In July, the science journal Nature Geoscience published a groundbreaking paper describing evidence that large amounts of free oxygen is produced chemically on the deep floor of the Pacific Ocean.  Led by Scottish Association for Marine Science researcher Andrew K. Sweetman, the discovery of so-called “dark oxygen” has the potential to completely upend much of what we think we know about how oxygen gets into the atmosphere.  But a funny thing happened shortly after the study came out, when one of the research funders – an undersea mining company – got cold feet.  Canadian Broadcasting Corporation environmental reporter Inayat Singh broke the story, and he spoke to Monday Buzz host Brian Standing.
