Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Measuring and mapping vegetation structure is essential for understanding the functioning of terrestrial ecosystems and for informing environmental policies. Recent years have seen a growing demand for high‐resolution data on vegetation structure, driving their prediction at fine resolutions (1–30 m) at state, continental, and global spatial ...

The THEMIS Control Network of Mars
Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract The accurate co‐registration of geospatial data is necessary to answer questions that cross‐cut disciplines and are key to understanding fundamental questions about our Solar System. To address this need and provide an updated product for Mars that is tied to a common reference frame, we have photogrammetrically controlled Thermal Emission ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Bulk (whole sample) magnetic properties of three‐hundred‐sixty‐two samples from five North Atlantic Ocean sediment cores are compared to the magnetic properties of five grain‐size fractions separated from the same samples. The relative abundance and magnetic properties of the size fractions are highly variable both within a core and among ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Natural volcanic glasses are well represented in the geologic record, and typically contain near‐ideal single‐domain particles required for standard Thellier‐type absolute paleointensity experiments. Young (<∼50–100 ka) glasses have been demonstrated to reliably record Earth's magnetic field.

Space Chicken: A Historical Look at How the Critical Path Changes over a Missions Development [PDF]
The critical path in schedule analysis defines the series of tasks that have no schedule slack leading to the delivery of a system. The critical path for NASA science missions, which typically runs through a spacecraft subsystem or a scientific ...

Brunhes Paleomagnetic Directions and Paleointensities From Northern Hainan Island
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Paleomagnetic studies typically assume that the long‐term, time‐averaged geomagnetic field behaves as a geocentric axial dipole (GAD). While paleodirectional data over the past five million years generally agree with GAD predictions, mid‐to‐low latitude paleointensity records fail to show GAD, with high values from Hawaii.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Mantle‐derived magma flux has a first‐order control on long‐term volcanic productivity, volatile cycling, and crustal growth in convergent margins. However, the factors controlling it remain unclear. We used a simplified, 3D conceptualization of an intraoceanic subduction zone and petrologic constraints on mantle melting to calculate mantle ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Dissolved neodymium (Nd) isotopes are key tracers for water mass mixing in the open ocean and for land‐ocean exchanges in marginal seas. Hydrogenous Nd isotope ratios (expressed as εNd) in cores north of the equator reflect values of the surrounding lithology and tend to vary in accordance with local rainfall records, indicating higher ...
