Mid-ocean ridges (MOR) represent one of the most important geographic features on planet Earth. MORs are the locations where plates spread apart, they are the locations of most of the earths' volcanoes that harbor some of the most extreme life forms. These concepts attract much research, but mid-ocean ridges are still effectively not represented in the earth science class rooms. We began an internship at Scripps to develop a database for mid-ocean ridges as a resource for science and for education. Major research goals of this project include the development of an archival structure for data, images or any other arbitrary digital objects relating to MORs, and to compile a global data set for some of the most defining characteristics of every ridge segment. One of the challenges included the need of making MOR data useful to the scientist as well as the teacher in the class room. While this data base remains a long term project, we completed a series of first order steps that establish an archival structure and lay out the defining information for each ridge segment. To create this database we used existing maps of the age of the ocean floor (University of Sidney) and the MOR locations from the University of Texas database. We divided the global MOR system into segments through their end-point coordinates, using the mid-point lat/lon as a generic name and we digitized the area of the 11 Ma isochron. Each ridge segment was also characterized with the ocean it is in, and the names of the plates. This allowed us to create a database structure for MOR segments, similar to the seamount catalogue (http://earthref.org/databases/SC/main.htm). The data compiled allow us to determine the length of the ridges, spreading rates, the ocean crust production rates, and plate motion vectors for every ridge segment, ocean or the global ocean ridge system. The process of creating this data base introduced us to the excitement of MOR research, allowing us to create a resource that is equally useful for researchers as well as the members of the educational community.
