Sentences with phrase «significant thickness of these ice»

Not exact matches

As significant uncertainties about the thickness of the surface ice still exist, some planetary scientists have identified two possible mechanisms for how possible volcanic heat can escape to the surface from Europa's rocky mantle and be carried upward by buoyant oceanic currents.

To establish this uncertainty in the ice - volume record (Schweiger et al. 2011), we spent a significant effort drawing on most types of available observations of ice thickness thanks to a convenient compilation of ice thickness data (Lindsay, 2010).

Still more striking, and significant, has been a severe decline in the average thickness of the ice pack, and thus of its volume (graph).

A loss of 4.2 meters of ice thickness on glaciers with an estimated mean thickness of 30 - 50 meters (Post et al., 1971) is significant.

Well they are predicting 2C tonight in Central South America (Tropics - subtropics) as I have said many times on this site, I believe that the highly significant constant increase in antarctica ice extent and thickness may begin to affect the reach of polar air into the southern latitudes if it happens to be directed in the right direction making it go farther north than usual.

Examination of records of fast ice thickness (1936 — 2000) and ice extent (1900 — 2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long - term ice thickness and extent trends are small and generally not statistically significant, while trends for shorter records are not indicative of the long - term tendencies due to large - amplitude low - frequency variability.

This is on top of very significant drops in average ice thickness.

The model simulation does not contain assimilated ice thickness data and shows significant differences in particular in the region north of Greenland.
