Evolution of ocean oxygen deficient zones during the Miocene: insights from and for the I/Ca paleo-oxygenation proxy ...
In recent decades, the oceans have been losing oxygen at a rate of >~2% per decade, with the largest effect in already low oxygen shallow-water areas called oxygen deficient zones (ODZs). This threatens marine ecosystems, including fish that billions of people rely on for food and economic stabil...

In recent decades, the oceans have been losing oxygen at a rate of >~2% per decade, with the largest effect in already low oxygen shallow-water areas called oxygen deficient zones (ODZs).

Understanding how ocean oxygenation will change with continued climate change is therefore vital. Models agree that deoxygenation will continue to at least the year 2100, but beyond this have not reached a consensus.
