The Canfield Ocean model was proposed by geochemist Donald Canfield to explain the composition of the ocean in the middle to late Proterozoic. == History == In a paper published in 1998 in Nature, Canfield argued that the deep ocean was anoxic and sulfidic (also known as euxinic) during the time of the Boring Billion (1.8–0.8 billion years ago, Gya), and that those conditions ceased the mineral deposition of iron-rich banded iron formations (BIF) in ocean sediments.
