Submesoscale ocean processes, which operate at spatial scales between mesoscale eddies and turbulence, are critical to the understanding of ocean circulation, heat distribution, and nutrient dynamics. However, due to their fine-scale nature, submesoscale dynamics remain challenging to study through traditional in-situ methods. This review examines the role of remote sensing in advancing our understanding of submesoscale processes, particularly in relation to ocean temperature and topography. We explore the application of satellite-based remote sensing technologies, including high-resolution ocean color, altimetry, and thermal infrared measurements, in capturing submesoscale features such as fronts, eddies, and filaments. We discuss how these techniques enable the monitoring of small-scale oceanographic phenomena that influence heat fluxes, ocean circulation patterns, and marine ecosystems. Additionally, the review highlights the integration of satellite data from platforms like Sentinel-3 and other Earth observation systems to track variations in ocean temperature, surface topography, and their relationships to submesoscale dynamics. By synthesizing recent advancements in remote sensing technologies and their applications to submesoscale oceanography, this review underscores the growing potential of remote sensing to bridge the gap between small-scale ocean processes and large-scale climate models, ultimately enhancing predictive capabilities and climate monitoring efforts.
