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.
12 wrz 2022 · 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.
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.
6 maj 2018 · The model presented here could help to answer questions on the seasonal evolution of floe size in the polar oceans, the possibility of power law emergence from interactions at the floe scale in a climate model, and the degree to which sea ice melting is influenced by fractured sea ice cover.
Sea ice covers about 7% of the ocean at any time, and makes up about 66% of the Earth’s permanent ice cover by area, but only 0.1% of the ice in terms of volume. This is because sea ice is a vast but thin sheet of cover compared to the glacial ice caps that are more localized but may be several kilometers thick.
20 lis 2014 · Dynamics and thermodynamics govern evolution of sea ice floe size distribution; Observations indicate major changes in the floe size distribution during summer; Floe breaking in summer increases the number of floes and total floe perimeter
Sea ice is a composite material made up of pure ice, liquid brine, air, and salt. The volumetric fractions of these components—ice, brine, and air—determine the key physical properties of sea ice, including thermal conductivity, heat capacity, latent heat, density, elastic modulus, and mechanical strength.
