Tools & Services

IEDA Data Browser

Explore IEDA's global interdisciplinary data holdings through an interactive map interface. The IEDA Data Browser uses the GMRT Synthesis as a backdrop, and allows you to zoom to areas of interest and search across IEDA systems to discover interdisciplinary research data.

IEDA Investigator Support

MGDS and its partner system EarthChem together provide a suite of services in support of observational solid earth research in the Ocean, Earth, and Polar Sciences.

We make data management easy!

Antarctic Data Resources

The Antarctic & Southern Ocean Data Portal provides access to geoscience data from the Antarctic region, primarily acquired with the R/Vs Nathaniel B. Palmer and Laurence M. Gould.

Search for Antarctic Data

Visualization Tools

Use our desktop apps GeoMapApp and Virtual Ocean to explore, visualize and analyze your own data within the context of hundreds of other earth science data from around the world.

Carry the world in your pocket with our mobile app EarthObserver

GMRT MapTool

Create your own custom maps & grids! GMRT MapTool provides instant access to our GMRT Synthesis, a global multi-resolutional data set which includes seafloor bathymetry data to 100-m resolution where data are available.
