Marine litter occurrence in the river-influenced Black Sea coast

, 2020
Composition and abundance of anthropogenic litter were investigated on adjacent coastal beaches of three rivers flowing into the North-Western and Southern Black Sea. A single sampling survey was conducted during the period August - September 2019 within

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Emerging Technologies for Remote Sensing of Floating and Submerged Plastic Litter

Remote Sensing
Most advances in the remote sensing of floating marine plastic litter have been made using passive remote-sensing techniques in the visible (VIS) to short-wave-infrared (SWIR) parts of the electromagnetic spectrum based on the spectral absorption ...

Synergistic and Trade‐Off Effects of Plant Communities on Slope Runoff and Sediment Yield

Land Degradation &Development, EarlyView.
ABSTRACT Plant community functional structure plays an important role in regulating slope runoff and sediment yield on the Loess Plateau. Based on runoff plot monitoring and vegetation surveys in the Yangjuangou catchment, we used partial least squares regression (PLSR) and variable importance in projection (VIP) analysis to assess the effects of ...

Marine protected areas invaded by floating anthropogenic litter: An example from the South Pacific

Aquatic Conservation: Marine and Freshwater Ecosystems, 2019
Abstract Oceanic marine protected areas (MPAs) that are close to the litter accumulation zones in the subtropical gyres receive large amounts of plastic litter, both as micro‐ and as macroplastics. The macro‐litter accumulating on the islands in the Easter Island Ecoregion (Rapa Nui and Salas y Gómez) can be traced back to the high seas industrial ...

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

Limnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

Limnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Proof of concept for a new sensor to monitor marine litter from space

Nature Communications
Worldwide, governments are implementing strategies to combat marine litter. However, their effectiveness is largely unknown because we lack tools to systematically monitor marine litter over broad spatio-temporal scales.

Knowledge about Microplastic in Mediterranean Tributary River Ecosystems: Lack of Data and Research Needs on Such a Crucial Marine Pollution Source

Journal of Marine Science and Engineering, 2020
Plastic debris occurring in freshwater environments, which can either come from the surrounding terrestrial areas or transported from upstream, has been identified as one of the main sources and routes of plastic pollution in marine systems. The ocean is

Floating Cities and Equitable Grafting onto Marine Ecosystems

, 2021
Based on current predictions of sea level rise and other climatic changes, in the near future, large urban coastal areas will no longer provide viable urban environments for human habitation. In response, floating city design proposals of various scales,
