dynamics and meteorite collection in Antarctica Earth

Pages 371-378, (30 October 2003)

In part, the abstract stated:

"Typical targets for meteorite searches in Antarctica
are blue ice fields in front of major bedrock obstacles,
where the meteorite-bearing ice slows down, is
uplifted and exhumed by ablation. However, in some
areas collection occurs in the lee of topographic
barriers, as documented in the downstream side of the
Frontier Mountain, a major emerged bedrock barrier."

and

"Results of modelling show how the boundary conditions
(mainly the bedrock topography) control ice flow and
how this flow, coupled to high ablation, may give rise
to a stable meteorite trap downstream of major
topographic obstacles."
