title: NOAA/WDS Paleoclimatology - Belukha Glacier, Siberian Altai 300 Year Ice Core Heavy Metals Data

description: The development of strategies and policies aiming at the reduction of environmental exposure to air pollution requires the assessment of historical emissions. Although anthropogenic emissions from the extended territory of the Soviet Union (SU) considerably influenced concentrations of heavy metals in the Northern Hemisphere, Pb is the only metal with long-term historical emission estimates for this region available, whereas for selected other metals only single values exist. Here we present the first study assessing long-term Cd, Cu, Sb, and Zn emissions in the SU during the period 1935-1991 based on ice-core concentration records from Belukha glacier in the Siberian Altai and emission data from 12 regions in the SU for the year 1980. We show that Zn primarily emitted from the Zn production in Ust-Kamenogorsk (East Kazakhstan) dominated the SU heavy metal emission. Cd, Sb, Zn (Cu) emissions increased between 1935 and the 1970s (1980s) due to expanded non-ferrous metal production. Emissions of the four metals in the beginning of the 1990s were as low as in the 1950s, which we attribute to the economic downturn in industry, changes in technology for an increasing metal recovery from ores, the replacement of coal and oil by gas, and air pollution control.

title: NOAA/WDS Paleoclimatology - Carpathian Mountains, 1163-2005 AD, annual ring widths, Pinus cembra L., PAGES Euro-Med 2k Version

description: The first 1,000 year long Carpathian tree-ring width chronology was established based on living and subfossil stone pine (Pinus cembra L.) samples from an
       upper timberline forest located in Calimani Mts. (Romania). Tree-ring data were standardized using the regional curve standardization method in order to preserve the low
       and medium frequency climate signals. The de-trended index strongly correlates with summer mean temperature both at annual and decadal scales. The Calimani summer
       mean temperature anomalies were reconstructed for the period AD 1163-2005 applying the rescaling method. This new climate proxy from the Carpathians shows similar
       fluctuations to other North Hemispheric temperature reconstructions, but with periods of distinct differences. The fingerprint of Little Ice Age in the Calimani area is
       visible between AD 1370 and 1630 followed by lagged cold decades in AD 1820 and 1840. The recent warming is evident only after the 1980s in our reconstruction.
description:   Living trees were sampled according to dendrochronological principles and conventions (Fritts 1976; Cook and Kairiukstis 1990; Popa 2004) from altitudes ranging from
       1,450 to 1,850 m a.s.l. There were limited variations in the ecology and environment of the sampling area, ensuring the homogeneity of growth data.
       LINTAB equipment and TSAP 0.53 software (Rinntech 2005) were used for measuring the annual ring widths with a precision of 0.01 mm, as well as for cross-dating the
       growth series by graphical comparison. The results were checked for missing ring and dating error using the COFECHA software (Holmes 1983; Grissino-Mayer 1997). Samples missing pith or showing low correlation
       (<0.25) with the master chronology were excluded from the analysis. The final dataset comprised 410 individual series from 207 trees (65 series from living trees and 355 series from dead trees).

title: NOAA/WDS Paleoclimatology - Atlantic Ocean 23,000 Year Benthic Foraminifera Stable Isotope Data

description: Approximately synchronous with the onset of Heinrich Stadial 1 (HS1), d13C decreased throughout most of the upper (~1000-2500 m) Atlantic, and at some deeper North Atlantic sites. This early deglacial d13C decrease has been alternatively attributed to a reduced fraction of high-d13C North Atlantic Deep Water (NADW) or to a decrease in the NADW d13C source value. Here we present new benthic d18O and d13C records from three relatively shallow (~1450-1650 m) subpolar Northeast Atlantic cores. With published data from other cores, these data form a depth transect (~1200-3900 m) in the subpolar Northeast Atlantic. We compare Last Glacial Maximum (LGM) and HS1 data from this transect with data from a depth transect of cores from the Brazil Margin. The largest LGM-to-HS1 decreases in both benthic d13C and d18O occurred in upper waters containing the highest NADW fraction during the LGM. We show that the d13C decrease can be explained entirely by a lower NADW d13C source value, entirely by a decrease in the proportion of NADW relative to Southern Ocean Water, or by a combination of these mechanisms. However, building on insights from model simulations, we hypothesize that reduced ventilation due to a weakened but still active Atlantic Meridional Overturning Circulation also contributed to the low d13C values in the upper North Atlantic. We suggest that the benthic d18O gradients above ~2300 m at both core transects indicate the depth to which heat and North Atlantic deglacial freshwater had mixed into the subsurface ocean by early HS1.

