Koppers, Hubert Staudigel, and Rupert Minnett , Volume 23, Number 1, a quarterly journal of The 23, NumberOceanography 1, a quarterly Society. , Volume Seamount research, more often than not, is carried out by highly specialized science teams with narrowly focused science objec- tives. As a result, different seamount science disciplines often do not collaborate or are not even aware of each other. However, it is obvious that interdisciplinary collaboration is the most successful approach to help understand the integrated chemical, phys- ical, and biological systems at seamounts. The Seamount Biogeoscience Network (SBN) was founded to promote the neces- sary cooperation through workshops, publi- © 2010 by The Oceanography Society. All rights reserved.

Among such data, bathymetric maps are the most fundamental to all disciplines. The Seamount Catalog (see http:// earthref.org/SBN) is a hub for a variety of map-related data and user-contributed files. It functions as an online digital archive for bathymetric maps GEBCO (General Bathymetric Chart of the Ocean) gazetteer of seamounts that can be viewed and downloaded in various data are included in the database in order to provide informa- file formats. Additionally, this catalog contains morphological tion on the history, discovery, and names of the seamounts. data characterizing seamounts, sample information, and Data files for each seamount include a map made from the related grid and multibeam data files, including relevant user- multibeam data only, a map made from Smith and Sandwell’s contributed data. Educational materials about seamounts are (1997) predicted bathymetry, a merged map incorporating included in the interlinked collection of Enduring Resources both data sets, and a map showing the discrepancy between for Earth Science Education (ERESE), including, for example, the two data sets. Currently, the Seamount Catalog contains a lesson plan on hotspot volcanism for high school students the maps and corresponding raw and processed data from (http://earthref.org/ERESE/lessons/hotspots/2006/).
