Figure 1: We’ve starting using some of the Products from the Louisiana Office of Homeland Security and Emergency Preparedness. http://gohsep.la.gov/oilspill.aspx and click on the “Click Here for Google Earth Layer (kmz file).” The above figure shows the analysis showing the pbserve slick locations for June 23. The magenta lines are the deep currents from the previous blog posting.
Figure 2. Here we have the oil slick forecast from Louisiana for today, June 25. We have excellent HF Radar coverage of the northern end of the slick. In the HF Radar fields we see strong currents to the north east on the outer shelf along the shelf break. Shoreward and west of this jet we see a counterclockwise circulation with currents to the west on the inner shelf off the coast of Alabama and Mississippi. To the east of this jet we see the opposite rotation, a weaker clockwise cell.
Figure 3: We also have our students working on producing new KMZ’s for community use. Here Mike just gave me a new kmz plotting the SABGOM (South Atlantic Bight, Gulf of Mexico) model from Ruoying He at North Carolina State University. This first google earth map from SABGOM shows the sea surface temperature. We’ll keep putting together the current vectors and add the kmz to the Deepwater Horizon portal resource list. http://rucool.marine.rutgers.edu/deepwater/
In this zoom out to show the full model domain, we see the Horizon Marine drifter that left the Gulf of Mexico heading north in the Gulf Stream.
