Magma volume, volatile emissions, and stratospheric aerosols from the 1815 eruption of Tambora [PDF]

, 2004
We suggest that the Tambora 1815 eruption was smaller than previously thought, yielding 30–33 km3 of magma. Valuable insight into the eruption is gained by comparing it to the much smaller 1991 Pinatubo event, which had a similar eruption style and rate.

Redefining the Skin Barrier: A Microbiome‐Integrated Multilayered Defense Model

Barrier Immunity, EarlyView.
ABSTRACT The skin constitutes a dynamic interface orchestrating a sophisticated multilayered defense system comprising physical, chemical, immune, and microbial barriers. This review synthesizes current understanding of the structural and functional integration of these barriers, emphasizing their synergistic interactions in maintaining cutaneous ...

A model for large-scale volcanic plumes on Io: Implications for eruption rates and interactions between magmas and near-surface volatiles. [PDF]

, 2002
Volcanic plumes deposit magmatic pyroclasts and SO2 frost on the surface of Io. We model the plume activity detected by Galileo at the Pillan and Pele sites from 1996 to 1997 assuming that magmatic eruptions incorporate liquid SO2 from near-surface ...

Financialization of Commodity Markets Co‐Movement Behind‐the‐Scenes

Journal of Futures Markets, EarlyView.
ABSTRACT In the early 2000s, institutional investors entered the commodity futures markets en masse with passive, long only, index‐type positions in sharp contrast with those typically assumed by traditional expert participants. A heated public debate soon erupted over the perceived consequences of the phenomenon—commonly referred to as ...

Transitions between explosive and effusive phases during the cataclysmic 2010 eruption of Merapi volcano, Java, Indonesia

Bulletin of Volcanology, 2016
Transitions between explosive and effusive activity are commonly observed during dome-forming eruptions and may be linked to factors such as magma influx, ascent rate and degassing.

Morphological and Computational Analysis of Additively Manufacturable Polyimide Precursors: Implications for Rationally Designing New Polyimide Structures

Macromolecular Materials and Engineering, EarlyView.
Multiscale experiments and DFT calculations establish how polyimide precursor choice governs additively manufactured morphology. PMDA/ODA and PMDA/DDS printed via a polysalt vat photopolymerization route are compared by SEM, SAXS/WAXS, and TGA. PDMA/DDS displays reduced π‐stacking and lower thermal stability compared to PMDA/ODA.

Why Deep-Water Eruptions Are So Different From Subaerial Eruptions

Frontiers in Earth Science, 2018
Magmas erupted in deep-water environments (>500 m) are subject to physical constraints very different to those for subaerial eruptions, including hydrostatic pressure, bulk modulus, thermal conductivity, heat capacity and the density of water mass ...

Dissolved Gas and Metal Composition of Hydrothermal Plumes From a 2008 Submarine Eruption on the Northeast Lau Spreading Center

Frontiers in Marine Science, 2020
Extrusion of lava onto the seafloor transports heat and mass from the lithosphere to the hydrosphere and the biosphere. During this process, large amounts of dissolved gases can be released into the ocean as hydrothermal plumes and serve as nutrients for

Magmatic volatiles in explosive rhyolitic eruptions

Geophysical Research Letters, 1981
Obsidian clasts in rhyolitic tephra deposits preserve preemption magmatic volatile contents, providing a direct means for determining the volatile content of explosively erupted magmas. Small to moderate volume Plinian eruptions (10−3 to 10−1 km³) appear to be driven by 0.5‐1.0 wt.% volatiles, consisting dominantly of H2O with minor CO2.
