NOAA NGDC Bathymetry Data Viewer (powered by ArcGIS 10 Server)

Provides discovery and delivery of all the NOAA and non-NOAA bathymetric data and derived digital elevation models archived and delivered by NGDC. The viewer includes NOS Hydrographic Survey data, non-hydrographic NOAA bathymetric data, bathymetric data from the U.S. academic fleet, and international bathymetric track line data. It is based on ArcGIS Server 10 and is significantly faster and more responsive than the old individual map servers. You can select from several different backgrounds and each survey is color coded by year (see Legend). When you select an area, an "additional information box" launches with the survey name, survey attributes, and a link to acquire the data. Upcoming developments include the ability to switch to an Arctic map projection, the addition of advanced search and filter tools, and seamless scrolling around the world.
