About this Research Topic
Typical ship surveys studying litter pollution rely on net trawling or visual counts over random line transects about one or more kilometers long, regardless the heterogeneity at smaller scale. Globally, the highest concentrations of floating macro-litter (> 2 cm in size) reported from the transect methods are on the order of 1 item per 1000 m2. However, we are aware that that macro-litter concentration easily reaches several orders of magnitude greater into the litter windrows. Such high litter densities may afford unique opportunities for the remote-sensing monitoring or for conducting mitigating actions. Furthermore, like the surface aggregations of plankton and natural debris, the now common litter windrows might act as attractants of marine life and hot spots of interaction between litter and organisms. Detection and monitoring of litter windrows might help to prevent contamination by litter of sensitive areas, whether by their natural value (e.g., marine protected areas) or economic activity (e.g., tourism, aquaculture, fishing).
From this Research Topic, we aim to promote multi and interdisciplinary research orientated towards the marine litter windrows as study target. Contributions might for instance provide insight into:
• Best methods for the detection, monitoring and sampling of micro- and macro-litter windrows
• Experimental manipulations simulating litter windrows
• Loading, compositions and concentrations of litter and natural debris inside and outside windrows
• Shapes and spatial patterns of litter windrows (dimensions, spatial arrangement, spacing, vertical extent)
• Formation times, persistence and mobility of litter windrows
• When (e.g. seasonality) and where litter windrows form
• Environmental conditions and mechanisms responsible for their formation
• Interactions between organisms (e.g. jellyfish, large predators) and litter windrows
• Experiences of cleanups of floating macro-litter
• Explorations to remotely sense litter windrows using satellites, planes, drones or other platforms
