description: We developed the first tree-ring chronology of Chukrasia tabularis from a moist tropical forest in Bangladesh, spanning the 102-year period 1911–2012. The species showed wood anatomically clear annual tree-ring boundaries which crossdated between tree individuals. Bootstrapped correlation analyses revealed that the ring-width index was significantly negatively correlated with current year mean and minimum temperatures. This relationship was stronger during the dry season (November–March), the pre-monsoon (February–April) and the post-monsoon season (September–November) than during the main monsoon season (May–August). We interpret this result as an indication that temperature-driven higher evapotranspiration outside the main rainy season leads to water stress limiting tree growth. This is confirmed by negative correlations of the ring-width index with the Palmer Drought Severity Index (PDSI) during the dry season. Precipitation did not show significant relationships to tree growth, except in current year June. However, cloud cover strongly negatively affected tree growth, likely by reducing photosynthetic capacity particularly during the rainy summer (May–August) monsoon season. On a regional scale, the ring-width index was correlated with both Indian Ocean and Pacific Ocean sea surface temperature (SST) anomalies, but during different seasons. Ring width of C. tabularis was also significantly correlated with the El Niño Southern Oscillation (ENSO). Monthly Niño 3.4 region positive temperature anomalies enhanced current year tree growth but negative temperature anomalies reduced tree growth in the following year mainly through modulating local climate. Hence, tree-ring variations of C. tabularis in Bangladesh record local and regional climate signals and are a potential proxy to reconstruct local and regional paleoclimatic variability during the past centuries.

title: NOAA/WDS Paleoclimatology - Schneider - Berlin Alpenrose den14 - QURO - ITRDB DEU314

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 - Northeast African Precipitation and Vegetation Biomarker Data over the last 4.5 million years

description: The eastern Mediterranean sapropels, paced by insolation, provide a unique archive of African monsoon strength over the Late Neogene. However, the longer-term climate of this region lacks characterization within the context of changes in ice volume, sea surface temperature gradients, and terrestrial ecosystems. Here, we examine C28 n-alkanoic acid leaf wax hydrogen and carbon isotopes in sapropels, sourced from northeast Africa, along with vegetation-corrected precipitation isotopes, derived from astronomically dated sediment cores from ODP 160 Sites 966 and 967 since 4.5 million years ago. Despite sampling only wet-phase sapropels for African monsoon variability, we find a larger range in hydrogen isotopes than previously published data across wet-dry precession cycles, indicating the importance of long-term modulation of Green Sahara phases throughout the Neogene. An influence of orbital properties on regional monsoonal hydroclimate is observed, controlling up to 50% of total hydrogen isotope variance, but large changes outside of these typical frequencies account for at least 50% of the total variance. This secular trend may track changes in ice volume, tropical sea surface temperature, sea surface temperature gradients, or even lower-frequency orbital cycles. Long-term hydroclimate and environmental shifts provide new contexts for milestone events in northeast African hominin dispersal and evolution.

title: NOAA/WDS Paleoclimatology - Clumped isotope measurements and temperature estimates from Palouse Loess, Washington from 34000 to 9000 BP

description: Since the last glacial period, North America has experienced dramatic changes in regional climate, including the collapse of ice sheets and changes in precipitation. We use clumped isotope (∆47) thermometry and carbonate d18O measurements of glacial and deglacial pedogenic carbonates from the Palouse Loess to provide constraints on hydroclimate changes in the Pacific Northwest. We also employ analysis of climate model simulations to provide further constraints on the hydroclimate changes in the Pacific Northwest. The coldest clumped isotope soil temperatures T(∆47) (13.5 ±1.9 °C to 17.1 ±1.7 °C) occurred ~34,000-23,000 years ago. Using a soil-to-air temperature transfer function, we estimate Last Glacial Maximum (LGM) mean annual air temperatures of ~-5.5 °C and warmest average monthly temperatures (i.e., mean summer air temperatures) of ~4.4 °C. These data indicate a regional warming of 16.4 ± 2.6 °C from the LGM relative to modern temperatures of 10.9 °C, which was about three times the global average. Proxy data provides locality constraints on the boundary of the cooler anticyclone induced by LGM ice sheets, and the warmer cyclone in the Eastern Pacific Ocean. Climate model analysis suggests regional amplification is due to the proximal location of the study area to the Laurentide Ice Sheet margin and the impact of the glacial anticyclone on the region, as well as local albedo. Isotope-enabled model experiments indicate variations in water d18O largely reflect atmospheric circulation changes and enhanced rainout upstream that brings more depleted vapor to the region during the LGM.

title: NOAA/WDS Paleoclimatology - Bonney - Wilcox CA (Site 15) - ACSH - ITRDB CANA670

description: Time-series of satellite-derived vegetation proxies and tree-rings widths (TRW) are similar, providing temporal records of forest productivity change from different perspectives and processes. Previous research on this relationship has focused on temperature or moisture limited coniferous forests, using lower spatial resolution (e.g., 8000 m) satellites and normalized difference vegetation index (NDVI) to test relationships over 15-30 years. There is an opportunity to leverage recent advances in building Landsat (30 m) time-series to expand comparisons into new forest types (e.g., coniferous vs. deciduous), areas (e.g., fragmented forests) and over longer periods (e.g., nearly 50 years). However, a better understanding of factors that influence relationship strength is required. We compared tree-ring measurements, converted to a ring width index (RWI), and Landsat tasseled cap angle (TCA) derived canopy cover (CC) from 1972 to 2018 across 16 deciduous, mixed, and coniferous stands in southern Ontario, Canada. For all chronologies, overall relationship strength was assessed with correlation approaches (RWI-CC, both vs. climate), and shorter-term increase-decline trends were compared with segmented regression. There were significant forest type differences, with coniferous chronologies correlating stronger with CC than deciduous. Deciduous chronologies and CC had opposite connections with summer temperature, with climate warming increasing CC and coniferous RWI but not deciduous RWI from 1980 to 2010. More recent decline at most sites appears related to a major ice storm, but multiple factors may be coexisting. We tested the utility of tree-rings for validating nearly 50 years of Landsat-observed change in urban-rural temperate forests, identifying useful connections at coniferous sites. However, there are limitations to comparing long-term Landsat time-series (based on yearly summer data) with annual tree-ring growth.

title: NOAA/WDS Paleoclimatology - Marine Oxygen Distributions in the Pre-Industrial and Pliocene

description: Oxygen minimum zones (OMZs) play a critical role in global biogeochemical cycling and act as barriers to dispersal for marine organisms. OMZs are currently expanding and intensifying with climate change, however the past distributions of OMZs are relatively unknown. Here we present evidence for widespread pelagic OMZs during the Pliocene (5.3-2.6 Mya), the most recent Epoch with atmospheric CO2 analogous to modern (~ 400-450 ppm). The global distribution of OMZ-affiliated planktic foraminifer, Globorotaloides hexagonus, and Earth System and Species Distribution Models show that the Indian Ocean, Eastern Equatorial Pacific, eastern South Pacific, and eastern North Atlantic all supported OMZs in the Pliocene, as today. By contrast, low-oxygen waters were reduced in the North Pacific and expanded in the North Atlantic in the Pliocene. This spatially explicit perspective reveals that a warmer world can support both regionally expanded and contracted OMZs, with intermediate water circulation as a key driver.
