Title | Dissolved oil plume from mixed layer source (decaying) |
| Description | The simulated concentration (in parts per billion) of dissolved oil in the ocean mixed layer (near the sea surface). The simulated ocean currents used here are plausible but should not agree in detail with the observed currents. The source of oil is steady between April 20th and July 15th but the plume wavers back and forth with the changing ocean currents. The initial position of the loop current can affect the exact location of the dissolved oil plumes, but will not substantially alter the confinement of the significant concentrations to the Northern Gulf of Mexico, provided that the microbial oxidation is taken into account. | |

Title |
Dissolved oil plume from mixed layer source (non-decaying) |
| Description | In contrast to the first animation, animation 2 shows what happens if microbial decay is omitted (as in some previous studies); the strong surface currents can spread the plume of dissolved oil throughout the Gulf of Mexico and as far as the Florida Straits and beyond. This extensive spreading of dissolved oil is not what has been observed and we do not believe that this animation is representative of actual events. | |

Title |
Oxygen draw-down due to the deep plume |
| Description | The percentage draw down of dissolved oxygen for a 300 m thick deep plume (as a percentage of climatological levels at 1,000-1,300 m depth). The regions of significant oxygen depletion remain confined to the source region. If the actual plume were much thicker, both the hydrocarbon concentration and oxygen draw down would be proportionately smaller due to dilution. | |

Ocean Surface Temperature
|
Sea surface temperature (SST) simulation from GFDL's high resolution coupled atmosphere-ocean model. As the animation focuses on various locations of the world ocean we see the major current systems eg. the Agulhas current, Brazil current, Gulf Stream, Pacific Equatorial current, Kuroshio current. The small scale eddy structure is resolved and evident. |

The animation focuses on the Loop Current as it flows into the Gulf Stream (a major surface current). Note the black colors indicate the warmest ocean surface temperatures and and light blues indicate the coolest temperatures. Sea surface temperature (SST) simulation from the Geophysical Fluid Dynamics Laboratory's (GFDL) high resolution coupled atmosphere-ocean model. |

Ocean Surface Salinity

This is a simulation of the Arctic Ocean Surface Salinity
from GFDL's high resolution coupled model. One can see the seasonal cycle
of summertime freshening from sea ice melt as well as the salty water entering
from the North Atlantic current. |
