“…Low density plastics float on seawater. Residence time (floating) of litter in water column depends on the type of plastic and physicochemical conditions of water (Muthukumar et al 2011). In the present study, most of plastics separated from marine bottom sediments have greater density than seawater (Table 3).…”

Microplastics’ (particles size ≤5 mm) sources and fate in marine bottom and beach sediments of the brackish are strongly polluted Baltic Sea have been investigated. Microplastics were extracted using sodium chloride (1.2 g cm−3). Their qualitative identification was conducted using micro-Fourier-transform infrared spectroscopy (μFT-IR). Concentration of microplastics varied from 25 particles kg−1 d.w. at the open sea beach to 53 particles kg−1 d.w. at beaches of strongly urbanized bay. In bottom sediments, microplastics concentration was visibly lower compared to beach sediments (0–27 particles kg−1 d.w.) and decreased from the shore to the open, deep-sea regions. The most frequent microplastics dimensions ranged from 0.1 to 2.0 mm, and transparent fibers were predominant. Polyester, which is a popular fabrics component, was the most common type of microplastic in both marine bottom (50%) and beach sediments (27%). Additionally, poly(vinyl acetate) used in shipbuilding as well as poly(ethylene-propylene) used for packaging were numerous in marine bottom (25% of all polymers) and beach sediments (18% of all polymers). Polymer density seems to be an important factor influencing microplastics circulation. Low density plastic debris probably recirculates between beach sediments and seawater in a greater extent than higher density debris. Therefore, their deposition is potentially limited and physical degradation is favored. Consequently, low density microplastics concentration may be underestimated using current methods due to too small size of the debris. This influences also the findings of qualitative research of microplastics which provide the basis for conclusions about the sources of microplastics in the marine environment.

“…Studies of biofouling on EFMD are now going under a rising bloom of research and have been taking two main venues to understand the following: (1) succession time frames associated with it [55][56][57][58][59] and (2) its impact on the EFMD intrinsic capabilities to withstand on the surface water [27,56,57,60]. All those aspects are important to predict EFMD behavior and to better target the methods used for search and detection.…”

Exogenous floating marine debris (EFMD) is a worldwide concern and its ubiquitous characteristics and long-term threat have raised calls for new venues to enable easier and prompt detection at large. The main focus of this paper is to evidence search and detection methods for EFMD using remote sensing techniques. This paper contributes to update research information in the topic under scrutiny and to screen for possible gaps to mitigate EFMD impacts. Several needs for research were found, and, before any work to establish the ground truth could take place, a spectral library model for EFMD going through several stages of biofouling must be created using passive or active research methods. Search methods need to be automated using empirical models based on stratified set-ups previously tested. Several sensors show potential for an indirect search for EFMD, but direct detection of EFMD using multispectral and radar instruments still needs further research through integration with conceptual and empirical modeling techniques.

“…The formation of the microorganisms' colonies is known as the bio-fouling. According to recent tests, it was found that carbon fibre/epoxy resin composite has a higher chance to foul and deteriorate [90,91]. Although the tests results are highly site specific, the general behaviour should be more or less analogous.…”
