A clay model of the Mid-Atlantic Ridge between 12° and 15°N, based on a survey with 8-km line spacing, reveals the irregular character of the medium-scale ridge topography. The median valley is far from constant in cross-section, ranging from an asymmetric V-shaped valley to shallower ...
A clay model of the Mid-Atlantic Ridge between 12° and 15°N, based on a survey with 8-km line spacing, reveals the irregular character of the medium-scale ridge topography. The median valley is far from constant in cross-section, ranging from an asymmetric V-shaped valley to shallower ...
Detailed maps of bathymetry, free air gravity anomaly, and total field magnetic anomaly are presented for an area approximately 50×20mi along the crest of the ridge. The median valley and the associated belt of large positive magnetic anomalies are continuous and display a striking lineation in ...
A method is developed to quantify the relationship between the ridge axial topography and gravity and the spreading rate along the MidAtlantic Ridge between 22 and 38掳N. This relationship reflects the variations of slope of the bestfit line of topography and gravity spectra with the spreading ...
A composite map showing the topography (relief) of the ocean floor clearly reveals the mid-ocean ridge system, which appears here as dark "seams" extending through the oceans. In the Atlantic Ocean, the mid-ocean ridge is called the Mid-Atlantic Ridge. It curves from the Arctic Ocean southw...
1. What is the most famous Mid-Ocean Ridge? The Mid-Atlantic Ridge, located in the Atlantic Ocean, is the most famous Mid-Ocean Ridge, spreading at a rate of 0.8 to 2 inches yearly. 2. What are Mid-Ocean Ridges? Mid-Ocean Ridges are long, seismically active underwater ridge formations...
A global analysis of mid-ocean ridge axial topography Current views of mid-ocean ridges are strongly influenced by extensive mapping of the Mid-Atlantic Ridge and East Pacific Rise. The global picture of the m... C Small - 《Geophysical Journal of the Royal Astronomical Society》 被引量: 32...
Here, we use near-seafloor magnetic and bathymetric data and seismic profiles collected over the TAG Segment of the Mid-Atlantic Ridge to constrain the tectonic evolution of these blocks. Our study reveals that the presence and evolution of oceanic core complexes play a key role in triggering ...
A survey of the Mid-Atlantic Ridge crest in the region of the Kurchatov Fracture Zone (40.5°N) employing a long-range side-scan sonar is described. Away from the fracture zone, long straight faults spaced about 2 km apart and parallel to the ridge axis were seen. Almost all of these ...
older crust is pushed away from the ridge axis, causing the ocean floor to expand. The rate of spreading varies across different ridges:fast-spreading ridgeslike the East Pacific Rise have smoother topography, whileslow-spreading ridgeslike the Mid-Atlantic Ridge feature rugged terrain with steep ...
