Investigating Query by Committee and Inverse‐Distance Based Exploration for Active Learning as Learning Strategies: An Application in Wood Dating

Quality and Reliability Engineering International, Volume 42, Issue 1, Page 66-79, February 2026.
ABSTRACT Fourier transform infrared (FTIR) spectroscopy, a non‐destructive method, is capable of measuring changes in the major wood components cellulose, hemicellulose and lignin during degradation. Previous research evaluated the application of supervised machine learning based on molecular decay over specific preservation conditions, achieving a ...

Orbital Variability in Grazing Proportion: New Insights From Sedimentary Amino Acid δ15N Records of the Western Equatorial Pacific

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The carbon sequestration capacity of the biological carbon pump (BCP) is determined by surface ocean carbon fixation and the transportation of fixed carbon to the ocean interior, which is closely linked to the trophic structure of planktonic ecosystem.

Shape Matters: Unlocking Transport Histories in Fine‐Grained Aeolian Sediments With Endmember Modeling of Size–Shape Distributions

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The transport medium, mode, energy, and distance are recorded in the grain‐size and grain‐shape distributions in a sedimentary deposit. While grain‐size analysis has long been used in sedimentology, grain‐shape analysis is increasingly recognized as a valuable tool for reconstructing sedimentary processes and palaeoenvironments.

Bayesian Inference of Local Paleosecular Variation From Sparse Paleomagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We introduce a novel Bayesian method to construct local paleosecular variation (PSV) curves. By modeling the geomagnetic field as a Gaussian process, global models can be incorporated as informative prior distributions. Because we use Hamiltonian Monte‐Carlo methods, complex age distributions resulting for example from radiocarbon calibration ...

Spatial Variability in Deep SOC Storage in Georgia (USA) Salt Marshes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Coastal Georgia's (USA) salt marshes function as soil organic carbon (SOC) sinks because of their high primary productivity and slow decomposition rates. Quantifying SOC stocks is essential to establish a baseline for long‐term SOC trends and to highlight their capacity for long‐term carbon (C) sequestration.
