Abstract

Earth system sciences is being challenged by the intellectual and the societal requirements of how to quantify the spatial patterns and temporal dynamics of changes in the atmosphere, landscape, and seascape, including human resources management. There are multiple issues in how to do this. The first is establishing the multi-disciplinary basis of how to systematically organize the required geophysical elements, from the very slow geological process forming the basic template to the very fast moving event-driven processes brought on by an individual rainstorm. The second is how to mobilize, access, see, and interact with the very disparate sources of information required. The third problem, perhaps the most difficult, is how to get the disparate disciplinary and management experts to constructively interact. These requirements drove the process for establishing the PRISM "Virtual Puget Sound." The basic construct is recognizing the inherent time and space attributes of the landscape, and then constructing an informatics environment that will allow the respective elements to be brought together in a collaboratory. Central to the enterprise is the use of an XML-enabled DataStream, to mobilize data from archives to models to visualizations. Outcomes are addressing such regional issues and daily stream flow, seasonal water supply and demand, low oxygen in Hood Canal, and sewage treatment plan siting. This model is being extended, as an Earth System Module, elsewhere in the world, from the Amazon to the Mekong.
