title: NOAA/WDS Paleoclimatology - Late Eocene marine Osmium isotope record from Italy, the Southern Atlantic, and the Eastern Pacific

description: A reconstruction of seawater 187Os/188Os ratios during the late Eocene (∼36–34 Ma), based upon bulk sediment analyses from the sub-Antarctic Southern Atlantic Ocean (Ocean Drilling Program (ODP) Site 1090), Eastern Equatorial Pacific Ocean (ODP Sites 1218 and 1219) and the uplifted (land-based) Tethyan section (Massignano, Italy), confirms that the previously reported abrupt shift to lower 187Os/188Os is a unique global feature of the marine Os isotope record that occurs in magnetochron C16n.1n. This feature is interpreted to represent the change in seawater 187Os/188Os caused by the Popigai impact event. Higher in the Massignano section, two other iridium anomalies previously proposed to represent additional impact events do not show a comparable excursion to low 187Os/188Os, suggesting that these horizons do not record multiple large impacts. Comparison of records from three different ocean basins indicates that seawater 187Os/188Os begins to decline in advance of the Popigai impact event. At Massignano this decline coincides with a previously reported episode of elevated 3He flux, suggesting that increased influx of interplanetary dust particles (IDPs) contributed to the pre-impact shift in 187Os/188Os and not to the longer-term latest Eocene 187Os/188Os decline that occurred ∼1 million year after the Popigai impact event.

title: NOAA/WDS Paleoclimatology - Nebraska Sand Hills Lake Level Data over the last 6000 years

description: High-resolution paleohydrological reconstructions were carried out in five shallow lakes in the Nebraska Sand Hills across an east–west transect in order to 1) determine whether long-term droughts of the past 4000 years were spatially and temporally coherent across the region, 2) distinguish local variation in climate or hydrology from regional patterns of change, and 3) compare the paleolimnological results with the existing dune-inferred drought records. Diatom- inferred lake-level was reconstructed for all sites and compared with other regional records. Alterations between high and low lake-levels were frequent during the past 4000 years, which suggests that shifts between dry and wet periods were prevalent across the Sand Hills. Extended multi-decadal to centennial-scale droughts were more common prior to 2000 years BP, while the last two millennia were hydrologically more variable and climate conditions alternated on shorter timescales. Despite some discrepancies among the five records, the paleohydrological reconstructions refine the Holocene drought history of the Nebraska Sand Hills, particularly between ~2200 and 4000 cal a BP. Many of the observed drought events are contemporaneous with severe droughts documented at sites in the northern Great Plains and Rocky Mountains, lending support for the severity and regional significance of these events in western North America.

title: NOAA/WDS Paleoclimatology - North Pond, Alberta Carbon/Nitrogen Data over the last 5000 years

description: Shrinking glaciers and snowpacks are reducing discharge in rivers that drain the central Rocky Mountain region – water that supports downstream societies and ecosystems of western North America. However, a new 5200-year record of Lake Athabasca water-level variations, which serves as a sensitive gauge of past changes in alpine-sourced river discharge, reveals that western Canadian society has developed during a rare period of unusually abundant water ‘subsidized’ by prior glacier expansion. As the ‘alpine water tap’ closes, much drier times are ahead. Future water availability is likely to become similar to the mid-Holocene when Lake Athabasca dropped 2–4 m below the twentieth-century mean. Regions dependent on high-elevation runoff (i.e., western North America) must prepare to cope with impending water scarcity of magnitude not yet experienced since European settlement.

