Marginal ice zone

WebFeb 1, 2024 · The marginal ice zone (MIZ), characterized by partial ice cover, is the transition zone between the open ocean and the pack ice zone ( Johannessen, Johannessen, Svendsen, Shuchman, Campbell, Josberger, 1987, Kohout, Meylan, 2008 ). It is typically 100–200 km wide ( Häkkinen, 1986) and can extend for more than 200 km … WebApr 11, 2024 · Moreover, the polarization difference (PD, VV–HH) is found to be the foremost polarimetric parameter for distinguishing sea ice from open water. The proposed approach has capability of yielding satisfactory ice–water classification over the complicated marginal ice zone.

WebSep 12, 2024 · Perspectives are discussed on future directions for the field of marginal ice zone (MIZ) dynamics, based on the extraordinary progress made over the past decade in its theory, modelling and observations. Research themes are proposed that would shift the field’s focus towards the broader implications of MIZ dynamics in the climate system.

WebOct 10, 2024 · This is particularly relevant in the marginal ice zone (MIZ), which is a transitional region between the open ocean and pack ice, where the exchanges between ocean, sea ice and atmosphere are more intense. The MIZ is circumpolar and broader in the Antarctic than in the Arctic. WebAbstract. The Arctic marginal ice zone (MIZ), where strong interactions between sea ice, ocean and atmosphere take place, is expanding as the result of ongoing sea ice retreat. Yet, state-of-the-art models exhibit significant biases in their representation of the complex ocean–sea ice interactions taking place in the MIZ. Here, we present the development of …
