Researchers sampled sediment cores and found that where magnetite was abundant, methane-producing bacteria were as well.
Oceans
Ocean Impacts on European Winter Weather
State-of-the-art high-resolution models are needed to reveal the ocean’s role in driving extra-tropical weather systems.
Reactive Barriers Could Keep Nitrate out of the Atlantic
Microbes in mulch scrub nitrate from groundwater before it flows to the sea.
Physics + Machine Learning Provide a Better Map of Ocean Measurements
A new study offers a compelling example where the merger of dynamical modeling, machine learning, and ocean measurements enhances oceanographic understanding, monitoring, and mapping.
The Tonga Eruption Left Deep-Sea Life Buried in Ash
When Hunga erupted in 2022, ash “decimated” slow-moving species living on the seafloor. More mobile species were able to hoof it out of harm’s way.
In Hot Water and Beyond: Marine Extremes Escalate
A new study suggests marine life is increasingly faced with triple-threat events in which extreme water temperature, low oxygen levels, and acidification converge.
Radar Data Show Thwaites Gets a Daily Bath of Warm Seawater
The Doomsday Glacier, predicted to raise global sea level by more than half a meter, could be exposed to more warm ocean water than previously thought.
Dual Tsunami Generation from Atmospheric and Oceanic Sources
The 2022 Tonga volcanic eruption generated waves that propagated across the Pacific Ocean. A new analysis of sea level measurements is used to dissect the difference in wave components from two sources.
Radioactive Isotopes Trace Hidden Arctic Currents
Tracing anthropogenic radionuclides shows researchers how water from the Atlantic flows into and mingles with Arctic currents.
