic. Exposure of the Sunda Shelf by lower glacial sea level plays a key role in the hydrologic pattern simulated by this model, which results from changes in the Walker circulation driven by weakened convection over the warm pool. We therefore conclude that on glacial-interglacial timescales, the growth and decay of ice sheets exert a first-order influence on tropical climate through the associated changes in global sea level.
description: Synthesis of hydroclimatic proxy records for the Indo-Pacific Warm Pool at the Last Glacial Maximum, indicating wet or dry hydroclimatic conditions from both marine and terrestrial proxies. The files "terr_raw" and "marine_raw" contain the locations and hydroclimate state at the LGM from a collection of proxy records. Their "val" field indicates whether the proxy captured dry(val=-1)/unchanged(val=0)/wetter(val=1) or fresh(val=-1)/unchanged(val=0)/salty(val=1) climate at the LGM. The "n_obs" field is the number of proxy techniques used to estimate LGM hydroclimate from each location. A value "is_robust=1" indicates when different proxy techniques agree in their estimates of LGM hydroclimate at each location. The "is_robust" field also takes the value of 1 when only one proxy technique is used. A value "chrono_flag=1" indicates whether the proxy record contains one or more radiocarbon U/Th or well-constrained OSL dates near to or during the LGM. A value "chrono_flag=0" indicates that the LGM was dated via wiggle-matching the local benthic d18O to a global stack or another method. The files "terr_gridded" and "marine_gridded" are the final "gridded" data as seen in the main text of DiNezio and Tierney (2013), in which proxies were averaged within a search radius of 150 km. The "is_robust" field of "terr_gridded" and "marine_gridded" indicates whether the observations merged into each "gridded" point agree (is_robust=1) or not (is_robust=0). See DiNezio and Tierney (2013) for more details.

title: NOAA/WDS Paleoclimatology - Kaiser - Daettnau 3 Late Glacial Subfossil - PISY - ITRDB SWIT197

description: Lateglacial and Holocene tree-ring chronologies are unique archives, which provide various information on past environments on a true annual time scale. Changes in ring-width can be related to past climate anomalies and dendrodated wood provides an ideal source for radiocarbon calibration. We present a 1051 year tree-ring chronology from the Late Glacial, built from subfossil Scots pines (Pinus sylvestris) that grew in different regions of Central and Southern Europe. Through a series of high-precision radiocarbon measurements we obtained a floating radiocarbon chronology, which allowed accurate wiggle-matching to the INTCAL98 calibration curve. The trees show a coherent pattern in ring-width variations throughout Central Europe, and extending into the Mediterranean, which indicates a strong external climatic factor, most probably temperature during the growing season. We identified major growth events, which appear synchronous with events seen in isotopic and tracer signals in the Greenland ice cores and with changes in the strength of upwelling in the Cariaco Basin.

description: The Asian monsoon system affects more than half of humanity worldwide, yet the dynamical processes that govern its complex spatiotemporal variability are not sufficiently understood to model and predict its behavior, due in part to inadequate long-term climate observations. Here we present the Monsoon Asia Drought Atlas (MADA), a seasonally resolved gridded spatial reconstruction of Asian monsoon drought and pluvials over the past millennium, derived from a network of tree-ring chronologies. MADA provides the spatiotemporal details of known historic monsoon failures and reveals the occurrence, severity, and fingerprint of previously unknown monsoon megadroughts and their close linkages to large-scale patterns of tropical Indo-Pacific sea surface temperatures. MADA thus provides a long-term context for recent monsoon variability that is critically needed for climate modeling, prediction, and attribution.

