GeoMapApp

GeoMapApp is a global topography and bathymetry database that is integrated with an application to explore and edit the data. The visualization tool was developed as part of the Marine Geoscience Data System at the Lamont-Doherty Earth Observatory of Columbia University. The application runs on a variety of operating systems using the Java Runtime Environment.

GeoMapApp relies on the internet to access and utilize data for physical oceanography, paleoclimates, geochemistry, geology, seabed sediment and rock compositions, ocean crust age, spreading rates, bathymetry, and sediment thickness. Users can select and view seismic reflection, gravity, magnetic and topographic profiles from tens of millions of kilometers of ocean surveys dating back to the 1960s. There are dedicated interfaces to explore the results of 40 years of ocean floor drilling, earthquake locations, magnitudes and epicenter depths, and seabed photographs from submersibles, remotely operated vehicles and towed camera sleds. Tabular datasets are selectable with lasso tools and can be manipulated in interactive graphs. Grids and tables can also be imported from other file systems and websites.

Global Multi-Resolution Topography

The Global Multi-Resolution Topography (GMRT) synthesis is a continuously-updated compilation of seafloor topography derived from multibeam bathymetry data. It is maintained as a multi-resolution gridded digital elevation model of seafloor bathymetry to ~100 meters spatial resolution, and is merged with ~100 meters resolution land topography data from the Shuttle Radar Topography Mission (SRTM). In the oceans, multibeam data are merged with lower-resolution compilations including satellite predicted bathymetry, the International Bathymetric Chart of the Arctic Ocean, and the SCAR Subglacial Topographic Model of the Antarctic.

NSF Ridge 2000 data from the East Pacific Rise

Ridge 2000 is a multidisciplinary science research program focused on integrated geological and biological studies of the Earth-encircling oceanic spreading center system. Ridge 2000 data from the East Pacific Rise is used in this chapter, including locations of hydrothermal vents and high-resolution (5 m) bathymetry grids.

Data Provider

The Ridge 2000 data portal is sponsored by the National Science Foundation and hosted by the Marine Geoscience Data System at Lamont Doherty Earth Observatory of Columbia University
