1 Bight 03 Water Quality Plume Effects Chapter

2 Chapter Outline Plume Effects: suspended load; nutrients; bacteria; toxicity Where do constituents go? –Remote sensing Discrete -> Satellite data -> Salinity -> Estimates -> Management decisions (???) –How many tons SiO4 enter system during storm? –Provide social and regulatory perspective –Link to other studies What is their duration? –Bacteria well documented –Nutrients convert to phytoplankton = couple –Site specific investigations

3 Chapter Outline Lessons learned –Self evaluation –What worked; what didn’t –Critique calculations used –Why was WQ good?
