Formal education is essential to expand the reach of OL, providing people with tools to engage in coastal and marine issues consciously and knowingly. To this end, content analysis of school curricula can help planning strategies, especially to empower citizens to implement public policies. This study assessed the extent to which OL-related terms and words are present in Brazilian curricular documents at federal (National Curriculum Parameters-PCNs and Common National Curriculum Base-BNCC) and regional (Federative Units curricular guidelines-RCs) levels. Qualitative (content analysis) and quantitative analyses (descriptive and non-parametric statistics, and multivariate analysis) were performed. The number of occurrences of OL-related words and terms were registered and counted. Nineteen words were found, totaling 797 citations (a frequency of 0.0001 in the total number of words referring to content). The number of citations were higher in BNCC-based RCs than in PCN-based RCs (Kruskal-Wallis test, p = 0.0009). Principal component analysis separated the documents into two groups, one related to BNCC-based RCs of Northeast, North and Midwest regions, with a higher number of OL related terms, and the other group with the PCN based RCs of these same regions plus those documents of Southeast and South regions (principal component 1 explaining 97.90% of the total variation and having 0.93 correlation with the total frequency of citations). General results indicated that Brazilian production on fields and themes related to OL is still concentrated in national journals, books, and booklets, thus with a limited impact. In same way although school curricula in Brazil have a larger number of topics on marine environments than do other countries, they showed heterogeneity among Federative Units, but generally with the topics still representing a very small fraction of Brazilian curricula. Thus, it is necessary to expand the contents related to the ocean and marine environments in curricula to provide students with basic knowledge about the importance and functions of these environments, as well as their conservation. Therefore, results here emphasize the need to implement OL to highlight the importance of knowledge of the oceans and enable citizens to discuss marine conservation policies and promote ocean sustainability. This study provided some strategies to increase OL","PeriodicalId":19418,"journal":{"name":"Ocean and Coastal Research","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67342353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 115,505 kg of fish was harvested, distributed among 22 species. The flood period was the most representative, with a total of 43,122 kg, followed by the ebb period (28,749 kg), the rainy period (23,171 kg) and the dry period (20,424 kg). Kingfish ( Macrodon ancylodon ) was the most abundant fish in all seasons (79.7%). Significant differences were observed in fish composition in relation to the depth gradient and hydrodynamics of the Amazon River, with higher richness and diversity (Margalef index) during flood periods and at greater depths throughout the study period. We also observed a significant interaction between river flow and depth category, with more diversified fish fauna attributed to ebbs and floods in shallow and deep waters at the mouth of the Amazon River.

A broad way of defining and understanding the Earth’s “oceans, seas, coasts, and islands” is through a systemic vision that we define as a “Global Oceanic System-GOS”, which integrates and connects various marine spaces and the ocean as an organized unit. The ocean is a unique system connecting ecological, economic, social, and cultural components, through which goods and services regulate the planetary condition and support the development of mankind. However, its increasing use has followed the exponential growth of the global economic system, outpacing humanity’s ability to develop the knowledge necessary to establish a basis for its proper use. Hence, there is an added perception that our necessary knowledge about the functioning of the ocean for its appropriate planning and management, advances at a slow pace, with which the ocean would be losing quality and sustainability. Systemic views of the ocean tend to highlight dominant components and processes instead of structural details, establishing a quality shortcut to the knowledge where society can understand current and future ocean conditions. To achieve the desired ocean health and sustainability, we propose the formation of a base of knowledge of the marine and coastal environments, capable of supporting best practices and policies for planning and management. We drew from the interdisciplinary research developed by the Brazilian research group “Ecosystem-Based Marine and Coastal Management (Eco-MCM), ” which has been developing projects based on three fundamental steps: (1) systemic analysis of the marine and coastal environments, highlighting their ecosystems, ecosystem services, social and economic benefits produced by the services and the stakeholders benefited; (2) modeling of the studied systems, and (3) propositional phase to incorporate models to support the practices and policies for their planning, management, and governance. As such, they are aligned with the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) challenges and outcomes.","PeriodicalId":19418,"journal":{"name":"Ocean and Coastal Research","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67342007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although women are a fundamental part of the seafood supply chain in Brazil, fisheries management is gender-biased; sectoral programs and policies fail to recognize, support, and guarantee fisherwomen legal and labor rights. Brazilian fisherwomen have been very active in claiming their rights and recognition in the fisheries sector; however, public policies are lagging, and so are the studies that subsidize them. Within the UN Decade of Ocean Science for Sustainable Development and 2030 Agenda, it is critical to analyze the interactions between SDG 14 (Life below water) and SDG 5 (Gender equality) to discuss the gender dimensions underpinning fisheries (un)sustainability. We performed a systematic literature review and bibliometric analysis of gender-oriented studies in marine fisheries in Brazil. We identified 19 studies, published up to December 2020, focused on artisanal fisheries. The publications show that women are present in fisheries and are fundamental subjects to maintaining the activity and continuity of this livelihood. However, fisherwomen remain invisible. Their work is underreported, underpaid, and