title: NOAA/WDS Paleoclimatology - Sydney Basin, Australia Permian-Triassic Boundary Geochemical Data

description: Past studies of the end-Permian extinction (EPE), the largest biotic crisis of the Phanerozoic, have not resolved the timing of events in southern high-latitudes. Here we use palynology coupled with high-precision CA-ID-TIMS dating of euhedral zircons from continental sequences of the Sydney Basin, Australia, to show that the collapse of the austral Permian Glossopteris flora occurred prior to 252.3 Ma (~370 kyrs before the main marine extinction). Weathering proxies indicate that floristic changes occurred during a brief climate perturbation in a regional alluvial landscape that otherwise experienced insubstantial change in fluvial style, insignificant reorganization of the depositional surface, and no abrupt aridification. Palaeoclimate modelling suggests a moderate shift to warmer summer temperatures and amplified seasonality in temperature across the EPE, and warmer and wetter conditions for all seasons into the Early Triassic. The terrestrial EPE and a succeeding peak in Ni concentration in the Sydney Basin correlate, respectively, to the onset of the primary extrusive and intrusive phases of the Siberian Traps Large Igneous Province.

title: NOAA/WDS Paleoclimatology - Pederson - Montgomery Place - QURU - ITRDB NY032

description: Six water emergencies have occurred since 1981 for the New York City region (NYC) despite: 1) its perhumid climate, 2) substantial conservation of water since 1979 and 3) meteorological data showing little severe or extreme drought since 1970. We reconstruct 472 years of moisture availability for the NYC watershed to place these emergencies in long-term hydroclimatic context. Using nested reconstruction techniques, 32 tree-ring chronologies comprised of 12 species account for up to 66.2% of the average May-August Palmer Drought Severity Index. Verification statistics indicate good statistical skill from 1531-2003. The use of multiple tree species, including rarely-used species that can sometimes occur on mesic sites like Liriodendron tulipifera, Betula lenta and Carya spp., seems to aid reconstruction skill. Importantly, the reconstruction captures pluvial events in the instrumental record nearly as well as drought events and is significantly correlated to precipitation over much of the northeastern US. While the mid-1960s drought is a severe drought in the context of the new reconstruction, the region experienced repeated droughts of similar intensity, but greater duration during the 16th and 17th centuries. The full record reveals a trend towards more pluvial conditions since ca 1800 that is accentuated by an unprecedented, 43-year pluvial event that continues through 2011. In the context of the current pluvial, decreasing water usage, but increasing extra-urban pressures, it appears that the water supply system for the greater NYC region could be severely stressed if the current water boom shifts towards hydroclimatic regimes like the 16th and 17th centuries.

title: NOAA/WDS Paleoclimatology - North Atlantic DSDP545 Mid-Cretaceous Biomarker SST and Carbon Model Data

description: Most of the marine biotic crises that occurred during the hot Mesozoic era have been linked to episodes of extreme warmth. Others, however, may have occurred during cooler intervals that interrupted Cretaceous greenhouse warmth. There are some indications of cooling in the late Aptian (116-114 Myr ago), but it has not been definitively linked to biotic crisis. Here we assess the timing and magnitude of late Aptian cooling and its association with biotic crises using a suite of geochemical and micropalaeontological assessments from a marine sediment core from the North Atlantic Ocean as well as global biogeochemical modelling. Sea surface temperatures derived from the TEX86 proxy suggest that surface waters cooled by about 5°C during the two million years, coincident with a positive d13C excursion of approximately 2 per mil in carbonates and organic carbon. Surface productivity was enhanced during this period, but the abundance of planktonic foraminifera and nannoconid phytoplankton declined. Our simulations with a biogeochemical model indicate that the d13C excursion associated with the cooling could be explained by the burial of about 812,000 gigatons of carbon over 2.5 million years. About 50% of the this carbon burial occurred in the Atlantic, Southern and Tethys ocean basins. We conclude that global cooling during greenhouse conditions can cause perturbations to marine ecosystems and biogeochemical cycles at scales comparable to those associated with global warming.

title: NOAA/WDS Paleoclimatology - Atlantic Oligocene/Miocene Boundary Paleoproductivity Data

description: The Oligocene to Miocene boundary (23 Ma) marks one of the major Cenozoic cooling steps. A corresponding but slightly lagging d13C maximum in benthic foraminifer calcite of globally distributed sediment cores has been attributed to increased organic matter burial, either on land or in the oceans. To test this idea we reconstruct the organic carbon flux to the sea floor at three Atlantic Ocean Drilling Program (ODP) Sites using benthic foraminiferal accumulation rates (BFAR) and compare them with the stable isotope records. Our data show that the d18O and d13C maximum that characterizes the Oligocene/Miocene boundary is accompanied by a pronounced maximum in BFAR derived paleoproductivity at two of the sites. At tropical Atlantic Site 926 the paleoproductivity increase at the Oligocene/Miocene boundary is smaller than at the higher latitude sites, but high resolution sampling of a 2 million year interval (22-24 Ma) reveals that on eccentricity time scales productivity and stable isotope records are significantly correlated. The productivity records are in phase with the d18O and d13C records at the short-term (~125 ky) component of eccentricity. At the long-term eccentricity period (~400 ky) productivity is in phase with d18O but leads the d13C record by an amount that is consistent with published phase lags between the d18O and d13C records. These results imply that there was enhanced flux of organic matter to the ocean floor during the O/M climate transition and support that marine primary productivity may have played a role in the carbon cycle and atmospheric CO2 draw-down at this time.

title: NOAA/WDS Paleoclimatology - Lapa Grande Cave, Brazil Holocene Speleothem Oxygen Isotope Data

description: Well-dated high-resolution oxygen isotope records of speleothems in central-eastern Brazil spanning from 1.3 to 10.2 kyr B.P. reveal that the occurrence of abrupt variations in monsoon precipitation is not random. They show a striking match with Bond events and a significant pacing at ~800 yr, a dominant periodicity present in sea surface temperature records from both the North Atlantic and equatorial Pacific Oceans that is possibly related to periods of low solar activity (high 14C based on the atmospheric 14C record). The precipitation variations over central-eastern Brazil are broadly antiphased with the Asian and Indian Monsoons during Bond events and show marked differences in duration and structure between the early and late Holocene. Our results suggest that these abrupt multicentennial precipitation events are primarily linked to changes in the North Atlantic meridional overturning circulation (AMOC). Anomalous cross-equatorial flow induced by negative AMOC phases may have modulated not only the monsoon in South America but also affected El Nino-like conditions in the tropical Pacific during the Holocene.
