Monitoring of fumarole discharge and CO2 soil degassing in the Azores: contribution to volcanic surveillance and public health risk assessment
volcanology geochemistry soil degassing monitoring risk
2015/9/10
Fluid geochemistry monitoring in the Azores involves the regular sampling and analysis of gas discharges from
fumaroles and measurements of CO2 diffuse soil gas emissions. Main degassing areas under ...
The November 2002 degassing event at Panarea Island (Italy): five months of geochemical monitoring
Aeolian Islands Panarea submarine fumaroles gas chemistry geochemical monitoring
2015/9/10
On 3rd November 2002, at about 3 km off-shore of Panarea Island (Aeolian Islands, Southern Italy), a series of
gas vents suddenly and violently opened from the seafloor at the depth of 10-15 m, with ...
Determination of volatiles in volcanic rocks and minerals with a Directly Coupled Evolved Gas Analyzing System (DEGAS) -Part I: Interpretation of degassing profiles (DEGAS-profiles) of minerals and rocks on the basis of melting experiments
volatiles magmatic rocks basaltic glass degassing Hawaiian lava remelting blacksand
2015/9/10
Volatile components in magma strongly influence many physical properties of melts and minerals. The temperature
resolved degassing analysis of volcanic crystalline and vitreous rocks gives detailed i...
Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes
noble gases solubility degassing silicate melts
2015/9/10
Noble gas solubility in silicate melts and glasses has gained a crucial role in Earth Sciences investigations and
in the studies of non-crystalline materials on a micro to a macro-scale. Due to their...
Infrared remote sensing of Earth degassing - Ground study
mofettes thermography remote sensing swarm earthquakes CO2-gas emission
2015/9/10
Geodynamical processes e.g., volcanoes, often cause degassing at the Earth surface. The geogas emanates via
mineral springs, water mofettes, or dry mofettes. It is assumed that the emerging gas influ...
Annex 1 to:Passive Degassing at Nyiragongo (D.R. Congo) and Etna (Italy) Volcanoes
Passive Degassing Nyiragongo (D.R. Congo) Etna (Italy) Volcanoes
2015/8/18
The technique for the assessment of the metal output from volcanoes was based on direct (in- plume) collection of the plume on filter substrates. Gas and aerosols in the volcanic plume have been sampl...
Passive degassing at Nyiragongo (D.R. Congo) and Etna (Italy) volcanoes
Trace elements volcanic emissions rainwater biomonitoring
2015/8/18
Volcanoes are well known as an impressive large natural source of trace elements into the troposphere. Etna (Italy) and Nyiragongo (D.R. Congo) are two stratovolcanoes located in different geological ...
Diffuse soil CO_2 degassing from Linosa island
Soil CO_2 flux Linosa Sequential Gaussian simulation
2015/8/17
Herein, we present and discuss the result of 148 measurements of soil CO2 flux performed for the first time in Linosa island (Sicily Channel, Italy), a Plio-Pleistocene volcanic complex no longer acti...
Influence of Non-Newtonian rheology on magma degassing
Non-Newtonian rheology magma degassing Soft Condensed Matter
2011/8/4
Abstract: Many volcanoes exhibit temporal changes in their degassing process, from rapid gas puffing to lava fountaining and long-lasting quiescent passive degassing periods. This range of behaviors h...
Impact vesiculation–a new trigger for volcanic bubble growth and degassing
Impact vesiculation volcanic bubble growth and degassing
2009/10/22
We highlight a potentially important trigger for bubble growth and degassing in volcanic bombs. We have successfully triggered bubble growth in previously unvesiculated samples of silicate melt during...
A comparative study of carbon dioxide degassing in river- and marine-dominated estuaries
A comparative study of carbon dioxide degassing in river marine-dominated estuaries
2014/4/21
The partial pressure of carbon dioxide (pCO2), concentration of total dissolved inorganic carbon, and total alkalinity were measured at both high tide and low tide in the surface water of three Georgi...
On the degassing state and the chemical structure of the Earth's interior inferred from noble gas isotopes—Past and recent views
Earth's interior degassing state noble gas isotopes undegassed reservoir non-convective mantle
2017/8/10
The degassing state of the Earth's interior is one of the main issues in relation to the evolution of the Earth and has been discussed by many investigators over several decades. I outline some trials...
Evolution of CO2 in Lakes Monoun and Nyos, Cameroon, before and during controlled degassing
Lake Nyos Lake Monoun hazard mitigation CO2 evolution natural recharge
2017/8/10
Evolution of CO2 in Lakes Monoun and Nyos (Cameroon) before and during controlled degassing is described using results of regular monitoring obtained during the last 21 years. The CO2(aq) profiles soo...
