AB: Collection of field data on water and water quality is expensive. Vast quantities of data are collected by research, monitoring, and operational projects in North America, yet only monitoring data are routinely available. The Hydrologic Information System (HIS) project of the Consortium of Universities for the Advancement of Hydrologic Science, Inc (CUAHSI) has developed Water Data Services (WDS) using a services-oriented architecture to aid in the publication, discovery and access to time-series data collected at a fixed point. The underlying technological developments include WaterML, an XML-based language for transmission of time-series data, and WaterOneFlow, a set of web services that can provide access to data and metadata using standard web protocols. These technologies form the basis for an easy-to-use data publication system. WDS also includes a registration service for published web services and maintains a metadata catalogue of all services. An ontology of hydrologic concepts is included as part of this central service to enable variables to be mapped to a common set of concepts. A map-based discovery tool, Hydroseek (http://www.hydroseek.net/), has been developed using the ontology and metadata catalogue. CUAHSI has been working with US government agencies, such as the US Geological Survey, on providing access to their data holdings using web services and transmitting data using WaterML. Metadata from these agencies has been included in the central metadata catalogue, thereby enabling seamless access to both government and academic environmental data. This system could be expanded through the participation of other national governments, provinces, states and cities, as well as entities engaged in operational monitoring. All software is freely available.
