I have 2 quick Environmental Biology lab worksheets due next Saturday. I attached the documents.

Sea Level Rise Lab

Analyzing Sea Level Rise

Part 1

This has been adapted from educational materials available from nasa.org.

Use the satellite data graphs at http://climate.nasa.gov/vital-signs/sea-level/ to answer the questions below. (Note: To obtain exact data points, place your mouse on the section of the graph you would like to examine.)

Link is also listed in Blackboard

1. What is the source of the data for each graph?

2. Which years are covered by each graph?

3. Is one graph a better representation of global sea levels than the other? Why or why not?

4. By approximately how many millimeters did sea level rise between: a) 1910 and 1930?

b) 1930 and 1950?

5. What is the approximate average rate of increase of sea level rise between 1870 and 2000?

6. By how many millimeters did sea level rise between the first measurement obtained in January 1993 and the first measurement obtained in January 2013?

7. What is the approximate rate of sea level rise between January 1993 and present?

Examine the line graph for average global temperature at http://climate.nasa.gov/vital-signs/global-temperature/ and use it to answer the questions below. (link also provided on Blackboard)

8. By how much did the average global temperature change, and did it increase or decrease between 1910 and 1930? How about between 1930 and 1950?

9. Compare your answers to question number 8 with your answers to question number 4. Can you offer an explanation for the correlation or lack thereof?

10. What is the approximate average global temperature rise per year from the first measurement taken in 1880 to present?

Part 2

Go to the following website:

https://oceanservice.noaa.gov/facts/sealevel.html

Answer the following questions using the website.

1.Why is sea level NOT changing at the same rate globally?

2.How is sea level measured?

3.What are the two major causes of global sea level rise?

4.What percentage of the U.S. population lives high population density coastal areas?

Part 3

Now go to the following website: https://riskfinder.climatecentral.org/

1.Enter Annapolis, MD into the window to Explore Sea Level and Coastal Flood Risks.

What is the risk % of at least one flood over 6 ft taking place between today and 2050 in the Annapolis area?__________

2.Go back to the original page and enter another coastal location of your choosing.

What did you learn about that location?

Part 4

Here is some data about sea level rise in the Chesapeake Bay. The data shows the change in sea level over time. Notice that there are four sea level measurements per year because they are done during each season (fall, winter, summer, and spring).

Calculate the average sea level rise for each year and fill in the table above.

Now create an Excel graph (or use some graphing software) to portray the data from the table above. Insert the graph below.

According to the data how is the sea level rise changing over time?

Make a prediction for the 2020 measurements. What do you expect to see based on the data that has already been collected.
