Deriving Sea Surface Currents from Satellite Measurements

Measuring and mapping sea surface currents is crucial in today's climate, not only for navigation but also for water body monitoring, pollution and climate change induced changes assessment, biodiversity conservation, and search and rescue operations. Non-invasive methods based on remote sensing offer more precise results compared to traditional approaches that are based on drifters and sensor installments. Satellite remote sensing enables global data coverage and inspires Earth observation applications across diverse sectors. In this paper a comprehensive overview of satellite-based approaches for assessing sea surface currents is presented. Through an analysis structured around a semantic conceptual framework, the current state of the art is examined, and further opportunities for future exploration are identified.
