  1. SCCOOS Web Site Real-time Oil Spill Response Scenario

  2. Scenario • There was an oil spill near Rancho Palos Verdes at 33.7201 N, 118.3458 W today. • Use the wave conditions web page, meteorological conditions web page, surface current mapping web page, and Google Earth (if necessary) to answer the following questions about this oil spill.

  3. Questions • Do the weather and wave conditions allow us to send a response team to the site? • Where will the oil be in one hour? • If the conditions remain the same, where will the oil be in 12 hours?

  4. 1. Go to the wave conditions web page at http://www.sccoos.org/data/waves/?r=0 What is the swell height range for the area?

  5. What is the peak period (Tp) and peak direction (Dp) of the swell? *Answers will vary depending on conditions

  6. 2. Go to the Recent Meteorological Stations and Observations web page at http://www.sccoos.org/data/mets/

  7. What are the weather conditions in the area? • Air temperature • Air pressure • Wind speed • Wind direction • Wind gust • Humidity • Precipitation rate • When was this data collected? *Answers will vary depending on conditions

  8. 3. Based on the wave conditions and the weather conditions, can you send a response team to the site?

  9. 4. Go to the surface current mapping web page at http://www.sccoos.org/data/hfrnet/ 5. Go to View Full Page 6. Select 2 km 7. Disable the “Use 25 hr Averages” option 8. Locate the vector where the oil spill took place

  10. 9. Use the Progressive Vector Diagram Worksheet to record the measurements for 12 hours after the release time (assume constant current speed and direction). You don’t need to plote each point in Google Earth, but you may need to use Google Earth to determine which vector to move if the currents would move the oil more than 2 km (1.08 nm) in 12 hours. (1 kt= 1 nm/hr

  11. 10. You can also go to the Southern California Forecast Model web page to look at forecasts for wave conditions for upcoming days. You can click on any point on the map to get details about the forecast for that location.

  12. 11. Based on the information that you have gathered, how far will the oil travel one hour after the release time? If these conditions remain the same, how far will the oil travel 12 hours after the release time? *Answers will vary depending on conditions.
