The US National Oceanic and Atmospheric Administration (NOAA) National Geophysical Data Center (NGDC) and collocated World Data Center for Marine Geology and Geophysics, Boulder, CO, USA provides scientific data stewardship for many environmental datasets, including geological information derived from sea-floor samples. The essence of NGDCs stewardship philosophy is that data management practices must evolve and incorporate new technologies in order to keep data interoperable with complementary data streams and maintain their usefulness in a changing research environment. The Index to Marine and Lacustrine Geological Samples database exemplifies NGDCs evolutionary and collaborative approach to data management. The most recent version of the Index is a geospatially enabled relational database, providing data discovery and delivery via an interactive map on the Web. Geospatial databases and Internet mapping tools are an integral part of NGDCs current centre-wide systems architecture.
