A high-resolution regional model of the Southern Ocean reveals how topographically induced mixing in the abyss is important in creating the water masses that can upwell back up to the surface.

How Nutrients Get Back Up to the Surface Ocean
A new dual isotope tracer technique is used to assess the role of a number of poorly understood nutrient supply mechanisms fueling biological productivity in the ocean.
A Wider and Deeper View of Jupiter’s Jets
The mid-latitude jets on Jupiter are driven by turbulence that arises, in part, from deep cells, consistent with Juno microwave and gravity observations.
Do Some Cratons Have Soggy Bottoms?
Long-persistent stable cratons bear much of the deep-time geologic record, and a new study combines seismic and petrological data to reveal how interactions with mantle fluids can shape their evolution.
Nutrients at Depth Can Be Uplifted by the Kuroshio Large Meander
Aperiodic, southward deflection of the Kuroshio, a.k.a. the Kuroshio large meander, uplifts the nutrients in deep layers to induce offshore phytoplankton bloom.
ENSO Variations Modulate the Kuroshio in the East China Sea
Recent warm El Niño Southern Oscillation events strengthened winds over the western Subtropical North Pacific, leading to planetary waves with cyclonic eddies, weakening the Kuroshio in the East China Sea.
Urban Greening Could Help Achieve Carbon Neutrality Goals
A new modeling framework highlights that urban greening is a sustainable solution to achieve environmental co-benefits in mitigating heat and carbon emissions.
Sulfur is Demanding its Place in Crop Nutrient Budgeting
Scientists advocate for a more significant consideration of sulfur from a multidisciplinary perspective as a necessary step towards sustainable crop management.
Revealing a Catchment’s Erosional Secrets: Grain Size Matters
A provenance study with 699 new samples from 12 different sediment grain sizes (from sand to boulder) shows that each fraction originates from distinct parts of a mountain catchment in California.
A Crystal Ball for the Carbon Cycle, But a Cloudy One
Carbon cycle models quantify relationships between emission scenarios and resulting atmospheric concentrations, but are the projections credible? New analyses find grounds for both hope and concern.
