Ocean Acidification: Too Much of a Good Thing?
How will individual species and ecosystems respond as oceans become more acidic?
In Part A, you will analyze a time-series graph to search for relationships between trends in atmospheric CO2, dissolved CO2 in seawater, and changes in ocean pH. Then, you will carry out a class experiment on the effects of increased amounts of CO2 on pH in sea water.
In Part B, you will review and analyze the results of research compiled by the Woods Hole Oceanographic Institute on the effect of ocean acidification on a variety of marine organisms. You will then carry out a virtual l - the Virtual Urchin - to study the effect of a more acidic seawater pH on sea urchin larvae.
After completing this investigation, you should be able to:
- Explain what ocean acidification is and why it is happening.
- Describe ways in which individual species and marine ecosystems might respond to ocean acidification.
- Describe how ocean acidification will impact the ability of oceans to sequester carbon
Keeping Track of What You LearnThroughout these labs, you will find two kinds of questions.
- Checking In questions are intended to keep you engaged and focused on key concepts and to allow you to periodically check if the material is making sense. These questions are often accompanied by hints or answers to let you know if you are on the right track.
- Stop and Think questions are intended to help your teacher assess your understanding of the key concepts and skills you should be learning from the lab activities and readings.
