Structure of the southern Jalisco subduction zone, Mexico, as inferred from gravity and seismicity [PDF]

open access: yesGeofísica Internacional, 1999
A type-model of the geological structure of the Jalisco subduction zone was determined by matching gravity anomalies observed along a profile perpendicular to the Jalisco coast near Barra de Navidad with the gravitational attraction of a geologic cross

Determining gene flow and the influence of selection across the equatorial barrier of the East Pacific Rise in the tube-dwelling polychaete Alvinella pompejana

open access: yesBMC Evolutionary Biology, 2010
Background Comparative phylogeography recently performed on the mitochondrial cytochrome oxidase I (mtCOI) gene from seven deep-sea vent species suggested that the East Pacific Rise fauna has undergone a vicariant event with the emergence of a north ...

Asymmetric seafloor depth across the Juan de Fuca Ridge caused by lithospheric heating

open access: yesCommunications Earth & Environment, 2023
Previous studies attribute asymmetries across the East Pacific Rise to horizontal temperature or pressure gradients in the deep asthenosphere caused by the Pacific Superswell, which, however, cannot explain asymmetries observed across the Juan de Fuca ...

Variations in the annual cycle of the East Asian monsoon and its phase-induced interseasonal rainfall anomalies in China

open access: yesAtmospheric and Oceanic Science Letters, 2020
The East Asian monsoon (EAM) exhibits a robust annual cycle with significant interannual variability. Here, the authors find that the EAM annual cycle can be decomposed into the equinoctial and solstitial modes in the combined sea level pressure, 850-hPa

262 Voyages Beneath the Sea: a global assessment of macro- and megafaunal biodiversity and research effort at deep-sea hydrothermal vents [PDF]

open access: yesPeerJ, 2019
For over 40 years, hydrothermal vents and the communities that thrive on them have been a source of profound discovery for deep-sea ecologists. These ecosystems are found throughout the world on active plate margins as well as other geologically active ...

Geological and geophysical signatures of the East Pacific Rise 8°–10°N

open access: yesSolid Earth Sciences, 2019
The East Pacific Rise (EPR) 8°–10°N is an archetype for fast-spreading mid-ocean ridge (MOR), and has been one of the most comprehensively studied MOR sections for over four decades.

Atmospheric torques and Earth's rotation: what drove the millisecond-level length-of-day response to the 2015–2016 El Niño? [PDF]

open access: yesEarth System Dynamics, 2017
El Niño–Southern Oscillation (ENSO) events are classically associated with a significant increase in the length of day (LOD), with positive mountain torques arising from an east–west pressure dipole in the Pacific driving a rise of atmospheric angular

Gravity Anomalies and Implications for Shallow Mantle Processes of the Western Cocos‐Nazca Spreading Center

open access: yesGeophysical Research Letters, 2023
This study analyzes up‐to‐date gravity data in the Galapagos triple junction region to understand crustal structure and melt distribution beneath the propagating Cocos‐Nazca spreading center (CNSC).

The Rebalance to Asia Policy of the Obama Administration (2011–2017): Diversifying the United States Security Design in Asia-Pacific

open access: yesPerspective Politice, 2022
The gradual and steady growth of China’s economic and military power over the past decades has reoriented the foreign policy priority of the United States from the Middle East to the East Asian region. In 2011, U.S.
