title: NOAA/WDS Paleoclimatology - Dome Fuji, Antarctica 1993 Shallow Core 1-cm Electrical Conductivity Measurements (ECM)

description: To make a pilot-hole for deep core drilling at Dome Fuji Station, East Queen Maud Land, Antarctica, shallow ice core drilling was conducted to a depth of 112.59 m by electro-mechanical drill. Core logging, measurements of impermeability and bulk density were conducted in situ and most of another analysis was done in Japan.  Much depth hoar developed at Dome Fuji Station. However, it did not influence the densification rate, which mainly depends on temperature. Air bubble close-off starts from about 90 m depth. Much accumulation at one time occurs during marine cyclones at Dome Fuji Station.
description: In 1993, the 34th wintering party of the Japanese Antarctic Research Expediton  (JARE-34) conducted shallow core drilling at Dome Fuji Station, East Antarctica to make a pilot borehole for deep core drilling. Then, an ice core of 112.59 depth was recovered by electro-mechanical drill.  The core was brought to the National Institute of Polar Research (NIPR: Tokyo). In 1995, core analysis was started to determine: (1) the recent circumstance of deposition process at Dome Fuji Station, and (2) the formation process of stratigraphic structure and its characteristics in a shallow layer. Chronology, chemical and physical properties are examined. The ECM signal was measured at DF 1250 V and about -15C. The data were corrected to values corresponding to -15C by use of the Arrhenius law for temperature dependence (Neftel, 1985). Density was also corrected for effects of firn density. Analogue ECM data were digitized at 1 mm intervals. After taking the moving average of 10 data, Data set was made at intervals of 1 cm.

title: NOAA/WDS Paleoclimatology - Bhutan 638 Year Tree-Ring Summer Temperature Reconstruction

description: High-resolution tree-ring reconstructions from the Himalaya provide essential context for assessing impacts of future climate change on regional water reserves and downstream agriculture. Here we evaluate a small network of tree-ring chronologies from Bhutan to produce a 638-year summer temperature reconstruction, from 1376 - 2013 CE. Relative to the 1950 - 2013 CE average summer temperature three prominent cold periods stand out, 2 in the mid 15th century, and one in the late 17th century. The warmest period began in the first decade of the 21st century coinciding with the timing of general glacier recession in the eastern Himalaya that continues to the present. The Bhutan temperature reconstruction exhibits a significant correlation to known volcanic eruptions (p = 97%) and anomalously cold periods appear to align with solar irradiance minima in the 15th, late 17th and early 19th centuries, implying a link between solar variability and decadal-scale temperature variability.

title: NOAA/WDS Paleoclimatology - Benguela Upwelling System Hydrogen and Carbon Isotope Data since the mid-Pliocene

description: Future projections of southwestern African hydroclimate are highly uncertain. However, insights from past warm climates, like the Pliocene, can reveal mechanisms of future change and help benchmark models. Using leaf wax hydrogen isotopes to reconstruct precipitation (δDp) from Namibia over the past 5 million years, we find a long-term depletion trend (−50‰). Empirical mode decomposition indicates this trend is linked to sea surface temperatures (SSTs) within the Benguela Upwelling System, but modulated by Indian Ocean SSTs on shorter timescales. The influence of SSTs on reconstructed regional hydroclimate is similar to that observed during modern Benguela Niño events, which bring extreme flooding to the region. Isotope-enabled simulations and PlioMIP2 results suggest that capturing a Benguela Niño-like state is key to accurately simulating Pliocene, and future, regional hydroclimate. This has implications for future regional climate, since an increased frequency of Benguela Niños poses risk to the ecosystems and industries in the region.

