To understand the effects of a major storm on an estuary, refer to Student Data Sheet 2 — Impact on an Estuary by anExtreme Weather Event: A Case Study. Study the graphs of precipitation and water quality for the Zeke’s Islandreporting station for August 1 to September 17, 1998. As you review the data, remember that Hurricane Bonniemade landfall on August 26.3a. What do you think caused the severe drop in salinity on August 26?3b. Why do you think the salinity of the water in the reserve continued to fall and then remain as such low levelsfor weeks after the storm event?3c. What was the change in water temperature caused by the storm?3d. How was the pH of the water in the estuary affected by the storm?3e. What caused the huge increase in turbidity around Zeke’s Island during the storm?3f. How long did it take for each of the water qualities to return to normal? Why do you think it took longer forsome factors to return to normal than others?Earth Science Module—Activity 413
