Inside and Out

Ocean acidification has been studied in relation to marine animals with calcium carbonate shells. Oysters, sea butterflies, shrimp – all are affected by acidification when their outer shells don’t develop properly. According to this article, ocean acidification has increased by 25-30% since the beginning of the Industrial Revolution. A new study¬†published in Nature Climate Change…

Larger Than Life

When one thinks of marine life, especially when it comes to endangered marine life, the mind naturally turns to the poster children of conservation: polar bears, whales, dolphins. The big guys. Maybe some of us think of our favorite fish – tuna, for example, or salmon. Not many spare a thought for the tiny shelled…

Krill Gratitude

Massive ocean krill swarms – hundreds of millions of tons of them – are a keystone of one of the great planetary life cycles. A new Australian study published in the journal Nature Climate Change¬†called Risk maps for Antarctic krill under projected Southern Ocean acidification, looks at the threshold at which krill – specifically, their…

That Sinking Feeling

I’ve written here and here about carbonate organisms which are sensitive to raised levels of acidity in water and rain. Everyone knows the effects of acid rain on trees. Until recently, though, I hadn’t given much thought to the effects of acid rain on rock formations. Specifically, on the porous limestone that underlies much of…
