Distribution, Formation, and Evolution of Subsurface Secondary Acoustic Ducts From Global Ocean Modeling and Observations

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...

Spatiotemporal Variability in the Vertical Distribution of Phytoplankton Biomass in the Ice‐Free Southern Ocean: A Bioregionalization Approach

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract The Southern Ocean plays a major role in the global oceanic sink of carbon dioxide (CO2). However, substantial uncertainties remain regarding how phytoplankton production influences this carbon sink. Observations of the spatiotemporal variability in vertical phytoplankton biomass distribution are therefore essential to advance our ...

In Situ Carbonation of Sedimentary and Igneous Rocks of Ultramafic Composition in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Over 3.5 years of exploration in Jezero Crater, the Perseverance rover has explored several geological units of diverse origins and natures, performing multi‐technique remote analyses of the chemistry and mineralogy of rocks with the SuperCam instrument suite.

La ville et la justice spatiale

, 2012
L’EXPRESSION « JUSTICE SPATIALE » ne s’est diffusée que très récemment et, encore aujourd’hui, géographes et aménageurs ont tendance à éviter l’usage explicite de l’adjectif « spatial » lorsqu’ils analysent la quête de nos sociétés contemporaines pour ...

Amapari Marker Band Metal‐Enrichments: Potential Mechanisms and Implications for Surface and Subsurface Water and Weathering in Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract NASA's Curiosity rover is exploring a 5 km tall sedimentary mound that is hypothesized to record the transition from a warm and wet (phyllosilicate‐rich) to a cold and drier (sulfate‐rich) Mars. Evidence of magnesium sulfate‐bearing rock has shown that Curiosity has crossed through this phyllosilicate‐sulfate transition.

Superposed Epoch Analysis of Extreme Geomagnetic Disturbances at Auroral Zone Latitudes Over a Solar Cycle

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Intense and rapidly changing electrical currents in near‐Earth space produce geomagnetic disturbances (GMDs) with large magnetic field rates of change (dB/dt) and in turn large geomagnetically induced currents (GICs) in nearby power lines and pipelines. This study builds on the work of Engebretson, Yang, et al.
