FRISCO — Studying volcanic vents near the Italian coast has helped scientists gain a glimpse of how increasingly acidic waters could impoverish ecosystems by reducing biodiversity. The study focused in differing levels of acidity around the vents, where carbon dioxide gas bubbles into the water naturally.
FRISCO —In what must have been incredible displays of fire and ice, ancient volcanoes once erupted under massive glacial ice sheets, leaving deposits that could help paleoclimatologists unravel some ice age puzzles.
In a recent study, University of British Columbia researchers surveyed those deposits at the Kima’ Kho tuya, which erupted under an ice sheet about 1.8 million years ago. Their findings suggest that he ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated.
