In this study, we investigated the acoustic signals produced by seagrass and its epiphytic algae during photosynthesis in a seagrass bed at Li'an Port, Hainan Province, China. Photosynthetic bubbles formed monopole sound sources, and we employed passive acoustic monitoring (PAM) technology at two sites to capture associated acoustic signals. Single pulses were detected and extracted using a neural network. Acoustic signal rates rose during non-photosynthetic periods, coinciding with wave breaking, human activities, or biological disturbances. We then manually checked the signals and removed the pulses from these interference processes throughout the 19-day recording period to specifically focus on analyzing the photosynthesis signals. The acoustic characteristics, including sound pressure level (SPL), duration, peak frequency, and −3 dB bandwidth were analyzed to assess differences between the sites. Photosynthesis-related acoustic signal rates peaked in the afternoon, and its average signal rate showed a roughly parallel trend to that of dissolved oxygen (DO) and temperature. These findings suggest that PAM of photosynthetic bubbles revealed another biological component of the overall ocean soundscape.

In the Netherlands a coastline maintenance policy was implemented in the 1990's to address the negative effects of erosion, with sand nourishments as the primary means. In this study, the cumulative effects of these nourishments are evaluated against the strategic goal of sustainable preservation of the uses and values of the coast. This research aims to inform national and international policy makers, practitioners, and scientist about the possible long-term effects of coastal management with structural sand nourishments. Coastal indicators were analysed to quantify the morphological evolution of the coast before and since coastline maintenance. It is observed that regular nourishments serve to halt structural coastline retreat. The coastline built out, on average, which was necessary to achieve maintenance of the most erosive areas. Additionally, strong dune growth is observed since the start of coastline maintenance, thanks to wind-driven transport of nourished sand and more dynamic dune management. Nourishments thus contribute positively to flood safety, although flood safety is not an automatic benefit of coastline maintenance. Space for recreation and nature is maintained or improved: the dry beach width was unaffected, and dune areas have grown. Further, it is reported that the impact of nourishments on the coastal ecosystem is local and temporary, leading to the inference that uses and values of the coast are being maintained sustainably through regular nourishments. Overall, the approach of coastline maintenance with regular pro-active nourishments has thus proven to be successful.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107895"},"PeriodicalIF":5.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines how governance structures can enable or hinder innovation in emerging blue bioeconomy systems, focusing on the valorisation of fishery side-streams and microalgae development. Using a novel Governance of Innovation Systems (GOIS) framework adapted from Technological Innovation Systems theory, we analyse governance structures across four European regions: Sicily (Italy), Saaremaa (Estonia), Greenland and West Jutland (Denmark). Through desk research and 18 stakeholder interviews, we identify key barriers and enablers within six governance functions: knowledge development, direction of search, legitimacy creation, resource mobilisation, market formation and entrepreneurial experimentation. Our findings reveal that while market formation shows promise across regions, significant challenges persist in legitimacy creation and knowledge development. Regulatory complexity and fragmented responsibilities emerge as primary barriers to innovation, particularly affecting small and medium-sized enterprises. Resource constraints manifest differently across regions, from infrastructure limitations in Sicily to workforce shortages in Denmark and Estonia. Based on these insights, we propose three key policy interventions: regulatory process simplification through sandboxes and administrative one-stop shops, innovative financing mechanisms including blue bonds and accelerator programs, and enhanced collaborative frameworks through regional networks and public-private partnerships. This study contributes to innovation systems theory and practice by demonstrating how systematic analysis of governance functions can inform targeted interventions to support sustainable blue bioeconomy development.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107899"},"PeriodicalIF":5.4,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fill these gaps, we examine the third round of China’s MSP, using nearshore seawater pollution data to assess its effectiveness in addressing transboundary environmental issues. An ordinary least squares regression model was employed to identify boundary effects in nearshore seawater pollution in China from 2008 to 2021, with a focus on active phosphate and chemical oxygen demand. A difference-in-differences model was used to evaluate the impact of this round of MSP on these boundary effects. The results showed that the policy did not mitigate the boundary effects; instead, it significantly worsened the levels of active phosphate and chemical oxygen demand. Further analysis using a planning scheme-based evaluation method revealed conflict and intensity values across 51 coastal cities, demonstrating that these values positively moderated the boundary effect. The findings highlight the importance of geographical location in nearshore seawater quality and the necessity of coordination in transboundary marine area planning to mitigate transboundary environmental risks.
