Climate change is taking place due to significant emissions of greenhouse gases into the
atmosphere. CO 2 storage in geological formations is a promising approach that can help to …

Environmental context Tellurium, a chemical element increasingly being used in new
technologies, is an emerging contaminant. Our understanding of tellurium's environmental …

Deposition of volcanic ash into aqueous environments leads to dissolution of adsorbed
metal salts and aerosols, increasing the bioavailability of key nutrients. Volcanogenic …

The geochemistry of trace elements in surface geothermal fluids in Iceland was studied. The
sampled fluids included hot springs, mud pots, steam vents and soil solutions with …

The reactions occurring between gases/aerosols and silicate ash particles in volcanic
eruption plumes remain poorly understood, despite the fact that they are at the origin of a …

A dark region tens of kilometres wide is located in the western ablation zone of the
Greenland ice sheet. The dark appearance is caused by higher amounts of dust relative to …

Abstract High-temperature (1084° C) fumarolic emissions from a spatter cone at the Erta Ale
north pit crater granted a rare opportunity to collect Giggenbach bottles, condensates, and …

Long-lived basaltic volcanic eruptions are a globally important source of environmentally
reactive, volatile metal pollutant elements such as selenium, cadmium and lead. The 2018 …

This study reports on the first quantitative assessment of the geochemical cycling of
volcanogenic elements, from their atmospheric release to their deposition back to the …

The 2014 Bárðarbunga rifting event in Iceland resulted in a 6‐month long eruption at
Holuhraun. This eruption was characterized by high lava discharge rate and significant gas …
