Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

BACKGROUND Oxygen concentrations in both the open ocean and coastal waters have
been declining since at least the middle of the 20th century. This oxygen loss, or …

Eutrophication, or excessive nutrient enrichment, threatens water resources across the
globe. We show that climate change–induced precipitation changes alone will substantially …

Abstract Concepts underpinning the planetary boundaries framework are being
incorporated into multilateral discussions on sustainability, influencing international …

Understanding how water and solutes enter and propagate through freshwater landscapes
in the Anthropocene is critical to protecting and restoring aquatic ecosystems and ensuring …

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

Agriculture and urbanization have disturbed three-quarters of global ice-free land surface,
delivering huge amounts of nitrogen and phosphorus to freshwater ecosystems. These …

Abstract Around 36,000 km3 of freshwater flows through rivers and estuarine ecosystems
and enter the world's coastal fishing regions every year. The flow of freshwater and …

Many marine organisms are exposed to decreasing O2 levels due to warming-induced
expansion of hypoxic zones and ocean deoxygenation (DeO2). Nevertheless, effects of …

Anthropogenic stressors can alter the structure and functioning of infaunal communities,
which are key drivers of the carbon cycle in marine soft sediments. Nonetheless, the …
