- Canfield_ocean abstract "The Canfield Ocean model refers to the Ocean composition theorized by geologist Donald Canfield. In a seminal paper in Nature in 1998, Canfield argued that the Ocean had become partially anoxic and sulfidic, causing mass extinction.Peter Ward studies the effects of ocean hypoxia(anoxic) and sulfidic oceans and climate change. He found warming of the ocean caused by a rise of carbon dioxide levels to about 1000 parts per million as a trigger for mass extinction.The term Strangelove ocean is a model name coined by a study published in 1985, which found a decrease in the δ13 C values of planktic skeletons following the Cretaceous–Paleogene extinction event, causing a homogenous ocean in decades or centuries, visible in the boundary sediment layer as a manifestation of the elimination in the surface-to-bottom carbon isotope gradient in ocean waters, the halt of ocean primary production. During a time when carbon fractionation by a photosynthesis-respiration mechanism became ineffective. It was later shown that the burial rate of terrestrial organic carbon (biological pump) was likely unaffected.".
