Thirty-seven years of observations reveal the meteorological conditions that lead to persistent, thick fast ice in Antarctica.
Oceans
Arctic Hydrothermal Vents May Resemble Those on Enceladus
By studying hydrogen-rich vent sites on Earth, scientists could learn more about the hidden ocean of Saturn’s icy moon—one of our solar system’s likeliest candidates for harboring life beyond Earth.
Satellite Measurements Make Major Seafloor Map Improvements
Though ship-based sounding has mapped some areas of the ocean floor in higher resolution, researchers have used SWOT data to create a detailed new map of the seafloor, including thousands of previously undetected small seamounts.
Mid-Ocean Ridges Could Be Dispersing Thermophilic Bacteria
Scientists suggest that two strains of endospores located more than 4,000 kilometers away from one another originated in the same place: along the Mid-Atlantic Ridge.
Coastlines Around the World Are Losing Sediment
A new tool maps coastal sediments on the basis of water color. It shows that 75% of the world’s coastlines may be losing suspended sediment.
Buried Tree Stumps Show Shoreline Shifts of the Outer Banks
Storms are unburying centuries-old stumps on North Carolina’s barrier islands. Researchers hope these long-gone forests can help land managers plan for the future.
The Survival of Arctic Sea Ice May Depend on Its Travel Routes
Researchers find that the motions of ice parcels determine which ones survive the annual summer melt.
Getting to the Bottom of Cenozoic Deep-Ocean Temperatures
Reconstructing past ocean conditions with oxygen isotopes could provide more information about how Earth’s climate evolved over time, but methods for reconstructing these data can yield varying results.
Characteristics of Moist Layers over the Tropical Atlantic
In a new study, characteristics of elevated moist layers, their seasonality, spatial distribution, structure, and the coupling of mid-tropospheric circulation and convection are examined over the tropical Atlantic.
La corriente de Florida podría estar desacelerándose, pero no por mucho
Una corrección necesaria a un conjunto de datos ampliamente utilizados redujo las estimaciones de los científicos de cómo se ha debilitado la circulación oceánica.