undervalued, which jeopardizes the sustainability of artisanal marine fisheries. Considering the knowledge gaps to be addressed during the Ocean Decade, we recommend that researchers and politicians work to: make \"hidden the hidden workforce visible; embrace interdisciplinarity; set gender-fo-cused research priorities; fill the data gap and promote public policies that support gender-equitable fisheries.","PeriodicalId":19418,"journal":{"name":"Ocean and Coastal Research","volume":"7 8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67342112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Canary Current Large Marine Ecosystem (CCLME) is characterised by a mix of the Atlantic Ocean basin waters, reverse flow from the Mediterranean Sea, and inland waters from adjacent countries. This biodiversity-rich ecosystem is a source of ecosystem goods and services that provide sustenance for populations in the coastal states of West Africa and beyond. However, with the ocean surface warming, ocean productivity and fisheries’ outputs have declined across multiple trophic levels. Therefore, in this diagnostic study based on a systematic literature review (publications from 2009 to 2020), we (a) provide an integrative assessment of the CCLME with the exception of Morocco, in the context of the modular large marine ecosystem framework using the categories ‘environmental’ (productivity, fish and fisheries, pollution, and ecosystem health) and ‘non-environmental’ (socioeconomic and governance), and (b) identify knowledge gaps and data scarce regions. The key drivers of change in the CCLME were identified as fishing pressure, land-based pollution, coastal habitat loss, and climate change. Productivity, land-based pollution, and ecosystem health were priority areas for data collection in the CCLME, with data deficiencies particularly apparent in The Gambia and Guinea. Therefore, to mitigate further degradation and accelerate progress toward sustainable management of the CCLME, research should be conducted in these priority areas of data deficiency. Furthermore, as most drivers of change in this ecosystem are related to weak management and a lack of regulatory enforcement, we recommend effective implementation, monitoring, and enforcement of existing national and transboundary regulations, as well as ecosystem-based human-centred management approaches, as proactive strategies for decoupling anthropogenic disturbances from climate change and optimising the productivity of the CCLME.","PeriodicalId":19418,"journal":{"name":"Ocean and Coastal Research","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67341995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the 1960’s, there has been a growing understanding of the importance of the ocean and for the need to implement actions to promote sustainable development (on the ocean and based on the ocean). More recently, important milestones were set. Aside from the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention, 1972), the International Convention for the Prevention of Pollution from Ships (MARPOL, 1973), and the United Nations Conference on the Law of the Sea (1982), the first worldwide and integrated movement that raised specific attention to the ocean sustainability was the Agenda 21, launched at the United Nations Conference on Environment and Development, held in 1992 in Rio de Janeiro (UNGA, 1992). From its 42 chapters, Chapter 17 [Protection of the oceans, all kinds of seas, including enclosed and semi-enclosed seas, and coastal areas and the protection, rational use, and development of their living resources] raised concerns relating to the various emerging threats that ocean health and sustainable use are facing. After ten years, at the United Nations Conference on Sustainable Development carried out in Johannesburg, South Africa, a highly structured global mechanism was proposed to regularly review the environmental, economic, and social aspects of the world’s ocean and to strengthen the regular scientific assessment of the state of the marine environment, to enhance the scientific basis for policymaking (UNGA, 2002). The “Regular process for global reporting and assessment of the state of the marine environment, including socio-economic aspects” was operationalized under the structure of the United Nations Convention on the Law of the Sea (UNGA, 2003). Two cycles of the Regular Process have already been concluded, creating World Ocean Assessments I and II (UN, 2017; UN, 2021). The World Ocean Assessments are based on the framework of the Millennium Ecosystem Assessment (MEA, 2005). They seek to deepen the information on the ocean that is being compiled and to critically analyze the outcomes of other processes such as the Intergovernmental Panel on Climate Change (IPCC), Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), and Global Environmental Outlook of the United Nations Environmental Program (UNEP/GEO). Given the ecosystem approach and considering the reliance of people on nature, ocean issues also emerged in the climate (IPCC, 2019) and biodiversity (CBD, 2011) Conference of Parties. In parallel to the World Ocean Assessment cycles, the United Nations Conference on Sustainable Development, held in Rio de Janeiro, Brazil, in 2012, created momentum for important actions relating to the ocean. Also called Rio +20, it evidenced the central role of the ocean in sustainable development in its final document, “The future we want” (UNGA, 2012).

We carried out a field survey where water level, currents, salinity, temperature, and suspended sediment concentration (SSC) were recorded at 10-minute intervals during two complete semi-diurnal tidal cycles under spring tide conditions. The field survey was conducted in September (2012), which is a transitional period between wet and dry seasons. The water level displayed symmetrical ebb-flood phases; however, currents were ebb-dominated. The freshwater contribution was negligible, and the mean salinity was ~35 g/kg, which is slightly lower than the adjacent shelf values (36.5 g/kg). The SSC transport was driven by the ebb-dominated tidal currents, with the highest values of ~30 mg/l occurring during the peak current during the ebb. The source of the suspended sediment was the erosion from the bottom, and the concentration was much lower than other similar estuaries (e.g., Caravelas). This observation suggests this system is a ‘sediment starved system’ in the sense that it presents a low concentration of suspended sediment.","PeriodicalId":19418,"journal":{"name":"Ocean and Coastal Research","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67342343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
