Underwater Acoustic Nonlinear Blind Ship Noise Separation Using Recurrent Attention Neural Networks

Remote Sensing
Ship-radiated noise is the main basis for ship detection in underwater acoustic environments. Due to the increasing human activity in the ocean, the captured ship noise is usually mixed with or covered by other signals or noise. On the other hand, due to

3D‐Printed Na3V2(PO4)3 Electrodes for Symmetric Sodium‐Ion Batteries

Small Structures, Volume 7, Issue 6, June 2026.
Vat photopolymerization 3D printing is used to fabricate current collector‐free Na3V2(PO4)3 (NVP) electrodes with complex lattice geometries. After thermal postprocessing, the printed electrodes operate reversibly as both positive and negative electrodes in a symmetric sodium‐ion battery.

Spectral‐Resolved Light at Night: TEMPO Observations and Background Correction

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Artificial Light at Night (ALAN) poses risks to public health and ecosystems. While long‐term remote sensing has tracked global nighttime light, spectrally resolved light at night (spectral light at night (SLAN)) data from geostationary orbit only became available with NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission.

Underwater Acoustic Target Recognition Based on Sub-Regional Feature Enhancement and Multi-Activated Channel Aggregation

Journal of Marine Science and Engineering
Feature selection and fusion in ship radiated noise-based underwater target recognition have remained challenging tasks. This paper proposes a novel feature extraction method based on multi-dimensional feature selection and fusion. Redundant features are

A Top‐Down View of Global and Regional Carbon Budgets From an Ensemble of Atmospheric Inversions

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Atmospheric inversions provide surface CO2 flux estimates based on in situ observed atmospheric CO2 mole fractions or satellite‐based column average CO2 (XCO2). Here, we provide a detailed assessment of 14 atmospheric CO2 inversions included in the Global Carbon Budget (GCB2024).

Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes. As such, an increasing number of studies couple monitoring data with petrological tools to obtain insights into the causes and durations of magmatic processes. The 2018–2020 eruption of the
