CO2 – Southern Fried Science

Fog Horn (A Call to Action)

It’s Native American History Month. Southern Fried Science recognizes that our servers are housed on the occupied land of the Timpanogos people while the majority of our writers live on unceded Powhatan territory. This November, Try Something New: Decolonize Your Mind.

Flotsam (what we’re obsessed with right now)

Boaters stumble on massive Caribbean “gyre” of plastic garbage. “Gyre is in quotes because I’m almost certain that this is debris from the 2017 Atlantic Hurricane season, rather than an accumulation of decades of plastic is a circulating ocean current. It’s still shocking to see.

The ARA San Juan, one or Argentina’s two diesel-electric submarines, is missing. Search and rescue is mobilizing and there’s hints that the sailors tried to send out a signal Saturday.

You have probably heard that as the global climate changes due to human influence the sea surface is going to rise and the oceans will get warmer and more acidic. The bit about the oceans increasing in acidity is particularly troubling because it implies calcium carbonate based organisms (oysters, snails, corals, etc.) will simply dissolve in this future dystopian acid-ocean (that is a bit of an oversimplification, but you get the idea).

Ocean acidity is determined by measuring the pH, which relates acidity based on the number of hydrogen ions found in the water. So long story short, as more and more carbon dioxide (CO2) is emitted into the atmosphere, it in-turn fluxes into the oceans forming carbonic acid which results in the release of hydrogen ions lowering the pH. Simple logic would suggest that this spells bad news for calcifying organism (poor Mr. Snail).
