Literature Assignment 2

We will discuss the assigned paper (Feely et al. 2010) on Mar. 7 in class. Before coming to class, prepare a summary (described below) to be turned in as part of your grade for this assignment (30 points). The remaining 10 points will be based on active participation in the discussion of the paper.

The written summary should include the following:

 A brief summary of the scientific relevance, methods and significant results reported in the paper. Please do not restate the abstract. This should be in your own words.
 At least 3 questions that you have about the paper. These could be things that are unclear in the writing or they could be concepts and methods that you have not previously encountered.
 3 criticisms about the paper (methods, interpretation, writing, presentation of data/graphs)
 3 positive aspects of the paper (things that were done well)
 1 or more suggestions about future work or needs for additional information that might follow the reported results

For specific questions/comments/criticisms cite the page and paragraph you are referring to.

In addition, I want you to answer (in writing) the following in reference to this paper. These are basic aspects of the paper that are essential to understanding it. It’s up to you to figure these out ahead of time so that we can focus on more advanced aspects of the paper during the discussion.

1. a. What are calcite and aragonite?

b. In your own words, describe what the calcite and aragonite saturation indices are, how they are determined and why they are important.

c. What does the term “apparent stoichiometric solubility constant (Ksp*) refer to?

2. If ocean pH were to drop by 0.3 pH units, what would that mean in terms of a change in [H+]?

3. What is a Niskin bottle?

4. How would remineralization of organic matter result in decreased pH?

Grading of the written assignment will focus on the clarity of the critique and the degree to which points are successfully articulated (i.e., don’t just say “I didn’t understand Graph 3”).

In the class discussion we will consider both the scientific merit and the technical preparation of the paper.
