This is an annotated still shot of a simulation video for the 1,000- to 1,300-meter depth interval of oxygen anomalies compared with the presence or absence of a contemporaneous oxygen anomaly observed during the response efforts. Solid green squares indicate concurrence between the model and observations, whereas solid red squares indicate disagreement. The red concentric ring around each solid red square indicates the minimum distance to achieve concurrence. The location of the Macondo well is shown by a black circle. A running tally of concurrence/disagreement is shown at the top left.
