But you may be struggling to understand some of the finer details of melting ice, such as the difference between icebergs and ice floe. 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.
While it is true that both glaciers and ice floes are large masses of ice that can be found in arctic regions, there is a major difference between them. Basically, glaciers originate on land, and ice floes form in open water and are a form of sea ice.
Compared to visible imagery—showing what appears to human eyes—infrared imagery can better distinguish between ice and snow (turquoise), and clouds (nearly white). — Credit: NASA Worldview. Satellite sensors that measure infrared radiation infer the amount of heat emitted from Earth.
18 sie 2022 · The difference between sea ice and ice shelves is that sea ice is free-floating; the sea freezes and unfreezes each year, whereas ice shelves are firmly attached to the land. Sea ice contains icebergs, thin sea ice and thicker multi-year sea ice (frozen sea water that has survived several summer melt seasons, getting thicker as more ice is ...
5 lut 2018 · Icebergs are floating pieces that have broken off from larger ice shelves. They can be big enough to sink the Titanic or land a helicopter on, or small enough to fit into a glass. They can also come in many colors, depending on the compression of ice crystals and the presence of dirt, rock, and algae.
Depending on the marine area in which the giant icebergs have calved, they take one of four major routes that all drifting ice follows, both sea ice and icebergs, into warmer climes. GPS data have shown that one large iceberg has even been able to completely circumnavigate Antarctica.
The ice that is seen floating on the ocean’s surface comes from one of two sources. Glacial ice is formed from the accumulation and compression of snow into glaciers, that then break apart and release ice to the ocean.
