title: NOAA/WDS Paleoclimatology - Nino 3 Index Reconstruction Data of the Eastern Pacific Ocean from 1408 to 1978 CE

description: The instrumental record is too brief for evaluation of the El Niño-Southern Oscillation (ENSO) system and its long-term response to climate forcing. To supplement these data, we use a new reconstruction of December-February Niño-3 sea surface temperatures based on subtropical North American tree-ring records to investigate aspects of ENSO variability over the past six centuries (AD 1408-1978). Spectral analyses reveal that the reconstruction best resolves variability within the "classical" ENSO band of 2-8 years. A low amplitude ENSO epoch in the 17th to 18th centuries broadly coincides with "Little Ice Age" conditions over much of the globe. The detailed behavior shows good agreement with shorter tree-ring reconstructions of ENSO over the past few centuries, but differs at times from other longer coral ENSO records and recent model simulations of past ENSO behavior. We discuss possible reasons for these discrepancies.
description: Reconstruction of the Nino3 Index of El Nino-Southern Oscillation variability, for the months of December through February each year. 175 chronologies from the southwestern USA and Mexico were screened as potential predictors (lags t; t+1) of the instrumental Niño-3 data in principal component regression. Both the tree-ring and instrumental data were prewhitened using autoregressive modeling, with instrumental persistence added back in to the reconstruction. Series significantly correlated (> 0.05 level) with the instrumental record were used to reconstruct Niño-3 SSTs. A nested procedure (in which the number of chronologies declines back in time) was used to develop the longest possible reconstruction, with iterative nests beginning in 1408, 1507, 1608 and 1709. The final reconstruction was developed by averaging early and late calibration reconstructions within each nest, and splicing these series together after their variance and mean had been adjusted to that of the 1709-1978 nest. All chronologies were compiled from indices of tree growth (primarily ring width) detrended to remove biological trends (Cook 1985).

title: NOAA/WDS Paleoclimatology - Precipitation Oxygen Isotopes from Florida

description: Stable isotopic compositions of oxygen, carbon, and hydrogen were used to identify the sources of water and of organic matter, pathway reactions, evaporation processes, and transfer mechanisms among various water types as well as the extent of water-rock reactions. An attempt to understand the isotopic compositions of the hydrological cycle of west-central Florida, their variations, baseline levels and controlling mechanisms constitutes parts of this dissertation.

A comparison of δ18O in rainwater (weighted mean = -4.4 o/oo) and surficial ground water (mean = -4.1 o/oo) indicates that rainwater recharges the surficial aquifer with only a minor isotopic change. δ18O vs δD plots of rainwater and ground waters suggest that recently recharged water in the upper Floridan aquifer is similar to today's rainwater. As shown by calculations, carbonate aquifers react extensively with the ground waters in the upper Floridan aquifer through time to cause a shift of δ18O from -4.4 to -2.8 o/oo. Changes in δ18O and δ13CDIC in ground waters of the upper Floridan aquifer in two flow paths suggest that the confined nature of the aquifer causes the difference. Parts of the upper Floridan aquifer supply freshwater to rivers discharging into Tampa Bay as evidenced by similarities in δ180 and δ13CDIC of both freshwater types. Evaporation may play a role in shifting the δ18O of rivers from ground-water source of -2.8 o/oo to -2.3 o/oo.

δ18O and δ13C in Tampa-Bay water correlate linearly with salinity. Based on isotopic mass balance calculations, the replacement time of Tampa-Bay water is about 67 days. Mirror Lake has invariant δ18O during a one-year study, and has a calculated replacement time for its water of 43 days.

title: NOAA/WDS Paleoclimatology - Northeast Atlantic MD95-2006 MIS3 Faunal SST, IRD, and Isotope Data

description: There is much uncertainty surrounding the mechanisms that forced the abrupt climate fluctuations found in many palaeoclimate records during Marine Isotope Stage (MIS)-3. One of the processes thought to be involved in these events is the Atlantic Meridional Overturning Circulation (MOC), which exhibited large changes in its dominant mode throughout the last glacial period. Giant piston core MD95-2006 from the northeast Atlantic Ocean records a suite of palaeoceanographic proxies related to the activity of both surface and deep water masses through a period of MIS-3 when abrupt climate fluctuations were extremely pronounced. A two-stage progression of surface water warming during interstadial warm events is proposed, with initial warming related to the northward advection of a thin warm surface layer within the North Atlantic Current, which only extended into deeper surface layers as the interstadial progressed. Benthic foraminifera isotope data also show millennial-scale oscillations but of a different structure to the abrupt surface water changes. These changes are argued to partly be related to the influence of low-salinity deepwater brines. The influence of deepwater brines over the site of MD95-2006 reached a maximum at times of rapid warming of surface waters. This observation supports the suggestion that brine formation may have helped to destabilize the accumulation of warm, saline surface waters at low latitudes, helping to force the MOC into a warm mode of operation. The contribution of deepwater brines relative to other mechanisms proposed to alter the state of the MOC needs to be examined further in future studies.

