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.
Remote-Controlled Ocean Drones Observe Atmospheric Cold Pools
Novel uncrewed sailing vehicles measured properties of atmospheric cold pools in hard-to-reach regions of the central and eastern tropical Pacific Ocean.
Subduction Initiation May Depend on a Tectonic Plate’s History
New seismic imaging study of the Puysegur Trench aims to solve one of the last major questions in plate tectonics.
Magma Pockets Lie Stacked Beneath Juan de Fuca Ridge
Analysis of new imaging data suggests that vertically stacked magma chambers are short-lived and contribute to eruptions.
Raising Central American Orography Improves Climate Simulation
Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.
Climate Clues from One of the Rainiest Places on Earth
One of the world’s rainiest places lies off Colombia’s Pacific coast. New field research sheds light on the Chocó low-level jet, a phenomenon responsible for the region’s precipitation.
A Deep Dive into Organic Carbon Distribution in Hadal Trenches
Researchers use sediment cores to study the amount and origin of sediment organic carbon in one of the least studied regions of the planet: hadal trenches.
Ocean Sensors Record Rare Triple Tsunami near New Zealand
A new suite of DART buoys in the South Pacific Ocean spotted waves set in motion by three tsunamigenic earthquakes that occurred within hours of one another.
