Global Detection and Morphological Characterization of Seamounts With Weakly Supervised Deep Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Seamounts are submarine volcanic features that record the tectonic and magmatic evolution of Earth's interior, yet their global distribution remains poorly resolved due to sparse high‐resolution bathymetric coverage. We present a weakly supervised deep learning framework that integrates gravity and bathymetric data to enable global‐scale ...

Geodetic analysis of Skylab altimetry preliminary data - SL/2 EREP pass 9 [PDF]

open access: yes
The author has identified the following significant results. The analysis was based on a time series intrinsic relationship between the satellite ephemeris, altimeter measured ranges, and the corresponding a priori values of subsatellite geoidal heights.

Principled Fourier Neural Operators for High‐Resolution Regional Ocean Modeling

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Reliable and computationally efficient ocean state forecasts are essential for climate resilience, maritime safety, and science‐to‐decision applications. Growing demand has stimulated interest in machine learning approaches as scalable complements to traditional numerical models.

The application of Skylab altimetry to marine geoid determination [PDF]

open access: yes
The author had identified the following significant results. The major results can be divided broadly into two groups. One group is concerned with the effects of errors inherent in the various input data, such as the orbit emphemeris, a priori geoid etc.

A High‐Accuracy TEC Model for Low‐Mid Latitudes Using a BWO‐Optimized CNN‐xLSTM Hybrid Model With Multi‐Instrument Data Fusion

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract The total electron content (TEC) in the ionosphere is strongly affected by solar activity and geomagnetic disturbances in mid‐ and low‐latitude regions, making it a major source of error in GNSS navigation and communication systems. To improve the prediction accuracy of ionospheric TEC, this study proposes a deep learning model—Beluga Whale ...

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Bayesian perspective for orientation determination in cryo‐EM with application to structural heterogeneity analysis

open access: yesActa Crystallographica Section D, Volume 82, Issue 4, Page 274-294, April 2026.
A Bayesian perspective on orientation estimation in cryo‐EM is presented, with the minimum mean‐square error estimator outperforming standard cross‐correlation‐based approaches, particularly under challenging low signal‐to‐noise conditions. We demonstrate that improved orientation estimation has a decisive impact on 3D reconstruction quality and ...

Exploring the Metric Systems of Medieval New Towns in Central Europe: Reconstruction of Urban Plot Scheme Using Cosine Quantogram and Modular Analysis

open access: yesArchaeometry, Volume 68, Issue 2, Page 173-183, April 2026.
ABSTRACT This study examines plot divisions and units of measurement in regular medieval new towns in Central Europe, with a particular focus on historical Silesia. By applying the cosine quantogram method alongside GIS‐referenced cartographic sources and modular analysis, the research reconstructs the spatial organization of urban layouts. The results

Rethinking network embeddedness in international business: A review and view in space and time

open access: yesInternational Journal of Management Reviews, Volume 28, Issue 2, April 2026.
Abstract Conceptual and empirical contributions to network embeddedness have flourished in the last decades within the field of international business (IB). Scholars have used the concept to explain IB phenomena through the lens of business actors’ network relationships and positions in their networks.

Golden Gate Bridge, as Always? Eliciting Prototypical Places From Autoregressive Large Language Models via Category Production

open access: yesTransactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT Among the various theories of categorization, Eleanor Rosch's prototype theory stands out as both influential and contested. In contrast to the classical theory of concepts, prototype theory posits that humans conceptualize the world using category structures where exemplars vary in their degree of membership.
