title: NOAA/WDS Paleoclimatology - Madang Lagoon - del18O Data  - 1995

description: The western equatorial Pacific warm pool is believed to be the source region of a substantial proportion of the world's inter-annual climate variability, including the globally significant El Nin˜o-Southern Oscillation. Here new data are presented on changes in the climate of this region over the past 70 yr, based on analysis of the stable oxygen isotopic composition of annually banded, massive corals living on the north coast of Papua New Guinea. In this area, the coincidence of abundant and isotopically light rainfall with small seasonal and inter-annual changes in temperature means that the coral skeletal δ18O record may be reliably interpreted in terms of rainfall variation. Since the abundance of rainfall is governed by the intensity of deep atmospheric convection, the coral records provide regionally significant, and regionally reproducible, climatic indices. In particular, the coral records indicate larger changes in the degree of coupling of the climate of the region with the Southern Oscillation than have hitherto been described. These changes in coupling, which accompany shifts in the dominant periodicities of inter-annual climate variation, are indicative of rapid and large-scale reorganisation of ocean-atmosphere interactions. The data indicate that from the 1920s to 1950s the western equatorial Pacific was less important in modulating Pacific and global inter-annual climatic variability than it has appeared to be subsequently. The reproducibility of the coral climate records, combined with the presence on the north coast of Papua New Guinea of extensive and well preserved raised reef terraces, leads to the potential for extending understanding of climatic variability in this globally important region back into the late Quaternary.
description: Samples were collected in 1991 and 1992 from massive Porites corals in Madang Lagoon (5 deg 13'S; 145deg 49'E, .2M Depth) and at Duranguit Reef, Laing Island (4deg 9'S; 144deg 53'E; 3M Depth), Bismark Sea coast, Papua New Guinea. The isotope record displays a marked seasonality, with an average annual range of 0.3-0.4% and as much as 0.8% PDB. Smoothed coral 18O records are correlated with both Madang rainfall and Tahiti-Darwin SOI.

title: NOAA/WDS Paleoclimatology - Esper - Pakistan low Cha1 - JUSP - ITRDB PAKI005

description: We present an analysis of 28 juniper tree-ring sites sampled over the last decades by several research teams in the Tien Shan and Karakorum mountains of western central Asia. Ring-width chronologies were developed on a site-by-site basis, using a detrending technique designed to retain low-frequency climate variations. Site chronologies were grouped according to their distance from the upper timberline in the Tien Shan (~3,400 m a.s.l.) and Karakorum (~4,000 m), and low- and high-elevation composite chronologies combining data from both mountain systems developed. Comparison of these elevational subsets revealed significant coherence (r = 0.72) over the 1438–1995 common period, which is inconsistent with the concept of differing environmental signals captured in tree-ring data along elevational gradients. It is hypothesized that the uniform growth behavior in central Asian juniper trees has been forced by solar radiation variations controlled via cloud cover changes, but verification of this assumption requires further fieldwork. The high-elevation composite chronology was further compared with existing temperature reconstructions from the Karakorum and Tien Shan, and long-term trend differences discussed. We concluded that the extent of warmth during medieval times cannot be precisely estimated based on ring-width data currently available.

title: NOAA/WDS Paleoclimatology - Northeast Atlantic SU81-18 Deglacial 231Pa/230Th Data

description: A first study from the subtropical western Atlantic, using 231Pa/230Th ratios as a kinematic proxy for deep water circulation, provided compelling evidence for a strong link between climate and the rate of Meridional Overturning Circulation (MOC) over the last deglaciation. However, these results warrant confirmation from additional locations and water depths because the interpretation of the sedimentary 231Pa/230Th ratio in terms of circulation vigor can be biased by variations in particle flux and composition. We have measured 231Pa/230Th in a core from the Iberian margin, in the Northeastern Atlantic basin, and have compared these new results to the data from the western Atlantic basin. We find that the reduction in the circulation during H1 and YD and the subsequent increases first recognized in the sediment deposited on Bermuda Rise are also evident in the eastern basin, in a totally different sedimentary regime, confirming that sedimentary 231Pa/230Th ratios record basin-wide changes in deep water circulation. However, some differences between the eastern and western records are also recognized, providing preliminary evidence to differentiate between renewal rates in the two North Atlantic basins and between shallower and deeper overturning. Our results suggest the possible existence of two sources of Glacial North Atlantic Intermediate Deep Water (GNAIW), one in the south Labrador Sea and another west of Rockall Plateau. Both sources contributed to the meridional overturning but the two had different sensitivity to meltwater from the Laurentide and the Fennoscandian ice sheets during the deglaciation. These results indicate that additional information on the geometry and strength of the ventilation of the deep Atlantic can be obtained by contrasting the evolution of sediment 231Pa/230Th in different sections of the Atlantic Ocean.

title: NOAA/WDS Paleoclimatology - Lake V57, Nunavut 2,000 Year Midge Inferred Temperatures

description: A lake sediment core recovered from Lake V57 on Victoria Island, Nunavut, Canada, spanning the last 2000 years, was analyzed for sub-fossil midge remains and organic-matter content estimated by loss-on-ignition (LOI)). Significant changes in midge community composition occurred during the last 2000 years, with a distinct midge community appearing after 1600 AD. The chironomid community between 0 and 1600 AD was dominated by Heterotrissocladius, Tanytarsus, Abiskomyia, and Paracladius. At approximately 1600 AD, 
Heterotrissocladius decreased in relative abundance and taxa such as Corynocera ambigua, C. oliveri, Psectrocladius sordidellus type, and Pentanneurini increased in relative abundance. 
Previously published midge-based inference models for average July air temperature (AJAT) and summer surface-water temperature (SSWT) were applied to the subfossil midge stratigraphy.  The AJAT reconstruction indicates relatively cool conditions existed between 1100 and 1600 AD, with exceptional warming occurring after 1600 AD, as lake productivity inferred from organic-matter content increased concomitantly with midge-inferred AJAT and SSWT. The cooler conditions between 1200 and 1600 AD, and the pattern of warming over recent centuries inferred from Lake V57 is broadly consistent with temperature-sensitive biogenic silica records from other sites in the central Canadian Arctic and the treeline zone 
to the south suggesting a regionally synchronous response to climate forcing.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
