title: NOAA/WDS Paleoclimatology - Antongil Bay, Madagascar Stable Isotope and Trace Element Data from 1965-2007 CE

description: Coral cores provide vital climate reconstructions for site-specific temporal variability in river flow and sediment load. Yet, their ability to record spatial differences across multiple catchments is relatively unknown. Here, we investigate spatial linkages between four coral proxies of terrestrial runoff and their relationships between sites. Coral cores were drilled in and around Antongil Bay, the largest bay in Madagascar, and individually analysed for fifteen years of continuous luminescence (G/B), Ba/Ca, d18Osw and d13C data. Each coral core was drilled close to individual river mouths (>= 7 km), and proxy data were compared to modelled river discharge and sediment runoff data for the three corresponding catchments. A reasonable agreement between terrestrial runoff proxies with modelled river discharge and sediment yield was observed. Some inconsistencies between proxy and modelled data are likely linked to proxy behaviour, watershed size and local environmental physiochemical parameters. In general, the further a coral resided from its river source, the weaker the proxy relationship was with modelled data and other corals, due to mixing gradients and currents. Nevertheless, we demonstrate that two coral Ba/Ca and luminescence (G/B) records influenced by the same watershed are reproducible. Furthermore, a strong Ba/Ca relationship was observed between two cores from distant watersheds, with baseline averages in agreement with modelled sediment runoff data. As humic acids behave conservatively in the water column, luminescence (G/B) data gave the highest regional correlations between cores, and showed the most consistent relationship with site specific modelled discharge. No statistical relationship was observed between cores in terms of interannual d18Osw and d13C, meaning corals were recording a localised signal at their respective sites, confounded by vital effects. Comparing proxy baseline averages and mean seasonal cycles provided a good overview of the runoff dynamics of the bay system.

title: NOAA/WDS Paleoclimatology - Washington Land, Greenland Late Pleistocene to Holocene 10Be Moraine Ages

description: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These moraine chronologies indicate a Little Ice Age advance of the ice sheet margin before ~0.3 ka and a possible equivalent advance of similar magnitude prior to ~2.8 ka. An early Holocene moraine at Humboldt Glacier was abandoned by 8.3 ± 1.7 ka and is contemporaneous with other moraines deposited along the entire western GIS margin. This widespread ice margin stability between ~9 and 8 ka indicates that while this margin was influenced by warming atmospheric temperatures during the early Holocene, the warming was likely overprinted with the effect of the abrupt climate cooling at 9.3 and 8.2 ka.

title: NOAA/WDS Paleoclimatology - East China Sea, offshore Yangtze River Valley d18O, d13C, and Mg/Ca Data and SST Reconstruction over the last 400,000 years

description: Speleothem CaCO3 d18O is a commonly employed paleomonsoon proxy. However, inferring local rainfall amount from speleothem d18O can be complicated due to changing source water d18O, temperature effects, and rainout over the moisture transport path. These complications are addressed using d18O of planktonic foraminiferal CaCO3, offshore from the Yangtze River Valley (YRV). The advantage is that the effects of global seawater d18O and local temperature changes can be quantitatively removed, yielding a record of local seawater d18O, a proxy that responds primarily to dilution by local precipitation and runoff. Whereas YRV speleothem d18O is dominated by precession-band (23-ky) cyclicity, local seawater d18O is dominated by eccentricity (100-ky) and obliquity (41-ky) cycles, with almost no precession-scale variance. These results, consistent with records outside the YRV, suggest that East Asian monsoon rainfall is more sensitive to greenhouse gas and high latitude ice sheet forcing than to direct insolation forcing.

