Question

What was the rate of marsh loss in the area studied before and after the Deepwater Horizon oil spill? (Include the appropriate units.) What does this finding suggest? Are there any other factors that could contribute to the difference in rates?

Answer 1

Before: 0.8 meters.

After: 1.7 meters.

This finding suggests the oil spill has played a meaningful role in shore loss.

Step-by-step explanation:

Before the spill, the marshes under study had been retreating an average of 0.8 meters per year. After the spill, the rate increased to approximately 1.7 meters per year on average.
