Presentation Transcript

  1. Coastlines of the Gulf of Mexico Louisiana, Alabama, Mississippi

  2. State Louisiana Mississippi Alabama Tidal Shoreline(mi) 7721 359 607 Shoreline Characteristics

  3. Island Morphology Barrier Island Chain -created after last glacial epoch (15,000yr ago) -decrease in sea level -increase in fluvial and marine sedimentation -microtidal (0-2m) -extensive tidal marsh habitat

  4. Coastal Features and Waterways Louisiana Rivers-Atchafalaya, Mississippi, Pearl Alabama Rivers-Alabama, Tom Brigbee, Mississippi Rivers-Pearl

  5. Recent Developments • Dramatic increases in nutrient loads -eutrophication -decreases in primary productivity -Wetland habitat in rapid decline -decrease in water quality -losses to commercial fishing

  6. Governmental Response • Total Maximum Daily Load (TMDL) -assessment of pollutants in major rivers -management plan to improve water quality Estuarine Reserve Program -modeling of individual systems -protection from development
