description: New and updated multi-century tree-ring chronologies from living oak trees, remnants, and archeological beams from across the Driftless Area of southwest Wisconsin and northeast Iowa, USA, were developed to fill a spatial gap in the network of available tree-ring chronologies. We produced a robust 303-year summer drought reconstruction (June-August Palmer's Modified Drought Index (PMDI): r2 = 0.45) that identified clusters of extreme droughts and pluvials (PMDI <= -4.0 or >= 4.0) in the early 1700s and more even distributions of drought conditions, with the exception of the post 1930s period when drought became relatively infrequent. Compared to the Living Blended Drought Atlas (LBDA) and the North American Drought Atlas (NADA), our reconstruction more accurately represented moderate moisture conditions across the Driftless Area, the NADA and LBDA more closely represented extreme pluvials, and our reconstruction and the LBDA better represented extreme drought years. The three reconstructions largely captured the same high-frequency variability in drought conditions and differed most at low frequencies. Significant correlations were identified between our reconstruction and corn (r = 0.30, n = 91, p = 0.002) and soybean (r = 0.25, n  = 81, p = 0.012) yields, with the strength of the correlations increasing over recent decades suggesting a tighter coupling of interannual climate variability and crop productivity in the region. Superposed epoch analyses indicated significantly wetter conditions in the Driftless Area two years after major volcanic eruptions. In the context of long-term climatic variability, the Driftless Oaks drought reconstruction demonstrated that drought and pluvial conditions more extreme than those experienced during the instrumental record have occurred in the past.

title: NOAA/WDS Paleoclimatology - South China Sea 1996-2002 Weekly-Monthly Resolution Coral d13C and d18O Data

description: Great efforts have been made to understand the impacts of the 1997 Indonesian wildfires on land ecology and human health, yet its influences on marine environments are poorly understood owing to sparse observations. Here we present weekly to monthly resolution coral d13C records across the South China Sea in conjunction with a regional ocean general circulation model to study the effects of these cataclysmic wildfires on nearby oceans. Large and persistent negative d13C excursions were found in corals from the interior South China Sea several months after the wildfires. This delay indicates that the 13C-depleted ash fallout was distributed by ocean currents rather than direct atmospheric transport, which is supported by the results of our numerical model. Thus, the impacts of tropical wildfires on marine ecology may last for 1 year and extend thousands of kilometers from the burning center.

title: NOAA/WDS Paleoclimatology - Northwestern Pacific Core-top Nd Isotope Data, Deglaciation Records of Nd Isotopes and SST Reconstruction

description: During Heinrich Stadial 1 (HS1, 18.0–14.7 kyr ago), the Bering and Okhotsk Seas in the western Subarctic Pacific (SAP) exhibited boundary conditions that enhanced intermediate water convection. However, little is known about the quantitative contribution of the intermediate waters from the Bering and Okhotsk Sea (BSIW and OSIW) to ventilation in the open SAP intermediate–deep layers. In this study, we analyzed the neodymium (Nd) isotopes of fish debris (eNd-FD) from sediment cores in the Northwestern Pacific, and observed a reduction in eNd (up to –2.6) from the Last Glacial Maximum to HS1 at Sites MD01-2420 (2101 m) and KH99-3 ES (2388 m). The relevance of reduced HS1 eNd-FD shifts across the cores cannot be explained by the porewater influence, which generally changes authigenic eNd in opposite ways. Instead, as the eNd-FD shifts concurred with a reduction in the 14C ventilation age, HS1 eNd-FD shifts suggest the entrainment of younger and distinct eNd water mass sinking in the Okhotsk and/or Bering Seas. A mixing model applying Nd isotopes, their concentrations, and 14C ventilation ages of BSIW, OSIW, and the Lower Circumpolar Deep Water showed that during HS1, BSIW (36%–41%) was more conducive to the water mass at Site MD01-2420, compared to OSIW (4%–8%). We argue that the Bering Sea has wider and deeper connections (Kamchatka and Near Straits, ~4400–2200 m) with the western SAP, and the deep conduit would enable BSIW to more effectively flow out into the open Northwestern Pacific deep layer.
description: In this study, authigenic eNd-FD and eNd-PK records from Cores MD01-2420, KH99-3 ES, SHY2MC, and SHY3MC were generated and used to track vertical changes in the deep North Pacific eNd values during the last deglaciation. In addition, eNd-FD from 11 core-top sediments in the range of depths in the Northwestern Pacific were measured.

