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.
An ice floe (/ f l oʊ /) is a large pack of floating ice often defined as a flat piece at least 20 m across at its widest point, and up to more than 10 km across. [1] Drift ice is a floating field of sea ice composed of several ice floes.
Part 1 - (15 minutes) Polarstern Searches for a Suitable Ice Floe Use the Ice Floe Identification PPT to introduce students to the term, “ice floe” and to tell the story of the Polarstern searching for and attaching to a suitable ice floe. Part 2 - (40 minutes) Find Your Floe Jigsaw
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.
Together they store a volume of ice that, if completely melted, would cause global sea level to rise by around 65 metres. The ice sheets of West and East Antarctica have a combined ice volume of 26.37 million cubic kilometres, and the inland ice of Greenland around three million cubic kilometres.
An ice floe is any contiguous piece of sea ice. Floes are subdivided according to horizontal extent.
27 maj 2015 · The measurement of morphological properties of ice floes could inform us on key properties regarding the rheology of sea ice and help the reconstruction of the number of floes of a given...
