1. We conducted one of the longest continuous geophysical surveys along a 74-Myr 15 spreading-parallel flow line across the Mid-Atlantic Ridge. 16 2. Spectral densities of bathymetry and gravity data show concurrent peaks at 390-, 550-, 17 and 950-kyr periods, and diffuse power at >1 Myr. 18 3. A negative correlation between fault spacing and gravity-derived crustal thickness 19 suggests a link between magma input and fault style. 20 21 Abstract: 22 Gravity, magnetic, and bathymetry data… 
Oceanic crustal structures and temporal variations of magmatic budget during seafloor spreading in the East Sub-basin of the South China Sea
Abstract Following magma-poor continental rifting, the South China Sea (SCS) experienced seafloor spreading from ~33 Ma to ~15 Ma with an intervening southward ridge jump at ~25 Ma, generating the

Gravity anomalies and crustal thickness variations along the Mid‐Atlantic Ridge between 33°N and 40°N
Multibeam bathymetry and gravity data have been obtained along an ∼800-km-long section of the Mid-Atlantic Ridge from just south of the Hayes fracture zone at 33°N to the northern edge of the Azores
Temporal and spatial variations in crustal accretion along the Mid‐Atlantic Ridge (29°–31°30′N) over the last 10 m.y.: Implications from a three‐dimensional gravity study
We have conducted a three-dimensional gravity study of the Mid-Atlantic Ridge near the Atlantis Transform to study the evolution of accretionary processes at this slow-spreading center over the last
Seismic structure across the rift valley of the Mid‐Atlantic Ridge at 23°20′ (MARK area): Implications for crustal accretion processes at slow spreading ridges
The results from a 53-km-long, wide-angle seismic profile across the rift valley of the Mid-Atlantic Ridge south of the Kane transform (near 23°20′N, MARK area) provide new constraints on models of
Magnetization of 0–29 Ma ocean crust on the Mid-Atlantic Ridge, 25°30′ to 27°10′N
A sea-surface magnetic survey over the west flank of the Mid-Atlantic Ridge from 0 to 29 Ma crust encompasses several spreading segments and documents the evolution of crustal magnetization in slowly
Mantle thermal pulses below the Mid-Atlantic Ridge and temporal variations in the formation of oceanic lithosphere
Slow-spreading lithosphere seems to form through dynamic pulses of mantle upwelling and melting, leading not only to along-axis segmentation but also to across-axis structural variability.
Gravity anomalies of the ridge-transform system in the South Atlantic between 31 and 34.5° S: Upwelling centers and variations in crustal thickness
To decipher the distribution of mass anomalies near the earth's surface and their relation to the major tectonic elements of a spreading plate boundary, we have analyzed shipboard gravity data in the
Crustal and upper mantle seismic structure beneath the rift mountains and across a nontransform offset at the Mid-Atlantic Ridge (35°N)
We present new results on the crustal and upper mantle structure beneath the rift mountains along two segments of the Mid-Atlantic Ridge and across a nontransform offset (NTO). Our results were
Crustal structure of the Southwest Indian Ridge at 66°E: seismic constraints
The Southwest Indian Ridge represents a slow-spreading end-member of the global mid-ocean ridge system, and as such its structure places important constraints on models of melt supply and delivery
Variable crustal structure along the Juan de Fuca Ridge: Influence of on‐axis hot spots and absolute plate motions
Multichannel seismic and bathymetric data from the Juan de Fuca Ridge (JDFR) provide constraints on axial and ridge flank structure for the past 4–8 Ma within three spreading corridors crossing
Segmentation and crustal structure of the western Mid-Atlantic Ridge flank, 25°25′–27°10′N and 0–29 m.y.
We conducted a detailed geological-geophysical survey of the west flank of the Mid-Atlantic Ridge between 25°25′N and 27°10′N and from the ridge axis out to 29 Ma crust, acquiring Hydrosweep