title: NOAA/WDS Paleoclimatology - Gulf of Alaska authigenic and bulk sediment neodymium isotope compositions for the past 22,000 years

description: During the last deglaciation (19,000–9,000 years ago), atmospheric CO2 increased by about 80 ppm. Understanding the mechanisms responsible for this change is a central theme of palaeoclimatology, relevant for predicting future CO2 transfers in a warming world. Deglacial CO2 rise hypothetically tapped an accumulated deep Pacific carbon reservoir, but the processes remain elusive as they are underconstrained by existing tracers. Here we report high-resolution authigenic neodymium isotope data in North Pacific sediment cores and infer abyssal Pacific overturning weaker than today during the Last Glacial Maximum but intermittently stronger during steps of deglacial CO2 rise. Radiocarbon evidence suggestive of relatively ‘old’ deglacial deep Pacific water is reinterpreted here as an increase in preformed 14C age of subsurface waters sourced near Antarctica, consistent with movement of aged carbon out of the deep ocean and release of CO2 to the atmosphere during the abyssal flushing events. The timing of neodymium isotope changes suggests that deglacial acceleration of Pacific abyssal circulation tracked Southern Hemisphere warming, sea-ice retreat and increase of mean ocean temperature. The inferred magnitude of circulation changes is consistent with deep Pacific flushing as a significant, and perhaps dominant, control of the deglacial rise of atmospheric CO2.

title: NOAA/WDS Paleoclimatology - Secret Lake, NW Greenland Holocene Chironomid d18O and Inferred Temperature

description: Reconstructions of Holocene lake water isotopic composition based upon subfossil aquatic organic material offer new insights into Arctic climate. We present quantitative estimates of warmth during the Holocene Thermal Maximum in northwest Greenland, inferred from oxygen isotopes of chironomid head capsules and aquatic moss preserved in lake sediments. d18O values of chironomids from surface sediments of multiple Greenland lakes indicate that these subfossil remains record the d18O values of the lake water in which they grow. Our lake water d18O reconstruction is supported by downcore agreement with d18O values in aquatic moss and chironomid remains. d18O of both organic materials from Secret Lake decrease after 4 ka (ka = thousands of years ago) by 3 permil into the Neoglacial. We argue that lake water at Secret Lake primarily reflects precipitation d18O values, which is strongly correlated with air temperature in NW Greenland, and that this signal is biased towards summer and early autumn conditions. Other factors may have influenced Secret Lake d18O values through the Holocene, including evaporation of lake water and changing seasonality and source of precipitation. The maximum early Holocene summer and early autumn-biased temperature anomaly at Secret Lake is 2.5-4C warmer than present from 7.7 (the beginning of our record) to ~6 ka. The maximum late Holocene cold anomaly (which includes the Little Ice Age) is 1.5-3C colder than present. These ranges of possible temperature anomalies reflect uncertainty in the d18O - temperature relationship for precipitation at the study site through the Holocene.

title: NOAA/WDS Paleoclimatology - Eastern Equatorial Pacific d18O and d13C Data from the Last Glacial Maximum

description: The mean state and variability of the tropical Pacific is influenced by the depth of the thermocline. During the Last Glacial Maximum (~21,000 years ago), the zonal sea surface temperature gradient across the equatorial Pacific was reduced and productivity was generally lower than modern. To understand the thermocline depth's role in determining the Last Glacial Maximum tropical mean state, we reconstruct the upper ocean d18O profile from multiple species of planktic foraminifera. We synthesize existing records of surface and subsurface dwelling foraminifera to reconstruct the vertical d18O gradient throughout the eastern equatorial Pacific. We find the thermocline was deeper during the Last Glacial Maximum than the Holocene throughout the eastern equatorial Pacific region. The thermocline depth's role in the dynamic forcing of the cold tongue contributed to the reduced zonal SST gradient across the equatorial Pacific, decreased productivity, and presumably impacted El Niño-Southern Oscillation variability relative to the Holocene.

