High‐Precision Delineation of Curie Point Depth Under Remanent Magnetization Using Physics‐Informed Neural Networks

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Curie point depth (CPD), a key indicator of the lithosphere's thermal structure, is typically estimated using spectral analysis or interface inversion methods. However, these approaches often neglect the effects of remanent magnetization, leading to substantial uncertainty.

Regional‐to‐Global Tectonic and Trench‐Morphology Effects of Oceanic Plateau Subduction

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Regional geodynamic modeling has shown that oceanic plateau subduction can modify the slab behavior. However, few studies have explored these interactions beyond 100 Myr in 3‐D spherical models. Using 3‐D spherical mantle convection models with self‐consistent plate‐like behavior, we investigate how the geometry and rheological properties of ...

Geoid anomalies and fracture zones in the Pacific Ocean [PDF]

The high degree and order geoid field in the Pacific is a superposition of fracture zone anomalies and hot-spot swell anomalies. A two-dimensional spectral analysis of this field reveals a very strong north-south wavenumber contribution with a dominant ...

Tracking interannual variation of a large‐scale ocean front influences foraging in a mesopelagic predator

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Macroscale ocean fronts aggregate significant biomass and provide critical foraging habitat for large marine predators. These frontal systems shift in response to ocean climate variation, including basin‐scale oscillations, and the degree to which marine predators track these movements affects their foraging and reproductive success. Using two

Converting NAD83 GPS heights into NAVD88 elevations with LVGEOID, a hybrid geoid height model for the Long Valley volcanic region, California [PDF]

, 2008
A GPS survey of leveling benchmarks done in Long Valley Caldera in 1999 showed that the application of the National Geodetic Survey (NGS) geoid model GEOID99 to tie GPS heights to historical leveling measurements would significantly underestimate the

DASNordicSLR—A Regional Dataset of Sea Level Projections for Northern Europe

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Relative sea level projections for Northern Europe (DASNordicSLR) combine IPCC‐AR6 projections with vertical land motion data from NKG2016LU. The resulting high‐resolution dataset enables a realistic representation of regional sea level change along coastlines, supporting climate services and coastal risk assessments with spatially detailed insights ...

A methodology for least-squares local quasi-geoid modelling using a noisy satellite-only gravity field model

Journal of Geodesy, 2018
The paper is about a methodology to combine a noisy satellite-only global gravity field model (GGM) with other noisy datasets to estimate a local quasi-geoid model using weighted least-squares techniques. In this way, we attempt to improve the quality of
