Coastal ocean observing and modelling systems (coastal observatories), connected with regional and global ocean systems, improve the quality of information and forecasts for effective management of safe and sustainable maritime activities. The public availability of systematic and long-term information of the ocean is an engine for the Blue Economy, boosting economic growth, employment, and innovation. An overview of some Brazilian initiatives is presented in this paper, involving universities, private companies, federal and state agencies, covering institutions from south to north of Brazil. Although these initiatives focus mainly on ocean physics, integrated efforts can extend the scope to include biogeochemistry and marine biodiversity, helping to address interdisciplinary problems. Existing initiatives can be connected, and new ones fostered, to fill in the gaps of temporal and spatial coverage of ocean monitoring in the vast oceanic area under Brazilian jurisdiction (nationally referred to as the Blue Amazon, in reference to the similar richness of the Amazon Forest). The alignment among national and regional initiatives, as well as with international programmes, can be promoted if coordinated by a national-level organization, maximizing the return of public investment and socioeconomic benefits. In light of international examples, possible future institutional arrangements are discussed, leveraging from existing national public policies and international cooperation that Brazil is taking part. The United Nations Decade of Ocean Science for Sustainable Development is a timely opportunity to encourage an institutional arrangement to support and articulate an integrated network of coastal observatories in Brazil.

巴西沿海海洋观测和建模系统：举措和未来展望

沿海海洋观测和建模系统（沿海观测站）与区域和全球海洋系统相连，提高了信息和预报的质量，以有效管理安全和可持续的海上活动。海洋系统和长期信息的公开可用性是蓝色经济的引擎，促进经济增长、就业和创新。本文概述了巴西的一些举措，涉及大学、私营公司、联邦和州机构，涵盖巴西从南到北的机构。尽管这些举措主要侧重于海洋物理学，但综合努力可以将范围扩大到包括生物地球化学和海洋生物多样性，从而有助于解决跨学科问题。可以连接现有的举措，并培养新的举措，填补巴西管辖下的广阔海域（国家称为蓝色亚马逊，参照亚马逊森林相似丰富度）海洋监测时空覆盖的空白。如果由国家级组织协调，可以促进国家和区域倡议之间以及与国际计划之间的协调，从而最大限度地提高公共投资和社会经济效益的回报。根据国际例子，利用巴西正在参与的现有国家公共政策和国际合作，讨论了未来可能的制度安排。
