Glaciers confined within a path that directs their movements are mountain glaciers, those that spread on level ground at the foot of a glaciated region are piedmont glaciers, and those that spread from a glaciated region onto the ocean are ice shelves. Ice floes, on the other hand, are made of frozen seawater.
As a team, you need to identify an ice floe that is suitable to park/attach your icebreaker in. You will be using data and the ice floe guidelines from MOSAiC to do this.
An iceberg is a large mass of freshwater ice that has broken off of a glacier or an ice shelf. An ice floe is a large, flat pack of floating ice. The difference between the two is that most of the ice floe’s mass is above the water’s surface, while about 90% of an iceberg’s mass is underwater.
Floe ice . Extensive area of sea covered with floes of various sizes; differs from a field in that, from the masthead, open water patches can be seen here and there (47).
The most productive sea-ice factories in the Southern Ocean are the polynyas off the Ross Ice Shelf (producing 253 cubic kilometres of sea ice per year), the Cape Darnley polynya in the East Antarctic (127 cubic kilometres), and the polynya offshore of the Mertz Glacier (125 cubic kilometres).
A glacier is different from an ice floe or pack ice. Glaciers are formed on land (on continents), while ice floes and pack ice float on water (in oceans). There are two main types of glacier: ice caps and glaciers dependent on relief.
19 sty 2018 · Find out what makes ice floes, ice jams and ice shoves different. During winter, water in a river can rise, form into ice and then disintegrate into ice floes, shoves or jams. But what's the ...
