Beached and Floating Litter Surveys by Unmanned Aerial Vehicles: Operational Analogies and Differences

open access: yesRemote Sensing, 2022
The abundance of litter pollution in the marine environment has been increasing globally. Remote sensing techniques are valuable tools to advance knowledge on litter abundance, distribution and dynamics. Images collected by Unmanned Aerial Vehicles (UAV,

TOWARDS DETECTING FLOATING OBJECTS ON A GLOBAL SCALE WITH LEARNED SPATIAL FEATURES USING SENTINEL 2 [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
Marine litter is a growing problem that has been attracting attention and raising concerns over the last years. Significant quantities of plastic can be found in the oceans due to the unfiltered discharge of waste into rivers, poor waste management, or ...

Riverine Litter Flux to the Northeastern Part of the Black Sea

open access: yesJournal of Marine Science and Engineering, 2023
Rivers are among the main sources of marine litter, especially for semi-isolated sea areas with high populations and intense economic activity. The semi-isolated Black Sea located in the Eastern Europe is an example of such an area, whose watershed basin

Hyperspectral ultraviolet to shortwave infrared characteristics of marine-harvested, washed-ashore and virgin plastics [PDF]

open access: yesEarth System Science Data, 2020
Combating the imminent environmental problems associated with plastic litter requires a synergy of monitoring strategies, clean-up efforts, policymaking and interdisciplinary scientific research.

Modelling floating riverine litter in the south-eastern Bay of Biscay: a regional distribution from a seasonal perspective [PDF]

open access: yesOcean Science, 2022
Although rivers contribute to the flux of litter to the marine environment, estimates of riverine litter amounts and detailed studies on floating riverine litter behaviour once it has reached the sea are still scarce.

Floating Riverine Litter Flux to the White Sea: Seasonal Changes in Abundance and Composition

open access: yesJournal of Marine Science and Engineering, 2023
Arctic rivers bring litter from their basins to the sea, but accurate data for the Arctic do not exist yet. This study presents the first assessment of floating macro litter input (>2.5 cm) from the Northern Dvina and Onega rivers to the White Sea.

Marine Litter Distribution and Density in European Seas, from the Shelves to Deep Basins [PDF]

open access: yes, 2014
Anthropogenic litter is present in all marine habitats, from beaches to the most remote points in the oceans. On the seafloor, marine litter, particularly plastic, can accumulate in high densities with deleterious consequences for its inhabitants.

Chapter An integrated approach for marine litter hot spots identification

open access: yes, 2022
Marine litter is defined as any persistent, manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment, and it is among the most important environmental problems which are affecting the sea nowadays.

Unsteady Ekman‐Stokes Dynamics: Implications for Surface Wave‐Induced Drift of Floating Marine Litter [PDF]

open access: yesGeophysical Research Letters, 2020
Abstract We examine Stokes drift and wave‐induced transport of floating marine litter on the surface of a rotating ocean with a turbulent mixed layer. Due to Coriolis‐Stokes forcing and surface wave stress, a second‐order Eulerian‐mean flow forms, which must be added to the Stokes drift to obtain the correct wave‐induced Lagrangian ...
