Short-lived tectonic switch mechanism for long-term pulses of volcanic activity after mega-thrust earthquakes
Short-lived tectonic switch mechanism long-term pulses volcanic activity mega-thrust earthquakes
2015/1/6
Eruptive rates in volcanic arcs increase significantly after subduction mega-thrust earthquakes. Over short to intermediate time periods the link between mega-thrust earthquakes and arc response can b...
New zircon data supporting models of short-lived igneous activity at 1.89 Ga in the western Skellefte District, central Fennoscandian Shield
New zircon data supporting models short-lived igneous activity 1.89 Ga in the western Skelleftea District central Fennoscandian Shield
2014/12/31
New U-Th-Pb zircon data (SIMS) from three intrusive phases of the Palaeoproterozoic Viterliden intrusion in the western Skellefte District, central Fennoscandian Shield, dates igneous emplacement in a...
Entrainment and retention of the coastal larval fish assemblage by a short-lived, submesoscale, frontal eddy of the East Australian Current
a short-lived Entrainment
2014/4/2
We examined the fate of larval fish assemblages after the East Australian Current (EAC) had separated from
the coast and larval fish were advected eastward along the Tasman Front. There was no differ...
Evolution of the Solar Nebula. IX. Gradients in the Spatial Heterogeneity of the Short-Lived Radioisotopes $^{60}$Fe and $^{26}$Al and the Stable Oxygen Isotopes
Evolution Solar Nebula IX. Gradients Spatial Heterogeneity Short-Lived Stable Oxygen Isotopes
2011/9/27
Short-lived radioisotopes (SLRI) such as $^{60}$Fe and $^{26}$Al were likely injected into the solar nebula in a spatially and temporally heterogeneous manner. Marginally gravitationally unstable (MGU...
Sensitivity of stratospheric Bry to uncertainties in very short lived substance emissions and atmospheric transport
stratospheric Bry lived substance emissions atmospheric transport
2011/2/25
We evaluate the sensitivity of Bry entering the stratosphere with a simplified model that allows calculations over a wide parameter range for parameters that are currently poorly quantified. The model...
Emission location dependent ozone depletion potentials for very short-lived halogenated species
Emission location ozone depletion potentials short-lived halogenated species
2010/12/28
We present trajectory-based estimates of Ozone Depletion Potentials (ODPs) for very short-lived halogenated source gases as a function of surface emission location. The ODPs are determined by the frac...
Short-lived star-forming giant clumps in cosmological simulations of z~2 disks
galaxies evolution— galaxies formation— galaxies high-redshift—galaxies structure
2010/11/9
Many observed massive star-forming z ≈ 2 galaxies are large disks that exhibit irregular morphologies, with ≈ 1 kpc, ≈ 108-10M⊙ clumps. We present high-resolution cosmological SPH simulations that zoo...
Vertical transport rates and concentrations of OH and Cl radicals in the Tropical Tropopause Layer from observations of CO2 and halocarbons: implications for distributions of long- and short-lived chemical species
Vertical transport rates OH and Cl radicals the Tropical Tropopause Layer long- and short-lived chemical species
2010/8/16
Rates for large-scale vertical transport of air in the Tropical Tropopause Layer (TTL) were determined using high-resolution, in situ observations of CO2 concentrations in the tropical upper troposphe...
