title: NOAA/WDS Paleoclimatology - Myrmidon Reef, Great Barrier Reef, Isopora palifera trace elements 2001-2013 CE

description: Studies on the growth response of corals to changing climate have largely focused on long-lived corals with relatively distinct density bands such as massive Porites corals. Little is known about the climatic response of other more abundant growth forms, such as branching Acropora corals, largely because of the absence of a clear annual density banding pattern. Using a combination of X-radiography, gamma densitometry, Sr/Ca analysis, and Uranium–Thorium (U-Th) dating, we quantified patterns of annual growth in the robust branching coral Isopora palifera from the central Great Barrier Reef (GBR), Australia (18°16'S 147°22'E) collected in May 2013. While visual analysis of the positive X-radiographs revealed alternating patterns of high- and low-density bands along the central growth axis, gamma-densitometry analysis suggests that these bands do not exhibit a clear annual cycle. In contrast, skeletal Sr/Ca ratios consistently revealed clear patterns of seasonality matching local sea surface temperatures (SST), and provided a growth chronology to calculate linear extension rate, skeletal density and calcification rate. Comparisons between SST-Sr/Ca calibrations derived from our I. palifera samples with (i) massive Porites from the same location and (ii) Isopora spp. from the GBR and Papua New Guinea revealed significant differences of up to 3.5 °C, implying palaeoclimate reconstructions should use site-specific and species-specific Sr/Ca-SST calibrations. Our approach provides a robust method for assessing changes in growth for a common Indo-Pacific branching coral, and provides a valuable framework for quantifying past and future changes in skeletal growth in response to climate change.

title: NOAA/WDS Paleoclimatology - Touchan - Djeniene - PIHA - ITRDB DZA014

description: The first large-scale network of tree-ring chronologies from the western Mediterranean (WM; 32°N–43°N, 10°W–17°E) is described and analyzed to identify the seasonal climatic signal in indices of annual ring width. Correlation and rotated empirical orthogonal function analyses are applied to 85 tree-ring series and corresponding gridded climate data to assess the climate signal embedded in the network. Chronologies range in length from 80 to 1129 years. Monthly correlations and partial correlations show overall positive associations for Pinus halepensis (PIHA) and Cedrus atlantica (CDAT) with winter (December–February) and spring (March–May) precipitation across this network. In both seasons, the precipitation correlation with PIHA is stronger, while CDAT chronologies tend to be longer. A combination of positive correlations between growth and winter–summer precipitation and negative partial correlations with growing season temperatures suggests that chronologies in at least part of the network reflect soil moisture and the integrated effects of precipitation and evapotranspiration signal. The range of climate response observed across this network reflects a combination of both species and geographic influences. Western Moroccan chronologies have the strongest association with the North Atlantic Oscillation.

title: NOAA/WDS Paleoclimatology - Guliya Ice Cap, China d18O, d-excess, ammonium, Dust Data covering the last 41ka

description: The influences on climate in the Northwest Tibetan Plateau (NwTP) have changed on millennial to precessional timescales and have been dependent on the size of the Northern Hemisphere ice sheets, Northern Hemisphere summer insolation, and the migration of the Intertropical Convergence Zone (ITCZ). All these influences control the position and intensity of the westerlies over Central Asia and the Tibetan Plateau and of the Asian Monsoon over South Asia. The top 187.4 meters of a 309.7-meter ice core (2015GP) drilled on the plateau of the Guliya ice cap contains a 41-kyr climate history of the NwTP, a region where information on past climate and environment is limited. The oxygen isotope ratio (d18O), and ammonium (NH4+) and dust concentration records from 2015GP show that during the glacial (41 to 17.5 ka BP) temperature and precipitation in the NwTP were primarily influenced on the precessional timescale by summer insolation, while at millennial resolution the climate was linked to the North Atlantic temperature via the westerlies. During the deglaciation (17.5 to 12 ka BP) summer insolation remained an important temperature forcing, but the influence of the North Atlantic climate on the NwTP climate weakened as the westerlies shifted northward. The Guliya Holocene d18O record shows that NwTP climate was no longer in phase with decreasing summer insolation or with North Atlantic climate, perhaps as the moisture source and pathways were more determinative factors in isotopic fractionation than temperature, and/or incoming solar radiation (insolation) forcing was replaced by rising greenhouse gas concentrations as the primary driver of warming in NwTP.

