Uncovering Ocean Mixed Layer Dynamics From the Sea Surface State

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Submesoscale dynamics strongly influence the upper ocean, regulating mixing, air–sea exchange, and vertical heat transport. The recent Surface Water and Ocean Topography mission provides unprecedented high‐resolution observations of sea surface height (SSH), yet linking these surface measurements to subsurface ocean dynamics remains ...

SWOT Water Surface Elevation in Herbaceous Wetlands of Florida's Everglades

Geophysical Research Letters
Observing water level variations in wetlands is important for tracking global water and carbon cycles. The Surface Water and Ocean Topography (SWOT) mission was launched to measure Earth's surface waters, but its performance in vegetated wetlands was ...

Impact of Alkali Treatment on Prosopis juliflora Bark as Filler in Poly Lactic Acid for Flexible Packaging Films

Engineering Reports, Volume 8, Issue 8, August 2026.
Alkali treatment of prosopis juli flora bark powder (PJBP) enhances its compatibility with PLA, enabling the fabrication of improved biofilms. Drying in a hot air oven yields homogenous, reinforced films with potential for sustainable packaging applications.

Petrogenesis and Tectonic Evolution of Cenozoic Magmatism in the Southernmost Northern Andes: Insights From Zircon Petrochronology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study integrates new zircon U–Pb ages, zircon εHf(t)–δ18O isotopic data, and whole‐rock geochemistry to refine the temporal and spatial framework of magmatism in the southern Northern Andes (SNA) from ∼65 to 6 Ma. The San Lucas, Catamayo, Portachuela, and Gonzanamá batholiths and magmatic suites, along with Late Miocene plutons, display ...

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 1–Model Development

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Only one quarter of the global ocean floor has been directly surveyed; the remaining three quarters are inferred from satellite altimeter‐derived gravity data using techniques developed in the 1990s. These classical methods correlate gravity anomalies with known depths and extrapolate bathymetry in unsounded regions.

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 2—Model Evaluation and Uncertainty Analysis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Despite millions of ship soundings, bathymetry from satellite derived gravity is still necessary to fill in approximately three quarters of the global oceans. The methods used to carry out this inference have not changed significantly since the 1990s; however new methodology involving Machine Learning (ML) improves the bathymetric predictions ...
