Integrating and Visualizing Sea Ice Charts and Cruise Tracks using Linked Open Data and Open Source Tools


The Semantic Sea Ice Interoperability Initiative (SSIII) is an NSF-funded research project aimed at making sea ice data more useful to more people using semantic technologies, and includes domain and science data experts at the National Snow and Ice Data Center (NSIDC) and knowledge representation experts from Rensselaer Polytechnic Institute (RPI). SSIII has developed ontologies for modeling sea ice charts as open linked data, making those data available on the web to a wider audience of researchers using web-standard representation and query languages. We will demonstrate a prototype web interface that incorporates the linked data published by SSIII with cruise tracks and dataset metadata published by Woods Hole Oceanographic Institute's Biological and Chemical Oceanography Data Management Office (BCO-DMO). We will show how one can use this interface to (1) determine sea ice concentration, form, and stage of development in the region around a particular cruise during a specified time frame; (2) animate sea ice changes during a given time frame; and (3) highlight links to relevant datasets based on user selections and metadata present in linked data repositories. This interface is built on an open source software stack and may serve as an exemplar to other projects looking to model and integrate geospatial and temporal datasets distributed across the Web.
