title: NOAA/WDS Paleoclimatology - Bougainville Guyot - 350 KYrBP Fossil Coral Sr/Ca, Mg/Ca, and Stable Isotope Data

description: The nature of tropical climate variability ~350 ka is addressed using d18O and Sr/Ca records from a modern and a fossil coral from Vanuatu (southwestern tropical Pacific Ocean). Modern El Niņo events at Vanuatu produce positive coral d18O and Sr/Ca anomalies; similar anomalies observed in the fossil coral records suggest that El Niņo was operative 350 kyr ago. Seasonal variations in coral Sr/Ca, a sea surface temperature (SST) proxy, have the same amplitude in both corals, whereas seasonal d18O variations are smaller in the fossil coral than in the modern coral. This is consistent with displacement of the South Pacific Convergence Zone toward the southwest during the boreal summer ~350 ka. Mathematical modeling results preclude warmer SST and higher SSS at Vanuatu during this time, but permit the surface ocean to be ~2°C cooler and 0ŋ2 psu fresher than today. Assessing the potential of variations in late Quaternary seawater Sr/Ca remains the largest obstacle to accurately reconstructing tropical SST using pristine fossil corals.
description: Analyses of stable isotopes (Delta 18O, Delta 13C) and elemental ratios (Sr/Ca, Mg/Ca in mmol/mol) of a 335-374 ka fossil Porites sp. coral obtained on ODP leg 134, sample 831B-18R-1, 110-125. The approximately 14 years of data were used to investigate salinity and temperature variations in that region as they relate to South Pacific Convergence Zone activity and ENSO.  Core ODP831B, Bougainville Guyot, Republic of Vanuatu: 16 00.56'S, 166 40.34E, water depth 1066m. BG831: Fossil coral sample from ODP site 831B, depth in core 238.3 mbsf.  Porites sp. sample is from ODP leg 134, site 831B, sample number 831B-18R-1, 110-125. The isotope data were analyzed at the University of South Florida College of Marine Science, on a Finnigan Delta Plus XL mass spectrometer and attached Kiel Carbonate Device with an analytical precision of 0.04‰ for carbon and 0.08‰ for oxygen (1 sigma) determined by repeated measurements of NBS 19 relative to VPDB. The elemental data were analyzed on a Perkin Elmer Optima 4300DV ICP-OES following the drift-correction methods of Schrag (1999). Analytical precision for the Sr/Ca determinations is 0.15 % RSD (0.013 mmol/mol), based on a laboratory standard solution of dissolved Porites lutea. Depth series were converted to time series and re-sampled to 12/year using AnalySeries software (Paillard et al., 1996) to match the modern average annual SST cycle with Sr/Ca cycles.

title: NOAA/WDS Paleoclimatology - Northern Caribbean Stalagmite Stable Isotope Data during the Last Deglaciation

description: Marking the transition between the last glacial and Holocene, the last deglaciation featured rapid climate shifts including Heinrich event 1 and the Bølling–Allerød. This study presents the highest-resolution, continuous hydroclimate proxy records of this interval from the tropical Americas based on a precisely dated Cuban stalagmite. The records span 17.6–14.3 thousand years before present, revealing persistent interannual to multidecadal rainfall variability, attributed to El Niño-Southern Oscillation and Atlantic Multidecadal Variability. Broader centennial to millennial-scale trends are linked to major climate events. We observe peak aridity in western Cuba during Heinrich event 1.1 and 1.2 (~16.2 and ~15.1 thousand years before present), with preceding dry periods within chronological uncertainty, suggesting synchronicity. Wetter conditions and increased growth rates follow during the Bølling–Allerød. Model-based rainfall estimates support these results. Our proxy data highlight the dynamic nature of tropical hydroclimate, demonstrating wet and dry conditions fluctuate across timescales, despite climate state.

title: NOAA/WDS Paleoclimatology - Gardener's Gut, Max's Cave, Ruakuri Cave Geochemical Data from 11800 to -23 Cal Yr BP

