title: NOAA/WDS Paleoclimatology - Isla Los Testigos, Venezuela Coral Sr/Ca Data and SST from 1870-1995 CE

description: Sea surface temperature (SST) in the Tropical North Atlantic (TNA) ocean is a key component of the Atlantic Multidecadal Oscillation (AMO) and plays an important role in orchestrating hydroclimatic anomalies on adjacent continents. However, the narrow timespan of reliable instrumental SST records and the limited availability of paleoclimate SST records in the TNA region hinder our understanding of long-term TNA climate variability. Coral Sr/Ca has been extensively used as an SST proxy, allowing us to extend SST records into the pre-instrumental era. Here, we present replicated Sr/Ca records at bimonthly resolution from two Siderastrea siderea corals that grew offshore Isla Testigo Grande (Venezuela), spanning from 1871 to 1994 C.E. to evaluate SST variability in the TNA region. The reconstructed SST reflects TNA variability linked to regional hydroclimate extremes on nearby continents, including precipitation in Northeast Brazil and the Sahel, as well as decadal changes in hurricane activity. The multidecadal variability of reconstructed SST is coherent with instrumental records and paleoclimate reconstructions of the AMO, demonstrating its ability to represent the tropical component of the AMO. This suggests that the coral-based SST can serve as a valuable tool for investigating the consistency of the TNA and AMO relationship, potentially resolving disagreement among paleoclimate reconstructions in the pre-instrumental era. Overall, this study extends the Atlantic coral record further into the past and provides insights into the long-term interplay between TNA SST variability, the AMO, and tropical Atlantic climate.

title: Coronary Drug Project

description: To determine whether regular administration of lipid modifying drugs (clofibrate, nicotinic acid, estrogen, dextrothyroxine) to men with a documented myocardial infarction would result in significant reduction in total mortality over a five year period. Secondarily, to determine whether the degree to which these drugs changed serum lipids was correlated with any effect on mortality and morbidity rates; to gain further information on the long-term prognosis of myocardial infarction (by studying the control group as intensively as the treatment group); to acquire further experience and knowledge concerning the techniques and methodology of long-term clinical trials; to determine, in a substudy, the effectiveness of aspirin, a platelet inhibitor, in reducing recurrences of myocardial infarction.

title: NOAA/WDS Paleoclimatology - Yucatán Peninsula Stable Isotope Data from 43 to 26.6 ka BP

description: We reconstructed hydroclimate variability in the Yucatán Peninsula (YP) based on stalagmite oxygen and carbon isotope records from a well-studied cave system located in the northeastern YP, a region strongly influenced by Caribbean climate dynamics. The new stalagmite isotopic records span the time interval between 43 and 26.6 ka BP, extending a previously published record from the same cave system covering the interval between 26.5 and 23.2 ka BP. Stalagmite stable isotope records show dominant decadal and multidecadal variability, and weaker variability on millennial timescales. These records suggest significant precipitation declines in the broader Caribbean region during Heinrich events 4 and 3 of ice-rafted discharge into the North Atlantic, in agreement with the antiphase pattern of precipitation variability across the equator suggested by previous studies. On millennial timescales, the stalagmite isotope records do not show the distinctive saw-tooth pattern of climate variability observed in Greenland during Dansgaard–Oeschger (DO) events, but a pattern similar to North Atlantic sea surface temperature (SST) variability. We propose that shifts in the mean position of the Intertropical Convergence Zone (ITCZ), per se, are not the dominant driver of last glacial hydroclimate variability in the YP on millennial timescales but instead that North Atlantic SSTs played a dominant role. Our results support a negative climate feedback mechanism whereby large low latitude precipitation deficits resulting from AMOC slowdown would lead to elevated salinity in the Caribbean and ultimately help reactivate AMOC and Caribbean precipitation. However, because of the unique drivers of future climate in the region, predicted twenty-first century YP precipitation reductions are unlikely to be modulated by this negative feedback mechanism.

title: NOAA/WDS Paleoclimatology - Märker - Popradske Pleso Forest - PCAB - ITRDB SVK026

description: Understanding tree growth and forest dynamics under climate change is paramount to predict changes in carbon cycling, forest development, and ecosystem services. At temperature limited sites, such as alpine treelines, tree growth is often assumed to benefit from rising temperatures, while increased drought may offset potential benefits. Tree size is known to be related to climate sensitivity and drought induced mortality, with large trees generally suffering the most from drought. To assess the relationship of tree size and climate sensitivity for Norway spruce trees at treeline, we collected 158 tree cores at treeline and the adjacent closed canopy forest in the High Tatra Mountains in Slovakia. Size classes were established based on size class isolation of the total sample set, yielding artificial tree ring chronologies with a constant size over time. We ran moving-window correlation analyses to assess the temporal development of climate sensitivity. We found climate-growth correlations to be non-stationary and with similar trends among size classes. In general, trees are temperature limited during the growing season, but correlations have shifted from June to July in recent decades. Additionally, the largest trees show an increased and significant sensitivity to August and September drought conditions in the year preceding growth. These findings emphasize the increasing influence of drought constraints on tree growth, even at supposedly temperature limited treeline sites.

title: Electron doping of exfoliated multilayer graphene induced by dissociative H<sub>2</sub> adsorption due to long-term exposure to 80-bar H<sub>2</sub> gas

description: Semiconducting graphene is expected to replace silicon in the electronics industry, and various methods have been proposed for this purpose. In this study, we demonstrate that the long-term exposure of multilayer graphene to 80 bar of molecular hydrogen induces electron doping in graphene. Ambipolarity behavior disappeared, and the current in the transfer curves decreased and increased in the negative gate voltage (<i>V</i><sub><i>g</i></sub>) and positive <i>V</i><sub><i>g</i></sub> regions, respectively. The charge neutrality point shifted from 4.18 to over −80 V. Two resonant scatterings due to hydrogen adatoms were observed in the temperature-dependent transfer curves. For multilayer graphene with a boundary (edge), different behavior was observed in the transfer characteristics. Upon exposure to 80 bar of H<sub>2</sub> pressure, the drain current of the time-dependent transfer curve rapidly decreased; however, it increased in the positive <i>V</i><sub><i>g</i></sub> region after 60 h of exposure to H<sub>2</sub>. Structural changes, particularly an increase in C‒H bonding, were observed using various characterization methods. These results were interpreted by the dissociative H<sub>2</sub> adsorption of graphene. Molecular dynamics simulations also revealed the presence of electron doping due to dissociative adsorption. Furthermore, the simulations confirmed that dissociative adsorption occurred on the surface layer and at vacancies and defects.
