Slide 1

Slide 2 (explanation)
The following slide shows plots of oxygen isotope variation measured in shells of marine organisms over the past 6 million years.
Oxygen isotope ratios are used as a proxy for temperature change.
The three graphs show data from 0 to 2 million years ago (top), 2 to 4 million years ago (middle) and 4-6 million years ago (bottom). In each graph, dat progress back in time from left to right.

Slide 3
This slide shows sea-level (tidal) elevations for Glaveston Bay, Texas

Assignment # 2 – Systems & Equilibrium
Assigned: Wed., August 29 Due: Mon., Sep. 10
20 points

System Interactions:
Read the information about coral reefs from the EPA’s website contained in the PDF file called
Coral Reefs – USEPA
.
1. List three things that are known to disturb coral reef ecosystems. [3]
2. Do humans play a role in any of them? If so, how? [2]
3. Which type of disturbances are generally more damaging to reefs: natural, short-term ones, or human-induced, long-term ones ? [1]
Natural systems at equilibrium:

The following slides are contained in the Powerpoint presentation called
Assignment 2 Slides. Each example shows a system that is exhibiting one of the three kinds of equilibrium we discussed: static, steady-state or dynamic.
Slide 1: Plot of recent carbon dioxide measurements at Mauna Loa, Hawaii
4. What type of equilibrium is exhibited by the Mauna Loa CO2 data? Explain your reasoning. [2]
5. Why do you think these measurements are taken at Mauna Loa rather than in a large city? [2]
Slide 2: Oxygen isotope data
6. What type of system equilibrium do you think is shown in each of the three plots (they don’t have to be the same answer)? Explain your reason for each example. [6]
Slide 3: Galveston Bay
7. For the entire period of measurement, what type of equilibrium is shown? Explain your reasoning. [2]
8. Suppose the only data available were the measurements made during the time period between the two arrows. How (and why) would that change your assessment of the type of system equilibrium? [2]
