Ocean deoxygenation is predicted to threaten marine ecosystems globally. However, current
and future oxygen concentrations and the occurrence of hypoxic events on coral reefs …

Oxygen is crucial for the survival of marine species. Yet, the ocean has experienced a loss of
approximately 2% of its oxygen inventory since the last century, resulting in adverse impacts …

The ocean is the main heat reservoir in Earth's climate system, absorbing most of the top-of-
the-atmosphere excess radiation. As the climate warms, anomalously warm and fresh ocean …

Abstract In 2017, more than 15,000 scientists from 184 countries signed a second warning
letter to humanity to caution against our continued wholesale destruction of global …

Coastal eutrophication and hypoxia remain a persistent environmental crisis despite the
great efforts to reduce nutrient loading and mitigate associated environmental damages …

Sedimentary molybdenum (Mo) and uranium (U) enrichments are widely used to reconstruct
changes in bottom water oxygen conditions in aquatic environments. Until now, most studies …

Over a decade ago, oceanographers began installing oxygen sensors on Argo floats to be
deployed throughout the world ocean with the express objective of better constraining trends …

Global ocean O2 content has varied significantly across the eons, both shaping and being
shaped by the evolutionary history of life on planet Earth. Indeed, past O2 fluctuations have …

Ocean temperature and dissolved oxygen shape marine habitats in an interplay with
species' physiological characteristics. Therefore, the observed and projected warming and …

As human activities release increasingly more fossil fuel-derived emissions directly into the
atmosphere, terrestrial, aquatic, or marine ecosystems, the biomagnification and …
