- Title:
- Mobile - Tensaw Delta Hydrological Modifications Impact Study
- Description:
- Abstract:
- Continuous monitoring data that includes water temperature, conductivity, salinity, water level, dissolved oxygen, turbidity, pressure, and resistivity collected on both the north and south sides of the causeway in the Mobile-Tensaw Delta.
- Purpose:
- Within the Delta proper, a large dike-like causeway built in the late 1920s has severed a number of once open bays from immediate contact with the waters of the Gulf of Mexico. By altering tidal exchange and volume of flow, this hydrological modification may have altered the ecological function and biodiversity of the Mobile-Tensaw Delta as well. To address this question, the Mobile Bay National Estuary Program funded a one year study designed to collect preliminary data assessing causeway impacts on the ecology of the lower Mobile-Tensaw Delta.
