Detection and Monitoring of Marine Pollution Using Remote Sensing Technologies
AI summary Read the abstract
This review examined satellite remote sensing technologies for detecting and monitoring marine pollution including oil spills, HABs, plastic debris, and sediment plumes, covering different sensor types and their capabilities. The authors identify current limitations of resolution and revisit frequency as key barriers to routine remote monitoring of microplastic pollution.
Recently, the marine habitat has been under pollution threat, which impacts many human activities as well as human life. Increasing concerns about pollution levels in the oceans and coastal regions have led to multiple approaches for measuring and mitigating marine pollution, in order to achieve sustainable marine water quality. Satellite remote sensing, covering large and remote areas, is considered useful for detecting and monitoring marine pollution. Recent developments in sensor technologies have transformed remote sensing into an effective means of monitoring marine areas. Different remote sensing platforms and sensors have their own capabilities for mapping and monitoring water pollution of different types, characteristics, and concentrations. This chapter will discuss and elaborate the merits and limitations of these remote sensing techniques for mapping oil pollutants, suspended solid concentrations, algal blooms, and floating plastic waste in marine waters.

A Global Review of Progress in Remote Sensing and Monitoring of Marine Pollution
AI summary Read the abstract
This review examines how remote sensing technology, including satellites and drones, is being used to monitor marine pollution such as oil spills, floating debris, and microplastics. While the technology works well for detecting large-scale pollution, methods for tracking microplastics in the ocean are still in early development. Better monitoring tools are needed to understand the full scope of marine microplastic pollution, which ultimately affects seafood safety and human health.

On advances, challenges and potentials of remote sensing image analysis in marine debris and suspected plastics monitoring
AI summary Read the abstract
This review evaluates the current state of satellite and aerial remote sensing for detecting marine plastic debris, noting that while progress has been made using optical and hyperspectral imaging, significant challenges remain including low detection resolution for small particles, confusion with other floating materials, and the need for better machine learning algorithms. The paper is relevant to the microplastics field as large-scale monitoring tools are needed to track plastic pollution distribution and inform cleanup and policy efforts, though direct detection of microplastics (<5 mm) from orbit remains largely out of reach with current technology.
