title: NOAA/WDS Paleoclimatology - Skala Marion Cave Geochemical Data from 5500 to 1500 Cal Yr BP

description: The climatic transitional zone of the northern Aegean Sea, potentially affected by different weather systems in the past, was the center of developed human societies that experienced rise and fall in the context of a few centuries. Interconnections of human occupation and climate shifts from the Bronze Age until the demise of the Roman Empire are investigated, based on the first high resolution isotope record of a stalagmite from northern Aegean region (Skala Marion Cave, Thassos Island, Greece). Fourteen U/Th dated layers tune precisely the isotope signal and provide distinct information of climate deterioration to drier conditions at 3900–3700, 3600–3400, 2600–2000 and after 1500 yr BP. The intensity of the impact of these deteriorations on human societies is evaluated against archaeological data and in respect to the tolerance of the societies in the Bronze Age versus the Iron Age. Finally, it is evident that downscaling to local environments result in time discrepancies between the records which could only be addressed when the most robust and large amplitude oscillations have been identified.

title: NOAA/WDS Paleoclimatology - Dim Cave Geochemical Data from 132200 to 128300 Cal Yr BP

description: A stalagmite from Dim Cave in southern Turkey contains a climate record documenting rapid and significant changes in amounts of precipitation between ~132 ka and ~128 ka, during the penultimate glacial – interglacial transition. Some U–Th dates have been compromised by carbonate dissolution but rigorous selection and tuning to δ18O records from other speleothems has generated a robust age model. Growth rate was initially very slow but a rapid increase at ~129 ka was accompanied by strong negative trends in δ18O and δ13C, a combination implying the onset of much wetter conditions. Isotopic values at ~129 ka suggest that groundwater recharge rates and biogenic activity in the soil zone exceeded those of the early Holocene. A significant isotopic enrichment event at ~128 ka, during which there was alternating aragonite and calcite deposition, documents a strong drying event with a duration of ~200 years. A concurrent decrease in 87Sr/86Sr ratios indicates increased groundwater residence times and the cumulative evidence suggests amounts of rainfall fell from well above to slightly below present-day levels. Similar δ18O enrichment events are present in coeval speleothem records from southwest France and the Northern Alps, and these, together with pollen evidence from Italy, Greece and the Iberian margin of drier conditions at this time, imply that a climate anomaly extended across the northern Mediterranean borderlands. The timing, duration and structure of this episode are consistent with marine evidence of strong North Atlantic cooling early in the last interglacial and there is a resemblance to the Holocene 8.2 ka event recorded globally in many proxy-climate archives.

Notes from the SISAL database: Vegetation: Mainly coniferous woodland (red pine and maquis) with bushes and a sparse ground cover. \\ Dim-E3, Dim-E4, Dim-E5 (SISAL entity_id = 168, 169, 170): The Sr isotope samples were matched with the stable isotope measurements based on the interpolated age rather then the depth values. Entity Dim-E3 (entity_id = 168): There is interp_age inversion between the following depth_samples: [99.5 and 103.5]. Possible short hiatuses between depths [22.5 & 26.0, 36.5 & 37.5, 132.5 & 133 and 254 & 257.5 mm] with corresponding ages ~23, 33, 60, and 77kyr respectively. Dim1 (entity_id = 754): The epikarst varies in thickness from a few metres to several tens of metres. For Sr isotopes, nine analyses of the NBS987 standard gave a value of 0.710251 ± 0.000003 (4.9 ppm, 1- sigma) at the time of analysis.There is a discrepancy between the mineraology of the date samples and the stable isotope samples. In the case of the latter between 88-98mm from the top is indicated as aragonite, while there are more aragonite samples at more shallow depths in the case of the date samples.

title: NOAA/WDS Paleoclimatology - Grotta di Ernesto Geochemical Data from 8000 to 2500 Cal Yr BP

description: Here we present high-resolution stable isotope and lamina thickness profiles as well as radiocarbon data for the Holocene stalagmite ER 76 from Grotta di Ernesto (north-eastern Italy), which was dated by combined U-series dating and lamina counting. ER 76 grew between 8 ka (thousands of years before 2000 AD) and today, with a hiatus from 2.6 to 0.4 ka.

Data from nine meteorological stations in Trentino show a significant influence of the North Atlantic Oscillation (NAO) on winter temperature and precipitation in the cave region. Spectral analysis of the stable isotope signals of ER 76 reveals significant peaks at periods of 110, 60–70, 40–50, 32–37 and around 25 a. Except for the cycle between 32 and 37 a all periodicities have corresponding peaks in power spectra of solar variability, and the 25-a cycle may correspond to NAO variability. This suggests that climate variability in northern Italy was influenced by both solar activity and the NAO during the Holocene.

Six periods of warm winter climate in the cave region were identified. These are centred at 7.9, 7.4, 6.5, 5.5, 4.9 and 3.7 ka, and their duration ranges from 100 to 400 a. The two oldest warm phases coincide with the deposition of sapropel S1 in the Mediterranean Sea indicating that the climate in the cave region was influenced by this prominent pluvial phase in the Mediterranean area. For the younger warm phases it is difficult to establish a supra-regional climate pattern, and some of them may, thus, reflect regional climate variability. This highlights the complexity of regional and supra-regional scale Holocene climate patterns.

