Open Geospatial Consortium (OGC) web services are quickly emerging as the near, real-time ocean data delivery standard. OGC services are changing rapidly as standards for various services are developed. A Principle Investigator on this proposed project, Michael Botts, heads an OGC development team at the University of Alabama, Huntsville (UAH). He also serves as Chair of the OGC Sensor Web Enablement Working Group. At the same time, requirements for quality ocean data are needed by a number of user groups such as the US Coast Guard and recreational boaters and standards are being developed to meet this need. A grass roots organization, called QARTOD (Quality Assurance in Real Time Oceanographic Data) has met regularly over the past few years, with support from NOAA, towards the definition of minimum requirements in QA/QC on four focus areas: waves, in situ currents, ctd and dissolved oxygen. The project authors propose to bring together the strengths of the UAH development team with researchers and data managers working in the oceanographic community. The authors propose to discuss and document the ocean data QA/QC requirements, as they relate to existing and potential OGC standards. Then, the development team at UAH will prepare a model of how these requirements can be implemented using existing standards. The project’s data managers will review and model any missing components. These recommendations will be reviewed by a sub-set of focus area experts (oceanographic researchers), as well as representatives from data centers (data providers) to affirm that a functional and feasible model has been described. Once the model is finalized, the UAH development team will design any required methods and generate a tutorial for implementation of an OGC-Service for the QA/QC of data for various sensors in the focus area (e.g., for waves, incorporate QA/QC information for wave-motion riders and acoustic instruments). The UAH team will also provide associated tools that evolve for the generation of QA/QC templates for each of the focus areas, facilitating implementation by participating data providers. In addition, tools to translate existing QA/QC data stored on servers using Open-source Project for a Network Data Access Protocol (OPeNDAP) to the OGC-Service will be developed and implemented The authors plan to test the results by implementing them through an existing OGC-Service, called Sensor Observations Service (SOS), at the Gulf of Maine Ocean Observatory System (GoMOOS) facility. The Martha’s Vineyard Coastal Observatory (MVCO) at the Woods Hole Oceanographic Institution (WHOI) and North Carolina Coastal Ocean Observing System (NCCOOS) at the University of North Carolina will implement QA/QC for waves, in situ currents and ctd and demonstrate the implementation using SOS. Both GoMOOS and MVCO plan to participate in the proposed New England Regional Association (NERACOOS) which is also requesting funding through this announcement (Section 1). Similarly, NCCOOS plans to participate in the proposed Southeastern Coastal Ocean Observations Regional Association (SECOORA). The bulk of the development effort will be done by UAH. Three or four meetings per year are proposed to gather requirements and review, test, and demonstrate work done by UAH. For each year of the proposal project there will be a focus area, first waves, then in situ currents and ctd, and in the final year, dissolved oxygen. Each focus area has unique QA/QC requirements which demand special attention.
