Acidic water hits Canadian scallops

Acidic water hits Canadian scallops

Ten million scallops that have died in the waters near Qualicum Beach due to rising ocean acidity are the latest victims in a series of marine die-offs that have plagued the West Coast for a decade.

Human-caused carbon dioxide emissions in the atmosphere are being absorbed by the ocean and may have pushed local waters through a “tipping point” of acidity beyond which shellfish cannot survive, according to Chris Harley, a marine ecologist at the University of B.C.

Rising ocean acidity is a global phenomenon, made worse by higher natural acidity in local waters, Harley said.
