A three-dimensional study of a crustal low velocity region beneath the 9°03′N overlapping spreading center

, 2003
Overlapping spreading centers (OSCs) play a key role in models of magma distribution at fast spreading ridges. To investigate the relationship between ridge-axis discontinuities and magma supply, we conducted a three-dimensional seismic reflection and ...

Post Eruption inflation of the East Pacific Rise at 9°50′ N

Geochemistry, Geophysics, Geosystems, 2014
In June 2008, we installed a geodetic network at 9°50′ N on the East Pacific Rise to track the long‐term movement of magma following the 2005/6 eruption. This network consists of 10 concrete benchmarks stretching from the ridge to 9 km off‐axis.

Turbulence Observations in a Buoyant Hydrothermal Plume on the East Pacific Rise [PDF]

Oceanography, 2012
Hot vent fluid enters the ocean at high-temperature hydrothermal vents, also known as black smokers. Because of the large temperature difference between the vent fluid and oceanic near-bottom waters, the hydrothermal effluent initially rises as a buoyant

High‐Resolution Isotopic Variability Across EPR Segment 16°N: A Chronological Interpretation of Source Composition and Ridge‐Seamount Interaction

Geochemistry, Geophysics, Geosystems, 2021
A high‐resolution sampling profile constituted of 52 basalt samples from across the East Pacific Rise (EPR) was investigated. These samples provide a unique opportunity to study the coeval recording of isotopic signals derived from sub‐marine eruptions ...

The TsuJal Amphibious Seismic Network: A Passive-Source Seismic Experiment in Western Mexico

Frontiers in Earth Science, 2021
The geodynamic complexity in the western Mexican margin is controlled by the multiple interactions between the Rivera, Pacific, Cocos, and North American plates, as evidenced by a high seismicity rate, most of whose hypocenters are poorly located.

Active eruption seen on East Pacific Rise

Eos, Transactions American Geophysical Union, 1991
Investigators involved in the ADVENTURE program, an Alvin dive program on the East Pacific Rise crest at 9°–10°N, have reported evidence suggesting very recent and possibly ongoing eruptive activity along this portion of the mid‐ocean ridge. Preliminary age dating of basalt samples from the new flows (Figure 1) suggest that the eruption did, in fact ...

“Plate‐like” subsidence of the East Pacific Rise–South Pacific superswell system [PDF]

Journal of Geophysical Research: Solid Earth, 2004
In previous studies the removal of small‐scale features such as seamounts and oceanic islands from bathymetry has revealed a large and unusually shallow region in the South Pacific Ocean, which, at 3000 km wide and up to 1 km high, has been dubbed a “superswell.” These studies use statistical techniques based on finding the modal depth of the ...
