Mark Otero Programmer/Analyst Coastal Observations and Monitoring in South Bay San Diego GOALS
• A) Identify and track plumes from the South Bay Ocean Outfall (SBOO) • B) Characterize land based sources with focus on the Tijuana River • C) Identify the regional oceanographic conditions which lead to high fecal indicator bacteria (FIB) on the South Bay Beaches: Requested Monitoring Activities 1. SBOO plume mapping 2. Tijuana River plume mapping 3. Boat survey-mapping of land based plume 4. Continuous flow rate and loading of the Tijuana River 5. Ocean moorings at key areas 6. Mapping of ocean currents using CODAR and improved data handling 7. The development of indicator studies to support source identification 8. Identification of spatial patterns Significant variability exists in the water quality of the region. SDCOOS goals to explain how the environment impacts this variability.

•Payload – 900 kHz sidescan sonar – 1200 kHz Acoustic Doppler Velocity Current Profiler (ADCP) – Conductivity, Temperature, Depth (CTD) – Optical Sensors for water clarity, chlorophyll, backscatter at 2 wavelengths – Compass –GPS – Iridium communications – Onboard navigation system Perspective view of Volume sampled
Plan view
• Vehicle operated to ‘mow the lawn’ at 3 depths: 25m, 17m, 10m in a box surrounding the SBOO. • Focused on lower third of southern wye which are where the operating diffusers are located. Sampling mission took approximately 6 hours. Conducted from 22’ Boston Whaler boat. Plan view of 20m depth data – plume appears to be southward Flowing during this time period. REMUS Missions at SBOO

Example OCSD – Huntington Beach Microbiological sampling a. Utilizes human-specific pathogens i. Prevotella/Bacteroides – bacteria found to be human specific ii. Pathogenic viruses (specific to humans) 1. Enteroviruses a. Different types can cause neurological or intestinal ailments, and respiratory problems b. Vector: person to person through contact with nasal secretions, saliva, stool from an infected person Symptoms: common cold – runny nose, cough, etc.; neurological and GI problems 2. Norwalk-like viruses a. Infects mostly GI tract b. Vector: infected by swallowing stool-contaminated food or water c. Symptoms: nausea, diarrhea, vomiting, stomach cramps d. Humans are the only known hosts 3. Adenoviruses a. Infects the membranes of the respiratory tract, eyes, intestines and urinary tract b. Symptoms: variety including respiratory, GI c.