title: NOAA/WDS Paleoclimatology - Lapland 1,600 Year Tree-Ring Carbon Isotope Data

description: The large volcanic eruptions of AD 536 and 540 led to climate cooling and contributed to hardships of Late Antiquity societies throughout Eurasia, and triggered a major environmental event in the historical Roman Empire. Our set of stable carbon isotope records from subfossil tree rings demonstrates a strong negative excursion in AD 536 and 541-544. Modern data from these sites show that carbon isotope variations are driven by solar radiation. A model based on sixth century isotopes reconstruct an irradiance anomaly for AD 536 and 541-544 of nearly three standard deviations below the mean value based on modern data. This anomaly can be explained by a volcanic dust veil reducing solar radiation and thus primary production threatening food security over a multitude of years. We offer a hypothesis that persistently low irradiance contributed to remarkably simultaneous outbreaks of famine and Justinianic plague in the eastern Roman Empire with adverse effects on crop production and photosynthesis of the vitamin D in human skin and thus, collectively, human health. Our results provide a hitherto unstudied proxy for exploring the mechanisms of 'volcanic summers' to demonstrate the post-eruption deficiencies in sunlight and to explain the human consequences during such calamity years.

title: NOAA/WDS Paleoclimatology - North GRIP Ice Core Last Glacial d15N and Temperature Reconstruction

description: In order to reconstruct the temperature of the North Greenland Ice Core Project (NGRIP) site, new measurements of d15N have been performed covering the time period from the beginning of the Holocene to Dansgaard-Oeschger (DO) event 8. Together with previously measured and mostly published d15N data, we present for the first time a NGRIP temperature reconstruction for the whole last glacial period from 10 to 120 kyr b2k (thousand years before 2000 AD) including every DO event based on d15N isotope measurements combined with a firn densification and heat diffusion model. The detected temperature rises at the onset of DO events range from 5 C (DO 25) up to 16.5 C (DO 11) with an uncertainty of +/- 3 C. To bring measured and modelled data into agreement, we had to reduce the accumulation rate given by the NGRIP ss09sea06bm timescale in some periods by 30 to 35%, especially during the last glacial maximum. A comparison between reconstructed temperature and d18Oice data confirms that the isotopic composition of the stadial was strongly influenced by seasonality. We evidence an anticorrelation between the variations of the d18Oice sensitivity to temperature (referred to as alpha) and obliquity in agreement with a simple Rayleigh distillation model. Finally, we suggest that alpha might be influenced by the Northern Hemisphere ice sheet volume.

title: NOAA/WDS Paleoclimatology - Grimsey, North Icelandic Shelf Annual d13C Data over the Last Millennium

description: Given the rapid increase in atmospheric carbon dioxide concentrations (pCO2) over the industrial era there is a pressing need to construct long term records of natural carbon cycling prior to this perturbation and to develop a more robust understanding of the role the oceans play in the sequestration of atmospheric carbon. Here we reconstruct the historical biological and climatic controls on the carbon isotopic (d13C-shell) composition of the North Icelandic shelf waters over the last millennium derived from the shells of the long-lived marine bivalve mollusc Arctica islandica. Variability in the annually resolved d13C-shell record is dominated by multi-decadal variability with a negative trend (-0.003 ± 0.002‰ yr-1) over the industrial era (1800-2000 CE). This trend is consistent with the marine Suess effect brought about by the sequestration of isotopically light carbon (d13C of CO2) derived from the burning of fossil fuels. Comparison of the d13C-shell record with contemporary proxy archives, over the last millennium, and instrumental data over the 20th century, highlight that both biological (primary productivity) and physical environmental factors such as relative shifts in the proportion of Subpolar Mode Waters and Arctic Intermediate Waters entrained onto the North Icelandic shelf, atmospheric circulation patterns associated with the winter North Atlantic Oscillation, and subpolar gyre sea surface temperatures and salinity, are the likely mechanisms that contribute to natural variations in seawater d13C variability on the North Icelandic shelf. Contrasting d13C fractionation processes associated with these biological and physical mechanisms likely cause the attenuated local marine Suess effect signal at this locality.

