title: NOAA/WDS Paleoclimatology - Touchan - Macchia Dell Arpa - PILA - ITRDB ITA067

description: The first large-scale network of tree-ring chronologies from the western Mediterranean (WM; 32°N–43°N, 10°W–17°E) is described and analyzed to identify the seasonal climatic signal in indices of annual ring width. Correlation and rotated empirical orthogonal function analyses are applied to 85 tree-ring series and corresponding gridded climate data to assess the climate signal embedded in the network. Chronologies range in length from 80 to 1129 years. Monthly correlations and partial correlations show overall positive associations for Pinus halepensis (PIHA) and Cedrus atlantica (CDAT) with winter (December–February) and spring (March–May) precipitation across this network. In both seasons, the precipitation correlation with PIHA is stronger, while CDAT chronologies tend to be longer. A combination of positive correlations between growth and winter–summer precipitation and negative partial correlations with growing season temperatures suggests that chronologies in at least part of the network reflect soil moisture and the integrated effects of precipitation and evapotranspiration signal. The range of climate response observed across this network reflects a combination of both species and geographic influences. Western Moroccan chronologies have the strongest association with the North Atlantic Oscillation.

title: NOAA/WDS Paleoclimatology - Wiles - Ellsworth Glacier Update - TSME - ITRDB AK203

description: Ring-width (RW) records from the Gulf of Alaska (GOA) have yielded a valuable long-term perspective for North Pacific changes on decadal to longer timescales in prior studies but contain a broad winter to late summer seasonal climate response. Similar to the highly climate-sensitive maximum latewood density (MXD) proxy, the blue intensity (BI) parameter has recently been shown to correlate well with year-to-year warm-season temperatures for a number of sites at northern latitudes. Since BI records are much less labour intensive and expensive to generate than MXD, such data hold great potential value for future tree-ring studies in the GOA and other regions in mid- to high latitudes. Here we explore the potential for improving tree-ring-based reconstructions using combinations of RW- and BI-related parameters (latewood BI and delta BI) from an experimental subset of samples at eight mountain hemlock (Tsuga mertensiana) sites along the GOA. This is the first study for the hemlock genus using BI data. We find that using either inverted latewood BI (LWBinv) or delta BI (DB) can improve the amount of explained temperature variance by > 10 % compared to RW alone, although the optimal target season shrinks to June–September, which may have implications for studying ocean–atmosphere variability in the region. One challenge in building these BI records is that resin extraction did not remove colour differences between the heartwood and sapwood; thus, long term trend biases, expressed as relatively warm temperatures in the 18th century, were noted when using the LWBinv data. Using DB appeared to overcome these trend biases, resulting in a reconstruction expressing 18th–19th century temperatures ca. 0.5 °C cooler than the 20th–21st centuries. This cool period agrees well with previous dendroclimatic studies and the glacial advance record in the region. Continuing BI measurement in the GOA region must focus on sampling and measuring more trees per site (> 20) and compiling more sites to overcome site-specific factors affecting climate response and using subfossil material to extend the record. Although LWBinv captures the inter-annual climate signal more strongly than DB, DB appears to better capture long-term secular trends that agree with other proxy archives in the region. Great care is needed, however, when implementing different detrending options and more experimentation is necessary to assess the utility of DB for different conifer species around the Northern Hemisphere.

title: NOAA/WDS Paleoclimatology - Ngamring Co Hydrogen Isotopic Composition of Long-Chain Fatty Acids and brGDGTs based Mean Annual Temperature over the last 18ka

description: Both the Indian Summer Monsoon (ISM) and glacier meltwater are suggested to significantly influence the modern discharge of the Yarlung Tsangpo River, which is the longest river of Tibet and is an important freshwater source for the local population as well as for the large populations in India and Bangladesh in the lower reaches. Understanding past hydroclimatic variations of the region is therefore important for predicting future changes under global warming scenarios. Here we present a continuous compound-specific hydrogen isotope record of sedimentary leaf waxes covering the past 18 ka (ka = 1000 yr) from Ngamring Co, located in the upper-middle Yarlung Tsangpo range, a typical monsoonal region, with the aim of documenting hydroclimatic changes since the last deglaciation. Compared with measurements of continuous scanning XRF and magnetic susceptibility, the dD at Ngamring Co is believed to reflect atmospheric circulation and glacial meltwater input rather than direct local humidity. In detail, the record indicates relatively enriched dD values during the Late Pleistocene, suggesting the predominance of the Westerlies and limited moisture delivery by the ISM, which was associated with cooling at high northern latitudes. The fast dD depletion indicates that ISM penetrated into TP since ~10.5 ka BP (before present, the present is 1950 CE), then the gradually increased dD values suggested the ISM attenuated in phase with summer insolation during early to middle Holocene. The negative deviation of dD (>80‰, abrupt depleted at 3 ka BP) since ~6 ka BP suggested glacier melting in the catchment and ended at ~0.2 ka BP, which emphasizes the glacial contribution to the hydroclimatic change in Yarlung Tsangpo watershed. Such depletion was also observed at Aweng Co in the western TP, which suggests that a glacier meltwater contribution to lakes and rivers may be a large-scale phenomenon on the TP. Comparison of the dD record from Ngamring Co with independent paleotemperature records indicates the control of summer temperature/insolation on glacier melting may not be the most important factor during the late Holocene, and instead we propose that the mean annual air temperature and glacier volume were more crucial to the melting process. If our inference is correct, the disappearance of a glacier from the Ngamring Co basin at ~0.2 ka BP is likely to be indicative of the fate of other glaciers on the TP under ongoing global warming. However, independent reconstructions of temperature and direct glacier dynamics from the same site are needed to validate our hypothesis.

