Marine debris is a burgeoning global issue with economic, ecological and aesthetic impacts. While there are many studies now addressing this topic, the influence of urbanisation factors such as local population density, stormwater drains and roads on the distribution of coastal litter remains poorly understood. To address this knowledge gap, we carried out standardized surveys at 224 transect s...

Marine debris is a global environmental issue. Smoked cigarette filters are the predominant coastal litter item; 4.5 trillion are littered annually, presenting a source of bioplastic microfibres (cellulose acetate) and harmful toxicants to marine environments. Despite the human health risks associated with smoking, little is known of the hazards cigarette filters present to marine life. Here we...

Plastic debris has significant environmental and economic impacts in marine systems. Monitoring is crucial to assess the efficacy of measures implemented to reduce the abundance of plastic debris, but it is complicated by large spatial and temporal heterogeneity in the amounts of plastic debris and by our limited understanding of the pathways followed by plastic debris and its long-term fate. T...

This research was conducted in August – September 2020, at the Quality of Aquaculture Laboratory, Fisheries and Marine Faculty, Riau University. The purposed this study to see effect addition booster manstap density cell Chlorella sp. best dose for cultures uses a completely randomized design (CRD) with one factor, four treatments, three replications. treatment use different doses (BMD), namely...

Plastic debris is ubiquitous in all ecosystems and has even reached locations that humans will hardly reach such as the deep ocean floor atmosphere. Research highlighted plastic now pervasive remote Arctic regions. While modeling projections indicated local sources long-distance transport causes, empirical data about its origin are scarce. Data collected by citizen scientists can increase scale...

A global ocean circulation model is coupled to a particle-tracking model to simulate the transport of floating debris washed into the North Pacific Ocean by the Tohoku tsunami. A release scenario for the tsunami debris is based on coastal population and measured tsunami runup. Archived 2011/2012 hindcast current data is used to model the transport of debris since the tsunami, while data from 20...

Solid Marine Wastes present on the seabed and floating on the sea surface were investigated in the Aegean Sea. Compared to other locations in the Mediterranean, litter concentration on Northern to Mid Aegean Seabed is moderate even in populated gulfs, whereas floating marine debris concentrations are low and dominated by recreational items, probably restricted to summer season.
