“…No studies so far have compared areas of interest to determine statistical difference or change over time in a coastal setting. Various studies have addressed individual driving forces for plastic accumulation, such as surface currents and Ekman drift (Kubota, 1994;Martinez et al, 2009), rainfall (Carson et al, 2013), and winds (Kukulka et al, 2012). Carson et al (2013) indicated that nearshore and tidal dynamics might have important and variable effects on pollution retention in coastal areas.…”

Therefore, selecting areas characteristic of various physical drivers may create a better understanding of high variability over short time scales and inform approaches for successful longterm comparisons.…”

Plastic pollution in marine surface waters is prone to high spatial and temporal variability. As a result increases in pollution over time are hard to detect. Selecting areas, based on variable oceanographic and climatological drivers, rather than distance-based approaches, is proposed as a means to better understand the dynamics of this confounding variability in coastal environments. A pilot study conducted in Perth metropolitan waters aimed to explore the applicability of this approach, whilst quantifying levels of plastic pollution in an understudied part of the world. Pollution ranged from 950 to 60,000 pieces km −2 and was dominated by fishing line. Offshore concentrations were highest with strongest Leeuwin Current flow, in the estuary immediately after rainfall, and increased in the nearshore after estuarine outfall. Results elucidated significant relationships between physical drivers and concentration changes and therefore their roles in increasing or decreasing local plastic pollution. Such observations can form the basis for predicting peak pollution periods and inform targeted mitigation.

“…Nevertheless, it is obvious that the best methodology is one that adjusts to the main goal of study. In this respect, given that the detection of the areas where marine debris tend to deposit and the identification of its possible sources are among the objectives of the study, it is interesting to collect only the debris recently left by the sea, also known as "fresh debris" [17], [20], [21], and not the items left behind by beach users, or left by the sea a long time ago, which would make more difficult these tasks. In addition, different management actions are occurring on the study area, as is the case of the cleaning services efforts, which could seriously interfere with the sampling procedure if not taken into account.…”

“…All the collected debris was firstly rinsed off with water and left drying under normal temperature conditions, in a ventilated and protected from the direct sunlight effect room. Once debris was dried, the collected items were sorted and classified according to the following general categories: plastic, rubber, processed lumber, clothing/fabric, paper/cardboard, and metal [3], [21], [22] but with some small modifications. Cigarette butts were considered separately because of their predominant occurrence in comparison with the rests of the groups.…”

An approach to the spatial and temporal distribution of marine debris stranded on Las Canteras Beach is developed by means of surveys carried out during one year, along three transects located on the southern, northern, and central parts of the beach. Results evidence that debris stranded on the beach represent an almost permanent type of pollution, but with a large time variability in the number of items observed along the three transects, as well as in the type and origin of the debris collected at the different stretches of the beach.

“…Regional studies on litter transport are very few compared to large scale ones; they are limited to the East Asian marginal seas and the ocean surrounding Hawaiian Islands (among the most recent, respectively, Carson et al, 2013;Kako et al, 2014). In the Mediterranean, several studies investigated the abundance of debris (see again CIESM, 2014, for comprehensive reviews), while studies on its transport are scarce.…”
