Understanding Sub‐Lithospheric Small‐Scale Convection by Linking Models of Grain Size Evolution, Mantle Convection, and Seismic Tomography

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract The interaction between aging oceanic plates and their underlying mantle is a crucial component of the plate tectonic cycle. Sub‐lithospheric small‐scale convection (SSC) explains why plates appear not to thicken after a certain age. Here, we link grain‐scale processes, dynamic models of asthenospheric flow, and seismic observations to gain ...

Moho Depth Disposition of the Contiguous United States: A Multi‐Modal Data Driven Approach

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Precise determination of Moho depth is essential for understanding lithospheric deformation, lower crustal rheology, and crust‐mantle interactions. This study employs a Random Forest Regressor (RFR) model to predict Moho depth across the contiguous United States using a variety of geophysical data, including gravity anomalies, topography, heat

REHEATFUNQ (REgional HEAT-Flow Uncertainty and aNomaly Quantification) 2.0.1: a model for regional aggregate heat flow distributions and anomaly quantification [PDF]

Geoscientific Model Development
Surface heat flow is a geophysical variable that is affected by a complex combination of various heat generation and transport processes. The processes act on different lengths scales, from tens of meters to hundreds of kilometers.

Revised Oceanic Plate Cooling Models

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Global age‐depth and heat flow observations provide constraints for cooling and subsidence of oceanic plates. Numerous studies have addressed this problem, which has a bearing upon the calibration of shear‐wave tomographic models and upon lithospheric rheology.

Magma‐Assisted Flexure of Hawaiian Lithosphere Inferred From Three‐Dimensional Models of Lithospheric Flexure Constrained by Active Source Seismic Data

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Reprocessed and newly acquired seismic data provide new constraints on lithospheric flexure profiles beneath the Hawaiian Islands. We use these new observations and three‐dimensional numerical models of lithospheric deformation combining elasticity, brittle failure, low‐temperature plasticity (LTP) and high‐temperature creep deformation ...

Behavioral modeling of integrated phase-change photonic devices for neuromorphic computing applications [PDF]

, 2019
The combination of phase-change materials and integrated photonics has led to the development of new forms of all-optical devices, including photonic memories, arithmetic and logic processors, and synaptic and neuronal mimics. Such devices can be readily

Deep and Clustered Microseismicity at the Edge of Southern New Zealand's Transpressive Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract Deep (>∼ ${ >} \sim $20 km) crustal seismicity is typically associated with cold Precambrian lithosphere. However, previous studies have reported that the depth above which 90% of seismicity occurs (D90) in the Southland region of New Zealand is 30–35 km, even though it is situated in relatively young Mesozoic crust at the eastern edge of the ...

Crustal Heterogeneity Onshore Central Spitsbergen: Insights From New Gravity and Vintage Geophysical Data

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 1, January 2025.
Abstract Gravity data provide constraints on lateral subsurface density variations and thus provide crucial insights into the geological evolution of the region. Previously, gravity data from the Norwegian Arctic archipelago of Svalbard comprised an onshore regional gravity database with coarse station spacing of 2–20 km, offshore gravity profiles ...
