Duration and Geochemical Evolution of Triassic and Jurassic Magmatism Along the Eastern North American Margin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract Our understanding of the impact of melt generation and the interplay between magmatism and mechanical stretching during progressive rifting leading to seafloor spreading remains rudimentary. The Eastern North American Margin (ENAM) provides an excellent location to study the influence of rift magmatism on continental break‐up considering the ...

Lava Lake Spattering Drives Seismic Tremor During the Geldingadalir 2021 Eruption, Iceland

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract Volcanic eruptions generate a continuous ground motion that is commonly referred to as tremor. Although tremor is used worldwide for real‐time monitoring of volcanoes, the mechanisms involved are generally poorly understood. Here, we study the episodic effusion during 2021 Geldingadalir eruption. We use photogrammetric data and videos acquired

Direct Pathways From the Drake Passage to the South Atlantic Subtropical Gyre

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract Lagrangian simulations based on 18 years (2002–2019) of high‐resolution thermohaline and three‐dimensional velocity fields allow revisiting the fate and thermohaline changes of the upper‐ocean Antarctic Circumpolar Current (ACC) waters that enter directly the South Atlantic Ocean basin.

Multi‐Scale Variability of Blue Carbon in Seagrass Sediments From Three California Estuaries

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract Seagrass meadows are a significant global carbon sink. Most of the carbon sequestered in these ecosystems is found as sedimentary organic carbon, which can vary spatially across seagrass meadows and can be derived from a variety of sources. Here, we investigate intra‐ and inter‐meadow spatial variability in sediment organic carbon storage and ...
