Imaging complex structures with semi-recursive Kirchoff migration
Attempting to image the subsurface in areas of complex geology and rapid lateral velocity variation is a challenging problem. In particular, using prestack Kirchhoff migration in conjunction with first arrival travel times ...
Analysis of the application of collision cross sections and ion neutral reaction rates in the upper atmosphere modeling
Review and analysis of atomic collision data (such as collision cross sections and ion-neutral reaction rates) used in the upper atmospheric modeling for Earth and other planets are presented. This work gives the first ...
The motion between Nubia and Somalia from magnetic anomaly and fracture zone crossings flanking the Southwest Indian Ridge
Previous reconstructions for anomaly 5 and older anomalies flanking the Southwest Indian Ridge (SWIR) have indicated no statistically significant evidence for motion between the Nubian and Somalian plates. Recently, an ...
