Sentences with phrase «increased ice velocities»

Not exact matches

The current flow speeds at the terminus are too fast to be caused solely by internal deformation of the ice, implying that an increase in basal sliding forced by additional meltwater production is the probable cause of the velocity increases.
The higher ice velocities in the base case CHW simulations are attributable to both decreased basal ice viscosities associated with increased basal ice temperatures and an increase in the extent of basal sliding permitted by temperate bed conditions.
The two papers don't mention any velocity changes due to increased slope, but they do record that at elevations above 1500 - 2000 m, the ice has been growing in thickness by about 5 - 6 cm / yr, whereas below the 1500m level there's been a thinning of about -2 cm / yr.
During retreat phase, a tidewater glacier may retreat on the order of 1 - 2 km yr - 1 concurrent with dramatic increases in ice velocity...»
So, the positive feedback between melt and velocities implies that more melt leads to higher velocities, which bring in more ice from cold regions to warm regions which increases the melt and hence the velocity etc, with as a final result a rapid loss of ice and hence an enhanced increased sea level.
Rather it claims that decreased ozone increases the velocity of the circumpolar vortex, thus breaking up pack ice and allowing more ice to form at the surface, thereby contributing to greater sea ice extent.
With greater accumulation of dense ice on the crystal, its fall velocity increases.
At all points of the compass, the entire outer edge of the Greenland Ice Sheet is flooding into the oceans with increasing velocity.
Based on the velocity map, it is the Zachariae that is likely the only of this group that would be comparable to a bank that is too big to fail as its increased velocity band extends well into the ice sheet.
