Virtual Ocean

Virtual Ocean is a three-dimensional visualization tool that combines the GeoMapApp tool suite with the NASA World Wind Earth browser, allowing users to explore geoscience data sets on a virtual globe. Virtual Ocean is a Java™ webstart application that will run on any computer platform with a Java Runtime Environment.

Virtual Ocean allows users to visually view any part of Earth by rotating around Earth or by using zoom features. Users can also load ASCII comma-delimited or tab-delimited files with spatial locations of latitude and longitude.

Data Sources

Global Digital Elevation Model (DEM)

Virtual Ocean provides a global, multi-resolution digital elevation model (DEM). The DEM includes high resolution (~100 m node spacing) topography from multi-beam data for ocean areas and Shuttle Radar Topography Mission (SRTM) data over land.

Marine Geoscience Data System (MGDS)

The Marine Geoscience Data Program (MGDS) embedded within Virtual Ocean allows for access to numerous data portals, including Global Multi-Resolution Topography Synthesis and Seismic Reflection Field Data.

International Ocean Drilling Program (IODP)

The Integrated Ocean Drilling Program (IODP), an international scientific research program supported by twenty-four countries, advances scientific understanding of Earth by monitoring, drilling, sampling, and analyzing subseafloor environments.


Janus is the Integrated Ocean Drilling Program's Oracle relational database. The database contains 450 tables of International Ocean Drilling Program's marine geoscience data, which are collected onboard the drillship JOIDES Resolution. The database includes paleontological, lithostratigraphic, chemical, physical, sedimentological, and geophysical data for ocean sediments and hard rocks.
