‘Subtle changes in calcification can cause dramatic changes in skeletal performance …’
LINZ — Scientists working at an underwater volcano near Sicily say they have new evidence that ocean acidification could change fundamental parts of marine ecosystems.
Their research shows that acidification weakens algal skeletons. Even a small loss of skeletal calcification caused by exposure to corrosive waters can have a significant impact and leave algae at risk of losing access to light and nutrients, the researchers concluded in a new paper published in the Royal Society’s Biology Letters.

2011 event was three times larger than any previously recorded bloom
By Summit Voice
SUMMIT COUNTY — A record-breaking 2011 algae bloom — three time larger than any on record — in Lake Erie is a warning sign, as global warming is expected to generate more intense rainstorms that flush fertilizers from surrounding fields into the water.
The Lake Erie bloom was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake circulation and warm temperatures, the researchers said, concluding that the lake will continue to experience extreme blooms unless agricultural practices change.
