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

Climate change, rising atmospheric carbon dioxide, excess nutrient inputs, and pollution in
its many forms are fundamentally altering the chemistry of the ocean, often on a global scale …

Ocean models predict a decline in the dissolved oxygen inventory of the global ocean of one
to seven per cent by the year 2100, caused by a combination of a warming-induced decline …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Abstract Changes in temperature, oxygen content and other ocean biogeochemical
properties directly affect the ecophysiology of marine water-breathing organisms,,. Previous …

Water masses can become undersaturated with oxygen when natural processes alone or in
combination with anthropogenic processes produce enough organic carbon that is …

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 …

Ocean ecosystems are increasingly stressed by human-induced changes of their physical,
chemical and biological environment. Among these changes, warming, acidification …

Ocean warming and increased stratification of the upper ocean caused by global climate
change will likely lead to declines in dissolved O2 in the ocean interior (ocean …

In the coming decades and centuries, the ocean's biogeochemical cycles and ecosystems
will become increasingly stressed by at least three independent factors. Rising …
