Description
The Seamount Catalog carries a series of key products that will serve the SBN network, including access to a wide range of map products that range from simple downloadable bathymetric maps to the XYZ NetCDF grids and the original data files (multibeam, sidescan) that may be recombined with other data sets to upgrade or re-plot the maps, according to the users own needs and expertise. The Seamount Catalog features an easy-to-use search interface that displays available data for download and some vital statistics for more than 1800 seamounts, such as summit depth, seamount length/width and volume, shape, elongation, age, ocean floor depth and age, multibeam coverage, etc.

Description
The EarthRef.org website originally has been developed as the host website for GERM (the Geochemical Earth Reference Model initiative), but it is now a very substantial website for a wide range of Earth science data that spans from geochemistry to paleomagnetism to geochronology and more. A variety of EarthRef.org tools and databases are immediately available to its users: The EarthRef Address Book is a much used directory for Earth scientists address information (~2,000 registered users) that is frequently visited by users using web search engines such as Google. The Earthref Reference Database includes a very substantial number (~95,000) of publications, archived with complete reference information, abstracts and, in many cases, Microsoft Excel files of tables and appendices. Finally, the EarthRef Digital Archive is a fully functional database that archives any digital object with a critical number of metadata to make it efficiently searchable by researchers, teachers and students. You can upload your own data files in this archive. On top of these common tools, the EarthRef.org Web Portal functions as the umbrella web site for the GERM, MagIC, SBN and ERESE initiatives.

Description
Henry Seamount is a 660-m-high circular structure that rises from 3700 m deep seafloor southeast of El Hierro, close to the present location of the Canary hotspot. Because of its morphology and thick sediment coverage the seamount is interpreted as a comparatively old and passive volcano. A dredging campaign in 2005, however, yielded some volcanic rocks, massive barite and also well-preserved shells of vesicomyid clams that are indicative of active fluid flow. It appears that the seamount is or was recently discharging warm fluid, the driving force being either volcanic activity from Henry Seamount itself or heating of the underlying crust by the nearby hotspot.
