title: NOAA/WDS Paleoclimatology - Tumajer - Zbytka - QURO - ITRDB CZEC034

description: Drought events and the overuse of groundwater for water supply can cause significant declines of groundwater levels in naturally poorly drained forest stands. However, the documented growth reactions of trees to declines in groundwater level vary a lot and range from positive because of increased soil aeration to strongly negative because of drought stress. We analysed changes in tree-ring width and earlywood average vessel lumen area of Quercus robur from sites above an artesian aquifer, whose groundwater level declined in the late 1980s by about 5 m due to water pumping. Because we expected different responses of individual trees due to local microtopography and fine root distribution, we performed both site-level and tree-level analyses. Our results show that the site-level response of tree growth to groundwater-level pumping was not uniform. Individual trees were clustered into groups of drought-limited and water abundance-limited individuals. The response of trees to groundwater pumping differed between clusters - drought-sensitive trees responded negatively, whereas the growth of trees limited by water abundance remained stable or slightly increased. Inter-series correlation of drought-limited trees significantly increased in the period with the lowest groundwater level. In contrast to tree-ring widths, earlywood vessel lumen area series contained common temperature signal, with no imprint of groundwater-level alteration. Our results indicate that poorly drained forest ecosystems are characterized by a significantly individualistic response of radial growth to groundwater-level alteration. These individualistic responses could be, however, overshadowed in stand-level average tree-ring width chronologies.

title: NOAA/WDS Paleoclimatology - Northern Great Barrier Reef 1972-2008 Porites Data and SST Reconstructions

description: The remoteness of the northern Great Barrier Reef makes observations of environmental change and coral health sparse, but provides opportunities for paleoclimate and paleoecology proxies to contribute new insights into coral health in a changing climate. These proxies include geochemical measures (d18O, d13C, and Sr/Ca) that track sea surface temperature (SST), salinity, and physiological processes; luminescence, which records freshwater input; and annual growth parameters (density, extension, and calcification). Merging these approaches provides insight into the historical role of environmental variability in coral health. This study uses Porites spp. corals from five sites on the northern Great Barrier Reef (12-13.5S) to produce combined monthly resolved records of geochemistry, growth banding, and luminescence between 1972 and 2008. We demonstrate that SST reconstructed from Sr/Ca accurately captures Indo-Pacific Warm Pool variability, and hydrological proxies (luminescence and seawater d18O) accurately reconstruct summer rainfall and river discharge in nearshore corals. Concurrent Sr/Ca minima and density and luminescence peaks from two sites demonstrate that high-density bands are generally formed during summer at these sites, which aids the development of future coral paleoclimate and paleoecology chronologies. Regional hydrological proxies showed more consistent responses to El Nino-Southern Oscillation (ENSO) events than SST proxies, in agreement with instrumental data. Because these corals, like instrumental records, show no consistently large ENSO heat extremes, we find no consistent growth anomalies during historical ENSO events. Our results highlight the unusual nature of recent widespread and severe coral bleaching and establish groundwork for exploring the response of northern GBR corals to past climate variations.

title: NOAA/WDS Paleoclimatology - Equatorial Pacific One Million Year Trace Metal Data

description: The deep ocean has long been recognized as the reservoir that stores the carbon dioxide (CO2) removed from the atmosphere during Pleistocene glacial periods. The removal of glacial atmospheric CO2 into the ocean is likely modulated by changes in the degree of utilization of macronutrients at the sea surface and enhanced storage of respired CO2 in the deep ocean, known as enhanced efficiency of the biological pump. Enhanced biological pump efficiency during glacial periods is most easily documented in the deep ocean using proxies for oxygen concentrations, which are directly linked to respiratory CO2 levels. We document the enhanced storage of respired CO2 during the Last Glacial Maximum (LGM) in the Pacific Southern Ocean and deepest Equatorial Pacific using records of deglacial authigenic manganese, which form as relict peaks during increases in bottom water oxygen concentration. These peaks are found at depths and regions where other oxygenation histories have been ambiguous, due to diagenetic alteration of authigenic uranium, another proxy for bottom water oxygen. Our results require that the entirety of the abyssal Pacific below approximately 1000m was enriched in respired CO2 and depleted in oxygen during the LGM. The presence of authigenic Mn enrichment in the deep Equatorial Pacific for each of the last five deglaciations suggests that the storage of respired CO2 in the deep ocean is a ubiquitous feature of late-Pleistocene ice ages.

