• Open Geospatial Consortium (OGC) Sensor Web Enablement - SWE protocols provide the interoperability interfaces and metadata encodings that enable real time integration of heterogeneous sensor webs.
• OCEANS IE - an OGC Interoperability Experiment engaging data managers and scientists in the Ocean-Observing community.
• OpenIOOS Interoperability Testbed - a community demonstration of interoperability. The site hosts the demonstration and provides information about the project.
• OOSTethys - a community effort to develop easy-to-use, open-source, standards-based software to enable a "system-of-systems" of linked data providers in the marine domain based on standards developed by the Open Geospatial Consortium.
• The Marine Metadata Initiative - a collaborative effort to develop metadata standards. The site identifies best practices to make science data easy to distribute, advertise, reuse and combine with other data sets.
• The NOAA Coastal Services Center Coastal Observation Technology System - a project to further the development of integrated coastal ocean observing systems on a regular basis.
• OceanUS - National Office for Integrated and Sustained Ocean Observations coordinates development of an operational Integrated Ocean Observing System (IOOS)
