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.
Key results are: (i) a rapid final fall in global sea level of ∼40 m in <2,000 y at the onset of the glacial maximum ∼30,000 y before present (30 ka BP); (ii) a slow fall to −134 m from 29 to 21 ka BP with a maximum grounded ice volume of ∼52 × 10 6 km 3 greater than today; (iii) after an initial short duration rapid rise and a short ...
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.
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.
Figure 14.1.1 An iceberg (glacial ice) embedded in a thinner layer of sea ice (NASA / James Yungel [Public domain], via Wikimedia Commons). Sea ice cover around Antarctica fluctuates between about 21 million km 2 in winter to around 1.3 million km 2 in the summer, with most Antarctic sea ice lasting only a year.
20 lis 2014 · Key Points: 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. 1 Introduction.
These data sets show grids of sea ice concentrations, as well as summaries using data from SMMR, SSM/I, and SSMIS depicting annual cycles of ice extent (areas with at least 15 percent ice cover), ice covered area (the ocean area actually covered by ice), and departures from monthly averages.
