Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
Other labels refer to the ice tongue's grounding line, and northern and southern shear zones where it's in direct contact with the ice shelf. [ 29 ] The Thwaites Glacier Tongue, or Western Glacier Tongue ( 75°0′S 106°50′W / 75.000°S 106.833°W / -75.000; -106.833 ) was a narrow, floating part of the glacier, located about 30 ...
This re-freezing and growth of an ice shelf is not uncommon but the Ross Ice Shelf situation appeared to be very variable as there was no evidence of long-term freezing. [20] A recent study attribute this variability in-part to tidal mixing. [21] A second New Zealand expedition in 2019 traveled to the grounding line region of the Kamb Ice Stream.

These aggregates are usually the type of ice particle that falls to the ground. [ 8 ] Guinness World Records lists the world's largest aggregated snowflakes as those of January 1887 at Fort Keogh , Montana , which were claimed to be 15 inches (38 cm) wide—well outside the normally documented range of aggregated flakes of three or four inches ...
The effect subglacial stream discharge has on glacial melt is also influenced by the type of subglacial drainage system; distributed subglacial streams result in an output of meltwater uniformly across the grounding line (where the glacier transitions from grounded to floating ice), whereas channelized drainage results in individual, large ...