title: NOAA/WDS Paleoclimatology - Hughes - Deer Creek - SEGI - ITRDB CA725

description: The first dendroclimatic reconstruction of May 1 snow water equivalent (SWE) was developed from a Sequoiadendron giganteum regional tree-ring chronology network of 23 sites in central California for the period 90-2012 CE. The reconstruction is based on a significant relationship between May 1 SWE and tree-ring growth and shows climate variability from interannual to intercentennial time scales. A regression-based reconstruction equation explains up to 55% of the variance of SWE for 1940-2012. Split-sample validation supports our use of a reconstruction model based on the full period of reliable observational data (1940-2012). Thresholds for May 1 SWE low (15 percentile) and high (80 percentile) years were selected based on the exploratory scatterplots relationship between observed and reconstructed data for the period 1940-2012. The longest period of consecutive low-SWE years in the reconstruction is 2 years and the frequency of the lowest SWE years is highest during the period 710-809 CE. The longest high-SWE period, defined by consecutive wet years, is 3 years (558-560 CE). SWE and its reconstruction positively correlate with northeastern Pacific sea surface temperatures, the low-frequency variability of which may provide some predictive ability. Ultimately, the instrumental record and reconstruction suggest that unlike other sites in the region, twentieth century SWE variability in these Sequoia groves has remained within historical boundaries and relatively buffered from extremes and severe declines, though this is likely to change in coming decades with potentially negative effects on water availability for these trees.

title: NOAA/WDS Paleoclimatology - GISP2 and WAIS Divide Ice Cores 60,000 Year Surface Temperature Reconstructions

description: Ice cores provide detailed records of past climate change. Water stable isotopes are the most commonly used ice core climate proxy, but their quantitative interpretation remains challenging. Here I argue that the gas age-ice age difference (Dage) is a powerful proxy for past surface temperature. An analytical framework is derived that directly links past temperature to firn properties that can be reliably reconstructed (Dage, lock-in depth). The framework is calibrated using both present-day spatial patterns and last glacial maximum temperatures reconstructed via borehole thermometry. The usefulness of the method is demonstrated using three case studies from Greenland and Antarctic ice cores. The calibration suggests that several firn densification models, with the possible exception of the Herron-Langway model, have insufficient sensitivity to accumulation rates. This low sensitivity, in combination with large amplitude temperature forcing, can explain historical difficulties of densification models in simulating ice age firn thickness in East Antarctica.

title: NOAA/WDS Paleoclimatology - Northwestern Australia Mio-Pliocene Polycyclic Aromatic Hydrocarbon (PAH) Data

description: C4 grasslands proliferated later in Australia than they did on other continents (~ 3.5 Ma versus 10 to 5 Ma). It remains unclear whether this delay reflects differences in climate conditions or ecological feedbacks, such as fire, that promote C4 ecosystems. Here, we evaluated these factors using terrestrial biomarkers from marine sediments off western Australia. Fire-derived polycyclic aromatic hydrocarbons (PAH) indicate fire ecology did not substantially change during or following C4 expansion. The presence of fire-adapted C3 woody vegetation likely diminished the role of fire and delayed C4 expansion until it was prompted by climate drying between 3.5 to 3.0 Ma. At the same time, mass accumulation rates of weathered PAHs increased 100-fold, which indicates a significant loss of soil carbon accompanied this ecosystem shift. The tight couplings between hydroclimate and carbon storage altered boundary conditions for Australian ecosystems, and similar abrupt behavior may shape environmental responses to climate change.

title: NOAA/WDS Paleoclimatology - Fennoscandia Air Temperature and Growing Degree Days Reconstructions during the Holocene

description: With global warming, the distribution of warmth through the year is likely to change in the future and comparable changes may have occurred over the course of the Holocene. Its effect on vegetation composition and species distribution can be compared to that of a continental versus an oceanic climate. The distribution of five major tree species along a continentality gradient was studied in Fennoscandia based on distribution maps and on their proportions of pollen in surface-sediment samples. Both analyses indicate that the five arboreal species show similar patterns of response to a continentality index in the order Ulmus glabra, Corylus avellana, Quercus robur, Tilia cordata, and Picea abies from the most oceanic to most continental. Continentality, growing degree days above 5 °C, and January temperature were reconstructed quantitatively from four pollen diagrams using transfer functions based on a combined Fennoscandian pollen surface-sample data-set. Quantitative reconstructions indicate that the climate in Fennoscandia has become increasingly more continental over the last 7000 years, and this is largely an effect of winter cooling. Early Holocene vegetation composition has poor analogues to the present vegetation in Fennoscandia, which hampers quantitative reconstructions. Qualitative reconstructions suggest that the early Holocene in Fennoscandia was the most oceanic period, but probably with a high variability in temperature.
