title: NOAA/WDS Paleoclimatology - Northwest Pacific ODP882 Plio-Pleistocene Lithic and Diatom Isotope Data

description: Increases in the low-field mass-specific magnetic susceptibility (χ), dropstones and the terrigenous sediment component from Ocean Drilling Program (ODP) Site 882 (~ 45°N) have been interpreted to indicate a major onset of ice-rafting to the sub-Arctic northwest Pacific Ocean during marine isotope stage (MIS) G6 (from ~ 2.75 Ma). In contrast, studies of the terrigenous content of sediments cored downwind of ODP Site 882 indicate that dust and disseminated volcanic ash deposition in the sub-Arctic Pacific increased markedly during MIS G6. To investigate the relative contribution of dust, volcanic ash and ice rafting to the Pliocene χ increase, we present new high-resolution environmental magnetic and ice-rafted debris records from ODP Sites 882 and 885. Our results demonstrate that the χ increase at both sites across MIS G6 is predominantly controlled by a previously overlooked mixture of aeolian dust and volcanic ash. Our findings call into question the reliability of χ as a proxy for ice-rafting to the North Pacific. They also highlight a previously undocumented link between iron fertilisation and biogeochemical cycling in the North Pacific at a key stage during intensification of late Pliocene northern hemisphere glaciation.
description: Coarse lithic and diatom stable silicon isotope data 
for the Plio-Pleistocene from ODP Site 882A, determined 
using grain counts and a Finnigan MAT 253 stable isotope 
ratio mass spectrometre (using step-wise fluorination, 
with silicon collected as SiF4), respectively. 

ODP Site 882 lithic count data: 
Coarse lithic (>150um) abundance and flux estimates. 
Data reported as lithics and lithics plus fresh volcanic 
glass. Coarse lithic fluxes were calculated following 
Peck et al. (2007). Sedimentation rates were estimated from 
the Site 882 astronomical age model (Tiedemann and Haug, 1995) 
and shipboard derived dry-bulk density and GRAPE data. 

ODP Site 882 diatom isotopes: 
d30Si diatom measurements (n=30) for the interval ~2.85-2.55 Ma 
at ODP Site 882. Diatoms were extracted using existing techniques 
with analysed (75-150um) fractions dominated by two taxa; 
Coscinodiscus marginatus (Ehrenb.) and C. radiatus (Ehrenb.) 
(Swann, 2010). d30Sidiatom was analysed using step-wise 
fluorination at the NERC Isotope Geosciences Laboratory, U.K.,  	   
with silicon collected as SiF4. Measurements were made on a 
Finnigan MAT 253 stable isotope ratio mass spectrometre with 
values corrected using NIGL within-run laboratory diatom standard 
BFCmod against NBS28 (Leng and Sloane, 2008).

description: We present a millennial long dendroclimatic reconstruction of spring/summer precipitation for southern-central England. Previous research identified a significant moisture stress signal in ring-width data measured from oak trees growing in southern England. In this study, we build upon this earlier work, specifically targeting south-central England, to derive a well replicated oak ring-width composite chronology using both living and historical material.  The data-set includes 352 living trees (AD 1629-2009) and 1540 individual historical series (AD 663-1925). The period expressed by at least 50 trees in any year is AD 980-2009.  Calibration experiments identify the optimal seasonal predictand target as March-July precipitation (1901-2007: r2 = 0.33). However, comparison with the long Kew Gardens precipitation record indicates a weakening in tree-growth/climate response from ~1800 to 1920 which we speculate may be related to smoke and sulphur dioxide (SO2) emissions at that time which may have also contributed to a decrease in tree productivity. The time-series derived using the regional curve standardisation method to capture lower frequency information shows a mediaeval period with alternating multi-decade-long dry and wet periods, with AD 1153-1172 being the wettest reconstructed 20-year period in the whole record. Drier conditions are prevalent from ~1300 to the early sixteenth century followed by a period of increasing precipitation levels. The most recent four centuries of the record appear similar to the mediaeval period with multiple decade-long dry and wet periods. The late twentieth century is the second reconstructed wettest period. These centennial hydroclimatic trends are in broad agreement with independent regional scale hydroclimatic reconstructions from tree-ring (East Anglia), historical, speleothem and peat water level proxy archives in the United Kingdom and appear coupled with reconstructed sea surface temperature changes in the North Atlantic which in turn influence the Atlantic meridional overturning circulation and westerly airflow across the UK.

