Frontiers in Marine Science, 6, (2019): 570, doi:10.3389/fmars.2019.00570.The OceanObs conferences are held once every 10 years for the scientific, technical, and operational communities involved in the planning, implementation, and use of ocean observing systems. They serve to communicate progress, promote plans, and to define advances in ocean observing in response to societies' needs. Each conference provides a forum for the community to review the state of the ocean observing science and operations, and to define goals and plans to achieve over the next decade.The organizers of the OceanObs'19 conference thank the authors that conceived and jointly crafted the Community White Papers for their tremendous efforts, extensive international collaborations, and community wisdom. The organizers also thank the hundreds of reviewers of the CWPs for their dedication, and the time invested in reviewing the papers. The organizers of the OceanObs'19 conference wish to thank the chief editor of the journal, Dr. Carlos Duarte, and the Frontiers Marine Science staff, for their professionalism and support in this process
