title: NOAA/WDS Paleoclimatology - Huagapo Cave, Peru 7,200 Year Speleothem Stable Isotope Data

description: Stable oxygen isotope (d18O) measurements of two speleothems, collected from Huagapo Cave in the central Peruvian Andes and with overlapping age from 1.1 to 1.4 ka, characterize tropical South American climate variability over the last 7150 years. In the study region, precipitation d18O (d18Op) is inversely correlated to rainfall amount upstream in the Amazon Basin and the intensity of convection associated with the South American summer monsoon (SASM). Speleothem long-axis profiles yield an average age resolution of five years and permit investigation of climate over orbital to decadal timescales. Variations in the isotopic composition of Huagapo Cave calcite (d18Oc) are in good agreement with several precipitation proxy records from ice cores, speleothems, and lake sediments from the central Peruvian Andes. From the mid-Holocene to today, d18Oc, a proxy for d18Op, tracks changes in local insolation and exhibits a ~2 per mil decrease. In the Late Holocene, Huagapo Cave d18Oc is characterized by two periods of significant decline in SASM intensity (up to 1.5 per mil increase in d18Oc) even when insolation is reaching a local maximum and the SASM would be expected to intensify. These millennial-scale reductions in SASM intensity could in part be influenced by a reduction in the zonal SST gradient of the Pacific Ocean, favoring El Nino-like development.

title: NOAA/WDS Paleoclimatology - Monthly interpolated d18O from Porites lobata coral at Short Drop Off, Republic of Palau from 1993-2003 AD

description: High-resolution measurements of the stable oxygen isotopic signature (d18O) of two new 10-year Porites lobata coral cores and one previously studied multi-decadal sclerosponge Acanthocheatetes wellsi from Republic of Palau (7¼16'N, 134¼31'E) located in the Western Pacific Warm Pool were analyzed and monthly interpolated time-series records developed.  Despite significant differences in collection depth and growth rates, both coral and sclerosponge faithfully recorded the interannual changes of sea surface salinity (SSS) driven by the strong influence of the El Nino Southern Oscillation (ENSO).  The strong relationship of coral skeletal d18O with SSS, but not sea surface temperature or precipitation, confirms previous findings that changes in Palau regional surface water are driven by the advection of water masses into the area over interannual timescales associated with ENSO.  Opportunities exist for the expansion of short coral proxy records with longer sclerosponge records to verify the stability of ENSO-induced SSS variability over longer timescales.

title: NOAA/WDS Paleoclimatology - North Horn Formation, Utah Paleocene-Eocene Thermal Maximum Clumped Isotopes

description: The precipitation of primary dolomite in soil is rare and controversial, and its occurrence indicates highly unusual geochemical and climatic conditions. We utilize isotopic and petrographic techniques, including clumped isotope thermometry, to evaluate diagenetic alteration and preservation of primary climatic signal in dolomitic paleosol nodules from a section spanning the Paleocene-Eocene boundary in central Utah. Isotopic measurements differentiate samples into groups that may be interpreted in terms of alteration; however moderate burial depths and extreme warmth during the interval of soil formation make it difficult to reach definitive conclusions from isotope values alone. With the addition of petrographic analysis, including cathodoluminescence and scanning electron microscopy, we are able to identify textural differences between samples suggesting differing amounts of recrystallization. We conclude that while some nodules have experienced significant diagenetic alteration the original nodule mineralogy is dolomite, and the majority of sampled nodules retain a primary paleoclimate signal. Early Paleogene temperatures recorded at this site are considerably warmer than those suggested for the continental interior from alternate proxies, a result that may be partially the result of the clumped isotope temperatures recording warm season soil temperatures, rather than mean annual air temperature. Soil water isotopic composition is suggestive of heightened aridity, particularly through the Paleocene-Eocene Thermal Maximum (PETM).

title: NOAA/WDS Paleoclimatology - Arabian Sea Geochemical and Sedimentological Data from Core SO130-289KL tor the Last 80 kyr

description: The Dansgaard-Oeschger oscillations and Heinrich events described in North Atlantic sediments and Greenland ice are expressed in the climate of the tropics, for example, as documented in Arabian Sea sediments. Given the strength of this teleconnection, we seek to reconstruct its range of environmental impacts. We present geochemical and sedimentological data from core SO130-289KL from the Indus submarine slope spanning the last ~ 80 kyr. Elemental and grain size analyses consistently indicate that interstadials are characterized by an increased contribution of fluvial suspension from the Indus River. In contrast, stadials are characterized by an increased contribution of aeolian dust from the Arabian Peninsula. Decadal-scale shifts at climate transitions, such as onsets of interstadials, were coeval with changes in productivity-related proxies. Heinrich events stand out as especially dry and dusty events, indicating a dramatically weakened Indian summer monsoon, potentially ! increased winter monsoon circulation, and increased aridity on the Arabian Peninsula. This finding is consistent with other paleoclimate evidence for continental aridity in the northern tropics during these events. Our results strengthen the evidence that circum-North Atlantic temperature variations translate to hydrological shifts in the tropics, with major impacts on regional environmental conditions such as rainfall, river discharge, aeolian dust transport, and ocean margin anoxia.
description: This data set contains elemental analyses (Si, Ti, Al, Fe, Mg, Ca, K, Ni, Zr), total organic carbon (TOC) measurements, grain-size analyses and a Lamination Index record of sediment core SO130-289KL. The elemental analyses were accomplished with X-ray fluorescence (XRF) using Philips PW 2400 and PW 1480 wavelength dispersive spectrometers TOC was acquired with a LECO CS-444 instrument. Grain size analyses were performed on a laser diffraction particle size analyzer (Beckman Coulter) LS200. The Lamination Index was determined visually on sediment cores.

title: NOAA/WDS Paleoclimatology - Colenutt - Grays Creek Pass Recollection - LALY - CANA308, PAGES North America 2K Version

description: In western North America, snowpack has declined in recent decades, and further losses are projected through the 21st century. Here, we evaluate the uniqueness of recent declines using snowpack reconstructions from 66 tree-ring chronologies in key runoff-generating areas of the Colorado, Columbia, and Missouri River drainages. Over the past millennium, late 20th century snowpack reductions are almost unprecedented in magnitude across the northern Rocky Mountains and in their north-south synchrony across the cordillera. Both the snowpack declines and their synchrony result from unparalleled springtime warming that is due to positive reinforcement of the anthropogenic warming by decadal variability. The increasing role of warming on large-scale snowpack variability and trends foreshadows fundamental impacts on streamflow and water supplies across the western United States.

description: Spatiotemporal variations in tree growth are induced by varying environmental conditions. Different methods like variants of the principal component analysis and the hierarchical cluster analysis are commonly applied in dendroecology to separate subsets of growth patterns within large tree-ring datasets. To seek for methodological differences in classification techniques and their specific characteristics, we compared three standard methods using a homogeneous oak (Quercus spp.) network from temperate forests in Central-West Germany. Classifications of the original dataset consisting of 46 oak ring-width sites, carried out with the varimax rotated principle component analysis, Ward's method and the average linkage method, reveal differences in the classification of approximately 20% of the sites. Analyses with modified datasets are calculated to evaluate effects of dataset extension, different time periods and different tree-ring detrendings. The application of the principal component analysis generally leads to the most stable site classifications, whereas the most sensitive response to changes in the dataset is obtained by Ward's method. The average linkage method separates single sites in the classification and thus emphasises outliers within the tree-ring network.