title: NOAA/WDS Paleoclimatology - Baw Baw Tree ring width, PAGES Australasia 2k Version

description: We investigate the causes of variability in a tree‐ring chronology comprising data from Eucalyptus pauciflora Sieb. Ex. Spreng. at the alpine treeline on the Kosciuszko Plateau in New South Wales, Australia. Following verification of crossdating in a subset of the available data, we found that ring width correlates significantly with net radiation, precipitation and mean minimum and maximum air temperature during the preceding winter and spring of the growing season. Our results for spring are consistent with the impact of climate on tree growth in alpine woodlands reported in previous studies. Analyses of snow‐depth data revealed negative correlations with ring width throughout winter and spring. Our results indicate that low temperature and high precipitation during winter negatively affect the growth of E. pauciflora by prolonging spring snow cover. Ring width also correlates significantly with an index of soil dryness and flow in rivers with their headwaters in the Kosciuszko plateau. Given the apparent sensitivity of our chronology to climate and snow conditions, our results suggest that tree‐ring chronologies comprising data from E. pauciflora at the alpine treeline have potential for climatological and hydrological reconstruction in southeast Australia.

title: NOAA/WDS Paleoclimatology - North-Western Argentina composite 2 Tree ring width, PAGES LOTRED-SA Version

description: This study presents a comprehensive assessment of high-resolution Southern Hemisphere (SH) paleoarchives covering the last 2000 years. We identified 174 monthly to annually resolved climate proxy (tree ring, coral, ice core, documentary, speleothem and sedimentary) records from the Hemisphere. We assess the interannual and decadal sensitivity of each proxy record to large-scale circulation indices from the Pacific, Indian and Southern Ocean regions over the twentieth century. We then analyse the potential of this newly expanded palaeoclimate network to collectively represent predictands (sea surface temperature, sea level pressure, surface air temperature and precipitation) commonly used in climate reconstructions. The key dynamical centres-of-action of the equatorial Indo-Pacific are well captured by the palaeoclimate network, indicating that there is considerable reconstruction potential in this region, particularly in the post AD 1600 period when a number of long coral records are available. Current spatiotemporal gaps in data coverage and regions where significant potential for future proxy collection exists are discussed. We then highlight the need for new and extended records from key dynamical regions of the Southern Hemisphere. Although large-scale climate field reconstructions for the SH are in their infancy, we report that excellent progress in the development of regional proxies now makes plausible estimates of continental- to hemispheric-scale climate variations possible.

title: NOAA/WDS Paleoclimatology - PAGES Ocean2K 400 Year Coral Data and Tropical SST Reconstructions

description: Most annually resolved climate reconstructions of the Common Era are based on terrestrial data, making it a challenge to independently assess how recent climate changes have affected the oceans. Here, as part of the Past Global Changes (PAGES) Ocean2K project, we present four regionally calibrated and validated reconstructions of sea-surface temperatures in the tropics, based on fifty-seven published and publicly archived marine paleoclimate datasets derived exclusively from tropical coral archives. Validation exercises suggest that our reconstructions are interpretable for much of the past 400 years, depending on the availability of paleoclimate data within, and the reconstruction validation statistics for, each target region. Analysis of the trends in the data suggests that the Indian, western Pacific, and western Atlantic ocean regions were cooling until modern warming began around the 1830s. The early 1800s were an exceptionally cool period in the Indo-Pacific region, likely due to multiple large tropical volcanic eruptions occurring in the early 19th century. Decadal-scale variability is a quasi-persistent feature of all basins. 20th century warming associated with greenhouse gas emissions is apparent in the Indian, West Pacific, and Western Atlantic Oceans, but we find no evidence that either natural or anthropogenic forcings have altered El Nino-Southern Oscillation (ENSO)-related variance in tropical SSTs. Our marine-based regional paleoclimate reconstructions serve as benchmarks against which terrestrial reconstructions as well as climate model simulations can be compared, and as a basis for studying the processes by which the tropical oceans mediate climate variability and change.

