Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Patterns of Fine Ash Dispersal Related to Volcanic Activity at West Mata Volcano, NE Lau Basin

Frontiers in Marine Science, 2019
Extensive deep (>1500 m) non-hydrothermal ash-rich plumes were present in the water column surrounding West Mata submarine volcano (NE Lau basin) during eruptive phases, but were absent when West Mata was quiescent.

HUNGA-TONGA-HUNGA-HA’PAI VOLCANIC ERUPTION/EXPLOSION AND TSUNAMIS OF 14-15 JANUARY 2022 – Overview and Analysis [PDF]

Science of Tsunami Hazards, 2022
The explosive eruption/collapse of the submarine portion of the volcano Hunga-Tonga- Hunga-Ha'apai (HT-HH) on the Tonga Kermadec volcanic arc in the southwest Pacific on 15 January 2022 occurred at the end of many weeks of activity. It was a truly global

On the Ionospheric Disturbances in New Zealand and Australia Following the Eruption of the Hunga Tonga‐Hunga Ha'apai Volcano on 15 January 2022

Space Weather, 2023
The Hunga Tonga‐Hunga Ha'apai (hereafter HTHH) submarine volcano erupted at 04:14:45 UT on 15 January 2022, causing ionospheric disturbances. This paper uses carrier phase observations from GNSS tracking stations in New Zealand and Australia to calculate

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

Environmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.

Hydroacoustic Monitoring of Mayotte Submarine Volcano during Its Eruptive Phase

Geosciences
Submarine volcanoes are more challenging to monitor than subaerial volcanoes. Yet, the large eruption of the Hunga Tonga-Hunga Ha’apai volcano in the Tonga archipelago in 2022 was a reminder of their hazardous nature and hence demonstrated the need to ...

Observation and Modeling of Hydrothermal Response to the 2015 Eruption at Axial Seamount, Northeast Pacific

Geochemistry, Geophysics, Geosystems, 2018
The 2015 eruption at Axial Seamount, an active volcano at a depth of 1500 m in the Northeast Pacific, marked the first time a seafloor eruption was detected and monitored by an in situ cabled observatory—the Cabled Array, which is part of the Ocean ...

Observing Electrical Discharge With High 3D Spatial Resolution

High Voltage, EarlyView.
ABSTRACT This study introduces an application of binocular stereo vision technology to achieve high‐resolution 3D visualisation of submillimeter discharge channels. The proposed method can capture the depth information of weak luminous discharges and provide 3D discharge trajectories, providing new insights into the discharge mechanism.

And then there was us Et puis nous sommes apparus

Journal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

The Big Picture: Religion and Global Comparative History

Journal of Religious History, EarlyView.
This article considers what a ‘big picture’ approach to global religious history might look like, and in particular the implications of deploying the comparative method across much larger stretches of time and space than historians normally attend to. It will begin by reflecting on the epistemological moods that have hindered this project to date, the ...
