Measuring the sea ice floe size distribution
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.

The sea-ice floe size distribution (FSD) characterizes the sea-ice response to atmospheric and oceanic forcing and is important for understanding and modeling the evolving ice pack in a warming Arctic. FSDs are evaluated from 78 floe-segmented high-resolution (1 m) optical satellite images capturing a range of settings and …
WebMar 30, 2024 · To investigate the reason, the relative distribution histogram is derived and shown in Fig. 5, where TS-SLIC tends to extract more small floes within the size ranging from 10 to 100 pixels than the other three algorithms. This can also be obtained directly from the blue bounding box in Fig. 3.

WebWe develop and demonstrate a model for the evolution of the joint sea-ice floe size and thickness distribution that depends on atmospheric and oceanic forcing fields. The model accounts for effects due to multiple processes that are active in the MIZ and seasonal ice zones: freezing and melting along the lateral side and base of floes ...
