Algal Bloom in a Lake near Parry Sound, Ontario

Caption

This is an algal bloom in a lake near Parry Sound, Ontario, located on the Canadian Shield, another region of Canada experiencing lakewater calcium decline. Researchers at Queen's University, Ontario, have found that unprecedented algae growth in some lakes could be linked to the decline of water calcium levels and the subsequent loss of an important algae-grazing organism that helps keep blooms at bay.
