To what extent can satellite-based geo-mapping technologies detect, monitor, and quantify microplastic pollution in marine environments, and what are the key limitations in spatial resolution, spectral differentiation, and data validation that constrain their efficacy?

  • Which satellite sensors are suitable for detecting ocean microplastics?
  • How well can satellites distinguish microplastics from other floating materials?
  • What are the spatial and temporal resolution limits for detecting microplastics?
  • How do environmental factors affect satellite detection accuracy?
  • How is satellite data validated with ground-based sampling?
  • Can GIS models effectively map and predict microplastic hotspots?
  • What are the key technical and methodological limitations of satellite-based microplastic monitoring?
  • How can emerging technologies improve current satellite monitoring gaps?
