Shades of a Canfield Ocean — Hydrogen Sulfide in Oregon’s Purple Waves? [View all]

[Binkie The Clown]

Are we already starting to awaken some of the horrors of the ancient hothouse ocean? Are dangerous, sea and land life killing, strains of primordial hydrogen sulfide producing bacteria starting to show up in the increasingly warm and oxygen-starved waters of the US West Coast? This week’s disturbing new reports of odd-smelling, purple-colored waves appearing along the Oregon coastline are a sign that it may be starting to happen.

The purple sulfur reducing bacteria, though not dangerous themselves, live in a kind of conjoined relationship with the much more deadly hydrogen sulfide producing bacteria. The purple, is therefore, a tell-tale of the more deadly bacteria’s presence. And hydrogen sulfide producing bacteria may well be the most dangerous organism ever to have existed on the planet — largely responsible for almost all the great extinction events in Earth’s deep history. For hydrogen sulfide itself is directly toxic to both land and ocean-based life. Its deadly effects are increased at higher temperatures. And not only is it directly toxic in both water and air, if it enters the upper atmosphere it also destroys the ozone layer.
