A rare whole-lake experiment suggests that in some cases, low-oxygen conditions may have a smaller impact on methane release to the atmosphere than previously thought.
Researchers used deep learning to fill in the gaps of “patchy” water quality data, revealing decades-long trends toward warmer and less oxygenated rivers that could have worrisome consequences.
The ancient glaciers hint at an Archaean Earth that may have looked similar in some ways to our own time.
A global study found dangerously low levels of dissolved oxygen in rivers around the world. The true prevalence of hypoxia is probably even higher.
Manganese oxides are thought to be a signature of atmospheric oxygen. But on the Red Planet, recent results suggest they might be more of a red herring.
Respiration quotients in the Atlantic and Pacific Oceans reflect different water temperature, nutrient stress and phytoplankton community structure, important for regional carbon and oxygen cycling.
Elevated copper isotope ratios in arc magmas from fluid-rich cold subduction zones support the role of oxidizing fluids from the subducted lithospheric serpentinite in the oxidization of arc magmas.
New research provides a 200-year reconstruction of interannual rainfall in the Amazon basin using oxygen isotopes preserved in tree rings in Ecuador and Bolivia.
Laboratory experiments show that earthquakes may have helped early life evolve in an oxygen-free world.
A new study looks at habitat reduction during low-oxygen events, spurring the question, Could short-term events provide a window into the long-term health of oceans?
