Ocean waste mainly consists of artificial domestic waste, with a large proportion coming from the transportation of rivers on land. Since the United Nations initiated the sustainable development of the ocean in 2015, the management of ocean waste has gradually become a topic of great concern. By investigating, tracking the sources through statistics, and collecting the trajectory of floating marine debris through experiments, we can understand why marine waste becomes a hotspot. By using numerical models to trace back the trajectory, we can learn about the fantastic drifting journey of marine waste. In addition to being affected by ocean currents, marine waste is also affected by atmospheric wind, which is the interaction between the ocean and the atmosphere that affects the transmission path of global marine waste. This ocean-atmosphere interaction is what we call wind pressure difference. Various types, forms, densities, and volumes of marine waste all have different wind pressure difference coefficients, so by accumulating multiple sea experiments and collecting and establishing wind pressure differences, we can introduce numerical models to gain references for the management of marine waste. Therefore, the purpose of this project is to record the trajectory changes of floating objects of different shapes near the sea, combining on-site observations of ocean currents and meteorology to convert them into wind pressure difference data for numerical simulation and verification of drifting. We also plan to conduct experiments on the release and recovery of driftwood at river mouths, and to accumulate energy for tracking and tracing the drift of land-based and marine waste, enhancing our understanding of the distribution and sources of waste in our country's waters.
