In recent years the development of a global, Biogeochemical Argo observing system based on profiling floats has begun. The Southern Ocean Carbon and Climate Modeling (SOCCOM) program is the best example of this to date, and other groups are engaged in the development and deployment of such floats elsewhere in the world ocean as an essential next step for ocean science and marine resource management (see the report of the Biogeochemical Argo Planning Group, 2016). The development of the ideas, technology, and strategy for such an observing system has been developed through a series of working groups (Gruber et al., 2007), international meetings (Claustre et al., 2010; Gruber et al., 2010; Johnson et al., 2009), and AGU Town Hall meetings. Many of these activities were sponsored by OCB. There are a number of international groups and individuals that plan to purchase and deploy such floats in the coming years, in conjunction with large, global programs or as part of smaller projects that examine more local aspects of the oceanic carbon cycle. Despite this growing interest, at the present time the expertise necessary to procure, test, and deploy this technology is confined to a few centers. This workshop, sponsored by OCB, is being held in order to begin the process of transferring this expertise to the larger ocean carbon community by bringing together potential users of this technology to discuss biogeochemical profiling float technology, sensors, and data management, in order to begin the process of the intelligent design of future scientific experiments.