title: NOAA/WDS Paleoclimatology - Hoti Cave, Oman 9-6 KYrBP Stalagmite Oxygen Isotope Data

description: Variations in the amount of solar radiation reaching the Earth are thought to influence climate, but the extent of this influence on timescales of millennia to decades is unclear. A number of climate records show correlations between solar cycles and climate, but the absolute changes in solar intensity over the range of decades to millennia are small and the influence of solar flux on climate is not well established. The formation of stalagmites in northern Oman has recorded past northward shifts of the intertropical convergence zone, whose northward migration stops near the southern shoreline of Arabia in the present climate. Here we present a high-resolution record of oxygen isotope variations, for the period from 9.6 to 6.1 kyr before present, in a Th-U-dated stalagmite from Oman. The d18O record from the stalagmite, which serves as a proxy for variations in the tropical circulation and monsoon rainfall, allows us to make a direct comparison of the d18O record with the D14C record from tree rings, which largely reflects changes in solar activity. The excellent correlation between the two records suggests that one of the primary controls on centennial- to decadal-scale changes in tropical rainfall and monsoon intensity during this time are variations in solar radiation.
description: High-resolution stalagmite oxygen isotope data for 9-6 KYrBP from Hoti Cave, Oman. Hoti cave is located in northern Oman, on the southwestern side of the Oman mountains. The modern climate of the area is arid to semi-arid, and the area is not at present affected by the Indian Ocean monsoon system. Stalagmite H5 from Hoti cave is dated with 12 Th-U ages, and the d18O record covers 9.6 to 6.1 kyr before present. The Hoti cave d18O record provides a high-resolution time series of the intensity of Indian Ocean monsoonal rainfall.

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 - Byrd and Siple Dome 9-21 ka CO2 data on GICC05 Timescale

description: Antarctic ice cores provide clear evidence of a close coupling between variations in Antarctic temperature and the atmospheric concentration of CO2 during the glacial/interglacial cycles of at least the past 800-thousand years. Precise information on the relative timing of the temperature and CO2 changes can assist in refining our understanding of the physical processes involved in this coupling. Here, we focus on the last deglaciation, 19 000 to 11 000 yr before present, during which CO2 concentrations increased by ~80 parts per million by volume and Antarctic temperature increased by ~10°C. Utilising a recently developed proxy for regional Antarctic temperature, derived from five near-coastal ice cores and two ice core CO2 records with high dating precision, we show that the increase in CO2 likely lagged the increase in regional Antarctic temperature by less than 400 yr and that even a short lead of CO2 over temperature cannot be excluded. This result, consistent for both CO2 records, implies a faster coupling between temperature and CO2 than previous estimates, which had permitted up to millennial-scale lags.

title: NOAA/WDS Paleoclimatology - Greenland Lake Transect Modern Carbon and Hydrogen Isotope Data

description: Sedimentary plant wax distributions and isotopic compositions are powerful, widely applied paleoenvironmental proxies. However, there is conflicting evidence on the behavior of these proxies at high-latitude sites, where extreme climate and light conditions may uniquely influence plant physiology and growth. Here, we present modern sedimentary n-alkane and n-alkanoic acid abundances and compound-specific (d2H and d13C) isotope values from a 22-lake transect extending from northwest to southernmost Greenland, covering a large latitudinal and climatic gradient. Sedimentary plant waxes are similar in abundance and carbon isotopic composition across the transect, suggesting no major differences in biologic sources. There are strong correlations (r = 0.8-0.9) between d2H values of many long-chain sedimentary waxes and those of modelled precipitation, with n-alkanes more tightly correlated to precipitation than n-alkanoic acids. Data presented here also demonstrate that d2H values of mid-chain sedimentary waxes do not strongly correlate to the d2H values of lake water when it decouples isotopically from precipitation (i.e. in glacier-fed and evaporatively-enriched lakes). This calls into question the common interpretation that mid-chain sedimentary waxes can be ascribed to aquatic plants. We contextualize our Greenland data with an updated global dataset of d2H values of modern sedimentary waxes and precipitation. This update adds 100 + lakes from recently published literature to the seminal review presented by Sachse et al. (2012). This large new compilation suggests a global average apparent fractionation including Arctic data between n-C28 alkanoic acids and annual precipitation (EC28/ANN) of -99permil, and between n-C29 alkanes and annual precipitation (EC29/ANN) of -121permil. The latter value is remarkably consistent with the value first reported by Sachse et al. (2012).

title: NOAA/WDS Paleoclimatology - Wu fire data from Lower Middle Mountain - IMPD USLMM001

description: We selected a warm/dry mixed conifer forest (ponderosa pine, white fir, Douglas-fir, and aspen) in southwestern Colorado to reconstruct historical conditions of fire regime and forest structure in preparation for an experiment in ecological restoration. Although mixed conifer forests are of high ecological and social value in the Southwest, they have been less studied than ponderosa pine forests.  Fire-scar analysis on a 150-ha area showed recurring fires at mean intervals of 24 years (all fires with minimum of 2 sample trees scarred) to 32 years (fire scarring 25% or more of sample trees) from the 16th century until the abrupt cessation of fire after 1868, concurrent with European settlement. There was no evidence in age or species-specific data of severe burning at the scale of the study blocks (approximately 200 ha). The forest remained unharvested throughout most of the 20th century, until a cut in the early 1990s removed approximately equal basal areas of ponderosa pine and white fir. Forest structure had already changed substantially, however. Total basal area increased from an average of 11 m^2 ha^-1 in 1870 to 27 m^2 ha^-1 in 2003, despite harvesting of at least 8.4 m^2 ha^-1. Ponderosa pine declined from representing nearly two-thirds of basal area in 1870 to one-third in 2003. The other species increased dramatically, especially white fir, which went from 12% to 35% of basal area and dominated stand density with an average of 392 trees ha^-1. Total tree density increased from 142 trees ha^-1 in 1870 to 677 trees ha^-1 in 2003. The ecological changes that occurred here since the 19th century have been in exactly the opposite direction considering the warm, fire-favoring climate expected in the 21st century.  If warm/dry mixed conifer forests of southern Colorado are to have a reasonable chance for persistence under the future climate regime, restoring conditions more similar to the frequently burned, open forests of the past is likely to be a useful starting point.
