Marshes And Sea Level Rise

Nathaniel Weston, a marine scientist at Villanova University, studies the impact of climate change and sea level rise on salt and freshwater marshes. Supported by the National Science Foundation, his research focuses on how these changes affect marsh ecosystems. Rising sea levels and reduced freshwater flow can lead to saltwater intrusion into freshwater marshes, impacting local flora and fauna. The Intergovernmental Panel on Climate Change predicts significant sea level rise by 2100. Weston's team conducts fieldwork to measure marsh elevation and sedimentation rates, while lab work helps understand landscape changes. The research highlights the increased vulnerability of coastal areas to extreme weather events and underscores the importance of healthy marshes as natural buffers and nurseries.

What is the primary focus of Nathaniel Weston's research?

• Studying marine life in the ocean

• Investigating the impact of climate change on marsh ecosystems

• Developing new agricultural techniques

• Exploring the depths of the Delaware River

How does sea level rise affect freshwater marshes?

• It has no significant impact

• It causes saltwater to move into freshwater areas

• It decreases the temperature of the water

• It increases the amount of freshwater available

What tool is used to measure the elevation of the marsh surface?

• A thermometer

• A barometer

• A hygrometer

• A surface elevation table

Why are healthy marshes important during storms?

• They have no effect on storms

• They attract more storms

• They act as natural buffers

• They increase the speed of storm surges

What is one potential consequence of more intense storms and hurricanes?

• Decreased sea levels

• Increased vulnerability of coastal populations

• More freshwater in marshes

• Less property damage
