research, led by @Geraldo Mihut (@PlastCenterDanmark) and Mirco Haseler (@Leibniz-Institut f\u00fcr Ostseeforschung Warnem\u00fcnde), represents the first continuous 24-hour dataset of floating macro-litter collected in Denmark and across the Baltic region \ud83c\udf0d.<\/p>\n<p>Using the SeaProtectorOne interception device (developed by @<em>AllInOnGreenApS<\/em>), we recorded and categorised over 80,000 individual litter items across two comparable monitoring campaigns \u2014 enabling detailed analysis of temporal variation, material composition, and potential litter sources.<\/p>\n<p>The study also benefitted from the valuable contribution of @TeknikogMilj\u00f8, who were responsible for emptying the SeaProtectorOne and systematically recording the collected litter \u2014 an essential component of the research process.<\/p>\n<p>\ud83d\udd0d Key findings:<\/p>\n<ul>\n<li>\ud83e\uddfe 63,035 items were collected in 2021\/22 and 18,725 items in 2024\/25 \u2014 a &gt;70% reduction in total litter load.<br \/>\n\u2022 \ud83e\uddc3 Plastics remained the dominant material (~60%), followed by paper\/cardboard (~23%) and metal (~10%).<br \/>\n\u2022 \ud83d\udcc5 Litter peaks occurred on weekends, reflecting social and recreational activity patterns.<br \/>\n\u2022 \ud83c\udf3f The reduction likely results from a combination of EU-level policies, local prevention efforts, and growing public awareness.<\/li>\n<\/ul>\n<p>This work demonstrates the importance of continuous, high-frequency monitoring for understanding litter dynamics and evaluating the effectiveness of mitigation strategies.<br \/>\nSuch long-term datasets provide critical input for policy design, urban litter management, and circular economy development in riverine and coastal systems.<\/p>\n<p>The study was conducted within the @Circular Ocean-bound Plastic project under the @InterregSouthBalticProgramme, showcasing how cross-sector collaboration \u2014 between