title: NOAA/WDS Paleoclimatology - Hoti Cave, Oman d13C and d18O Speleothem Data over the past 2,581 years

description: In Arabia, the first half of the sixth century CE was marked by the demise of Himyar, the dominant power in Arabia until 525 CE. Important social and political changes followed, which promoted the disintegration of the major Arabian polities. Here, we present hydroclimate records from around Southern Arabia, including a new high-resolution stalagmite record from northern Oman. These records clearly indicate unprecedented droughts during the sixth century CE, with the most severe aridity persisting between ~500 and 530 CE. We suggest that such droughts undermined the resilience of Himyar and thereby contributed to the societal changes from which Islam emerged.

title: NOAA/WDS Paleoclimatology - Gulf of Aden DSDP231 Plio-Pleistocene Tephra Shard Counts and Geochemistry

description: We reconstruct a Plio-Pleistocene microscopic tephrostratigraphy for DSDP Site 231 in the Gulf of Aden. Systematic microtephrostratigraphy increases the potential for identifying tephra horizons for regional stratigraphic correlation and age control, as well as providing information about eruptive histories. Microtephra reveal three main pulses of volcanism c. 4.0-3.2 Ma, 2.4 Ma and 1.7-1.3 Ma, corresponding to peaks in volcanic activity recorded in the East African Rift System. Previous studies of DSDP Site 231 have reported six visible tephra horizons (up to 25 cm thick) with geochemical compositions matching East African tuffs. We find 68 additional microtephra horizons through microscopic examination of 1050 samples (each integrating c. 3 ka) in over 200 m of marine sediments. We report the major and minor element geochemical compositions of individual glass shards in six of these microtephra horizons and establish a robust correlation at 168.73 m to the Lokochot Tuff (3.58 Ma), which together with previously identified tephra, provides a tightly constrained chronostratigraphy for the mid Pliocene.
description: This dataset comprises semiquantitative counts of microtephra in DSDP Site 231, as well as for macroscopically visible tephra-rich horizons. The semi-quantitative shard counts are based on counting the same sized area of a smear slide, with similar grain coverage densities, after seiving to remove the fine fraction. Some of the tephra horizons have been further concentrated with heavy liquid separation and the shards analyzed geochemically by electron microprobe for the purposes of correlation with tephra layers in East Africa closer to source providing age control for the distal glass shard reported here. Age model from tephra and nannofossils datums correlated to dated records elsewhere.

title: NOAA/WDS Paleoclimatology - Martin Lake, Indiana Stable Isotope and Sediment Data over the past 7 ka

description: Variability in the source and seasonality of precipitation in the midcontinental United States during the Holocene was investigated using isotopic and sedimentological data from Martin Lake, northeastern Indiana, USA. Between 7100 and 4000 years before present (yr BP; present = 1950 CE), high δ18Ocal and δ13Ccal values with low variability indicate that moisture was predominantly derived from subtropical, southerly sources and delivered primarily during the warm season. Mean state shifts toward lower δ18Ocal and δ13Ccal occurred at ca. 4000 and 2550 yr BP, respectively, indicating an increase in northerly-sourced cold-season precipitation during the Late Holocene (i.e., the past 4200 years) and a subsequent reduction in warm season duration after 2550 yr BP. Record low %lithics from ca. 5000 to 4000 yr BP indicates major reductions in warm-season rain storms, consistent with regional evidence of drought at this time. An increase in the amplitude of centennial-scale variability in δ18Ocal, δ13Ccal, and %lithics after 1900 yr BP indicates greater precipitation source variability during the Common Era. During this interval, precipitation fluctuated between southerly-sourced, convective rainstorms when the Northern Hemisphere (NH) was warm (e.g., during the Medieval Climate Anomaly; 700–1000 yr BP) and northerly-sourced rain and snow when the NH was cool (e.g., during the Little Ice Age; 150–550 yr BP). These trends, especially the change at ca. 4000 yr BP, are consistent with other North American paleoclimate records that collectively suggest a continental-scale shift in precipitation seasonality during the Middle to Late Holocene transition as the tropical Pacific Ocean transitioned from La Niña-like conditions to a more El Niño-like mean state. Concurrent NH cooling and persistent El Niño-like conditions during the Late Holocene would have favored a southerly polar front jet stream with enhanced ridge and trough atmospheric circulation over North America – conditions resembling the positive mode of the Pacific-North American teleconnection (PNA). This would have increased interactions between high-latitude and subtropical airmasses over the midcontinent, increasing the proportion of northerly precipitation with low δ18O delivered during the cold season (i.e., snowfall) and during extended periods with +PNA-like atmospheric circulation (e.g., the Little Ice Age).
