Coastal Observations and Monitoring in South Bay
San DiegoGOALS

• A) Identify and track plumes from the South Bay
  Ocean Outfall (SBOO) (SS1, SS5, SS6, SS7, SS8)
• B) Characterize land based sources with focus on
  the Tijuana River (SS2, SS3, SS4, SS5, SS6, SS7,
  SS8)
• C) Identify the regional oceanographic conditions
  which lead to high fecal indicator bacteria (FIB)
  on the South Bay Beaches (SS1, SS2, SS3, SS4,
  SS5, SS6, SS7, SS8)
