Melting Layer Characteristics of Cyclones
Dual‐frequency Precipitation Radar observations reveal the characteristics and microphysical processes of the melting layer in cyclone precipitation over the western North Pacific.
Layered Zone Beneath Coral Sea Suggests Ancient Magma Ocean
Scientists studying South Pacific earthquakes suggest that an ultralow-velocity zone at the core-mantle boundary may be a remnant of a molten early Earth.
The 2-Year Countdown to Deep-Sea Mining
A small island nation is forcing the hand of international regulators to finalize rules for deep-sea mining, but scientists say the environmental consequences are not yet clear.
Atmospheric Rivers Spur High-Tide Floods on U.S. West Coast
Researchers analyzed 36 years of data to understand how atmospheric rivers and other factors drive chronic coastal flooding.
Atoll Seismometer Detection of Solitary Ocean Waves
Seismic recordings from the South China Sea indicate that subtle, daily tilting of shorelines due to passing internal ocean waves can be measured on land, promising new constraints on ocean dynamics.
Tropical Climate Change Is a Puzzle—Could Aerosols Be a Piece?
The eastern tropical Pacific Ocean hasn’t warmed as much as climate change models projected. A new study shows that aerosols in the atmosphere could be responsible.
First Report of Seismicity That Initiated in the Lower Mantle
A 4D back-projection method revealed that aftershocks of the 2015 earthquake beneath the Ogasawara (Bonin) Islands occurred as deep as about 750 kilometers.
Hydrothermal Vents May Add Ancient Carbon to Ocean Waters
Data from a long-distance research cruise provide new insights into carbon cycling in the eastern Pacific and Southern Oceans.
