Why Are Plume Excess Temperatures Much Less Than the Temperature Drop Across the Lowermost‐Mantle Thermal Boundary Layer?

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract While temperature drop across the mantle's basal thermal boundary layer (TBL) is likely > ${ >} $1,000 K, the temperature anomaly of plumes believed to rise from that TBL is only up to a few hundred Kelvins. Reasons for that discrepancy are still poorly understood and a number of causes have been proposed.

GNSS Observations of the Land Uplift in South Africa: Implications for Water Mass Loss

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Continuously operating Global Navigation Satellite System (GNSS) base stations in South Africa show a spatially coherent vertical displacement. While one hypothesis attributes this vertical motion to crustal deformation from mantle flow and dynamic topography (Hammond et al., 2021, https://doi.org/10.1029/2021jb022355), we propose an ...

Paleomagnetic Secular Variation of Early Middle Miocene Volcanics From Vogelsberg (Germany)

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract The Earth's magnetic field significantly changed its rate of polarity reversals over the past 200 Myr; yet it remains controversial whether these drastic changes—from a stable state of polarity during the Cretaceous Normal Superchron to more than 10 events per Myr during the Jurassic—are accompanied with similar changes in the directional ...

The Role of Long‐Term Hydrodynamic Evolution in the Accumulation and Preservation of Organic Carbon‐Rich Shelf Sea Deposits

Journal of Geophysical Research: Oceans, Volume 130, Issue 4, April 2025.
Abstract Understanding and mapping seabed sediment distribution in shelf seas is essential for effective coastal management, offshore developments, and for blue carbon stock assessments and conservation. Fine‐grained marine sediments, particularly muds, play a key role in long‐term organic carbon sequestration, so knowledge of the spatial extent of ...

Impacts Into Titan's Methane‐Clathrate Crust as a Source of Atmospheric Methane

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Titan is the only icy satellite in the solar system with a dense atmosphere. This atmosphere is composed primarily of nitrogen with a few percent methane, which supports an active, methane‐based hydrological cycle on Titan. The presence of methane, however, is intriguing, as its lifetime is likely much shorter than the age of the solar system ...
