title: NOAA/WDS Paleoclimatology - Gulf of Oman M5-422 Holocene Eolian Mineral Dust Data

description: The Akkadian empire ruled Mesopotamia from the headwaters of the Tigris-Euphrates Rivers to the Persian Gulf during the late third millennium B.C. Archeological evidence has shown that this highly developed civilization collapsed abruptly near 4170 ± 150 calendar yr B.P., perhaps related to a shift to more arid conditions. Detailed paleoclimate records to test this assertion from Mesopotamia are rare, but changes in regional aridity are preserved in adjacent ocean basins. We document Holocene changes in regional aridity using mineralogic and geochemical analyses of a marine sediment core from the Gulf of Oman, which is directly downwind of Mesopotamian dust source areas and archeological sites. Our results document a very abrupt increase in eolian dust and Mesopotamian aridity, accelerator mass spectrometer radiocarbon dated to 4025 ± 125 calendar yr B.P., which persisted for ~300 yr. Radiogenic (Nd and Sr) isotope analyses confirm that the observed increase in mineral dust was derived from Mesopotamian source areas. Geochemical correlation of volcanic ash shards between the archeological site and marine sediment record establishes a direct temporal link between Mesopotamian aridification and social collapse, implicating a sudden shift to more arid conditions as a key factor contributing to the collapse of the Akkadian empire.
description: Core M5-422 from the Gulf of Oman was continuously subsampled at 2 cm intervals to reconstruct a marine sediment record of 
Holocene variations in regional aridity.  Temporal resolution averages about 100 yr.  A dramatic mid-Holocene increase in eolian dolomite and calcite deposition occurred between 70 and 56 cm in the core, corresponding to an ~400 yr period spanning 4025–3625 B.P.  

CaCO3 percent was measured by coulometry and the dolomite percent was measured by quantitative X-ray diffraction using calibrated equations derived from XRD analyses of known mineral admixture sample standards.

title: NOAA/WDS Paleoclimatology - Touchan - Eşek Meydanı - PISY - ITRDB TUR070

description: The first large-scale network of 79 tree-ring chronologies in the Eastern Mediterranean and Near East (EMNE; 33°N–42°N, 21°E–43°E) is described and analyzed to identify the seasonal climatic signal in indices of annual ring width. Correlation analysis and cluster analysis are applied to tree-ring data and gridded climate data to assess the climate signal embedded in the network in preparation for climate field reconstructions and formal proxy/model intercomparison experiments. The lengths of the 79 combined chronologies range from 89 to 990 years. The monthly correlations and partial correlations reveal a pervasive positive association with May, June, and sometimes July precipitation, positive correlations with winter and spring (December through April) temperatures, and negative relationships with May through July temperature, although as expected, there are site-to-site exceptions to these general patterns. Cluster analysis suggests three groups of sites based on their association with climate. The chronologies for the EMNE have coherent seasonal precipitation and temperature signals across a fairly broad geographical domain. The predominant signal is a positive growth response to May–June precipitation. Collectively, the findings suggest that the network can be exploited to develop season-specific field reconstructions of precipitation and drought history in the EMNE.

title: NOAA/WDS Paleoclimatology - Schneider - Berlin Teufelssee dek01 - QURO - ITRDB DEU303

description: Using dendroclimatological techniques this study investigates whether inner city tree-ring width (TRW) chronologies from eight tree species (ash, beech, fir, larch, lime, sessile and pedunculate oak, and pine) are suitable to examine the urban heat island of Berlin, Germany. Climate-growth relationships were analyzed for 18 sites along a gradient of increasing urbanization covering Berlin and surrounding rural areas. As a proxy for defining urban heat island intensities at each site, we applied urbanization parameters such as building fraction, impervious surfaces, and green areas. The response of TRW to monthly and seasonal air temperature, precipitation, aridity, and daily air-temperature ranges were used to identify climate-growth relationships. Trees from urban sites were found to be more sensitive to climate compared to trees in the surrounding hinterland. Ring width of the deciduous species, especially ash, beech, and oak, showed a high sensitivity to summer heat and drought at urban locations (summer signal), whereas conifer species were found suitable for the analysis of the urban heat island in late winter and early spring (winter signal). The summer and winter signals were strongest in tree-ring chronologies when the urban heat island intensities were based on an area of about 200 m to 3000 m centered over the tree locations, and thus reflect the urban climate at the scale of city quarters. For the summer signal, the sensitivity of deciduous tree species to climate increased with urbanity. These results indicate that urban trees can be used for climate response analyses and open new pathways to trace the evolution of urban climate change and more specifically the urban heat island, both in time and space.

title: NOAA/WDS Paleoclimatology - Tongue of the Ocean, Pear Tree Bottom - Sclerosponge Minor Element Data

description: The trace and minor element composition have been investigated in the accretionary skeletons of two specimens of the Caribbean sclerosponge species, Ceratoporella nicholsoni; one from Tongue of the Ocean, Bahamas (TOTO), and the other from Pear Tree Bottom, Jamaica (PTB). Both sclerosponges were analyzed at high resolution using laser ablation ICP-MS (LA-ICP-MS) and verified using wet chemical methods (ICP-OES). The shallow PTB sclerosponge (25 m) was analyzed for a short, temperature-calibrated record of trace and minor elements while the TOTO sclerosponge (146 m) was analyzed for a century long record from subsurface waters. The resulting Ba/Ca, Mg/Ca, Pb/Ca, and U/Ca ratios were compared with Sr/Ca ratios, which have been shown to reliably record seasonal-scale temperature change in sclerosponges, close to equilibrium precipitation of inorganic aragonite. Sclerosponge aragonite incorporates minor and trace elements according to general mineralogic constraints with less ""vital"" effects than other calcium carbonate secreting organisms. This is perhaps most obvious in the behavior of Mg/Ca ratios which show an inverse correlation to temperature unlike any other calcite or aragonite organism, despite having Mg concentrations (~1 mmol/mol) within published estimates of equilibrium aragonite. Ratios of Mg/Ca and Ba/Ca show a strong positive correlation despite large differences in ionic radii and U/Ca values (~3.15 Mmol/mol) are 2.5× higher in sclerosponge aragonite than in aragonite from corals, supporting earlier work. Ratios of U/Ca show an insignificant correlation with temperature-dependent Sr/Ca ratios (r2 = 0.05), supporting existing theories that temperature signals recorded by U/Ca ratios can be convolved with pH, [CO3-2], and phosphate signals. Differences between sclerosponge aragonite and other calcium carbonate arising from siliceous spicule contamination are unlikely because of the small mole percent of silicon in the aragonite. Small differences between the two sclerosponges were noticed in Pb/Ca and Sr/Ca because of the average ages of the sampled material and average temperatures of the ambient environment, respectively. Anomalies between LA-ICP-MS and ICP-OES were noticed in measurements of Ba/Ca and Pb/Ca due to standardization differences for LA-ICP-MS (Ba/Ca) and measurements close to the instrument detection limits of Pb (ICP-OES).
