title: NOAA/WDS Paleoclimatology - McKenna and Prell 2004 Globorotalia truncatulinoides (R) Mg/Ca Water Temperature Calibration

description: Recent work has provided useful Mg/Ca to water temperature calibrations for shallow-dwelling planktonic foraminifer species. Globorotalia truncatulinoides (right coiling (R)) is a deep-dwelling species that can serve as a source of information about the temporal variability in the water characteristics of the thermocline. We present a temperature calibration for the Mg/Ca in the shell of G. truncatulinoides (R) and examine some of the practical issues associated with evaluating the usefulness of the technique. The Mg/Ca in the primary and the secondary calcite of individual G. truncatulinoides (R) correlates exponentially with water column temperatures, showing a change of ∼10% in the Mg/Ca per 1°C (R2 = 0.92). A limited comparison with plankton tow samples demonstrates that the average Mg/Ca temperature was offset +1°C from the average temperature calculated using the δ18O calibration of O'Neil et al. [1969], and the Mg/Ca temperatures have a range similar to the δ18O temperatures. Comparisons of the [Mg] in the core top samples to water depth of deposition indicates that dissolution does not alter the measured value of Mg in the primary calcite.

title: NOAA/WDS Paleoclimatology - GISP2, Taylor Dome - Methane Concentration Data

description: We present high resolution records of atmospheric methane from the GISP2 (Greenland Ice Sheet Project 2) ice core for four rapid climate transitions that occurred during the past 50 ka: the end of the Younger Dryas at 11.8 ka, the beginning of the Bølling-Allerød period at 14.8 ka, the beginning of interstadial 8 at 38.2 ka, and the beginning of interstadial 12 at 45.5 ka. During these events, atmospheric methane concentrations increased by 200–300 ppb over time periods of 100–300 years, significantly more slowly than associated temperature and snow accumulation changes recorded in the ice core record. We suggest that the slower rise in methane concentration may reflect the timescale of terrestrial ecosystem response to rapid climate change. We find no evidence for rapid, massive methane emissions that might be associated with large-scale decomposition of methane hydrates in sediments. With additional results from the Taylor Dome Ice Core (Antarctica) we also reconstruct changes in the interpolar methane gradient (an indicator of the geographical distribution of methane sources) associated with some of the rapid changes in atmospheric methane. The results indicate that the rise in methane at the beginning of the Bølling-Allerød period and the later rise at the end of the Younger Dryas were driven by increases in both tropical and boreal methane sources. During the Younger Dryas (a 1.3 ka cold period during the last deglaciation) the relative contribution from boreal sources was reduced relative to the early and middle Holocene periods.

title: NOAA/WDS Paleoclimatology - NOAA Paleoclimatology Reconstructions Network

description: High-resolution temperature reconstructions (typically annually to seasonally resolved) have played a key role in understanding paleoclimate immediately prior to the beginning of the instrumental record, especially when calibrated to form an extension of comparable instrumental data coverage (global, hemispheric, and regional). Such calibration allows the information in the instrumental record to be quantitatively extended backward in time in an objective way, enabling description of much longer term fluctuations in climate than possible with instrumental data alone, although with significantly increased uncertainties inherent in proxy-based reconstructions. This data brief describes a newly integrated archive of nearly all the high-resolution temperature reconstructions of the past 2+ millennia included in NOAA's National Climatic Data Center, from small-regional to global scale, which also have been recalibrated to a standard set of instrumental data. Examination of the spectral structure of the data is additionally provided.
description: NOAA Paleoclimatology Paleoclimate Network (PCN) version 2.0.0, 
including 92 high-resolution temperature records over the past 
2+ millennia, 1209 proxy data time series used by Mann et al. 
(2008, 2009), and instrumental data of the HadCRUT3 and HadCRUT3v 
combined global land and ocean gridded (5°x5°) surface temperature 
data sets, averaged to annual and seasonal time resolution by 
NOAA Paleoclimatology.  The Reconstructions, Proxy, and Instrumental
data sets are described in detail below.


