TL;DR: In this article, a global Earth Magnetic Anomaly Grid (EMAG2) has been compiled from satellite, ship, and airborne magnetic measurements, both over land and the oceans, where the original shipborne and airborne data were used instead of precompiled oceanic magnetic grids.

TL;DR: In this article, the authors use aerogeophysical measurements to constrain the geological setting of the onset of an active West Antarctic ice stream, which coincides with a sediment-filled basin incised by a steep-sided valley.

TL;DR: In this article, the authors present aerogeophysical evidence for active volcanism and associated elevated heat flow beneath the West Antarctic ice sheet near the critical region where ice streaming begins, and if this heat flow is indeed controlling ice-stream formation, then penetration of ocean waters inland of the thin hot crust of the active portion of the West Antarctica rift system could lead to the disappearance of ice streams, and possibly trigger a collapse of the inland ice reservoir.

TL;DR: The evolution of the Gamburtsevs demonstrates that rifting and preserved orogenic roots can produce broad regions of high topography in continental interiors without significantly modifying the underlying Precambrian lithosphere.

TL;DR: In this paper, the authors suggest that sudden detachment and sinking of subducted slabs in the late Cretaceous induced Rayleigh-Taylor instabilities along the former Gondwana margin that in turn triggered lateral and vertical flow of warm Pacific mantle.