title: NOAA/WDS Paleoclimatology - Nikolay Lake Holocene Surface Air Temperature Reconstructions

description: Radiocarbon-dated pollen, rhizopod, chironomid and total organic carbon (TOC) records from Nikolay Lake (73°20′N, 124°12′E) and a pollen record from a nearby peat sequence are used for a detailed environmental reconstruction of the Holocene in the Lena Delta area. Shrubby Alnus fruticosa and Betula exilis tundra existed during 10,300–4800 cal. yr BP and gradually disappeared after that time. Climate reconstructions based on the pollen and chironomid records suggest that the climate during ca. 10,300–9200 cal. yr BP was up to 2–3 °C warmer than the present day. Pollen-based reconstructions show that the climate was relatively warm during 9200–6000 cal. yr BP and rather unstable between ca. 5800–3700 cal. yr BP. Both the qualitative interpretation of pollen data and the results of quantitative reconstruction indicate that climate and vegetation became similar to modern-day conditions after ca. 3600 cal. yr BP. The chironomid-based temperature reconstruction suggests a relatively warm period between ca. 2300 and 1400 cal. yr BP, which corresponds to the slightly warmer climate conditions reconstructed from the pollen. Modern chironomid and rhizopod assemblages were established after ca. 1400 cal. yr BP.

title: NOAA/WDS Paleoclimatology - Queensland Late Holocene Multiproxy Hydroclimate Database

description: Palaeoclimate data relating to hydroclimate variability over the past millennia have a vital contribution to make to the water sector globally. The water industry faces considerable challenges accessing climate data sets that extend beyond that of historical gauging stations. Without this, variability around the extremes of floods and droughts is unknown and stress-testing infrastructure design and water demands is challenging. User-friendly access to relevant palaeoclimate data is now essential, and importantly, an efficient process to determine which proxies are most relevant to a planning scenario, and geographic area of interest. This paper presents PalaeoWISE (Palaeoclimate Data for Water Industry and Security Planning) a fully integrated, and quality-assured database of proxy data extracted from data repositories and publications collated in Linked Paleo Data (LiPD) format. We demonstrate the application of the database in Queensland, one of Australia's most hydrologically extreme states. The database and resultant hydroclimate correlations provides both the scientific community, and water resource managers, with a valuable resource to better manage for future climate changes.

description: In this contribution we document the radial growth rates of seven tropical species largely used for timbers in the Bolivian Cerrado, the region with the largest wood production in Bolivia. Inter-annual variations in tree-ring widths were measured on cross-sections from Amburana cearensis, Cedrela fissilis, Platimiscium ulei, Centrolobium microchaete, Hymenaea courbaril, Anadenanthera colubrina and Ficus boliviana. For a common period of 100 years, the mean annual diametric growth ranged from 0.55 to 1.05 cm year−1 in Platimiscium ulei and Ficus boliviana, respectively. Mean cumulative variations in diameter growth of Centrolobium microchaete at six different sites ranged from 32.7 to 38.6 cm over a 100-year period. Variations in tree ages to reach the minimum cutting diameter (MCD) of 40 cm in the Chiquitano district ranged from 32 to >140 years, whereas in the Guarayos district (MCD = 50 cm) from 38 to 140 years. For Centrolobium microchaete, temporal variations for reaching the MCD ranged from 35 to 140 years and from 45 to 110 years for the Chiquitano and Guarayos districts, respectively. Since large differences in cumulative diametric growth were recorded between species and between sites for the same species, difference in growth rates between species and sites should be taken into consideration to ensure sustainable forest management in tropical dry forests. Biological rotation ages, estimated on the temporal evolution of the mean and current annual basal area, occur at ages over 80 years for most selected species. This information has significant implications for the management of the forests and suggests that the current cutting cycles of 20 years greatly overestimate the growth rate of tree species in the Boliviano Cerrado forest.

