The landscape is a flat ice desert and, had we not had a GPS, we would have had no idea in which direction to ski.
After struggling to make headway over several days, the march was abandoned; the party established "Patience Camp" on a flat ice floe, and waited as the drift carried them further north, towards open water.
Of greater immediate interest, Dr. Thompson and his team have expanded on previous research involving long-dead plants emerging from the melting ice at the edge of Quelccaya, a huge, flat ice cap sitting on a volcanic plain 18,000 feet above sea level.
The reason that hAFP did not evolve a large flat ice-binding site with perfect ice lattice match may be due to the involvement of the Ca2+ cofactor, which provides sufficient binding force through coordination of water in the ice lattice.
(B ) Side view of equilibrated simulation at 230 K showing a relatively flat ice front.
Ca2+-independent type II AFPs have most likely evolved by developing a potentially larger flat ice-binding surface similar to that of other types of AFPs, that ensured strong interactions with the ice lattice even in the absence of the Ca2+ ion.
The terrain in that direction was mostly extremely difficult, sometimes necessitating a crawl on all fours, but there was occasional relief in the form of open water the little boat (not designed by Andrée) was apparently a functional and safe conveyance and smooth, flat ice floes.
A fire starting lens can be made from clear and flat ice by melting one side of a piece of it in the palm of your hand so that the melted side becomes rounded like a lens.
The cube, really more of a hexagon, consists of just six molecules of water in a flat ring, which is the way ice occurs in nature.
Some parts of the test area are flat ice sheets studded with occasional, distinct rocks while others are moraines, dense concentrations of rock and rubble deposited by glaciers.
