title: NOAA/WDS Paleoclimatology - Abraham Reef - Stable Isotope Data

description: Radiocarbon (Δ14C) and stable isotope (δ18O and δ13C) records are presented for biannual samples from a 323-year banded coral series collected from the southern Great Barrier Reef, Australia. The high-precision Δ14C record contains variations on an interannual timescale, that are particularly large between A.D. 1680 and 1730. By comparison with tree ring Δ14C records [Stuiver and Quay, 1980; M. Stuiver, personal communication, 1992), it is clear that these shifts were not caused by changes in the Δ14C of atmospheric CO2. Changes in vertical mixing and large scale advective changes involving source waters to the western Coral Sea region are likely processes that could account for these large Δ14C variations. Most low Δ14C values for the period A.D. 1635-1875 coincide with El Niño/Southern Oscillation (ENSO) events as reported by Quinn et al. [1987] for the eastern tropical Pacific. However, ENSO does not explain all of the variations, especially during 1875–1920 when Δ14C values remained high. Cross-spectral analysis of the early half of the Δ14C and δ18O records (A.D. 1635–1795) reveals that the 6-year period is coherent; this coherency is not present in the latter half (A.D. 1797–1957) of the isotope records. These data support the concept of century timescale changes in the nature of ENSO, as it is manifest in the southwestern Pacific. Our coral record shows no evidence of a Suess effect, the lowering of Δ14C from late 1800s through 1955 due mainly to CO2 input from fossil fuel burning. This is coincident with the change we observe in the nature of ENSO and is further evidence that a long-term change in mixing of upper waters occurred in this region.

title: NOAA/WDS Paleoclimatology - Fenland, Eastern England Tree-ring Stable Isotope and Total Ring Width Data from 4584-4206 cal yrBP

description: Tree ring-based climate reconstructions are fundamental for high-resolution paleoclimatology, but only a few of them extend back into the mid-Holocene (8,200–4,200 years BP). Here, we present annually-resolved tree-ring stable carbon and oxygen isotopes (δ13C and δ18O) from subfossil yew (Taxus baccata) wood excavated in the Fenland region of eastern England. We develop an eco-physiological model to reconstruct hydroclimate variability from 5,224 to 4,813 ± 4 and 4,612–4,195 ± 6 cal. years BP. Our findings suggest that a relative sea-level rise in the North Sea, riverine flooding, and a prolonged negative phase of the North Atlantic Oscillation caused unusually wet conditions around 4,200 years ago when yew woodlands in eastern England disappeared. We expect our study to stimulate high-resolution stable isotope measurements in relict wood and encourage the integration of terrestrial and marine proxy archives to reconstruct the causes and consequences of large-scale climate variations around the still debated 4.2 ka event.

title: NOAA/WDS Paleoclimatology - Speleothem Oxygen Isotope Data from Zhangjia Cave, SW China within the Last Deglaciation

description: Extensive research has explored how sweet spot conditions influence climate variability in the nonlinear Earth system. However, their effects throughout deglaciations remain unclear. Based on an annual-laminated speleothem δ18O record with unprecedented chronology precision, we first identified a two-step termination of the Asian Heinrich Period-1 at 15.11 and 14.69 ky BP (thousand years before present, where the present is 1950 CE), each marked by a centennial-scale strengthening of the Asian summer monsoon (ASM), in contrast to centennial-scale ASM weakening events observed at 17.8 and 16.09 ky BP. These transitions occurred under intermediate CO2 and ice volume conditions, which dynamically paced the Atlantic Meridional Overturning Circulation (AMOC) fluctuations and the subsequent reoccurrence of ASM events. It highlights the role of stochastic resonance in nonlinear climate system. Additionally, these AMOC/ASM events also resonated with abrupt CO2 risings across various pervasive modes of variability, which account for half of total CO2 rise during last deglaciation. This substantial contribution to CO2 increases played a key role in ice termination.

title: NOAA/WDS Paleoclimatology - Sant'Angelo Cave Geochemical Data from 47800 to 6600 Cal Yr BP

description: Similarly to the effects of current climate change, the last deglaciation (Termination I) rapidly altered northern latitude temperatures and ice-sheet extent, as well as the Atlantic Meridional Overturning Circulation. However, it is still unclear how these changes propagated and impacted the central Mediterranean continental rainfall variability. This prevents a full understanding on how global warming will affect Mediterranean areas in the future. Here, we present a high-resolution reconstruction of rainfall changes in the central Mediterranean across Termination I, based on a novel δ18O time series from a southern Italian stalagmite. Across Termination I the availability of Atlantic moisture varied in response to northern latitude temperature increases (decreases) and ice-sheet decreases (increases), promoting a higher (lower) intensity of the Atlantic Meridional Overturning Circulation, and resulting in a relatively wetter (drier) climate in the Mediterranean. In the light of future warming, this study emphasises the role of high-latitude climate changes in causing rainfall variation in highly populated Mediterranean areas.

title: NOAA/WDS Paleoclimatology - São Bernardo Cave, São Matheus Cave Geochemical Data from 28000 to -60 Cal Yr BP

description: Most reconstructions of the South American Monsoon System (SAMS) over the last two millennia are based on δ18O records from locations at high-elevation sites in the Andes, which are not influenced by the South Atlantic Convergence Zone (SACZ). Yet the SACZ is a key driver of SAMS variability over much of Brazil. Here we use two new δ18O records from speleothems sampled in the central and southwestern portions of the SACZ core to show that the SAMS was not varying in phase over the entire tropical continent during the last two millennia. In fact, speleothem records located to the northeast of the SACZ record precipitation variations that are antiphased with similar records on the opposite side of the SACZ, in particular during the Little Ice Age period, while records close to the core of the SACZ axis show no significant departure from the mean state during this period.

title: NOAA/WDS Paleoclimatology - Therrell et al. 2006 Zimbabwe Summer Precipitation Reconstruction

description: We present the first tree-ring reconstruction of rainfall in tropical Africa using a 200-year regional chronology based on samples of Pterocarpus angolensis from Zimbabwe. The regional chronology is significantly correlated with summer rainfall (November–February) from 1901 to 1948, and the derived reconstruction explains 46% of the instrumental rainfall variance during this period. The reconstruction is well correlated with indices of the El Niño-southern oscillation (ENSO), and national maize yields. An aridity trend in instrumental rainfall beginning in about 1960 is partially reproduced in the reconstruction, and similar trends are evident in the nineteenth century. A decadal-scale drought reconstructed from 1882 to 1896 matches the most severe sustained drought during the instrumental period (1989–1995), and is confirmed in part by documentary evidence. An even more severe drought is indicated from 1859 to 1868 in both the tree-ring and documentary data, but its true magnitude is uncertain. A 6-year wet period at the turn of the nineteenth century (1897–1902) exceeds any wet episode during the instrumental era. The reconstruction exhibits spectral power at ENSO, decadal and multi-decadal frequencies. Composite analysis of global sea surface temperature during unusually wet and dry years also suggests a linkage between reconstructed rainfall and ENSO.
