Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[From Latin (Pontus) Euxīnus, the Black Sea (since the deeper waters of the Black Sea constitute such an environment), from Greek (Pontos) Euxeinos, literally, hospitable (sea), perhaps a euphemism for earlier (Pontos) Axeinos, inhospitable (sea) (a-, not + xenos, xeinos, guest, stranger; see xeno-), perhaps a folk etymology of a name of Scythian origin; akin to Avestan axšaēna-, dark-colored, blue.]

  • CO2 injected into the atmosphere by the Siberian Traps has been postulated as a major factor leading to the end-Permian mass extinction by facilitating global warming, widespread ocean stratification, and development of anoxic, euxinic and CO2-rich deep waters.
