Abstract Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in poorly mapped, and most of waste estimated to have entered from land unaccounted for. Better understanding how transported coastal marine sources crucial quantify close global inventory plastics, which turn represents critical information for mitigation or policy strategies. At same time, unique tracer that provides an opportunity learn more about physics dynamics our...
Plastics and other artificial materials pose new risks to health of the ocean. Anthropogenic debris travels across large distances is ubiquitous in water on shorelines, yet, observations its sources, composition, pathways distributions ocean are very sparse inaccurate. Total amounts plastics man-made shore, temporal trends these under exponentially increasing production, as well degradation processes, vertical fluxes time scales largely unknown. Present circulation models not able accurately...
Marine beaches worldwide are nowadays exposed to significant contamination by plastics. On the Baltic beaches, polyethylene, polypropylene, and polystyrene most abundant. We investigate generation of microplastics particles (MPs, characteristic size from 0.5 5 mm) larger plastic items in sea swash zone using a laboratory rotating mixer filled with water natural coarse beach sediment (marine pebbles). Inclination axis rotation volume material were adjusted such way that mixing resembled...
Abstract. In the Baltic Sea, salinity and its large variability, both horizontal vertical, are key physical factors in determining overall stratification conditions. addition to that, changes also have effects on various ecosystem processes. Several determine observed two-layer vertical structure of salinity. Due excess river runoff sea, there is a continuous outflow water masses surface layer with compensating inflow lower layer. Also, net precipitation plays role balance consequently...
Abstract Marine microplastic particles (MPs, <5 mm) exhibit wide ranges of densities, sizes, and shapes, so that the entire MPs “ensemble” at every time instant can be characterized by continuous distributions these parameters. Accordingly, this community demonstrates dynamical properties, such as sinking or rising velocity, critical shear stress, re-suspension threshold. Moreover, all MPs’ properties vary significantly with spent in marine environment particular conditions experienced...
Abstract Microplastic particles (MPs, <5 mm) are found in marine ice larger quantities than seawater, however, the distribution pattern within cores is not consistent. To get insights into most general physical processes behind interactions of and plastic cool natural environments, information from academic applied research integrated verified against available field observations. Non-polar molecules common-market plastics hydrophobic, so MPs weak nucleators, repelled water ice,...
Most marine litter monitoring methods used on beaches focus macro-litter (&gt;25 mm) only and show shortcomings regarding smaller classes (&lt;25 mm), especially at Baltic Sea beaches. Therefore, we a sand rake method developed for large micro- (2–5 meso- (5–25 to quantify the overall pollution status of test if is useful in terms requirements Marine Strategy Framework Directive (MSFD). Between July 2017 October 2019, 197 surveys were carried out 35 regions around Sea. In total, 9345...
Synthetic fibers with diameters of several tens micrometers are the most abundant type microplastics in marine environment, yet unknown regarding dynamics water column. Experiments proposed here a proof-of-concept qualitative and quantitative characteristics fibers' motion still presence thermal convection. For 12 sets fine (nylon (1.12 g/cm3) polyester (1.35 g/cm3), 1.9–14.8 mm long, 13 20 μm), 84 measurements sinking velocity were acquired. In conditions, settled smoothly slowly,...
The contamination by microplastics particles (MPs, 0.2-5 mm) in bottom sediments of the Baltic Sea is quantified. In total, 53 sediment samples were obtained 8 cruises research vessels July-October 2015 and March-December 2016. depths from 3 to 215 m Gotland, Gdansk, Bornholm Basins are covered. Primary data provided, along with exhaustive information on sampling dates coordinates, depths, methods, extracting procedures, control measures, detection techniques, verification μ-Raman...
A data set of closely spaced CTD profiling performed aboard Russian and Polish research vessels during 1993–2009 numerical modeling are applied to study the variability in asymmetric transverse structure salinity/density Słupsk Furrow (SF) overflow Baltic Sea. The simulations show that, on one hand, may be dynamically treated within SF as a subcritical, eddy‐producing gravity current wide channel, other, at sill displays some features peculiar frictionally controlled rotating flows....