title: NOAA/WDS Paleoclimatology - Modern and Holocene Stable Isotope and Trace Element Records from Pacific Panama

description: Climate change is now the leading cause of coral-reef degradation and is altering the adaptive landscape of coral populations. Increasing sea temperatures and declining carbonate saturation states are inhibiting short-term rates of coral calcification, carbonate precipitation, and submarine cementation. A critical challenge to coral-reef conservation is understanding the mechanisms by which environmental perturbations scale up to influence long-term rates of reef-framework construction and ecosystem function. Here we reconstruct climatic and oceanographic variability using corals sampled from a 6750-year core from Pacific Panamá. Simultaneous reconstructions of coral paleophysiology and reef accretion allowed us to identify the climatic and biotic thresholds associated with a 2500-year hiatus in vertical accretion beginning ~4100 years ago.  Stronger upwelling, cooler sea temperatures and greater precipitation—indicators of La Niña-like conditions—were closely associated with abrupt reef-shutdown. The physiological condition of the corals deteriorated at the onset of the hiatus, corroborating theoretical predictions that the tipping points of radical ecosystem transitions should be manifested sublethally in the biotic constituents. Future climate change could cause similar threshold behaviors, leading to another shutdown in reef development in the tropical eastern Pacific.
description: In this study we investigated the long-term impacts of environmental variability on coral physiology and reef development in the TEP to ascertain the climatic, oceanographic, and biotic controls on ecosystem state in the past. We quantified the range of environmental conditions that corals experienced during the past ~6750 years to determine if significant changes in climate or oceanography were associated with changes in coral physiology or reef accretion. Our paleoclimatic reconstructions are based on temperature calibrations for Sr/Ca and oxygen isotopes (d18O) using modern Pocillopora damicornis colonies from Contadora. We measured bulk geochemistry from Pocillopora coral skeletons in the core to to reconstruct (i) paleotemperature and paleosalinity from Sr/Ca and d18O, (ii) oceanic paleoproductivity (upwelling) primarily from the local reservoir correction DeltaR (=Delta14C), and to a lesser extent Ba/Ca, and (iii) coral physiology from d13C and B/Ca.

title: NOAA/WDS Paleoclimatology - Ray and Adams 2001 GIS-based Vegetation Map of the World at the Last Glacial Maximum

description: A preliminary, broad-scale vegetation map reconstruction for use by archaeologists and anthropologists is presented here for the world at the Last Glacial Maximum (18,000 BP, but broadly representing the interval from 25,000 to 15,000 BP). The global LGM map was produced from a range of literature and map sources, and drawn on a GIS with topographic information. Extended coastlines due to LGM sea-level drop were obtained using bathymetric information. The map is available in image and Geographic Information System (GIS) formats, on a global or regional basis. Accompanying each regional map is a bibliography detailing the principal literature sources of evidence on Late Quaternary palaeovegetation and climates. The maps presented here are merely a preliminary attempt at appraisal of current knowledge and opinion, and future updated versions are intended as more information on LGM environments becomes available. Nevertheless, together with the accompanying citation summary they should provide a valuable and readily accessible source of information on current opinion in the Quaternary community. It is also hoped that the maps will themselves act as a catalyst for archaeologists to use their own data to contribute to the broader climatic/palaeovegetational picture.

title: NOAA/WDS Paleoclimatology - GRIP Ice Core 248 KYr H2O2, HCHO, NH4+ and Ca2+ Data

description: A new deep core drilling operation started in 1990 central Greenland and in 1992 reached the bottom at a depth of 3028 m.b. surface. Taking advantage of recent developments in the analytical technique of chemical trace species, continuous high resolution measurements of H2O2, HCHO, NH4+ and Ca2+ concentrations were performed directly on the ice core in the field. During the 1991 season all four components were measured simultaneously between 1300 m.b. surface and 2300 m.b. surface, corresponding to the time interval between 8000 and 38,000 years B.P. In this paper an overview of the results and our first interpretations in terms of climatic changes are given.
