The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins
Terra Nova, EarlyView.ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Emergence of Continents Stabilized the Bioavailability of Boron
Terra Nova, EarlyView.ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

LANDSAT survey of near-shore ice conditions along the Arctic coast of Alaska [PDF]
The author has identified the following significant results. Winter and spring near-shore ice conditions were analyzed for the Beaufort Sea 1973-77, and the Chukchi Sea 1973-76.

Teleseismic Indication of Magmatic and Tectonic Activities at Slow- and Ultraslow-Spreading Ridges
Journal of Marine Science and EngineeringMagmatic and tectonic processes in the formation of oceanic lithosphere at slow–ultraslow-spreading mid-ocean ridges (MORs) are more complicated relative to faster-spreading ridges, as their melt flux is overall low, with highly spatial and temporal ...

Global isostatic geoid anomalies for plate and boundary layer models of the lithosphere [PDF]
Commonly used one dimensional geoid models predict that the isostatic geoid anomaly over old ocean basins for the boundary layer thermal model of the lithosphere is a factor of two greater than that for the plate model.

This activity was designed to help students develop a better understanding of the Earth's plates and their distribution. They will explore plate motions and the interactions of the plates along the plate boundaries by re-assembling a map of the earth ...

General theory of the modified Gutenberg-Richter law for large seismic moments
, 1999 The Gutenberg-Richter power law distribution of earthquake sizes is one of the most famous example illustrating self-similarity. It is well-known that the Gutenberg-Richter distribution has to be modified for large seismic moments, due to energy ...

Studies of the inner shelf and coastal sedimentation environment of the Beaufort Sea from ERTS-A [PDF]
The author has identified the following significant results. Shearing periodically occurs between the westward moving pack ice (3 to 10 km/d) within the Pacific Gyre and the fast ice along the coast, forming major grounded shear and pressure ridges ...