title: NOAA/WDS Paleoclimatology - Lough-na-Shade, Ireland 1000Yr Ostracode Stable Isotope Data

description: A 1000 year long subdecadal-resolution record of carbonate oxygen isotopes (d18Oc) from Lough-na-Shade, Ireland, provides evidence for changing atmospheric circulation over northwest Europe. The total range of d18Oc values (>5‰) is too large to be explained by changes in water temperature. Moreover, good correlation between the lake record and a previously published d18O time series from an Irish speleothem indicates that the changes in oxygen isotopes are best explained by variations in the isotopic composition of precipitation. The amplitude of change during this period is too large to be explained by shifts in condensation temperature. Instead we suggest that there have been changes in vapour source and transport paths connected with shifts in atmospheric circulation. Changes from a source area from further south within the North Atlantic to one further to the north could explain the prominent positive shift in oxygen-isotope values between the early eighteenth and early nineteenth centuries, for example. Our results also demonstrate the value of a 'multiple-archive' approach to deconvolving lake-based carbonate isotope profiles, which are often complex.

title: NOAA/WDS Paleoclimatology - Pigmy Basin MD02-2553 Holocene Mineralogical and Geochemical Data

description: Changes in terrigenous-transfer patterns from North America toward the Gulf of Mexico via the Mississippi River during the Holocene were investigated using mineralogical and geochemical records from the northern Gulf of Mexico (Pigmy Basin). Clay mineralogy (smectite/illite+chlorite) and geochemical signatures (K and Ti intensities) indicate fluctuations in the detrital sedimentation during the Holocene in the Pigmy Basin. They likely reflect alternations between at least two dominant terrigenous sources: the smectite-rich NW Mississippi watershed, and the illite- and chlorite-rich Great Lakes province and NE Mississippi watershed. These recurring and rapid modifications of erosional processes over this period suggest changes in the hydrological regime via rainfall patterns. Such a modification during the Holocene is likely linked with the rapid atmospheric reorganization following the final collapse of the Laurentide Ice Sheet. Indeed, mineralogical and geochemical proxies indicate east-to-west migrations of the main detrital source (from the Great Lakes and north-eastern province toward the north-western province) associated with Mississippi River megaflood episodes. These modifications of the main detrital sources likely record migrations of the precipitation belt, which are constrained by atmospheric configuration (Jet Stream, Bermuda High and Intertropical Convergence Zone position) and subtropical oceanic hydrological properties (meridional extension of the Atlantic Warm Pool). In the frame of previously published rainfall patterns over the Caribbean and North America, our results highlight some marked modifications of moisture transfer throughout the Holocene. These changes are interpreted as resulting from two atmospheric configurations that have driven alternately the precipitation distribution over North America for the last 10 ka with an apparent cyclicity of ~2.5 ka. The coherent common cyclicity between Gulf of Mexico detrital parameters and Greenland atmospheric proxies over the Holocene suggests that the initial external forcing was rapidly transferred latitudinally through atmospheric processes.

title: NOAA/WDS Paleoclimatology - Esper - Boibar Valley 3 - JUSP - ITRDB PAKI011

description: We present an analysis of 28 juniper tree-ring sites sampled over the last decades by several research teams in the Tien Shan and Karakorum mountains of western central Asia. Ring-width chronologies were developed on a site-by-site basis, using a detrending technique designed to retain low-frequency climate variations. Site chronologies were grouped according to their distance from the upper timberline in the Tien Shan (~3,400 m a.s.l.) and Karakorum (~4,000 m), and low- and high-elevation composite chronologies combining data from both mountain systems developed. Comparison of these elevational subsets revealed significant coherence (r = 0.72) over the 1438–1995 common period, which is inconsistent with the concept of differing environmental signals captured in tree-ring data along elevational gradients. It is hypothesized that the uniform growth behavior in central Asian juniper trees has been forced by solar radiation variations controlled via cloud cover changes, but verification of this assumption requires further fieldwork. The high-elevation composite chronology was further compared with existing temperature reconstructions from the Karakorum and Tien Shan, and long-term trend differences discussed. We concluded that the extent of warmth during medieval times cannot be precisely estimated based on ring-width data currently available.