title: NOAA/WDS Paleoclimatology - O'Connor fire data from Pinalenos_D4, Southeast Arizona - IMPD USD4-001

description: In recent decades fire size and severity have been increasing in high elevation forests of the American Southwest. Ecological outcomes of these increases are difficult to gauge without an historical context for the role of fire in these systems prior to interruption by Euro-American land uses. Across the gradient of forest types in the Pinaleño Mountains, a Sky Island system in southeast Arizona that experienced two relatively large high-severity fires in the last two decades, we compared fire characteristics and climate associations before and after the onset of fire exclusion to determine the degree of similarity between past and recent fires. We use a gridded fire scar and demography sampling network to reconstruct spatially explicit estimates of fire extent and burn severity, as well as climate associations of fires from individual site to landscape scales from 1640 to 2008 C.E. We found that patterns of fire frequency, size, and severity were relatively stable for at least several centuries prior to 1880. A combination of livestock grazing and active fire suppression after circa 1880 led to (1) a significant reduction in fire spread but not fire ignition, (2) a conversion of more than 80% of the landscape from a frequent, low to mixed-severity fire regime to an infrequent mixed to high-severity fire regime, and (3) an increase in fuel continuity within a mid-elevation zone of dry mixed-conifer forest, resulting in increased opportunities for surface and crown fire spread into higher elevation mesic forests. The two most recent fires affecting mesic forests were associated with drought and temperature conditions that were not exceptional in the historical record but that resulted in a relative proportion of high burn severity up to four times that of previous large fires. The ecological effects of these recent fires appear to be more severe than any fire in the reconstructed period, casting uncertainty upon the recovery of historical species composition in high-severity burn patches. Significant changes to the spatial pattern, frequency, and climate associations of spreading fires after 1880 suggest that limits to fuel loading and fuel connectivity sustained by frequent fire have been removed. Coinciding factors of high fuel continuity and fuel loading, projected lengthening of the fire season, and increased variability in seasonal precipitation suggest that large high-severity fires, especially in mixed-conifer forests, will become the predominant fire type without aggressive actions to reduce fuel continuity and restore fire-resilient forest structure and species composition.

title: NOAA/WDS Paleoclimatology - Quaternary Arctic Ocean Foraminifer Amino Acid Racemization Data

description: We report the results of amino acid racemization (AAR) analyses of aspartic and glutamic acids in the planktic foraminifera, Neogloboquadrina pachyderma, and the benthic species, Cibicidoides wuellerstorfi, collected from sediment cores from the Arctic Ocean. The cores were retrieved at various deep-sea sites of the Arctic, which cover a large geographical area; from the Greenland and Iceland seas to the Alpha and Lomonosov Ridges in the central Arctic Ocean. Age models for the investigated sediments were developed by multiple dating techniques, including oxygen isotope stratigraphy, magnetostratigraphy, bio-, litho-, and cyclostratigraphy. The extent of racemization (D/L values) was determined on 95 samples (1028 subsamples) and shows a progressive increase downcore for both foraminifera species. Differences in the rates of racemization between the species were established by analysing specimens of both species from the same stratigraphic levels (n = 21). Aspartic acid and glutamic acid racemize on average 16±2 % and 23±3 % faster, respectively, in C. wuellerstorfi than in N. pachyderma. D/L values typically increase with sample age, with a trend that follows a simple power function. Scatter around least square regression fits are larger for samples from the central Arctic Ocean than for those from the Nordic Seas. Calibrating the rate of racemization in C. wuellerstorfi using independently dated samples from the Greenland and Iceland seas for the past 400 ka enables estimation of sample ages from the central Arctic Ocean, where bottom water temperatures are similar. The resulting ages are older than expected when considering the existing age models for the central Arctic Ocean cores. These results confirm that the differences are not due to taxonomic effects and further warrant a critical evaluation of existing Arctic Ocean age models and the environmental factors that may influence racemisation rates in central Arctic Ocean sediments.

title: Data and R code for "Long-term cooperative relationships among vampire bats are not strongly predicted by their initial interactions as strangers"

description: In many group-living animals, survival and reproductive success depend on the formation of long-term social bonds. Yet it remains largely unclear why particular pairs of groupmates form social bonds and not others. Can social bond formation be reliably predicted from both individuals’ traits and behaviors at first encounter? Or do changes in the social environment over time make social bonding unpredictable? To begin to address these questions, we asked how well long-term cooperative relationships among vampire bats were predicted by how they interacted during their first encounter as introduced strangers. In Study 1, we found that the first 6 hours of observed interactions among unfamiliar bats co-housed in small cages did not clearly predict formation of allogrooming or food-sharing relationships over the next 10 months. In Study 2, we found that biologger-tracked first contacts during the first 4—24 hours together in a flight cage did not strongly predict allogrooming rates over the next 4 months. These results corroborate past evidence that social bonding is not reducible to the individual traits or behaviors observed at first encounter, because “first impressions” can be overshadowed by future interactions.
