in which u is the total pore pressure; it can be expressed by pore water pressure [u.sub.w] and pore ice
Surface features common in the northern and southern mid latitudes of Mars and known as lobate debris aprons and lineated valley fill are believed to have formed either as debris flows mobilized by pore ice
or as debris-covered glaciers.
The perceived stability of the sea bottoms and the low ice content (pore ice
) of the overland route across Nunavut suggests that an ambient-temperature pipeline might be possible, at least for part of the route.
