title: NOAA/WDS Paleoclimatology - D4 - Greenland Positive Matrix Factorization Model Results

description: High-resolution trace element records from polar ice cores are fundamental to identifying spatial and temporal variability in dust and sea salt aerosols. Here, we developed high temporal resolution glaciochemical records over recent centuries from an array of seven recently collected Greenland ice cores. Positive matrix factorization (PMF) was used to assess apportionment of trace elements between three unique sources, which were identified as proxies of carbonate dust, aluminous dust, and sea salt. The three PMF factors agree well with literature values and represent the first time carbonate and aluminous dust sources have been quantifiably differentiated using high-resolution glaciochemistry. The concentrations of all three sources varied with ice core site. However, the large array of ice cores provided a regional-scale understanding of the sources and magnitude of dust and sea salt impurities deposited on the Greenland ice sheet. At the regional level, all three sources varied on seasonal, annual, and multiyear timescales. The seasonal deposition of sea salt impurities reached a maximum in the winter, followed by spring peaks of carbonate and aluminous dust. Over the 331 year composite record, only aluminous dust exhibited a long-term increasing trend that peaked in the 1930s and was followed by a 20% decline in recent decades.

title: NOAA/WDS Paleoclimatology - Woodhouse 2003 Gunnison River Basin Snow Water Equivalent Reconstruction

description: A tree-ring-based reconstruction for 1 April snow water equivalent (SWE) is generated for the Gunnison River basin region in western Colorado. The reconstruction explains 63% of the variance in the instrumental record and extends from 1569 to 1999. When the twentieth-century part of the record is compared to the full record, the variability and extremes in the twentieth century appear representative of the long-term record. However, years of extreme SWE (low and high) and persistent low SWE events are not evenly distributed throughout the record. The twentieth century is notable for several periods that lack extreme years, and along with the nineteenth century and the second half of the eighteenth century, contains many fewer persistent low SWE events than the first half of the reconstruction. Low SWE in the western United States is associated with several circulation patterns, including the Pacific–North American (PNA) pattern and those related to El Niño–Southern Oscillation (ENSO), but the Gunnison River basin is on the edge of the area with a strong relationship to the PNA and is generally in a transitional zone with respect to regional ENSO influences. Tree-ring chronologies from Oregon and New Mexico, regions impacted by ENSO, were used as rough proxies of northwestern and southwestern U.S. winter precipitation to explore possible associations between Gunnison SWE and winter climate in these two regions over the past four centuries.

title: NOAA/WDS Paleoclimatology - Díaz et al. 2002 Chihuahua Winter-Spring Precipitation Reconstruction 1647-1992

description: The state of Chihuahua lies in an arid to semiarid zone in the NW central plain of Mexico. Its agricultural economy is highly vulnerable to frequent droughts. In this study, we reconstruct winter-spring precipitation from 1647-1992 using 6 earlywood width chronologies of Douglas fir from around Chihuahua. The tree-ring data explain 56% of the winter-spring precipitation variance in a linear regression for 1949-1992, and there is strong correlation between the tree-ring reconstructed precipitation data and the observed precipitation data not used for calibration (r = 0.74, p < 0.01). The 5 driest years in the reconstructed precipitation record were 1974, 1954, 1742, 1980, and 1820 in order of severity, and the longest dry period in the 346 yr record lasted about 17 yr (1948-1964) during the severe 1950s drought that also affected the SW United States. The reconstructed precipitation record has a statistically significant 4 yr spectral peak in the El Niño/Southern Oscillation (ENSO) frequency band and is significantly correlated with indices of ENSO (tropical rainfall index; r = 0.58, p = 0.001). The correlation between the ENSO and Chihuahuan reconstructed precipitation varied in strength when computed for non-overlapping 18 yr sub-periods (ranging from r = 0.43 to r = 0.68), which may reflect changes in the ENSO teleconnection to climate in northern Mexico.

title: NOAA/WDS Paleoclimatology - Ellison et al. 2006 8200BP Event Foraminifer Data and Winter/Summer SST Reconstruction

description: Evidence from a North Atlantic deep-sea sediment core reveals that the largest climatic perturbation in our present interglacial, the 8200-year event, is marked by two distinct cooling events in the subpolar North Atlantic at 8490 and 8290 years ago. An associated reduction in deep flow speed provides evidence of a significant change to a major downwelling limb of the Atlantic meridional overturning circulation. The existence of a distinct surface freshening signal during these events strongly suggests that the sequenced surface and deep ocean changes were forced by pulsed meltwater outbursts from a multistep final drainage of the proglacial lakes associated with the decaying Laurentide Ice Sheet margin.

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 - Polar Ice Cores 19th Century Nitrate Data

description: The Carrington Event of 1859 is considered to be among the largest space weather events of the last 150 years. We show that only one out of 14 well-resolved ice core records from Greenland and Antarctica has a nitrate spike dated to 1859. No sharp spikes are observed in the Antarctic cores studied here. In Greenland numerous spikes are observed in the 40 years surrounding 1859, but where other chemistry was measured, all large spikes have the unequivocal signal, including co-located spikes in ammonium, formate, black carbon and vanillic acid, of biomass burning plumes. It seems certain that most spikes in an earlier core, including that claimed for 1859, are also due to biomass burning plumes, and not to solar energetic particle (SEP) events. We conclude that an event as large as the Carrington Event did not leave an observable, widespread imprint in nitrate in polar ice. Nitrate spikes cannot be used to derive the statistics of SEPs.
description: High-resolution 19th Century nitrate data from 7 polar ice cores, examined for evidence of a nitrate spike resulting from the Carrington solar energetic particle event of 1859. Three Antarctic and 4 Greenland ice cores were examined. Biomass burning indicator variables (ammonium, black carbon, and/or vanillic acid) are also reported for some of the Greenland ice cores. These data files would allow the construction of the previously unpublished curves in figures 2-4 of Wolff et al. 2012.

title: NOAA/WDS Paleoclimatology - South China Sea ODP1148 Neogene Benthic Foraminiferal Isotope Data

description: General global cooling over the Neogene has been modulated by changes in Earth's orbital parameters. Investigations of deep-sea sediment sequences show that various orbital cycles can dominate climate records for different latitudes or for different time intervals. However, a comprehensive understanding of astronomical imprints over the entire Neogene has been elusive because of the general absence of long, continuous records extending beyond the Pliocene. We present benthic foraminiferal d18O and d13C records over the past 23 Ma at Ocean Drilling Program Site 1148 in the northern South China Sea and construct an astronomically tuned timescale (TJ08) for these records based on natural gamma radiation and color reflectance data at this site. Our results show that a 41 ka cycle has dominated sediment records at this location over the Neogene, displaying a linear response to orbital forcing. A 100 ka cycle has also been significant. However, it is correlated nonlinearly with Earth's orbital variations at the 100 ka band. The sediment records also display a prominent 405 ka cycle. Although this cycle was coherent with orbital forcing during the Oligocene and the early Miocene, it was not coherent with Earth's orbital variations at the 405 ka band over the whole Neogene. Amplification of Northern Hemisphere and Southern Hemisphere glaciation since the middle Miocene may be responsible for this change in sedimentary response. Our benthic foraminifera d18O and d13C records further exhibit amplitude variations with longer periods of 600, 1000, 1200, and 2400 ka. Apparently, these cycles are nonlinear responses to insolation forcing.
