Monitoring Ocean Pollution: A Comprehensive Review of Satellite Image Analysis Methods
AI summary Read the abstract
This review paper looks at how satellites can be used to spot and track floating plastic waste in coastal waters, offering a faster and more efficient alternative to sending out boats or planes to survey pollution by hand. This matters because ocean plastic doesn't just harm marine life—it breaks down into microplastics that enter the food chain, potentially ending up on our plates, and it can leach toxic chemicals into the water we and marine animals depend on. Better satellite tracking could help identify pollution hotspots faster, making cleanup and prevention efforts more targeted and effective.
The proliferation of plastic pollution in coastal marine environments has emerged as a significant environmental issue, garnering global focus due to its detrimental impacts on marine ecosystems, human health, and economic endeavors.Coastal regions, characterized by the interaction between terrestrial ecosystems and marine environments, exhibit heightened vulnerability to the accumulation of plastic waste.The origins of this pollution are multifaceted, encompassing terrestrial activities characterized by inadequate waste management, the discharge of industrial effluents, contributions from precipitation, and inputs from river systems.Additionally, marine sources play a significant role, particularly those associated with the fishing industry and various maritime activities.The presence of plastic litter, which includes both large, discernible items and minute particles, poses considerable threats to marine organisms.The ingestion or entanglement of marine species, encompassing organisms from plankton to large mammals, in plastic debris leads to significant injuries, increased mortality rates, and disruptions within their respective food chains.Furthermore, plastics present in marine ecosystems have the capacity to absorb and disseminate toxic chemicals, thereby exacerbating the degradation of aquatic habitats.The ongoing challenges associated with the surveillance and regulation of plastic pollution in marine environments remain a significant concern.Traditional methodologies, such as in-situ sampling and airborne surveys, often present challenges related to labor intensity, time consumption, and limitations in both temporal and spatial dimensions.This scenario presents Earth observation (EO) imagery obtained from satellites as a feasible alternative.Satellites equipped with optical sensors offer a unique vantage point, enabling extensive surveillance of plastic waste distribution across extensive coastal areas with increased temporal resolution.This study investigates the utilization of data from the European Space Agency's Sentinel-2 satellite for the identification and monitoring of floating macro plastics in coastal waterways.The present study aims to evaluate the precision and effectiveness of plastic waste detection utilizing sophisticated remote sensing techniques and machine learning algorithms.

Implementing AI in Ocean Waste Tracking and Management
AI summary Read the abstract
This review paper looks at how artificial intelligence, like satellite image analysis, can help spot and clean up ocean pollution such as plastic waste and oil spills more efficiently than traditional methods. This matters because ocean plastic breaks down into microplastics that enter the seafood we eat and even our drinking water, so better detection and cleanup could mean less of this pollution ending up in our bodies. The authors note that AI isn't a perfect fix yet, it requires huge amounts of data and has its own environmental costs, like energy use, so more research and teamwork across science, government, and industry are still needed.
Implementing AI in Ocean Waste Tracking and Management
AI summary Read the abstract
This review paper looks at how artificial intelligence, like satellite image analysis and smart tracking systems, can help spot and clean up ocean pollution, including plastic waste and oil spills, faster and more accurately than older methods. This matters because ocean plastic breaks down into microplastics that end up in seafood and drinking water, so better cleanup technology could mean less of that pollution making its way into our bodies. That said, this is a summary of existing studies rather than new experiments, and the authors note that AI tools still need more data, cross-team collaboration, and attention to their own environmental costs before they can fully deliver on this promise.
AI for Monitoring Ocean Plastic Pollution
AI summary Read the abstract
This review assessed how artificial intelligence technologies—including satellite image analysis, computer vision, and machine learning—are being applied to monitor ocean plastic pollution. The authors found AI can dramatically expand spatial coverage and detection speed compared to traditional ship-based surveys, though ground-truth validation and data standardization remain challenges.
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.
A Comparative Analysis of AI-Driven Marine Debris Detection Methods for Indian Ocean Plastic Monitoring
AI summary Read the abstract
This review paper looked at 25 studies using satellite images and AI to spot floating plastic trash in the ocean, with a focus on India's coastline. It found that simpler, cheaper detection methods actually work quite well (86-98% accurate), but research on Indian waters is still patchy and hard to compare, meaning there's no reliable, affordable system yet to track where ocean plastic is heading before it breaks down into microplastics that can end up in seafood and drinking water. Better, low-cost monitoring tools could help catch plastic pollution before it enters the food chain.
