Lagos longevos cuentan una historia sobre el agua en Marte
Imágenes de alta resolución de paleolagos recientemente descubiertos en Marte demuestran un período de su historia con flujo de agua constante.
Small-Scale Convection Shuffles the Oceanic Lithosphere
Seafloor spreading organized lithospheric minerals into a lattice, but small-scale convection jumbled up the innermost layer.
How Much Greenhouse Gas Do Tropical Soils Emit?
New research found that tropical soils emit nitrogen mostly as inert dinitrogen rather than as greenhouse gases.
To Estimate Plant Water Use, Consider the Xylem
New research shows that chemical isotopes from plant xylem can improve representations of the forest water cycle.
Long-Lived Lakes Reveal a History of Water on Mars
High-resolution imagery of newly discovered paleolakes shows a period of consistent liquid water flow.
Exploring a Warm Water Inflow Below an Antarctic Ice Shelf
Researchers guided an autonomous underwater submarine to capture the first direct observations of a warm water current flowing in below the Filchner-Ronne Ice Shelf in Antarctica.
When Winds and Currents Align, Ocean Mixing Goes Deep
Slantwise convection in the Irminger Sea off Greenland appears to mix ocean water to deeper depths than previously thought, representing an important contribution to Atlantic overturning.
