Ridge 2000 Data Portal: Project Documents

About the Ridge 2000 Data Portal

The Ridge 2000 Data Portal was established in fall 2003 in response to a program call for a dedicated data system to facilitate open and timely exchange of data in support of the interdisciplinary science goals of the program. The Data Portal has been built with the primary goal of providing full cataloging, open access, and long-term preservation of data collected during R2K programs. The backbone of the system is an expedition metadata catalog, which provides information on field programs (who, what, when and where), inventories of sensor data and samples, relevant metadata and the links to the primary data files which reside either within the Data Portal or at distributed repositories. Processed and derived data products are also served as contributed. The system is designed to leverage all relevant existing data resources and provides a framework for a broader distributed data system.

Available Data

Cruise and data acquisition information, navigation and the majority of shipboard field data from all R2K-funded cruises conducted at all Integrated Study Sites are available through the Data Portal. Partial to complete cruise information, navigation, and field data from ~100 cruises, which pre-date the R2K program can also be accessed. Data submitted from these cruises include bathymetry, sidescan, seismic reflection data, earthquake catalogs, water column MAPR, CTD, and ADCP data, fluid chemistry data, temperature probe data, biological species lists, Alvin and Jason navigation and remote access to bottom photography, and towed camera system navigation and images, rock, fluid, sediment and biological sampling information as well as instrument deployment and recovery information. As the R2K program moves from the data acquisition phase to synthesis and integration, more processed and derived data products are now discoverable through the Data Portal. Examples include bathymetric grids, genetic sequences, and geochemical data sets served by PetDB.

Data Access

To accommodate the different needs of scientists for accessing data, two data access tools have been developed; a text-based search tool (browser based) for researchers wanting, for example, to find specific data sets of interest or all data from a cruise or region; and a client-side graphical application, GeoMapApp, to visualize and explore data holdings in a map interface. For each of the ISS, users can visualize available sonar datasets (multi-resolution multibeam, side-scan), Alvin and Jason 2 tracks and near bottom images, as well as samples and stations from all R2K funded programs. The Data Portal is adopting standards compliant web services to serve data holdings in order to provide users with greater flexibility to use the data visualization and analysis tool of their choice (e.g. ArcGIS, NASA World Wind, Google Earth). The Ridge 2000 Data Portal has been developed in parallel with the MARGINS Data Portal, as part of the Marine Geoscience Data System. Tools and services for accessing data are common across the system.

Right panel: KML files for accessing data using Google Earth are also available through the Data Portal. In the example shown, a photomosaic from the Kilo Moana Vent Field collected with Jason 2 by Chuck Fisher during TUIM07MV is overlain on high resolution bathymetry from TUIM05MV.