title: NOAA/WDS Paleoclimatology - Kulishu Cave, China Speleothem Oxygen Isotope Data 13.8-10.4 ky BP

description: Chinese speleothems (cave deposits) preserve a remarkable paleoclimate record in their oxygen isotope ratios (d18O); the precise interpretation of this record has been the subject of stimulating discussion. Most studies link the d18O variability in Chinese speleothems to regional summer monsoon rainfall and/or rainfall integrated between tropical sources and cave sites. Discussion has centered on mechanisms behind this link as well as the location and seasonality of hypothesized rainfall changes. Until now, these hypotheses were not directly tested in speleothems because conventional drill sampling techniques are insufficient for measuring speleothem d18O at seasonal resolution. Here we use an ion microprobe to analyze seasonal d18O variability in an annually banded stalagmite from Kulishu Cave (northeastern China) that grew during the last deglaciation. The new seasonal resolution data show that the stalagmite d18O values record two aspects of regional monsoon dynamics: (1) changes in the isotopic fractionation of water vapor sourced from both the Indian and Pacific Oceans, and (2) the annual proportion of summer monsoon rainfall, which was systematically greater during the Holocene and Bølling-Allerød than during the Younger Dryas. Both relate to regional rainfall; the isotopic fractionation changes also relate to rainfall integrated from tropical sources.

title: NOAA/WDS Paleoclimatology - Shenqi Cave, Southeastern Tibetan Plateau 2300 Year Speleothem d18O Data

description: Climate changes on Southeastern Tibetan Plateau have important impacts on social and economic development, as well as the ecosystem of southwestern China and Indo-China Peninsula. Here, we collected two stalagmites from Shenqi (Miraculous) cave in southern Sichuan, China. The stalagmite d18O record shows good coherence with local instrumental rainfall record, as well as tree ring- and pollen-based moisture reconstructions from southeastern Tibetan Plateau during overlapped time periods. As a result, we reconstructed high-resolution (~4.9 yrs) monsoon precipitation variations on southeastern Tibetan Plateau over the past 2300 years by using the combined stalagmite d18O record. 
The result reveals an overall decreasing precipitation trend, with two most notable wet periods occurred in 60-280 AD and 370-510 AD. The most remarkably dry period is the recent 200 years. Some decadal scale wet and dry intervals were also identified. The abnormal drought during 1160-1245 AD might have accelerated Dali kingdom's demise at 1253 AD. Power spectrum analysis indicated significant 373-, 187-, 22-, 12- and 11- yr cycles in our stalagmite record, suggesting the impact of solar activity. Increased monsoon precipitation on southeastern TP was observed in solar activity minima during the last millennium. We further synthesized an integrated precipitation record for southwestern China and discussed spatial patterns of precipitation over China during the last two millennia. The comparisons confirm a "dry southern and wet northern" pattern in monsoonal China during the Medieval Warm Period and a "wet southern and dry northern" pattern during the Little Ice Age and Dark Age Cold Period. Solar activity, the strength of westerly jet and summer monsoon, as well as the SST of tropical Indo-Pacific might play important roles on the rainfall spatial patterns over monsoonal China during the last 2000 years.

title: NOAA/WDS Paleoclimatology - Ta'u, American Samoa Coral d18O Data from 1520-2011 CE

description: A 492-year long, continuous d18O time series from a massive Porites coral colony in Ta'u, American Samoa, records contrasting responses to different types of ENSO (El Niño-Southern Oscillation) through a mixed sea surface temperature (SST) and salinity signal. Currently, conventional El Niño (La Niña) events generate cold and salty (warm and fresh) anomalies at Ta'u, while Modoki El Niño (La Niña) events warm (cool) the waters at Ta'u. Over the course of the 20th century, the Ta'u d18O record underwent a polarity shift in its response to conventional ENSO: a warm and fresh (cool and salty) response to El Niño (La Niña) was replaced by the opposite pattern. We interpret this as evidence for the movement of the Eastern Pacific ENSO null zone, the narrow band of the surface ocean where SST variability is not on average correlated with ENSO. This movement appears to be related to overall shrinking of the ENSO footprint over the 20th century. We infer no such trend in the Modoki footprint. The five century long Ta'u record shows dramatic, century-scale changes in ENSO-band variability. Comparisons with other ENSO reconstructions lead to conflicting interpretations: the Ta'u coral may have recorded changes in the strength of ENSO or in its spatial footprint. Changes in the spatial footprint manifest as a changing sensitivity to ENSO at any given location, presenting challenges to established methods of ENSO reconstruction.
