Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

Boreas, EarlyView.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.

Making with the Trouble: Un/Enfolding Posthuman Participants with Young People in Creative Post‐Qualitative Research

International Journal of Art &Design Education, EarlyView.
Abstract This paper explores how ‘what matters’ can surface in multisensory arts‐informed projects as ways for young people to survive and stay with gender and sexuality troubles that are always more than theirs. Situated in an ex‐mining post‐industrial locale, we make an agential cut in a longitudinal research and engagement project called Unboxing ...

Bayesian Optimization in Bioprocess Engineering—Where Do We Stand Today?

Biotechnology and Bioengineering, Volume 122, Issue 6, Page 1313-1325, June 2025.
ABSTRACT Bayesian optimization is a stochastic, global black‐box optimization algorithm. By combining Machine Learning with decision‐making, the algorithm can optimally utilize information gained during experimentation to plan further experiments—while balancing exploration and exploitation.

Assessing Groundwater Potential in the Ziway Lake Watershed Using Geographical Information System, Analytic Hierarchy Process, and Drinking Water Quality Index

Global Challenges, Volume 9, Issue 6, June 2025.
This study identifies groundwater potential zones in Ethiopia’s Ziway Lake watershed using GIS and the SWAT model. Over half the area shows moderate to very high potential. Nearly 40% of high‐potential zones also have good to excellent water quality. The results offer a practical tool for sustainable groundwater management, with potential application ...

Origin of Silicic Magmatism at the Katla Volcanic Complex, South Iceland

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract The Katla volcano is a bimodal caldera complex within Iceland's basalt‐dominated Eastern Volcanic Zone. To unravel the petrogenesis of silica‐rich rocks from Katla, we provide new δ18O values for almost 60 basaltic, intermediate, and high‐silica eruptive rocks, including a number of partially melted felsic xenoliths.

Tectonic Setting and Evolution of Anatectic Melt Composition During Prograde Metamorphism up to UHT Metamorphism: Constraints From P–T–t–Melting Path From Rundvågshetta, Lützow–Holm Complex, East Antarctica

Journal of Metamorphic Geology, Volume 43, Issue 5, Page 467-495, June 2025.
ABSTRACT The pressure–temperature–time (P–T–t) evolution of a metapelitic ultrahigh‐temperature (UHT) granulite from Rundvågshetta (Lützow–Holm Complex, East Antarctica) and chemical evolution of partial melt during the prograde metamorphism up to UHT metamorphism are studied in detail.

Effects of Subduction Fluids and Fractional Crystallization on the Magnetic Minerals Formation in the Back‐Arc Basin

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract (Titano)magnetite is the major magnetic carrier in igneous rocks, whether it can decode the influence of subduction fluids and fractional crystallization characteristics in back‐arc basins is unclear. Here, we performed petrographic and magnetic analyses on volcanic samples from the Okinawa Trough, with titanomagnetite as the dominant magnetic
