AB: Web-based digital databases are being developed by a number of academic and governmental groups to improve the ability of researchers and students to access geoscience data in a convenient and user-friendly manner. With funding from the U.S. National Science Foundation, the Marine Geoscience Data System (MGDS) (http://www.marine-geo.org/) serves as the data portal for the NSF MARGINS program, providing free public access and preservation to a wide variety of marine and terrestrial data collected during MARGINS projects. The broad suite of integrated database holdings includes rock, fluid, biology and sediment samples information and station details, multibeam bathymetry and underway geophysical data, multi-channel seismics, and water column data. Seamless links point to external repositories for geodetic data (UNAVCO), and land seismic campaign data (IRIS). GeoMapApp (http://www.geomapapp.org/), an MGDS data visualization tool, supports map-based dynamic exploration of data using a multi-resolution global digital elevation model. Built-in land and marine data sets include EarthChem geochemistry, plate boundaries, DSDP/ODP core logs, earthquake events, seafloor photos, and submersible dive tracks. Users can also access land and marine data sets through OGC-compliant Web Services provided by external repositories including PetDB, UNAVCO, IRIS and NGDC. Users can generate custom maps and grids and import their own data sets and grids. A set of short, video-style online tutorials familiarises users step-by-step with GeoMapApp functionality (http://www.geomapapp.org/tutorials/). GeoMapApp is used in a number of undergraduate mini-lessons created during the MARGINS EPO workshop (April, 2007) and is the basis for two education modules hosted at SERC-Carlton (http://www.marine- geo.org/Education.html). MGDS data portal resources make available a wide variety of real scientific data from large NSF-supported research programs. Examples of accessing and manipulating a range of data sets from the MARGINS, DSDP/ODP and Ridge 2000 programs will be shown.