title: NOAA/WDS Paleoclimatology - Chongqing, Southwest China Holocene Stalagmite Oxygen Isotope Data

description: The timing and duration of the Holocene East Asian summer monsoon (EASM) maximum and the interpretation of Chinese stalagmite d18O records have long been disputed. Notably, interpretations of Holocene EASM variations are frequently based on a single record or study area and are often contradictory. In this study, we conducted stable isotope analyses of four Holocene stalagmites from Chongqing, southwest China. The results reveal differences in the timing of the Holocene EASM maximum and to try to resolve the inconsistency we analyzed and statistically integrated a total of 16 Holocene stalagmite records from 14 caves in the EASM region. The resulting synthesized Holocene stalagmite d18O (d18Osyn) record is in agreement with other EASM records and confirms that stalagmite d18O records are a valid indicator of EASM intensity, rather of local precipitation amount. The d18Osyn record shows that the EASM intensified rapidly from the onset of the early Holocene; notably, however, there were distinct EASM oscillations in the early Holocene, consisting of three abrupt millennial-scale events. This indicates that, contrary to several previous interpretations, the early Holocene EASM was unstable. Subsequently, during 8-6 kyr BP, the EASM was relatively stable and strong, with the strongest monsoon occurring during 8-7 kyr BP. This evidence of a stable and strong mid-Holocene EASM in eastern China is in accord with the classical view of a mid-Holocene Optimum in China.
description: Oxygen isotope (d18O) data from 4 Holocene stalagmites collected from three caves in Chongqing, southwest China. Included are data from stalagmite QM09 from Shizi Cave, stalagmites J12 and J13 from Jinfo Cave, stalagmite HF01 from Heifeng Cave, plus stacked data from all 4 Chongqing stalagmites.

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 - Brazil Margin Deglacial Benthic Stable Isotope Data

description: The initial rise in atmospheric CO2 during the last deglaciation was likely driven by input of carbon from a 13C-depleted reservoir [Schmitt et al., 2012]. Here we show that high resolution benthic foraminiferal records from the mid-depth Brazil Margin display an abrupt drop in d13C during Heinrich Stadial 1 (HS1) that is similar to but larger than in the atmosphere. Comparing the Brazil Margin results to published records from the North Atlantic, we are unable to account for the South Atlantic d13C data with conservative mixing between northern and southern component water masses. Rapid input of abyssal water from the Southeast Atlantic could account for deglacial d13C anomalies at the Brazil Margin but it would require a reversal in deep water flow direction compared to today. A new mid-depth water mass may explain similar HS1 d13C values in both the North and South Atlantic, but contrasting oxygen isotopic values between the two basins do not support the presence of a single dominant water mass at mid-depths. Instead, it appears that d13C behaved non-conservatively during the deglaciation, possibly reflecting the input of carbon from an isotopically depleted source.
description: Data include age model and stable isotopic data for Brazil Margin cores KNR159-5-17JPC, 78GGC, 33GGC, and 30GGC. Stable isotopic data for 36GGC and 42JPC are given in Curry and Oppo (2005). The age model for 36GGC is provided in Sortor and Lund (2011) while that for 42JPC is given in Hoffman and Lund (2012). Noted age reversals were not used in the age models. All calendar ages are based on the MARINE09 calibration curve assuming a Delta R of 0±200 years (1 sigma). For details see Tessin and Lund (2013). Isotopic measurements were based on individual tests of Cibicidoides spp. Bioturbated samples are noted where appropriate.  These values were not included in the running mean averages or the time slice averages presented in the paper.  Individual d13C values in 17JPC that were >0.3 per mil offset from the running mean value are also excluded.

