Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Tile drainage is widely adopted in the U.S. Midwest to manage excess soil water and sustain agricultural productivity, yet its impact on key water budget components—particularly evapotranspiration (ET)—remains insufficiently understood under varying drainage designs and climate conditions.

A note on frame transformations with applications to geodetic datums [PDF]
GPS Solutions, 2003 Rigorous equations in compact symbolic matrix notation are introduced to transform coordinates and velocities between ITRF frames and modern GPS-based geocentric geodetic datums. The theory is general but, after neglecting higher than second-order terms, it is shown that the equations revert to the formulation currently applied in most major ...

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data
AGU Advances, Volume 7, Issue 6, September 2026.Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Transformation of GPS measurements in the Koice hollow into the national geodetic grid [PDF]
Acta Montanistica Slovaca, 1999 The paper deals with transformation procedures observed GPS (Global Positioning System) data from the World Geodetic System WGS-84 into the national grid datum S-JTSK and Bpv. GPS measurements are realized on the geodetic network in the Koice-hollow for

Warming and Sea‐Level Rise Transform Intertidal Sediment Thermal Dynamics
Earth's Future, Volume 14, Issue 9, September 2026.Abstract Intertidal sediments are important hotspots in coastal ecology and biogeochemistry. Their function and ecology are strongly controlled by temperature, yet the impact of future climate warming and sea‐level rise (SLR) on their thermal dynamics remains unquantified.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Megathrust slip behavior in subduction zones can vary along‐strike, yet the mechanisms driving this variability remain uncertain. The Middle America trench offshore Mexico provides an ideal setting to investigate the structural controls on megathrust slip behavior.

Magnetic Dual‐Layer Equivalent Sources on the Sphere
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The equivalent source method is widely used for processing and interpolating magnetic data, particularly in airborne surveys. However, implementations based on Cartesian coordinates present limitations at regional and global scales, where Earth curvature introduces geometric inconsistencies that affect data integration and modeling accuracy ...