description: The stable isotope records of four stalagmites dated by 19 TIMS uranium series ages are combined to produce master chronologies for δ 18O and δ 13C. The δ 18O records display good overall coherence, but considerable variation in detail. Variability in the δ 13C records is greater, but general trends can still be dis cerned. This implies that too fine an interpretation of the structure of individual isotopic records can be unreliable. Speleothem δ 18O values are demonstrated to show a positive relationship with temperature by comparing trends with other proxy records, but also to respond negatively to rainfall amount. Speleothem δ 13C is con sidered to be most influenced by rainfall. The postglacial thermal optimum occurred around 10.8 ka BP, which is similar in timing to Antarctica but up to 2000 years earlier than most Northern Hemisphere sites. Increasingly negative δ 18O values after 7.5 ka BP indicate that temperatures declined to a late mid-Holocene minimum centred around 3 ka BP, but more positive values followed to mark a warm peak about 750 years ago which coincided with the ‘Mediaeval Warm Period’ of Europe. Low δ 18O values at 325 years BP suggest cooling coincident with the ‘Little Ice Age’. A marked feature of the δ13C record is an asymmetric periodicity averaging c. 2250 years and amplitude of c. 1.9‰. It is concluded that this is mainly driven by waterbalance variations with negative swings representing particularly wet intervals. The δ18O record shows a higher-frequency cyclicity with a period of c. 500 years and an amplitude of c. 0.25‰. This is most likely to be temperature-driven, but some swings may have been amplified by precipitation.
description: Data contributed as part of SISAL v3 Global Speleothem Isotope and Trace Element Database (https://doi.org/10.25921/jajq-qg60). Notes from the SISAL database: Vegetation and land use: Podocarp-hardwood evergreen forest formerly covered the area but much has been cleared in the last 100 years. \\ Elevations between 60-120m altitude are given in publications for speleothems in site_id=163. Entity GG1 (SISAL entity_id = 357) and GG2 (entity_id = 358) do not have age models in original publication. This update is based on COPRA (Breitenbach et al., 2012) using a PCH spline. GG1 (entity_id = 357): The basal TIMS date (9104 ka) has a large error because of detrital thorium and so is statistically indistinguishable from the next youngest date (9163 ka), which has a small 2-sigma error. In order to avoid an apparent age reversal, the basal date was therefore assigned a value of 9721 ka.

title: NOAA/WDS Paleoclimatology - Woodhouse et al. 2006 Updated Streamflow Reconstructions for the Upper Colorado River Basin

description: Updated proxy reconstructions of water year (October-September) streamflow for four key gauges in the Upper Colorado River Basin were generated using an expanded tree ring network and longer calibration records than in previous efforts. Reconstructed gauges include the Green River at Green River, Utah; Colorado near Cisco, Utah; San Juan near Bluff, Utah; and Colorado at Lees Ferry, Arizona. The reconstructions explain 72-81% of the variance in the gauge records, and results are robust across several reconstruction approaches. Time series plots as well as results of cross-spectral analysis indicate strong spatial coherence in runoff variations across the subbasins. The Lees Ferry reconstruction suggests a higher long-term mean than previous reconstructions but strongly supports earlier findings that Colorado River allocations were based on one of the wettest periods in the past 5 centuries and that droughts more severe than any 20th to 21st century event occurred in the past.
description: Updated Streamflow Reconstructions for the Upper Colorado River Basin, based on a network of moisture-sensitive tree-ring chronologies in Colorado, southwestern Wyoming, and northeastern Utah. Tree-ring base reconstructions were generated for a set of 10 gages in the Upper Colorado River basin including Lees Ferry, as well as gages in the Green, Gunnison, Colorado main stem, and San Juan River basins. Reconstructions were generated using several reconstruction methods to test the robustness of results to different statistical approaches. All the gages but Lees Ferry were generated using both a full set of predictor chronologies and a geographically limited (upstream watershed + 100km buffer) set with stepwise regression. Four different approaches were used for Lees Ferry; residual chronologies in stepwise regression (Lees-A), standard chronologies in stepwise regression (Lees-B), principal components regression with residual chronologies (Lees-C), and principal components regression with standard chronologies (Lees-D). Units are millions of cubic meters. Details on methodology are in Woodhouse et al. 2006. The natural flow estimates for the gage data, 1906-1995, used for the calibrations were provided by Jim Prairie of the U.S. Bureau of Reclamation in the summer of 2005. Units are in millions of cubic meters. 1. Full Pool Reconstructions for 9 gage locations; 2. Geographically-Limited Pool Reconstructions for 9 gage locations; 3.

title: MassIVE MSV000098565 - MicroRNA-21 deficiency exacerbates amyloid pathology and memory impairment by disrupting postsynaptic signaling
title: Growing evidence suggests that the dysregulation of microRNAs (miRs) contributes to the pathogenesis of various neurodegenerative diseases, including Alzheimer's disease (AD). Although previous studies have implicated miR-21 as potential biomarker for AD, its functional role remains unclear. To investigate miR-21 function in the context of amyloid pathology, we generated miR-21 deficient amyloid-beta (Abeta) amyloidosis mouse model. Here, we demonstrate that the deletion of miR-21 increases the levels of both insoluble and soluble Abeta, and exacerbates amyloid plaque deposition and gliosis. Mechanistic studies indicate that miR-21 deficiency increases the protein level of its target gene, RECK, thereby inhibiting ADAM10 activity. Consequently, loss of ADAM10 activity decreases soluble amyloid precursor protein-alpha (sAPPa) levels. Furthermore, miR-21 deficiency impairs memory by decrease postsynaptic proteins, PSD95 and HOMER1. Taken together, our findings establish the critical role of miR-21 in an amyloid mouse model and suggest that modulating the levels or activity of miR-21 may represent a therapeutic strategy for AD.
