view of the fact that they are geographically adjacent to coasts and intense anthropogenic …

Direct observations indicate that the global ocean oxygen inventory is decreasing. Climate
models consistently confirm this decline and predict continuing and accelerating ocean …

The prokaryotic and eukaryotic microorganisms that drive the pelagic ocean's
biogeochemical cycles are currently facing an unprecedented set of comprehensive …

Metal dissolution from atmospheric aerosol deposition to the oceans is important in
enhancing and inhibiting phytoplankton growth rates and modifying plankton community …

Oxygen loss in the ocean, termed deoxygenation, is a major consequence of climate change
and is exacerbated by other aspects of global change. An average global loss of 2% or more …
