We present a new synthesis of oceanic crustal structure from two‐dimensional seismic
profiles to explore differences related to spreading rate and age. Primary results are as …

Hot spot–mid‐ocean ridge interactions cause many of the largest structural and chemical
anomalies in Earth's ocean basins. Correlated geophysical and geochemical anomalies are …

Among the various university courses I took for my geoscience degree, volcanology and
structural geology motivated me by far the most. Volcanoes and deformed rocks are indeed …

The global ridge system is dominated by oceanic rises reflecting large variations in axial
depth associated with mantle hotspots. The little-studied Marion Rise is as large as the …

Convective circulation of the mantle causes deflections of the Earth's surface that vary as a
function of space and time. Accurate measurements of this dynamic topography are …

The Cocos plate experiences extensional faulting as it bends into the Middle American
Trench (MAT) west of Nicaragua, which may lead to hydration of the subducting mantle. To …

Multiple‐and single‐beam bathymetric data are compiled over the Azores plateau to
produce a 1 km× 1 km grid between latitudes 32° N and 49° N and longitudes 22° W and …

Mid-ocean ridges display tectonic segmentation defined by discontinuities of the axial zone,
and geophysical and geochemical observations suggest segmentation of the underlying …

The Caribbean plate is an enclosed oceanic basin whose formation and evolution are
controversial. In the most commonly accepted model, the Caribbean plate is mainly …

The Cocos and Malpelo Volcanic Ridges are blocks of thickened oceanic crust thought to be
the result of the interaction between the Galapagos hot spot and the Cocos‐Nazca …
