About MMI


To promote the exchange, integration and use of marine data through enhanced data publishing, discovery, documentation and accessibility.

Marine scientists face an opportunity and a challenge in the volume of data available from various ocean observing systems. The Marine Metadata Interoperability (MMI) Project can help make it easier for you to find, access, and use other data sets. If you create marine science data sets, MMI can help make your data easier to advertise, distribute, reuse, and combine with other data sets. Our goal is to promote collaborative research in the marine science domain, by simplifying the incredibly complex world of metadata into specific, straightforward guidance. MMI hopes to encourage scientists and data managers at all levels to apply good metadata practices from the start of a project, by providing the best advice and resources for data management. MMI maintains this website to foster communication and collaboration among its hundreds of members, and provides forums for discussion of diverse topics related to marine data management. 


The MMI project is guided by the MMI Steering Committee, advised by the Technical Advisory Panel. The Project Lead is John Graybeal of Marinexplore, the Technical Lead is Carlos Rueda of the Monterey Bay Aquarium Research Institute, and the  and site support is led by Felimon Gayanilo of the Harte Research Institute (HRI), Texas A&M University-Corpus Christi.

MMI participation comes from major marine science agencies and institutions around the world. We are a community-based organization, with strong participation from all areas of marine research.


The Marine Metadata Interoperability project is hosted by the Harte Research Institute (HRI), Texas A&M University-Corpus Christi. This support is led by Felimon Gayanilo, MMI Liaison

Major funding for starting the MMI project was provided by the National Science Foundation (NSF). We have received additional support from the following organizations:

  • University of California San Diego (UCSD), 
  • Southeastern University Research Association (SURA), 
  • Office of Naval Research (ONR), and 
  • NOAA Coastal Services Center (NOAA-CSC).