title: NOAA/WDS Paleoclimatology - Sullivan - Agashashok Forest - PCGL - ITRDB AK149

description: The position of the Arctic treeline, which is a key regulator of surface energy exchange and carbon cycling, is widely thought to be controlled by temperature. Here, we present evidence that soil nutrient availability, rather than temperature, may be the proximate control on growth of treeline trees at our study site in northwest Alaska. We examined constraints on growth and allocation of white spruce in three contrasting habitats. The habitats had similar aboveground climates, but soil temperature declined from the riverside terrace to the forest to the treeline. We identified six lines of evidence that conflict with the hypothesis of direct temperature control and/or point to the importance of soil nutrient availability. First, the magnitude of aboveground growth declined from the terrace to the forest to the treeline, along gradients of diminishing soil nitrogen (N) availability and needle N concentration. Second, peak rates of branch extension, main stem radial and fine root growth were generally not coincident with seasonal air and soil temperature maxima. At the treeline, in particular, rates of aboveground and fine root growth declined well before air and soil temperatures reached their seasonal peaks. Third, in contrast with the hypothesis of temperature-limited growth, growing season average net photosynthesis was positively related to the sum of normalized branch extension, main stem radial and fine root growth across trees and sites. Fourth, needle nonstructural carbohydrate concentration was significantly higher on the terrace, where growth was greatest. Fifth, annual branch extension growth was positively related to snow depth, consistent with the hypothesis that deeper snow promotes microbial activity and greater soil nutrient availability. Finally, the tree ring record revealed a large growth increase during late 20th century climate warming on the terrace, where soil N availability is relatively high. Meanwhile, trees in the forest and at the treeline showed progressively smaller growth increases. Our results suggest temperature effects on tree growth at our study sites may be mediated by soil nutrient availability, making responses to climate change more complex and our ability to interpret the tree ring record more challenging than previously thought.

title: NOAA/WDS Paleoclimatology - La Alberca Lake, Guanajuato, Mexico 6,700 Year Geochemical Data

description: The relationship between climatic-environmental changes and its cultural implications in the Northern Mesoamerican Frontier is poorly understood, because of the lack of high-resolution well-dated records. In this work we present a high-resolution paleoclimate and paleoenvironmental reconstruction of the Northern Mesoamerican Frontier for the last 6700 yr BP, using laminated sediments from La Alberca maar lake, Guanajuato. For this purpose, we used different techniques such as X-ray fluorescence, microfacies analysis, magnetic parameters, bulk sedimentary d18O, d13C records and twelve AMS 14C ages. In Prehistory times, different climatic events are well defined. At around 5600 yr BP, our data indicate the end of Holocene Thermal Maximum and a subsequent decline of monsoon strength is observed. Variable hydrological conditions start to dominate around ~4400 yr BP consistent with the rise of latitudinal variations of the Intertropical Convergence Zone. A rise in sedimentation rate and increase in Amaranthaceae pollen percent occurred between ~225 CE- 600 CE are linked to the beginning of agricultural activities by the Chupicuaro Pre-Hispanic culture. In Historical times, during the Epiclassic period, we interpreted two drought events around ~700-790 CE and ~810-880, supporting the Armillas' theory that drastic climate events motivated the social changes and shift in the geographic position of Northern Mesoamerican Frontier. In the final part of the Postclassic period a pluvial interval is associated with the rise of Tarascan culture in the area. We propose that droughts and pluvial periods between 600 and 1500 CE are connected with SSTs variability of the Atlantic Basin.

title: Shift in the Microbial Community Composition in Lake Wetland Sediments in the Source Region of the Yellow River Linked to Environmental Factors

description: The source region of the Yellow River, as the main flow-producing area, contributes more than 35% of the total flow of the Yellow River. Here, we surveyed the spatial distribution of the bacterial and fungal communities in the 17 sedimental sites of Longyangxia Valley and Donggi Conag Lake within the source region of the Yellow River. The results revealed that bacterial richness and diversity were higher at the lower elevation of Longyangxia Valley (2588 m) than at higher elevation of Donggi Conag Lake (4096 m), while no obvious differences in fungal richness and diversity were observed. The abundance of the bacterial phylum Actinobacteriota increased in Donggi Conag Lake (30.8%) compared to Longyangxia Valley (15.9%) as the elevation increased. Meanwhile, the abundance of the fungal phylum Rozellomycota decreased (17.6–3.0%) as the elevation increased. The redundancy analysis suggested that the structures of the bacterial and fungal communities were influenced by environmental factors including elevation, organic matter content, hydrolyzed nitrogen, total phosphorus, total potassium, and pH. The results highlighted that rather than the fungal community, the bacterial community in sediments exhibited more significant spatial variation in lake wetlands driving by the influence of elevation and physicochemical variables.
