Submarine Flank Collapses at Tagoro Volcano: Insights From Bathymetric Surveys and 3D Multiphase Simulations

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.

Transient Ecological Niches for Diazotrophs in Upwelling Bays

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18

Long‐term reduction of invasive killer shrimp (Dikerogammarus villosus) density following removal of zebra mussel (Dreissena polymorpha) shells and coarse substrate on UK lake beds

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Working with Citizen Scientists, researchers tested manual removal of coarse cobbles and zebra mussel shells from fine‐sediment lake beds to reduce invasive killer shrimp densities. Killer shrimp use these features for habitat, and after clearing them from 3 × 3 m sections of lakebed, killer shrimp densities were reduced by over 90% in these sections ...

Tunable Porosity and Structural Properties of Carbon Aerogels: Adapting Packing Density and Morphology of Dry‐Film Cathodes

open access: yesBatteries &Supercaps, Volume 9, Issue 7, July 2026.
Two types of carbon aerogels (CAs) were evaluated as sulfur hosts in lithium‐sulfur solid‐state batteries: a brittle mesoporous (p‐CA) and flexible macro‐/microporous (f‐CA). p‐CA achieves very high sulfur utilization (∼1500 mAh gS−1), but poor Coulombic efficiency and reversibility; f‐CA offered better cycling stability, but lower sulfur utilization ...
