The seismic reflection method, developed primarily by the oil exploration industry, is arguably geophysics' most versatile
and powerful tool for mapping the earth's interior. It has been increasingly applied over the past 25 years to a wide variety
of studies of the earth's crust and upper mantle by a diverse mixture of individual, institutional, national and
international programs. The results from these efforts have revolutionized, and continue to advance, our understanding of
the Earth's lithosphere. Yet until now there has been no central guide to the results of those efforts nor their continuing
status. ELLIPSE is an effort to develop a comprehensive, global, dynamic catalog of deep seismic reflection surveys past and
present. This catalog, in the form of a GIS database with user-friendly cartographic interface, serves as an internet portal
to a metalibrary of deep reflection data that is derived from the physical libraries that are now globally dispersed and
heterogeneously maintained. Core components of this metalibrary, and a proposed template for organizing comparable physical
collections worldwide, are COCORP (US), INDEPTH (Tibet) and URSEIS (Russia) datasets currently archived at Cornell. These
datasets are not only of considerable continuing scientific value in their own right, they typify the range of data
characteristics of the larger global collection. ELLIPSE provides the final processed data, but access to the "raw" data and
the metadata needed to reprocess, field photos and published interpretations. This multidimensional electronic publication
will aid not only the serious researcher who may want to reprocess the original datasets, but the non-specialist who finds
the final product useful in synthesis with other data, the classroom instructor who needs an easily comprehensive form of the
results for the general student, or the earth science student who simply wants to browse the earth's interior for
inspiration.
