Seismicity of ultraslow-spreading mid-ocean ridges

, 2013
In this thesis, I synthesize my research on the seismicity of ultraslow spreading ridges describing the overarching theme of 10 peer-reviewed publications. At mid-ocean ridges, the lithospheric plates drift apart, magma fills the gap to form new crust.

The Effects of a Microplate on Plume‐Ridge Interactions: Constraints From Comparing Easter and Juan Fernandez Microplates in the Eastern Pacific Ocean

Geochemistry, Geophysics, Geosystems
This study investigates the nature of plume‐ridge interactions near a tectonic microplate using mantle Bouguer anomaly (MBA) gravity calculations. The focus of this investigation is a comparison of the Easter and Juan Fernandez microplates, which are ...

Rifting processes at ultraslow mid-ocean ridges

, 2014
Mid-ocean rift systems opening at full spreading rates < 20 mm/y differ in their structure from all faster spreading ridges. One of the key differences is that the small amount of available melt is not distributed evenly along the ridge axis.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, Volume 309, Issue 11, Page 3091-3105, November 2026.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Magnetic Imaging of the Effect of Stress on the Remanent Magnetization of Basalt

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Differential compressional stresses (<100 MPa) that do not result in permanent deformation have traditionally been considered insufficient to modify paleomagnetic signals; however, recent numerical predictions have challenged this assumption.

Different Orbital Controls on Detrital Magnetic Components in the Ninety‐East Ridge Since the Late Pleistocene

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Magnetic minerals preserved in marginal‐sea sediments can serve as distinct fingerprints for unraveling paleoenvironmental evolution. However, the forcing mechanisms that govern the transport and accumulation of individual magnetic minerals at orbital timescales remain poorly constrained.

Interdecadal Phase Shifts of Winter Asian‐Pacific Oscillation Modulate the Warm Arctic‐Cold Eurasia Pattern

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Against the backdrop of global warming, warm Arctic‐cold Eurasia (WACE) has garnered extensive scientific attention. However, the drivers of its interdecadal variability remain insufficiently understood. Using reanalysis data and pre‐industrial control simulations, we demonstrate that winter Asian‐Pacific Oscillation (APO), a dominant upper ...

Role of Unbalanced Jet Streak Circulations in East Asian Dust Storms

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract A mesoscale study of three severe dust storms over China and Mongolia was conducted using observational and high‐ resolution numerical model data sets. The analysis of these data indicates many commonalities among the three case studies, (a) precursor wind flow across the mountain creating a strong statically stable layer in the lee of the ...