title: NOAA/WDS Paleoclimatology - Dewar fire data from Valle Toledo, Jemez Mountains - IMPD USVTW001

description: Objectives
We aimed to demonstrate the efficacy of using grassland-forest ecotone trees to reconstruct spatial and temporal properties of the historical fire regime in a complex landscape of montane forests and adjacent grasslands.

Methods
We sampled and crossdated fire-scarred trees along ecotones and compared variations in historical fire occurrence within and among nine adjoining valle basins in a 10,158 ha landscape. We analyzed fire year extensiveness, climate regulation, and the occurrence of consecutive fire years.

Results
The resulting tree-ring record covers 1240-2005 AD, with 296 trees recording 125 replicated fire years during the analysis period 1601-1902 AD. Mean fire intervals for all events recorded on two or more trees ranged from 4.7 to 13.6 years in individual valles, and a mean of 2.4±1.7 (SD) years at the landscape scale. Between 1660 and 1902, extensive fires occurring in six or more valles occurred 15 times, on average at ~17-year intervals; 29 moderately widespread fires (3–5 valles) occurred during this period, at 8.7 year intervals on average. Widespread events occurred in years with a significantly lower Palmer Drought Severity Index (PDSI) preceded by years of significantly positive PDSI, indicating conditions favorable for fine fuel production. Spatial reconstruction of fire extent revealed multiple occurrences of consecutive-year fires burning non-overlapping areas, associated with persistent low PDSI anomalies preceded by positive conditions in antecedent years.

Conclusions
A landscape spatiotemporal approach to reconstructing fire regimes of montane forest-grassland complexes provides a valuable baseline for guiding prescribed and natural fire management at large spatial scales.

title: NOAA/WDS Paleoclimatology - Wiles - Juneau Mountain Update - TSME - ITRDB AK204

description: Ring-width (RW) records from the Gulf of Alaska (GOA) have yielded a valuable long-term perspective for North Pacific changes on decadal to longer timescales in prior studies but contain a broad winter to late summer seasonal climate response. Similar to the highly climate-sensitive maximum latewood density (MXD) proxy, the blue intensity (BI) parameter has recently been shown to correlate well with year-to-year warm-season temperatures for a number of sites at northern latitudes. Since BI records are much less labour intensive and expensive to generate than MXD, such data hold great potential value for future tree-ring studies in the GOA and other regions in mid- to high latitudes. Here we explore the potential for improving tree-ring-based reconstructions using combinations of RW- and BI-related parameters (latewood BI and delta BI) from an experimental subset of samples at eight mountain hemlock (Tsuga mertensiana) sites along the GOA. This is the first study for the hemlock genus using BI data. We find that using either inverted latewood BI (LWBinv) or delta BI (DB) can improve the amount of explained temperature variance by > 10 % compared to RW alone, although the optimal target season shrinks to June–September, which may have implications for studying ocean–atmosphere variability in the region. One challenge in building these BI records is that resin extraction did not remove colour differences between the heartwood and sapwood; thus, long term trend biases, expressed as relatively warm temperatures in the 18th century, were noted when using the LWBinv data. Using DB appeared to overcome these trend biases, resulting in a reconstruction expressing 18th–19th century temperatures ca. 0.5 °C cooler than the 20th–21st centuries. This cool period agrees well with previous dendroclimatic studies and the glacial advance record in the region. Continuing BI measurement in the GOA region must focus on sampling and measuring more trees per site (> 20) and compiling more sites to overcome site-specific factors affecting climate response and using subfossil material to extend the record. Although LWBinv captures the inter-annual climate signal more strongly than DB, DB appears to better capture long-term secular trends that agree with other proxy archives in the region. Great care is needed, however, when implementing different detrending options and more experimentation is necessary to assess the utility of DB for different conifer species around the Northern Hemisphere.
