Abstract:
Dauphin Island Sea Lab and the Mobile Bay National Estuary Program have partnered with multiple agencies and organizations to provide real-time meteorological and hydrographic data from eight stations in and around Mobile bay, and along the Alabama gulf coast. Near real-time data are available in a user-friendly format at www.mymobilebay.com. Data are being transmitted to Gulf of Mexico Ocean Observing Systems (GCOOS) and the National Data Buoy Center (NDBC) within half an hour of data collection. Informative pop-ups describe each parameter and graphs of each may be displayed for the visitor to the website. Researchers may download the data in a spreadsheet format for further analysis.
Purpose:
The value of coastal observing systems is recognized by the U.S. Congress, the National Ocean Partnership Program, the Environmental Protection Agency, and the National Ocean and Atmospheric Administration. Recent reports by the Pew Oceans Commission and U.S. Commission on Ocean Policy have decried the lack of information from near coastal waters on which to base management decisions and recommended monitoring programs linked to strong research. Reasons for continuous, real-time observations of meteorological and hydrographic parameters include (1) continuous characterization of spatial and temporal patterns of change in water quality, (2) development of a permanent record of significant and human caused changes in environmental indicators over time, and (3) support for research activities through the availability of consistent, scientifically valid data. An additional benefit of real-time observation is the potential for the public to track and learn about water quality conditions. Many coastal dwellers are uninformed about conditions in nearby estuaries because they do not have access to current information about parameters such as water temperature, salinity, dissolved oxygen levels and water level and they may fail to appreciate the complexity of interactions in estuarine ecosystems.

Data_Quality_Information:
Logical_Consistency_Report:
We are conducting range checking on all parameters displayed on the website. From the Environmental Monitoring dataset, a user can obtain valid information about atmosphere and ocean data in the Mobile Bay area since 2003.
Completeness_Report:
We provide near real time environmental monitoring data on the website, 24 hours a day, 7 days a week. There have been interruptions in the transmission of data. Occasionally stations were damaged by hurricanes, communications were interrupted or sensors failed. For those time periods, data were not written to the data base. When a data string comes in and one or more parameters are missing, then the missing data is flagged -9. Please refer to http://cf.disl.org/mondata/dataperiod.cfm for data availability.

Process_Description:
The range checking program was developed in house. Data that fail the range check are automatically flagged 2 (questionable/suspect), data that pass the range check are flagged 3 (good). Please refer to http://cf.disl.org/mondata/rangecri.cfm for range checking criteria.