description: We analyzed growth responses to climate of 24 tree-ring width and four maximum latewood density chronologies from the greater Tatra region in Poland and Slovakia. This network comprises 1183 ring-width and 153 density measurement series from four conifer species (Picea abies (L.) Karst., Larix decidua Mill., Abies alba (L.) Karst., and Pinus mugo (L.)) between 800 and 1550 m a.s.l. Individual spline detrending was used to retain annual to multi-decadal scale climate information in the data. Twentieth century temperature and precipitation data from 16 grid-boxes covering the 48-50 °N and 19-21 °E region were used for comparison. The network was analyzed to assess growth responses to climate as a function of species, elevation, parameter, frequency and site ecology. Twenty ring-width chronologies significantly correlated (P < 0.05) with June-July temperatures, whereas the latewood density chronologies were correlated with the April-September temperatures. Climatic effects of the previous-year summer generally did not significantly influence ring formation, whereas site elevation and frequency of growth variations (i.e., inter-annual and decadal) were significant variables in explaining growth response to climate. Response to precipitation increased with decreasing elevation. Correlations between summer temperatures and annual growth rates were lower for Larix decidua than for Picea abies. Principal component analysis identified five dominant eigenvectors that express somewhat contrasting climatic signals. The first principal component contained highest loadings from 11 Picea abies ring-width chronologies and one Pinus mugo ring-width chronology and explained 42% of the network's variance. The mean of these 12 high-elevation chronologies was significantly correlated at 0.62 with June-July temperatures, whereas the mean of three latewood density chronologies, which loaded most strongly on the fourth principal component, significantly correlated at 0.69 with April-September temperatures (P < 0.001 over the 1901-2002 period in both cases). These groupings allow for a robust estimation of June-July (1661-2004) and April-September (1709-2004) temperatures, respectively. Comparison with reconstructions from the Alps and Central Europe supports the general rule of the dominant influence of growing season temperature on high-elevation forest growth.

description: Cedrus atlantica ring width data are used to reconstruct long-term changes in the Palmer Drought Severity Index (PDSI) over the past 953 years in Morocco, NW Africa. The reconstruction captures the dry conditions since the 1980s well and places this extreme period within a millennium-long context. PDSI values were above average for most of the 1450-1980 period, which let recent drought appear exceptional. However, our results also indicate that this pluvial episode of the past millennium was preceded by generally drier conditions back to 1049. Comparison of PDSI estimates with large-scale pressure field reconstructions revealed steady synoptic patterns for drought conditions over the past 350 years. The long-term changes from initially dry to pluvial to recent dry conditions are similar to PDSI trends reported from N America, and we suggest that they are related to long-term temperature changes, potentially teleconnected with ENSO variability and forced by solar irradiance changes.

title: NOAA/WDS Paleoclimatology - Cape Bounty East Lake, Melville Island, Canada 2840 Year Grain Size Data

description: Annual grain-size variation was measured on the varved (annually laminated) lacustrine sediment from Cape Bounty East Lake using an innovative image analysis system. About 7100 images were acquired using a scanning electron microscope and processed to obtain measurement of particles from 2845 varves. Several particle-size distributions indices were calculated and can be linked to high-energy sedimentary facies. Moreover, the coarse grain size (98th percentile) of these high-energy facies is strongly correlated with summer rainfall (and also summer temperature) of instrumental data from nearby stations. Particle-size distributions show a similar trend through time, especially for the standard deviation and the 98th percentile. Climatic reconstruction suggests that Cape Bounty recently experienced an unprecedented increase of rainfall events since ~AD 1920. On the other hand, changes in varve thickness are weakly correlated with the particle-size distribution. Altogether, these results highlight the need to obtain annual grain-size data to identify a meteorological signal.
