WebAug 13, 2024 · The Arctic sea ice cover is made up of discrete units of sea ice area called floes. The size of these floes has an impact on several sea ice processes including the volume of melt produced at floe edges, the momentum exchange between the sea ice, ocean, and atmosphere, and the mechanical response of the sea ice to stress. Models … WebSep 13, 2006 · [1] The ice pack covering northern seas is composed of a mixture of thick ridged and rafted ice, undeformed ice, and open water. Ice motions determined from satellite remote sensing data show that deformation of the pack takes place along the boundary of large floes. Eulerian continuum sea ice models can simulate this behavior to …
WebOct 1, 2024 · Microplastics are potentially captured by sea ice during the formation and drift of sea ice. Sea ice from the Beaufort, Chukchi, and East Siberian Seas can be included in the Beaufort cycle. Mobile sea ice floes in the Arctic Ocean can capture pollutants on the way of their drift and play a role in their redistribution due to possible release ...

WebA pressure ridge, when consisting of ice, is a linear pile-up of sea ice fragments formed in pack ice by accumulation in the convergence between floes. Such a pressure ridge develops in an ice cover as a result of a stress regime established within the plane of the ice. Within sea ice expanses, pressure ridges originate from the interaction ...