The RECONSTRUCTIONS include global, hemispheric, regional, 
and local reconstructions, generally with annual time-step resolution.  
The records come with many categories of metadata, including complete 
citations to original publications, seasonal period reconstructed 
(when applicable), anomaly period (if reconstructions are anomalies), 
latitude/longitude coverage, and URLs to the original NOAA Paleoclimate 
web pages from which the data were drawn.  Each record is available 
as a separate ASCII file with fixed header and data formats, 
allowing machine reading of the data and time-step information.  
All the records together are also available in netCDF, ASCII, 
and Excel formats, including the complete metadata within the 
files themselves.  The netCDF format version is provided in two files, 
the first with each record represented as a separate variable and the 
second as a time-by-study array in which each record is represented 
as a component of the study dimension.  Sample scripts to open the 
netCDF versions in the R programming environment are also provided.

title: NOAA/WDS Paleoclimatology - Arabian Sea Holocene G. bulloides Data

description: During the last ice age, the Indian Ocean southwest monsoon exhibited abrupt changes that were closely correlated with millennial-scale climate events in the North Atlantic region, suggesting a mechanistic link. In the Holocene epoch, which had a more stable climate, the amplitude of abrupt changes in North Atlantic climate was much smaller, and it has been unclear whether these changes are related to monsoon variability. Here we present a continuous record of centennial-scale monsoon variability throughout the Holocene from rapidly accumulating and minimally bioturbated sediments in the anoxic Arabian Sea. Our monsoon proxy record reveals several intervals of weak summer monsoon that coincide with cold periods documented in the North Atlantic region-including the most recent climate changes from the Medieval Warm Period to the Little Ice Age and then to the present. We therefore suggest that the link between North Atlantic climate and the Asian monsoon is a persistent aspect of global climate.

title: NOAA/WDS Paleoclimatology - East Rongbuk Glacier - Oxygen Isotope and Major Ion Data

description: An 80.4 m ice core was recovered from a site at 6500 m above sea level on the East Rongbuk Glacier, Mt. Qomolangma (Everest) in August 1998. A total of 1816 samples were analyzed for major ions (Ca2+, Mg2+, Na+, K+, NH4+, SO42−, NO3−, and Cl−) and stable oxygen isotope ratios (δ18O). The core was dated by the seasonal variations along the stable isotopic and major ionic profiles, and the dating was verified by the double β activity peaks corresponding to the annual layers 1963 and 1954, the highest sodium peak corresponding to a major monsoon failure occurred in 1876–1877, and several identified sulfate volcanic signals. The NH4+ level remained fairly constant from 1840s to 1940s, followed by a substantial increase until the end of 1980s, then a slight decrease during the recent decade, which may provide information on change in the regional agriculture activities.

title: NOAA/WDS Paleoclimatology - Sea Surface Temperature Estimates in the Equatorial and North Atlantic

description: A new method of past sea surface temperature (SST) reconstruction based on the modern analog technique (Prell, 1985) and on the indirect approach (Bartlein et al., 1986) has been developed: the revised analog method (RAM). Applied to planktonic foraminifera, this technique leads to significant improvements in modern SST reconstruction with respect to former methods: our estimates are characterized by much lower residuals and a better coverage of the observed SST range. Moreover, the error of RAM estimates of past SSTs is lower than that associated with former reconstructions, particularly at middle and high latitudes. In low latitudes, cold season SSTs reconstructed by RAM during glacials are 1°–3°C lower than previously estimated. Our results tend thus to reconcile paleoestimates of glacial temperatures based on planktonic microfossils and on continental data in the tropics.

title: NOAA/WDS Paleoclimatology - Barium accumulation in the South Atlantic during the past 190,000 years

description: Extensive investigations of sedimentary barium were performed in the southern South Atlantic in order to assess the reliability of the barium signal in Antarctic sediments as a proxy for paleoproductivity. Maximum accumulation rates of excess barium were calculated for the Antarctic zone south of the polar front where silica accumulates at high rates. The correspondence between barium and opal supports the applicability of barium as a proxy for productivity. Within the Antarctic zone north of today's average sea ice maximum, interglacial vertical rain rates of excess barium are high, with a maximum occurring during the last deglaciation and early Holocene and during oxygen isotope chronozone 5.5. During these periods, the maximum silica accumulation was supposedly located south of the polar front. Glacial paleoproductivity, instead, was low within the Antarctic zone. North of the polar front, significantly higher barium accumulation occurs during glacial times. The vertical rain rates, however, are as high as in the glacial Antarctic zone. Therefore there was no evidence for an increased productivity in the glacial Southern Ocean.
