Processes and Products of Turbidity Currents and Submarine Landslides in a Glacierized Fjord (Southwind Fjord, Baffin Island)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Sediment transported to fjords is redistributed by turbidity currents and sometimes fails on steep sidewall slopes, forming marine geohazards that are known to impact infrastructure. Since marine geohazards are poorly understood in Arctic Fjords due to lack of data and monitoring, a comprehensive study of Southwind Fjord, Baffin Island, was ...

Mantle Source Evolution Along the South Atlantic Transect (31°S) Records a Transition From HIMU Plume Component to Depleted MORB

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Interactions between mantle plumes and mid‐ocean ridges create considerable spatial variation in composition along ridge axes. What is less well known is the temporal variation in MORB compositions along single mantle flow lines. IODP Expeditions 390/393/390C/395E recovered basaltic basement from seven sites along a flow line, the South ...

Unearthing the Histories of Agrarian Landscapes: A Research Framework for Terraces as Sustainable Environments

Geoarchaeology, Volume 40, Issue 2, March/April 2025.
ABSTRACT This article presents an interdisciplinary programme for research on historic landscapes that has emerged since 2020 in the framework of the project Terraces as Sustainable Agricultural Environments (‘TerraSAgE’). While the methodology has been tested in specific Mediterranean case studies, it is also applicable in other locations and regions.
