Notes

1. Review of prior ESIP Water Cluster Activities

Paul Houser, co-chair reviewed prior activities of the ESIP Federation Water Cluster. Those activities fell into 3 distinct areas:

development of the Earth Information Exchange (EIE) portal for water
contributions of ESIP partner data sets in response to the Puget Sound Initiative
technology contributions to GEO decision support initiatives (especially in the area of ontology development) (Will Pozzi)

2. Water Quality Exchange (WQX) General Update

Chuck Spooner, EPA Office of Water provided an overview of the Water Quality Exchange (WQX). He first provided background on the STORET data warehouse, an archive of state reported measurements accessible through an xml query. The WQX schema provides for a data and exchange format, which has now been adopted by USGS. EPA and USGS will be combining their query systems (< 1 year away from completion), with NOAA and Agricultural Research Service also interested. EPA's Office of Water is working with USGS and OGC to improve access to real-time data.

Other EPA Data Sources:

National Hydrography Dataset (NHD, NHD Plus) is an addressing system for facilities and sampling points
Watershed Boundary Data Set provides hydrologic unit codes (HUCs) for subsections of watersheds

Next Steps

EPAS's data system is now duplicated using USGS query techniques, with a possibility that a single query system will be used in the future
a master water quality portal is in development
methods of data analysis with automatic linking is a key priority for EPA data systems

Other Related Activities

Berkeley Water Center is working with Microsoft Research to make NWISS and STORET data available through SciScope (an Open Source tool). Will be adding Web 2.0 and 3.0 capabilities.
USGS Flow Network is working closely with NOAA
Environmental Information Exchange Network grant opportunity - closes Nov. 20 and available to states only

3. Presentation & Discussion of CUASHI Activities

Rick Hopper, CUASHI provided an overview of the Hydroseek (beta) search engine. Hydroseek is an ontology-aided search engine for finding scientific data on water quality and hydrology from approximately 1.9 million sites in the USA. The developers of Hydroseek sare seeking community input into the system, including metadata contributions from academia. The developers of Hydroseek are interested in improving the user search experience and community-built web services for the system.

It was noted that there are many tool building efforts underway and that Bruce Bargmeyer, Bill Sonntag and Chuck Spooner would work together across organizations to understand how such tools might be leveraged.
