(b) ALTAIR map showing the launching of the primary EPB from the crest of the upwelling.
A tilted echoing region is more or less aligned with the west wall of the upwelling.
Once an upwelling grows in amplitude, primary EPBs would be launched from the crest of the upwelling followed by the development of secondary EPBs along the west wall of the upwelling.
The EPBs eventually encroach into the region that was occupied originally by the east wall of the upwelling.
The continent of Africa has moved and rotated just slightly over the intervening millions of years, shifting the relative location of the upwelling.
The upwelling magma caused the region to dome and rise.
Forget the cosmic solitude, the upwelling awe and dread".
Ten years ago, the upwelling of solidarity, from coast to coast, was a profound consolation.
Sea fog is frequent along the coasts, especially in the upwelling cold-water areas.
The changes in oceanic circulation resulted in the upwelling of deep waters off the western coast of North America.
New lithosphere is created at oceanic ridges by the upwelling and cooling of magma from the Earth's mantle.
