Sharing SRP Water Sample Data Using CUAHSI HIS Infrastructure

1. Sharing SRP Water Sample Data Using CUAHSI HIS Infrastructure Ilya Zaslavsky, Thomas Whitenack, Keith Pezzoli, Hiram Sarabia University of California at San Diego, San Diego, CA, USA HIS Central Publishing SRP water sample data About CUAHSI Adding a water data service to the integrated metadata catalog The Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) is an organization representing 120+ universities in the US and 11 international affiliates. As • CUAHSI HIS supports data publication workflow for hydrologic observations. The steps include: • Loading data into ODM instance and configuring a Generic ODM web service providing access to the data (typical for relatively small academic projects) OR • Configuring a custom WaterML-compliant web service and assembling a source metadata catalog (typical for large remote repositories) • Registering the new water data service at a local HIS Server (to be accessible via DASH, Data Access System for Hydrology), AND/OR • Registering the service at the HIS Central, a web application for managing and exploring WaterML-compliant services. • By indexing both government and academic water data services, HISCentral provides a gateway to the largest collection of water observations in the nation. • Once a new water data service is registered, tested and described at HISCentral, an HISCentral’s harvester retrieves site and variable metadata, and the data series information. part of its mission, CUAHSI supports the development of cyberinfrastructure for the hydrologic sciences. The CUAHSI HIS (Hydrologic Information System) project is a multi-year multi-institution effort focused on consistent management and integration of observational data available from several federal agencies (USGS, EPA, USDA, NOAA, etc.) as well as published by academic investigators. Register service CUAHSI member universities in the US UCSD Upload icons, add metadata Service oriented architecture for sharing water data Rainfall & Snow CUAHSI HIS develops service-oriented architecture for hydrologic research and education, to enable publication, discovery, retrieval, analysis and integration of hydrologic data. The project team has defined a common information model for organizing hydrologic observation data, designed a common exchange protocol (Water Markup Language), created a collection of SOAP web services (WaterOneFlow services) that provide uniform access to different federal, state and local hydrologic data repositories, and developed mechanisms for ontology-based data registration and discovery. Soil water Test Service UA Meteorology Water quantity and quality Remote sensing End-to-end three-tier solution: from publication and registration to discovery and analysis of hydrologic observation data Service is harvested Tag variables with ontology concepts The next step is tagging the harvested variables using CUAHSI ontology concepts, and making the new water data service appear in Hydroseek, a web application for ontology-based and map-based search and retrieval of hydrologic data from multiple networks. The service may be also shown in DASH: Data Access System for Hydrology Data is available in Hydroseek and in DASH Deployment UCSD This system is implemented as a collection of HIS Servers deployed at NSF-supported Hydrologic Observatory test beds across the nation. Several HIS Server are deployed at other partner universities and agencies, and internationally. UA This pilot implementation integrates water sample data collected by SRP programs at University of California San Diego and University of Arizona. The UCSD Renew-SD project studies Superfund toxicants in the highly urbanized (upwards of 90% developed) Chollas Creek Watershed in San Diego, CA. Dry-weather urban runoff samples are examined with both conventional analytical chemistry methods (ICP/GCMS) and emerging SRP molecular bioassays (P450 HRGS). Findings show that while dry-weather urban loading of toxicants to the Chollas Creek Watershed and San Diego Bay are comparatively low with respect to wet weather inputs, toxicants like lead, cadmium and PAHs are present in varying concentrations in dry weather urban runoff. The UA study focused on determining arsenic exposure via drinking water and characterizing urinary arsenic excretion among adults, and later in children, in four towns of Yaqui Valley, Sonora, Mexico.

Extending hydrologic controlled vocabularies and the parameter ontology is necessary for making SRP data discoverable in Hydroseek.
