title: NOAA/WDS Paleoclimatology - Birch - Cedar Breaks National Monument - PIFL - ITRDB UT547

description: Tree rings provide an invaluable long-term record for understanding how climate and other drivers shape tree growth and forest productivity. However, conventional tree-ring analysis methods were not designed to simultaneously test effects of climate, tree size, and other drivers on individual growth. This has limited the potential to test ecologically relevant hypotheses on tree growth sensitivity to environmental drivers and their interactions with tree size. Here, we develop and apply a new method to simultaneously model nonlinear effects of primary climate drivers, reconstructed tree diameter at breast height (DBH), and calendar year in generalized least squares models that account for the temporal autocorrelation inherent to each individual tree's growth. We analyze data from 3811 trees representing 40 species at 10 globally distributed sites, showing that precipitation, temperature, DBH, and calendar year have additively, and often interactively, influenced annual growth over the past 120 years. Growth responses were predominantly positive to precipitation (usually over >=3-month seasonal windows) and negative to temperature (usually maximum temperature, over <=3-month seasonal windows), with concave-down responses in 63% of relationships. Climate sensitivity commonly varied with DBH (45% of cases tested), with larger trees usually more sensitive. Trends in ring width at small DBH were linked to the light environment under which trees established, but basal area or biomass increments consistently reached maxima at intermediate DBH. Accounting for climate and DBH, growth rate declined over time for 92% of species in secondary or disturbed stands, whereas growth trends were mixed in older forests. These trends were largely attributable to stand dynamics as cohorts and stands age, which remain challenging to disentangle from global change drivers. By providing a parsimonious approach for characterizing multiple interacting drivers of tree growth, our method reveals a more complete picture of the factors influencing growth than has previously been possible.

title: NOAA/WDS Paleoclimatology - Earth Orbital 100 Million Year Precession and Tilt Solutions

description: Pre-Pleistocene age models used in paleoceanography and paleoclimatology often rely on the imprint of astronomically calculated cycles of eccentricity and other solar system frequencies in sedimentary records (405, 173, and 100kyr). However, use of obliquity and precession cycles (at present ~41 and ~20 kyr) remains challenging for these periods, mostly due to past changes in Earth's dynamical ellipticity (Ed, gravitational shape) and tidal dissipation (Td, slowdown of Earth's rotation), which affect the astronomical calculations. Here we present a dating method for deep-time records by integrating Ed and Td into astrochronology. The key to our approach is the combination of constraints on Td (and thus indirectly on Ed) with age model optimization based on solar system frequencies, plus tuning to obliquity/precession frequencies, while varying Td and Ed. Importantly, we target deep-time intervals where Td\ shows significant effects but high-quality sedimentary records are available (early Cenozoic). We include a quickstart guide to our approach and make our code and pre-computed solutions freely available for users. To demonstrate the practical utility of our approach, we apply our tool to two case studies using deep-sea records from the early and middle Eocene. Our results confirm very accurate chronologies of sedimentary records from the early Eocene (~56-54Ma) but suggest significant improvement for the middle Eocene (~40-39Ma). For the early Eocene, our method provides absolute geologic ages with an estimated uncertainty of +-20 to 40kyr, which is smaller than or equal to typical uncertainties from recent radiometric Ar/Ar dating.

title: NOAA/WDS Paleoclimatology - Lake Kail, Guatemala 6,000 Year Stable Isotope and Physical Properties Data

description: Long-term perspectives on past hydroclimate variability provide context for evaluating the potential future impacts of changes in Northern Hemisphere temperatures and oceanic-atmospheric circulation on the timing and distribution of precipitation in Central America. Here we use the isotopic composition of fine-grained (< 63 um), endogenic CaCO3 (d18Ocalcite and d13Ccalcite) from Lake Kail, located in the western highlands of Guatemala, to infer multi-decadal to multi-centennial-scale variability in the balance between precipitation and evaporation (P/E) over the last ~6000 years. The sediment age model is based on 210Pb and 41 14C ages, with chronological uncertainty estimated using Bayesian methods. A model that couples lake hydrology and isotope mass balance is applied to characterize the isotopic responses of lake water and calcite to changes in drought-controlling climate variables such as precipitation, temperature and relative humidity. The d18Ocalcite variations indicate intermediate-to-dry P/E conditions during the late-middle Holocene from ~6000 to ~4100 cal yr BP. There was then a shift to drier conditions at the start of the late Holocene until ~3050 cal yr BP, followed by a trend to wetter conditions until ~1500 cal yr BP. The most recent ~1500 years is characterized by high and relatively stable P/E, with particularly wet intervals from ~1500 to 1170 cal yr BP and from 470 to 260 cal yr BP. Comparisons of the Lake Kail d18Ocalcite record with Central American/circum-Caribbean proxy datasets spanning the late-middle and late Holocene indicate northern tropical hydroclimate changes were highly variable across space and time and were likely driven by regional oceanic-atmospheric responses with a secondary influence by insolation forcing.

