A Global Evaluation of Lithology‐Dependent Marine Sediment Compaction Parameters and Their Uncertainties

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Tectonic subsidence, sea level, and paleoclimate reconstructions using marine records rely on accurate decompaction of the sediment column. Over time, increased overburden pressure from burial decreases sediment porosity with depth. The porosity‐depth relationship is lithology‐dependent and can be represented by an exponential function ...

Intense Isopycnal Stirring and Double‐Diffusion Contributing to Microscale Variance in the Kuroshio Extension Front

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract In oceanic frontal regions, isopycnal stirring induces lateral thermohaline intrusion. Previous studies have observed interleaving layers in the Izu Ridge and Kuroshio Extension attributed to isopycnal stirring driven by mesoscale eddies and submesoscale flows.

Direct Observations of Strong Jets Transporting Deep and Bottom Water Into the Indian Ocean Through the Fracture Zones of the Southwest Indian Ridge

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The Indian Ocean plays a crucial role in the abyssal overturning circulation, transforming Antarctic Bottom Water (AABW) into lighter water. In the western Indian Ocean, the only path for AABW to reach the subtropics as part of the global overturning is through the fracture zones of the Southwest Indian Ridge.

Rethinking Seawater Mo Isotope Mass‐Balance and the Sedimentary Mo Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract A lingering misconception is that seawater 98Mo/95Mo ratios should have increased more or less linearly with the oxygenation of Earth's oceans. At the root of this hypothesis is the generalization that oxidizing marine sediments have a stronger affinity for lighter‐mass Mo isotopes than their reducing counterparts.

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea

Journal of Animal Ecology, Volume 95, Issue 3, Page 443-454, March 2026.
Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...
