“…Based on our qualitative analysis and on the results of and Haarr et al (2019), we suggest a general division of deposition zones at beaches (Figure 3). We adhere to this division when describing our results.…”

“…Onshore accumulation of marine plastic is controlled by ocean currents, tidal movements, wind and coastal shape. Important geographical properties that control deposition include shape and orientation of the bay, shoreline slope and substratum (Haarr et al, 2019). Plastic accumulation in western Norway is localized into bays and coves .…”

Frontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

“…In e.g. Haarr et al (2019) and Hardesty et al (2017), it was reported that large scale headlands tend to enhance catchment of litter compared to large scale sheltered areas. This is in line with our findings, with an increasing n grid •n leading to more predicted litter (see Appendix B5).…”

“…The accelerated increase of mismanaged plastic waste into the global ocean gives rise to the need of effective cleanup strategies (Ogunola et al, 2018). In order to minimize the negative impact of plastic pollution on the environment, cleanup strategies need to be optimized to target the most impacted areas while limiting the economic costs (Haarr et al, 2019;Newman et al, 2015).…”

Abstract. Coastlines potentially harbor a large part of litter entering the oceans such as plastic waste. The relative importance of the physical processes that influence the beaching of litter is still relatively unknown. Here, we investigate the beaching of litter by analyzing a data set of litter gathered along the Dutch North Sea coast during extensive beach cleanup efforts between the years 2014–2019. This data set is unique in the sense that data is gathered consistently over various years by many volunteers (a total of 14,000), on beaches which are quite similar in substrate (sandy). This makes the data set valuable to identify what environmental variables might play an important role in the beaching process, and to explore the variability of beach litter. We investigate this by fitting a random forest machine learning regression model to the observed litter concentrations. We find that especially tides play an important role, where an increasing tidal variability and tidal height lead to less litter found on beaches. Relatively straight and exposed coastlines appear to accumulate more litter. The regression model indicates that transport of litter through the marine environment is also important in explaining beach litter variability. By understanding what processes cause the accumulation of litter on the coast, recommendations can be given for more effective removal of litter from the marine environment. We estimate that 16,000–31,400 kilograms (95 % confidence interval) of litter are located on the 365 kilometers of Dutch North Sea coastline.

“…Citizen science data collection presents numerous potential sources of error such as: observer bias, poor and inconsistent tagging of items, lack of standardisation of collection methods, regional biases in effort, and temporal variation in effort 43,44 . However, observed trends within and between nations in relation to national legislation and the WHO's declarations are evident, supporting the use of citizen science in understanding widespread geographic and temporal events.…”

Personal protection equipment was adopted during the COVID-19 pandemic to reduce transmission of the virus. However, masks, gloves and wipes must be disposed of responsibly. Anecdotal accounts of litter throughout 2020 suggest an environmental legacy to mismanaged PPE. Here we show the emergence of COVID-related litter over a 14-month period using the citizen science application Litterati. Observational data suggests that face mask litter became a new litter type as a result of COVID-19 legislation, increasing from <0.01% to over 0.8% in the countries observed. Glove and wipe litter was already prevalent at around 0.2% prior to the pandemic, doubling to around 0.4% throughout the pandemic. Citizen science enabled observation of littering behaviours between nations, highlighting where transferable practice could be beneficial in reducing littering impacts in other nations.
