Goals and Learning Outcomes
On completing this module, students are expected to be able to:
- describe the processes that cause sea level to rise and fall;
- explain the evidence for sea level change in the geologic record and over the last century;
- project sea level rise in coming decades and beyond and their impact on coastal communities;
- propose strategies to cope with rising seas in communities that are most threatened by sea level rise.
After completing this module, students should be able to answer the following questions:
- How much is sea level forecasted to rise in 2100?
- What are the processes that are causing modern sea level rise and what is the relative role of each?
- How much would sea level rise if all of the ice on Greenland and Antarctica were to melt?
- What is the current rate of sea level rise?
- What instruments are used to measure modern sea level rise?
- What faunas can be used to reconstruct ancient (but fairly recent) sea levels?
- When in the last 25 thousand years were the fastest rates of sea level rise?
- What are some of the processes that are causing relative sea level change in the region around New Orleans, and how much are some parts of the city subsiding?
- What do the terms transgression, regression, and sequence refer to and how do they fit into the concept of relative sea level change?
- What is reflection seismology and how does it help determine ancient sea level?
- Why was sea level so high in the Cretaceous and Eocene?
- What is storm surge, and why did it do so much damage during Katrina?
- What strategies are being used to prevent flooding in the next Katrina?
- What strategies are being used to prevent flooding on the Outer Banks, Netherlands, and Venice?
- What is the future of sea level rise in Bangladesh, Pacific Islands, and the Torres Straits?
