弗拉姆海峡边缘冰带的连续遥感图像在阐明大气、海洋和海冰之间复杂的相互作用方面发挥了关键作用。对覆盖一周时间的这些图像的子集的分析提供了关于中尺度冰形态的定量数据，包括冰边缘位置、冰浓度、浮冰大小分布和冰运动学。分析表明，在微风到中风条件下，边缘冰带的形态反映了底层海洋环流。高分辨率雷达观测显示了冰缘附近海洋涡旋的位置和大小。来自连续雷达图像的冰运动学揭示了内部冰盖下的海洋涡流，这一点得到了现场海洋学测量的证实。
Sequential remote sensing images of the Fram Strait marginal ice zone played a key role in elucidating the complex interactions of the atmosphere, ocean, and sea ice. Analysis of a subset of these images covering a 1-week period provided quantitative data on the mesoscale ice morphology, including ice edge positions, ice concentrations, floe size distribution, and ice kinematics. The analysis showed that, under light to moderate wind conditions, the morphology of the marginal ice zone reflects the underlying ocean circulation. High-resolution radar observations showed the location and size of ocean eddies near the ice edge. Ice kinematics from sequential radar images revealed an ocean eddy beneath the interior pack ice that was verified by in situ oceanographic measurements.
