Abstract Three-dimensional (3D) seismic and outcrop data are used to review the
significance of submarine slide blocks and associated soft-sediment deformation structures …

The first attempts to quantify the width and height of hotspot swells were made more than 30
years ago. Since that time, topography, ocean-floor age, and sediment thickness datasets …

Since flat subduction of the Nazca Plate beneath Peru was first recognized in the 1970s and
1980s a satisfactory explanation has eluded researchers. We present evidence that a lost …

The morphology and structure of the submarine flanks of the Canary Islands were mapped
using the GLORIA long‐range side‐scan sonar system, bathymetric multibeam systems, and …

Results from a recent marine geophysical survey demonstrate the importance of the process
of flank collapse in the growth and evolution of volcanoes along an island arc. The …

Surface ocean iron (Fe) fertilization can affect the marine primary productivity (MPP), thereby
impacting on CO2 exchanges at the atmosphere‐ocean interface and eventually on climate …

Geophysicists have long sought direct, incontrovertible evidence from surface observables
for convection in Earth's mantle. One of the best candidates for a phenomenon of convective …

This review focuses on the recognition of volcanic ash occurrences in marine sediment
cores and on using their appearance and properties to deduce their origin. Widespread …

VOLCANISM in active continental rift zones1, 2or on rifted continental margins3is frequently
associated with unusually high lower-crustal seismic velocities, indicating the presence of …

Topographic rises on Venus have been identified that are interpreted to be the surface
manifestation of mantle upwellings. These features are classified into groups based on their …
