USING MEDIUM-RESOLUTION SATELLITE IMAGES TO ASSESS IMPACT OF VOLCANIC EXPLOSIONS ON ECOSYSTEMS [PDF]

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2020
Activation of volcanic processes can lead to catastrophic consequences for ecosystems, loss of life and significant material damage. Territory of the Kuril Islands and the Kamchatka territory is a risk zone.

ANALYSIS OF CHANGES IN THE STATE OF ECOSYSTEMS ON ATLASOVA ISLAND (KURIL ISLANDS) [PDF]

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2020
The territory of the Kuril Islands is a chain of volcanic structures and is subject, to certain extent, to volcanic hazards. Atlasova Island is composed of products of the Alaid volcano, which is characterized by effusive and explosive activity.

Calcareous Skarn-like Mineral Paragenesis from Unaltered Basalt of the Alaid Volcano (Kuril–Kamchatka Island Arc)

Minerals
Conditions of high-temperature volcano-related mineral formation are a source of the new and rare minerals and their associations; they are rather fragmentarily described for volcanic systems as a whole, except for several objects characterized in this ...

Changes in Abiotic Drivers of Green Sea Urchin Demographics following the Loss of a Keystone Predator

Journal of Marine Sciences, Volume 2023, Issue 1, 2023., 2023
Sea urchin population demographics can respond to changes in keystone species abundances, with the magnitude of these responses varying depending on environmental influences. In this study, sea urchin populations were surveyed across 15 Aleutian archipelago islands over a 30‐year period to understand how patterns of sea urchin demography (density ...

Correlations Between Subduction of Linear Oceanic Features and Arc Volcanism Volume Around the Pacific Basin

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 12, December 2022., 2022
Abstract Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions. In this study, we address a fundamental question, namely, how do subduction zones and volcanic arcs respond to the subduction of “atypical” oceanic lithosphere.

The role of airborne volcanic ash for the surface ocean biogeochemical iron-cycle: a review [PDF]

, 2010
Iron is a key micronutrient for phytoplankton growth in the surface ocean. Yet the significance of volcanism for the marine biogeochemical iron-cycle is poorly constrained.