title: NOAA/WDS Paleoclimatology - Titan Cave, Wyoming Holocene Stalagmite Records over the past 5900 Years

description: The El Niño Southern Oscillation and Pacific Decadal Oscillation (PDO) are key drivers of cool-season precipitation variability in the western United States (US), including the Rocky Mountains. Together, they help modulate the north-south “precipitation dipole,” a regional climate pattern operating on multi-decadal timescales leading to dry conditions north of 40°N latitude when the south is wet, and vice versa. We investigate the natural evolution of this climate pattern using two precisely-dated (5900 years ago to present), multi-proxy, coeval stalagmite records of hydroclimate from Titan Cave, Wyoming, located just north of the modern-day dipole transition zone. Consistent trace element and stable isotope records from the two stalagmites reflect the amount and seasonality of regional precipitation, documenting decreased winter snowfall and dry conditions over multi-decadal intervals characterized by the warm phase of the PDO and more frequent and stronger El Niño events.

title: NOAA/WDS Paleoclimatology - Esper - Mount Smolikas EHS15 - PIHE - ITRDB GRC043

description: We present the longest high-elevation tree-ring width dataset in the Mediterranean reaching back to the 6th century CE. The network includes 101 living and 92 relict Pinus heldreichii Christ trees from four differently exposed sites in the 2100-2200 m a.s.l. elevation range of Mt. Smolikas in the Pindus Mountains in Greece. Though the sites were all sampled within a distance of <1 km, inter-site correlations are surprisingly low (r1550-2014 = 0.65-0.87), indicating site exposure might affect tree-ring formation. We here explore the consequence of exposure differences on the climate signals in an eastern Mediterranean treeline ecotone. Temporally stable growth/climate relationships reveal similar seasonal patterns among the four sites, but differences in signal strength. P. heldreichii growth at Mt. Smolikas is significantly controlled by temperature in April (r1951-2014 = 0.33-0.50) and precipitation in June-July (r1951-2014 = 0.23-0.42), which emphasizes the overall importance of an early growth onset and subsequent moisture conditions. The association between stem growth and April climate is strongest in the South-facing stand, supporting the significance of higher insolation rates at this thermally privileged site. Strongest summer precipitation signals are found in the NE-facing stand, where trees seem to benefit least from an early growth onset and where reduced meltwater supply may enhance the dependency on early summer precipitation. The significance of spring temperature on tree growth in all four sites constrains the emergence of a distinct summer precipitation signal in the Mt. Smolikas high elevation ecotone. Exploration of the site-specific influences on a new millennium-long tree-ring width dataset is an important step towards an improved understanding of long-term climate variability in the Eastern Mediterranean. Site-related differences in climate sensitivity in the high-elevation tree-ring network at Mt. Smolikas indicate that both temperature and precipitation during different seasons could potentially be reconstructed if distinct site exposures (S versus NE) are considered.

title: NOAA/WDS Paleoclimatology - King - Sylvan Pass - PIEN - ITRDB WY077

description: Projected warming of global surface air temperatures will further exacerbate droughts, wildfires, and other agents of ecosystem stress. We use latewood blue intensity from high-elevation Picea engelmannii to reconstruct late-summer maximum air temperature for the Greater Yellowstone Ecoregion (GYE) spanning 770-2019 CE. Using a robust regression model (r2=0.60), the 1,250-year reconstruction reveals 2016 as the single-warmest year and the warming trend since ca. 2000 as the most intense. The Medieval Climate Anomaly contained the highest-ranking warm event (1050-1070 CE) and was characterized by substantial multi-decadal variability rather than a period of prolonged, homogeneous warming. We document regional expression of past warm and cool events, such as an anomalously warm period spanning the 15th-16th centuries, and the Maunder and Dalton minima of the Little Ice Age. Summer temperature variability across the GYE shows multi-centennial agreement with trends in solar irradiance, volcanic activity, snowpack, and other regional-to-hemispheric temperature records.

title: NOAA/WDS Paleoclimatology - North fire data from Mckinney Creek Riparian/upland - IMPD USMK_001

description: Fire is an important ecological process in many western U.S. coniferous forests, yet high fuel loads, rural home construction and other factors have encouraged the suppression of most wildfires. Using mechanical thinning and prescribed burning, land managers often try to reduce fuels in strategic areas with the highest fuel loads. Riparian forests, however, are often designated as areas where only limited management action can take place within a fixed-width zone. These highly productive forests have developed heavy fuel loads capable of supporting stand-replacing crown fires that can alter wildlife habitat and ecosystem function, and contribute to stream channel erosion. Objectives of this study were to determine whether adjacent coniferous riparian and upland forests burned historically with different frequencies and seasonalities, and whether these relationships varied by forest, site, and stream characteristics. We measured dendrochronological fire records in adjacent riparian and upland areas across a variety of forest, site and stream conditions at 36 sites in three sampling areas in the northern Sierra Nevada.  Riparian fire return intervals (FRI) ranged from 8.4 to 42.3 years under a liberal filter (mean 16.6), and 10.0 to 86.5 years under a conservative filter (mean 30.0). Upland FRI ranged from 6.1 to 58.0 years under a liberal filter (mean 16.9), and 10.0 to 56.3 years under a conservative filter (mean 27.8). Riparian and upland fire return intervals were significantly different in only one quarter of the sites we sampled. Riparian and upland areas did not burn with different seasonalities, and fire events occurred primarily during the late summer-early fall dormant season in both riparian and upland areas (88% and 79% of scars, respectively). FRI was shorter in forests with a higher proportion (>22.7-37.6%) of fire-tolerant pine(Pinus spp.), sites east of the Sierra crest, lower elevation sites (<1944 m), and riparian zones bordering narrower, more incised streams (width/depth ratio <6.2). Upland areas exhibited a greater degree of fire-climate synchrony than riparian areas. Our study suggests that Sierra Nevada coniferous riparian forests bordering many montane streams might be managed for fuel loads and fire return intervals similar to adjacent upland forests.
