Abstract

AbstractNational Oceanic and Atmospheric Administration's (NOAA's) National Geophysical Data Center (NGDC) ensures the security and widespread availability of scientific marine geophysical data through long-term stewardship. Marine geophysical data extend from the water surface, through the water column, to the seafloor and even the geology beneath. In addition to ensuring the quality, integrity, and accessibility of these data, NGDC develops derived products such as precise representations of Earth's magnetic field and digital elevation models for coastal and marine areas. NOAA and our partners expend significant resources to survey our coasts and oceans. In order to maximize the return on this investment, the data must be easily discoverable and readily accessible by numerous users and applications now and well into the future. To meet these goals, NGDC is drawing on a variety of software technologies and is strictly adhering to international data standards. The result is a geospatial framework built on spatially enabled databases, standard-based Web services, and International Standards Organization (ISO) metadata. NGDC's suite of tools and services delivers over 40 TB of marine geophysical data each year to a wide range of customers. By making the data more accessible to both human and machine clients, NGDC extends the use of, and therefore the value of, these data. The result is environmental information that enables informed decisions.
