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.
Once ice floes form, the water underneath becomes insulated and heat loss to the atmosphere declines, so the water no longer cools and no more ice formation occurs. As a result, young sea ice is usually relatively thin, not more than 3-4 m thick.
12 wrz 2022 · Abstract. Marginal ice zones (MIZs) are qualitatively distinct sea-ice-covered areas that play a critical role in the interaction between the polar oceans and the broader Earth system. MIZ regions have high spatial and temporal variability in oceanic, atmospheric and ecological conditions.
1 lis 2020 · A one-dimensional sea ice dynamics model was conducted accounting for the contribution of ice floe size, wind and current to simulate the interaction of a vertically sided offshore structure and a drifting ice floe based on the nonlinear speed-dependent brittle and ductile deformation and local crushing of ice phenomenologically (Hendrikse and ...
Bigger ocean waves affect the way sea ice forms, contribute to how the ice edge moves, penetrate farther into the sea ice, have more destructive power to break up the ice and to change the distribution of floe sizes because the ice is weaker, and assist in lateral melting.
Detection, classification, and motion analysis of thin ice floes in open water bodies became reality with the development of advanced texture analysis techniques and ice-motion algorithms. The use of texture analysis considerably improved the contrast between ice and open water.
12 wrz 2022 · The marginal ice zone (MIZ) is the dynamic interface between the open ocean and sea ice-covered ocean. It is characterized by interactions between surface gravity waves and granular ice covers consisting of relatively small, thin chunks of sea ice known as floes.
