How Compressible Are Salt Marshes? Unique Field Experiments Combined With Advanced Modeling Provide Novel Insights From the Venice Lagoon

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Coastal depositional environments, particularly salt marshes, are among the morphologies most vulnerable to relative sea‐level rise (RSLR). Their ability to withstand changing conditions is closely related to their capacity to accrete sediment, gaining elevation at a rate comparable to RSLR. Sedimentation, decomposition of organic remains, and

EDS Analysis for Petrology: A Probabilistic Framework With GPyEDS

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Microtextural and chemical data from minerals in igneous rocks are critical for unpacking and developing understanding of processes in magmatic systems. Recent advancements leveraging unsupervised machine learning methods offer novel approaches for phase classification without requiring prior knowledge of phases or chemistry.

A Pilot Investigation of the Hidden Communities Associated With Dryas octopetala L. (Rosaceae) in Svalbard Using DNA Metabarcoding

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
A single marker revealed a considerable diversity of organisms associate with Dryas octopetala. The rhizosphere contains more taxa than the phyllosphere. Some taxa are cited for the first time in the Svalbard Archipelago. The use of different DNA marker will increase diversity data in the Svalbard Archipelago.
