Sentences with phrase «degassing by»

For Pavlof in particular, the scientists say in their paper, this distinction could help monitor the hazards produced during explosive degassing by the volcano.

QUOTE: «As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in up - wellings; carbon absorbed by plants months to centuries ago is degassed by soils Sorry, there is a fundamental lack of knowledge of dynamic systems here: as long as the total of the CO2 influxes is the same as the total of the CO2 outfluxes, nothing happens in the atmosphere.

As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in upwellings; carbon absorbed by plants months to centuries ago is degassed by soils.

A new mission would likely head for Encke, a comet described as «evolved, degassed, used - up, and as old as possible» by Contour mission leader Joseph Veverka, a planetary scientist at Cornell University.

By modeling the process of magma degassing, the researchers could reproduce the chemistry of the fluids that form metal deposits.

Degassing of ash erupted during 1976 by Augustine Volcano in Alaska released 525 x 106 kg of chlorine (± 40 %), of which 82 x 106 to 175 x 106 kg may have been ejected into the stratosphere as hydrogen chloride [HCl].

There's typically an initial ocean uptake as tropical East Pacific upwelling (CO2 degassing) is reduced, followed by a stronger release of carbon from land.

The human fossil fuel CO2 emissions spike is more like an asteroid impact than the slow degassing of CO2 from metamorphic decarbonization of carbonate rocks at subduction zones by the slow grinding away of plate tectonics.

Thus an increase of CO2 in the atmosphere, whatever the cause, will decrease the degassing of the warm parts of the oceans and increase the absorption by the cold parts of the oceans, even if warmer oceans were the initial cause of the increase.

Nothing would happen with the total quantity of CO2 (whatever type) if still Rin = Rout, but that is not the case: the increase of total CO2 in the atmosphere increases the uptake by oceans and vegetation and decreases the oceanic degassing.

What's missing from these studies themselves is evidence that the Siberian shelf degassing is new, a climate feedback, rather than simply nature - as - usual, driven by the retreat of submerged permafrost left over from the last ice age.

The importance of such thaw - discontinuities can not be underplayed in a model of catastrophic devolatilisation (Shakhova, 2014), as illustrated by Mars where violent degassing equivalent to 20 Yamal explosions per km ² occurs through sub-mound palaeo - taliks alone (e.g., Figure above).