title: NOAA/WDS Paleoclimatology - Krusic - Mount Smolikas EHS03 - PIHE - ITRDB GREE015

description: We present a June-July drought reconstruction based on the standardized precipitation index (SPI) for the Balkan Peninsula over the period 730-2015 CE. The reconstruction is developed using a composite Pinus heldreichii tree-ring width chronology, from a high-elevation network of eight sites in the Pindus Mountains in northwest Greece, composed of living trees and relict wood. The dataset includes the ring width series of Europe's currently oldest known living tree, dendrochronologically dated to be more than 1075 years old. The spatial coverage of the reconstruction is improved by using an averaged gridded SPI data target derived from a response field that is located north of the study region. Justification for this approach includes the remoteness of instrumental data, the spatial variability of precipitation and synoptic scale circulation patterns. Over the past 1286 years, there have been 51 dry and 43 pluvial events. The driest year during the 1286-year-long period was 1660 and the wettest year was 1482. Comparison with shorter reconstructions and documentary evidence validates the new reconstruction, and provides additional insight into socioeconomic impacts and spatial patterns of extreme events. Fifty-nine of 72 previously undescribed extremes occurred prior to the 17th century. The new reconstruction reveals long-term changes in the number of extremes, including substantially fewer drought and pluvial events in the 20th century. Additional tests on the long-term effects of age structure, replication and covariance changes support the heteroscedastic nature of the reconstructed hydro-climatic extremes.

title: NOAA/WDS Paleoclimatology - Soreq Cave, Israel Speleothem Oxygen Isotope Data 33.8-4.4 ky BP

description: The combination of ion microprobe analysis of d18O and confocal laser fluorescent microscope imaging of annual growth bands in a Soreq Cave speleothem provides sub-annual-scale climate information between 34 and 4 ka. This high-resolution methodology is ideal both for comparing seasonal climate patterns across broad windows of time and examining rapid climate events, such as the Younger Dryas termination, in detail. The sub-annual d18O gradients we report represent a combination of seasonal variability in rainfall amount and air temperature. A distinct change in both the pattern of fluorescent banding and the gradient of d18O measured in situ across single, annual growth bands indicates a change in seasonal climate patterns of the Eastern Mediterranean region following Heinrich event 1 and again after the Younger Dryas. Throughout the Holocene, wet winters and dry summers characterized regional climate. During the Younger Dryas, we find that regional climate may have been more arid than in the Holocene, but the fluorescent banding pattern indicates that the supply of dripwater to the cave was more consistent year-round. We suggest that a reduced gradient of seasonal precipitation, occasional snowfall, and vegetation differences may have all contributed to the isotope and fluorescent banding patterns observed during Heinrich event 1 and the last glacial stadial. Detailed investigation of the Younger Dryas termination reveals a rapid onset of regional environmental change. Fluorescent band counting indicates that the Younger Dryas termination, as recorded by rainfall in the Eastern Mediterranean, spanned a minimum of 12 years.

title: NOAA/WDS Paleoclimatology - Southeastern Alaska Yellow-Cedar Decline Data

description: Decline of yellow-cedar (Chamaecyparis nootkatensis ((D. Don) Spach) has occurred on 200 000 ha of temperate rainforests across southeastern Alaska. Because declining forests appeared soon after the Little Ice Age and are limited mostly to low elevations (whereas higher elevation forests remain healthy), recent studies have hypothesized a climatic mechanism involving early dehardening, reduced snowpack, and freezing injury. This hypothesis assumes that a specific suite of microclimatic conditions occurs during late winter and declining cedar populations across the region have responded similarly to these conditions. Based on the first geographically extensive tree ring chronologies constructed for southeastern Alaska, we tested these assumptions by investigating regional climatic trends and the growth responses of declining cedar populations to this climatic variation. Warming winter trends were observed for southeastern Alaska, resulting in potentially injurious conditions for yellow-cedar due to reduced snowfall and frequent occurrence of severe thaw-freeze events. Declining cedar forests shared a common regional chronology for which late-winter weather was the best predictor of annual growth of surviving trees. Overall, our findings verify the influence of elevational gradients of temperature and snow cover on exposure to climatic stressors, support the climatic hypothesis across large spatial and temporal scales, and suggest cedar decline may expand with continued warming.