title: NOAA/WDS Paleoclimatology - Jevsenak - Mlace - QURO - ITRDB SLOV004

description: Quercus robur dieback remained not completely explained even though numerous papers have been focused on this problem. In the future, more severe and unpredictable climate conditions are expected which may additionally accelerate oaks dieback. It is essential to understand the relationship between climate and tree growth to make proper management measures. Declining and vital group of pedunculate oaks from two sites in Slovenia were compared. Comparing to the group of vital trees, group of declining trees showed superior growth in earlier stage of development which may contribute to their higher vulnerability to environmental changes. Dieback of declining trees was at first visible in ring width (RW) and latewood width (LW). Only in 1995, when final stage of mortality started, smaller conductive elements were observed. Relationship between climate and analyzed parameters (ring width, earlywood width, latewood width, total vessel area, mean vessel area and maximal vessel area) was related to site specifications and was therefore considerable different for both groups. Vital trees from slightly hilly location were responding to the mean temperatures and sum of precipitations. Declining group from lowlands in Cigonca was corresponding only to the mean monthly temperatures.

title: NOAA/WDS Paleoclimatology - Brahmaputra River 700 Year Monsoon Season Streamflow Reconstruction

description: The lower Brahmaputra River in Bangladesh and Northeast India often floods during the monsoon season, with catastrophic consequences for people throughout the region. While most climate models predict an intensified monsoon and increase in flood risk with warming, robust baseline estimates of natural climate variability in the basin are limited by the short observational record. Here we use a new seven-century (1309-2004 C.E) tree-ring reconstruction of monsoon season Brahmaputra discharge to demonstrate that the early instrumental period (1956-1986 C.E.) ranks amongst the driest of the past seven centuries (13th percentile). Further, flood hazard inferred from the recurrence frequency of high discharge years is severely underestimated by 24-38% in the instrumental record compared to previous centuries and climate model projections. A focus on only recent observations will therefore be insufficient to accurately characterise flood hazard risk in the region, both in the context of natural variability and climate change.

title: NOAA/WDS Paleoclimatology - South African Summer Rainfall Zone Air Temperature Reconstructions during the Holocene

description: Late Quaternary climate variability in the southern African subtropics is still only poorly resolved, with significant complexity and apparent contradictions in the regional dataset. To more effectively interpret and synthesize key regional records, we reanalysed the data from 13 pollen sequences from the summer rainfall zone of South Africa spanning the last 45,000 years, obtaining directly comparable quantitative reconstructions of mean annual temperature and summer rainfall. Temperature reconstructions from across the region provide consistent results, with all sites reflecting trends observed in southwest Indian Ocean sea-surface temperatures in the adjacent Mozambique Channel. Precipitation reconstructions are more heterogeneous, with two distinct subregions being identified. In the northeast, long-term trends in precipitation are determined by sea-surface and continental temperature trends, revealing a positive relationship between temperature and rainfall. This long-term pattern appears to be primarily driven by high northern latitude mechanisms, with direct local insolation being subordinate. Their relative impact reversed during terminal glacial period/early Holocene, at which time direct insolation forcing became the main driver of rainfall variability. Further south, in central South Africa, precipitation variability appears also to be influenced by the latitudinal position of the Southern Hemisphere westerlies, which combine with tropical flow to create tropical-temperate trough, advecting moisture into the interior. In this region, periods of maximum precipitation coincide with periods of elevated SSTs and equatorward expansions of the westerly storm track. This study allows for a fully constrained understanding of climate dynamics along the eastern African margin for the last 45,000 years, linking dynamics to drivers and describing how the climate systems evolved across the last glacial–interglacial transition.

title: NOAA/WDS Paleoclimatology - Larson - Dry Dog Ranch - QUAL - ITRDB WI027

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.
