A noticeable trait of iceberg ice is the presence of several sets of planar features cross-cutting each other at various angles. Close-up views of these features show that they consist of an array of individual air inclusions that differ in size, shape and spatial distribution. In none of the cases resolvable at the scale of our obervations were these inclusions physically linked to form a continuous fracture plane, although they may have originated as such. All postdate the formation of ice veins. NRC publication: Yes
