Sea ice involves a wide range of scales making measuring the evolution and implementing models to predict its future state very complex. In this talk, I will give a brief summary of remote sensing techniques for sea ice, the state of the Arctic sea ice, and the importance of measuring small-scale ice features. New opportunities for Arctic-wide observations of evolving summer sea ice conditions are available with the launch of earth observing satellites with higher-resolution capabilities and continuous measurements. Analysis of ICESat-2 and Sentinel-2 data reveal a three dimensional view of the evolving ice cover, giving us insights on sea ice summer melt on a basin scale. We also explore new techniques for observing and tracking individual ice floes to describe a relationship between dynamical processes and floe size distributions for the first time. I will end by discussing the need to synthesize sea ice observations from varying scales, instruments, methodologies, and disciplines for an inclusive view of the sea ice cover.
