The database and map represent a substantial upgrade from the previous compilation of magnetic anomaly data for North America, now over a decade old. This integrated, readily accessible, modern digital database of magnetic anomaly data will be a powerful tool for further evaluation of the ...
A free-air gravity map of the Guiana Basin between 15掳 N. and 6掳 S. in the western equatorial Atlantic, using all available shipboard and pendulum data, is presented. The gravity field is interpreted in terms of short wave-length compo... JR Cochran - 《Geological Society of America Bu...
The newly updated North American magnetic anomaly map is a culmination of the compilation of these analog-converted (digitized) and digital magnetic data for the United States. The need to create individual U.S. state compilations generated a project designed to recover archived magnetic data from ...
NASA has been monitoring a strange 'growing' anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest AfricaScience Alert - December 29, 2024 ...
that it has returned to an area of origin after a long migration, or that it is approximately north or south of a place where it lives. Thus, in the lexicon of the animal navigation literature, an animal has a magnetic map if it derives positional information from Earth’s magnetic field...
The first composite magnetic-anomaly map of the conterminous United States and adjacent offshore areas has been published at a color-contour interval of 200 gammas and at the scale and projection of other national geologic and geophysica... WJ Hinze,I Zietz - The Utility of Regional Gravity an...
The Earth Magnetic Anomaly Grid (EMAG) is compiled from data collected by magnetometers on satellites, ships, and even those aboard or towed behind aircraft, like an airplane or helicopter. EMAG maps the strength of static magnetic anomalies. A magnetic anomaly is an inconsistency in Earth's ma...
Chris Finlay, senior scientist at DTU Space in Denmark, said, “Swarm data are now enabling us to map detailed changes in Earth's magnetic field, not just at Earth's surface but also down at the edge of its source region in the core. “Unexpectedly, we are finding rapid localised fiel...
<p id="abspara0010" view="all"> We have estimated the DBML (depth to the bottom of the magnetic layer) in South America from the inversion of magnetic anomaly data extracted from the EMAG2 grid. The results show that the DBML values, interpreted as the C
Other major compilation is the EMAG3 - NGDC's candidate for the World Digital Magnetic Anomaly Map. Its major limitation is that magnetic data are upward continued to an altitude of 5 km, which greatly reduces its usefulness for purposes of isochrones identification and kinematics studies. In a...
