Gravity, magnetic, and bathymetry data collected along a continuous 1,400‐km‐long spreading‐parallel flow line across the Mid‐Atlantic Ridge indicate significant tectonic and magmatic fluctuations in the formation of oceanic crust over a range of time scales. The transect spans from 28 Ma on the African Plate to 74 Ma on the North American plate, crossing the Mid‐Atlantic Ridge at 35.8°N. Gravity‐derived crustal thicknesses vary from 3–9 km with a standard deviation of 1.0 km. Spectral analysis… 

Time‐Dependent Crustal Accretion on the Southeast Indian Ridge Revealed by Malaysia Airlines Flight MH370 Search

Our understanding of oceanic crustal formation is mostly limited to observations of young crust formed in the past several million years, due to the thick sediments on older crust and the remote

Persistent Magma‐Rich Waves Beneath Mid‐Ocean Ridges Explain Long Periodicity on Ocean Floor Fabric

The ocean floor makes up the majority of the Earth's surface and yet, its geomorphology is not fully understood. Recent debate has focused on whether sea level changes—driven by Milankovitch glacial

The existence, or not, of periodicities in abyssal hill morphology has been vigorously debated in recent publications, and some have hypothesized that such periodicities are evidence of the impact of



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

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

Heterogeneous and asymmetric crustal accretion: New constraints from multibeam bathymetry and potential field data from the Rainbow area of the Mid‐Atlantic Ridge (36°15'N)

At slow‐spreading mid‐ocean ridges, crustal accretion style can vary significantly along and across ridge segments. In magma‐poor regions, seafloor spreading can be accommodated largely by tectonic

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

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

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.

Oceanic core complex development at the ultraslow spreading Mid‐Cayman Spreading Center

Roughly a third of the global mid‐ocean ridge system spreads at <20 mm/yr (full rate) with predicted low crustal thicknesses, great axial depths, end‐member basalt compositions, and prominent axial

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

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

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