title: NOAA/WDS Paleoclimatology - Gardar Drift JPC-13 128KYr Multiproxy Sediment Data

description: We report stable isotope, core scanning XRF, and ice-rafted detritus (IRD) data in glacial-aged sediments from piston Core KN166-14-JPC-13 (hereafter referred to as JPC-13) retrieved at 53.1°N 33.5°W on the southern Gardar Drift, North Atlantic. A chronology was established by correlating millennial-scale features in the benthic d18O record to Portuguese Margin Core MD95-2042. Once the alignment of benthic d18O of JPC-13 to MD95-2042 is fixed, the relative timing of proxy variables is used to determine the phasing of changes in IRD and surface-deep hydrography. Each peak in North Atlantic IRD coincided with a decrease in benthic d18O that, in turn, has been linked to warming in Antarctica (Events A1-A7). The IRD pulses are followed shortly thereafter by abrupt decreases in planktonic d18O, indicating warming and increased heat transport to the subpolar North Atlantic associated with Greenland interstadials (GIS) 8, 12, 14, and 16-17. Grain-size and elemental (K/Ti) variations indicate that Iceland-Scotland Overflow Water (ISOW) was stronger during these long, warm interstadial periods of Marine Isotope Stage (MIS) 3. The results are consistent with interhemispheric phase relationships inferred from Iberian Margin sediment cores and with methane synchronization of Greenland and Antarctic ice cores.

title: NOAA/WDS Paleoclimatology - Barrett fire data from Hudson Lake - IMPD USHUD001

description: Although recent climatic warming has markedly increased fire activity in many biomes, this trend is spatially heterogeneous. Understanding the patterns and controls of this heterogeneity is important for anticipating future fire-regime shifts at regional scales and for developing land-management policies. To assess climatic and land-cover controls on boreal-forest fire regimes, we conducted macroscopic-charcoal analysis of sediment cores and GIS analysis of landscape variation in south-central Alaska. Results reveal that fire occurrence was highly variable both spatially and temporally over the past seven millennia. At two of four sites, the lack of distinct charcoal peaks throughout much of this period suggests the absence of large local fires, attributed to abundant water bodies in the surrounding landscape that have likely functioned as firebreaks to limit fire spread. In contrast, distinct charcoal peaks suggest numerous local fires at the other two sites where water bodies are less abundant. In periods of the records where robust charcoal peaks allow identification of local fire events over the past 7000 years, fire return intervals varied widely with a range of 138-453 years. Furthermore, the temporal trajectories of local-fire frequency differed greatly among sites and were statistically independent. Inferred biomass burning and mean summer temperature in the region were not significantly correlated prior to 3000 years ago, but became positively related subsequently with varying correlation strengths (r = 0.40-0.66; p = 0.001-0.040 for 2000-yr moving windows). Climatic variability associated with the Medieval Climate Anomaly and the Little Ice Age, along with the expansion of flammable Picea mariana forests, probably have heightened the sensitivity of forest burning to summer-temperature variations over the past three millennia. These results elucidate the patterns and controls of boreal fire-regime dynamics over a broad range of spatiotemporal scales, and imply that anthropogenic climatic warming and associated land-cover changes, in particular lake drying, will interact to affect boreal-forest burning over the coming decades.

title: NOAA/WDS Paleoclimatology - Central Arctic Ocean 150KYr Amino Acid Racemization Data

description: The long-term rate of racemization for amino acids preserved in planktonic foraminifera was determined by using independently dated sediment cores from the Arctic Ocean. The racemization rates for aspartic acid (Asp) and glutamic acid (Glu) in the common taxon, Neogloboquadrina pachyderma, were calibrated for the last 150 ka using 14C ages and the emerging Quaternary chronostratigraphy of Arctic Ocean sediments. An analysis of errors indicates realistic age uncertainties of about ±12% for Asp and ±17% for Glu. Fifty individual tests are sufficient to analyze multiple subsamples, identify outliers, and derive robust sample mean values. The new age equation can be applied to verify and refine age models for sediment cores elsewhere in the Arctic Ocean, a critical region for understanding the dynamics of global climate change.
