Beach macro-litter monitoring and floating microplastic in a coastal area of Indonesia

Marine Pollution Bulletin, 2017
Qualitative analysis of the structures of the polymers composing floating plastic debris was performed using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and the aging of the debris was assessed by measuring carbonyl group formation on the particle surfaces.

Riverine transport of floating macro litter to the Southeastern Black Sea

2021
<p>Marine litter, especially plastic, is the fastest growing environmental problem in the Black Sea. Rivers are recognized as the major sources of litter in the basin, but information on the transport of litter by rivers is still limited. This study presents the first estimates of riverine floating macro-litter in the SE Black Sea (Turkey)

Real-Time Floating Marine Litter Detection on USV

2024 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea)
Marine litter is harmful to coastal and ocean environments for many reasons. Many devices have been developed in the last few years to recover as much litter as possible in ports and coastal areas. However, they usually employ a brute-force approach, leading to high energy and resource consumption.

Pond-bottom decomposition of leaf litters canopied by free-floating vegetation

Environmental Science and Pollution Research, 2019
In wetland ecosystems, vegetation can float freely on water surface, forming dense canopy which may play important ecological roles. This is especially true in many urban wetlands in which fluidity is low and nutrient level is high. So far, effects of free-floating vegetation on abiotic and biotic factors of wetlands have been known, while little on ...

Plastic Litter Project 2019: Exploring the Detection of Floating Plastic Litter Using Drones and Sentinel 2 Satellite Images

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The Plastic Litter Projects (PLP) are an innovative exploratory application of open-access satellite imagery and drone data for the remote detection of artificial floating marine plastic targets in natural waters. This paper presents the second PLP, conducted in the summer of 2019 within a two month period.

Modeling and Control of a Floating Marine Litter Collection Device

OCEANS 2025 Brest
Marine litter poses a significant environmental threat, with detrimental effects on marine ecosystems through toxic chemical release, entanglement, ingestion by marine life, and microplastic formation. Floating waste collection devices, such as the Waste Out of Water (WoW) system developed by the University of Florence, offer a solution by intercepting

Uncovering the relationship between floating marine litter and human activities in watersheds

Marine Pollution Bulletin
Rivers serve as the primary pathway for transporting floating marine litter (FML) from land to sea. However, the complex dynamics of transboundary rivers pose a significant obstacle when examining the impact of watershed-based human activities on FML distribution. This study conducts year-long monthly monitoring of FML using trawl and visual surveys in

Monitoring of floating macro litter in the Arctic seas and rivers

Among other marine environmental problems, the issue of marine litter accumulation in the World Oceans is of increased interest. It is relevant not only in areas with direct intense anthropogenic pressure, but also in remote and presumably pristine areas, such as the Arctic Sea. As the concentration of plastic waste in the marine environment increases,
