Volcanology of tuff rings at Kellyville, Onewhero and Bombay, South Auckland Volcanic Field [PDF]

, 2011
The South Auckland volcanic field hosts 82 volcanic centres over an area of approximately 300 km2 in the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The intraplate, monogenetic basaltic volcanic field was active between 1.59 and 0.51 Ma, and

The impact of the 1783–1784 AD Laki eruption on global aerosol formation processes and cloud condensation nuclei [PDF]

, 2010
The 1783–1784 AD Laki flood lava eruption commenced on 8 June 1783 and released 122 Tg of sulphur dioxide gas over the course of 8 months into the upper troposphere and lower stratosphere above Iceland. Previous studies have examined the impact of the

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Must Longtermists Wish Us All Dead? A Quadrilemma

Journal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...

Eruption Dynamics and Hydrological Implications of Basaltic Volcanic Centres at Lake Taupo [PDF]

, 2010
The Taupo Volcanic Centre (TVC) is a major rhyolite centre within the Taupo Volcanic Zone, yet a small volume of the centre is comprised of monogenetic basalt volcanoes. Four TVC basalts that lie north of Lake Taupo have been examined in this study: the

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

Journal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Observation of sulphate aerosols and SO2 from volcanic eruptions using data from the Atmospheric Chemistry Experiment (ACE) [PDF]

, 2011
Infrared spectra measured by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) on board of the SCISAT satellite were used to analyse the temporal and spatial evolution of volcanic aerosols from the Kasatochi (August 2008 ...

The Potential of Stratospheric Aerosol Injection to Reduce the Climatic Risks of Explosive Volcanic Eruptions

Geophysical Research Letters
Sulfur‐rich volcanic eruptions happen sporadically. If Stratospheric Aerosol Injection (SAI) were to be deployed, it is likely that explosive volcanic eruptions would happen during such a deployment.

Influence of hydrothermal recharge on the evolution of eruption styles and hazards during the 2018–2019 activity at Kuchinoerabujima Volcano, Japan

Earth, Planets and Space, 2022
The activity of the 2018–2019 eruption of Kuchinoerabujima Volcano in Japan changed from continuous ejection of ash-laden plumes between October 21 and the middle of December, to intermittent explosive activity accompanied by several pyroclastic density ...
