A Coastal Water Quality Metadata Databasefor the Southeast U.S.A.

University of Georgia
Background NPS needed information on water quality monitoring in SE USA
Developing SE Coast Network monitoring program Avoid duplication of effort Identify comparable data to leverage Discover data gaps for future expansion Information proved very difficult for NPS to obtain
GCRC funded to identify long-term monitoring activities Workshop to gather input, info on regional activities Developed database of long-term monitoring program metadata Developed interactive web applications, services for querying database Phase 1 completed in 2009
GCRC funded in 2010 to extend scope, functionality (Phase 2)
Rationale
Numerous agencies and institutions collecting water quality data
Information highly dispersed Large federal databases (USGS, NOAA, EPA) Program/project web pages (NERR, LTER, USFS, NPS, SAML, ...) State/municipal web pages Offline sources (reports, brochures)
Information diverse in scope, format, accessibility Web pages, text files, XML, maps/visualizations Online sources have radically-different interfaces, export capabilities
Unified database needed to facilitate discovery
Monitoring Station Search Examples
Project Scope and Goals Targeted information
Programs monitoring water quality (and related measurements) Sponsoring organization information Description (mission, goals, policies) Points of contact (web site, names, email) Time period
Monitoring locations/stations Geographic location (state, county, HUC, latitude/longitude) Parameters measured Time period Web links for information and data downloads
Geographic Scope Phase 1: coastal zone of NC, SC, GA, East FL Phase 2: South Atlantic Landscape Conservation Cooperative (SALCC)
Geographic Coverage
Database Design Process Designed relational database to store content
Used SQL Server 2000/2005 Support for relevant metadata content standards (EDSC) Support for adding new metadata fields, varying completeness Support for varying granularity in searches (thematic & geospatial)
Developed “middleware” for connecting to database Standard queries (views) to abstract structure, simplify querying Stored procedures for updates and programmatic queries XML middleware for Google Maps, web services (SQLXML)
Developed user interfaces for update/query MS Access forms for GCRC staff Web portal for public access (IIS/Active Server Pages)
Hierarchical design with strong referential integrity Organizations Monitoring Programs Monitoring Stations Measured Parameters
Flexible content model for Organization/Program metadata Fixed fields for critical content
(name, acronym, web URL, ...) Controlled vocabularies of optional
fields for descriptive metadata Supports wide range of detail based
on reporting practices
Data Model
Data Model
Monitoring station metadata Site name, description Lat/Lon State/County/location 8-digit HUC Probabilistic or long-term site Dates of operation Data download/request URL
Measurement parameters Linked to stations or programs Linked to USGS NWIS STORET codes Parameter groups for multiple levels of
detail (nutrients > nitrogen > ammonium)
Populating the Database
List of candidate organizations/programs from NPS, workshop input and local knowledge
GCRC staff entered organization and program info from web
Monitoring locations, dates, parameters entered multiple ways Mined from program databases if online, queryable
Federal: USGS NWIS, NOAA NWS (NCDC), ... National Programs: NERR CDMO, LTER, ...
Requested in spreadsheet form if not online NPS, state agencies, municipalities, ...
Program reps asked to check entries

Database Statistics (Apr 2011)
Organizations: 22
Monitoring Programs: 42
Monitoring Locations: 44,057
Parameters Measured: 2266
Location-Parameter Records: 764,887
Accessing the Database Prototype web portal: http://www.gcrc.uga.edu/wqmeta/ Browseable lists of organizations, programs with links to info Search for monitoring locations by multiple criteria
Program name, site name, site type Parameter name (or category, tag, ...) Date range Hydrologic Unit (8-digit HUC) Geographic bounding box (with map input)
Multiple output formats Paged web table with links to station details Spreadsheet (CSV text) Google Earth KML with informational balloons, time-span tags XML text (web service)

Ongoing Work Continue adding programs, stations, parameters
US EPA STORET/WQX (?) NADP, NPS, USFS
Enhance web portal appearance and usability Organization and program metadata search/retrieval Geographic placename search (state, county, location) Additional parameter search options (USGS NWIS code, ...)
Coordinate with other regional efforts

Conclusions
Extensive effort is required to acquire comparable information about water quality monitoring programs
Providing unified access to monitoring metadata on a web portal, with links to program contacts and data downloads, is a valuable service for researchers, resource managers
