What is ocean acidification?

[admin]

The global increase in carbon dioxide emissions is not only warming our planet at an alarming rate, but it's also making our oceans more acidic.

While there's apparent changes occurring, perhaps the serious nuclear plant meltdown at Fukushima is also a main contributing factor since it's still leaking steadily in both our atmosphere as well as our oceans since 2011.

Is nitrogen run off. The solutions are either to curtail usage or reestablish marshes, deltas and so forth that neutralize before reaching ocean. In addition, free the phosphates as this helps the break down.

Thirty years of unique data reveal what's really killing coral reefs

Coral bleaching is not just due to a warming planet, but also a planet that is simultaneously being enriched with reactive nitrogen from sources like improperly treated sewage, and fertilizers. Nitrogen loading from the Florida Keys and greater Everglades ecosystem caused by humans is the...

Florida's Corals Are Dying Off, But It's Not All Due To Climate Change, Study Says

A new study from the Florida Keys shows that a lot of the stress on corals comes from local sources, providing hope that community action can help save them.

These changes have been documented and tracked well before the Fukoshima disaster. Additionally, acidification would not be the expected result of radiation, that's a whole different set of problems.

Radiation would be stress, slows breeding of organisms that sink carbon and so forth. Ordinarily this may be a small impact but there's a deficiency of calcium, phosphorus and an excess of nitrogen at the moment.

Acidification is a myth

why would that be?

 

[hellopunyhumans]

Because there is no measure of this before 100 or less years ago so no one knows how this fluctuates

You aren't aware that marine shell fossils go back more than 500 million years?

 

[hellopunyhumans]

Fossils are rock, they are not the creature, so they do not determine ocean acid levels

Hold up there.

"Micropaleontologist Elisabetta Erba of the University of Milan in Italy, and geochemist Helmut Weissert of the Swiss Federal Institute of Technology in Zürich, Switzerland, wanted to gauge how the high acidity affected the ancient marine ecosystem. They examined fossils from ancient ocean sediments at two drill sites—one from a now-above-ground formation in northern Italy and the other from deep water in the mid-Pacific Ocean. "The Pacific Ocean was the only big ocean at that time," Erba says. In particular, they studied the numbers and condition of fossilized specimens of calcareous nannoplankton, the microscopic ancestors of modern plankton. The creatures' shells consist mostly of CaCO3 and therefore could reveal their overall health and the state of the ocean's chemistry. "
