This project was prepared as part of a BioQUEST faculty development workshop entitled BioQUEST Summer Workshop 2006: Exploring Complex Data Sets at Beloit College in June 2006. The BioQUEST Curriculum Consortium is committed to the reform of undergraduate biology instruction through an emphasis on engaging students in realistic scientific practices. This approach is sometimes characterized as an inquiry driven approach and is captured in BioQUEST's three P's (problem-posing, problem-solving, and peer-persuasion). As part of this workshop groups of faculty were encouraged to initiate innovative curricular projects. We are sharing these works in progress in the hope that they will stimulate further exploration, collaboration and development. Please see the following links for additional information:

Brief Overview:

We looked at the correlation between dissolved oxygen and two water quality variables: dissolved nitrogen and dissolved phosphorus. We thought that, if dissolved oxygen were highly correlated with dissolved nitrogen (for example), then that would imply that dissolved nitrogen was limiting or otherwise important at that site. Likewise for dissolved phosphorus. We found that different sites int eh bay had different levels of correlation, but there was no spatial pattern to the data.

Resources and References:

  • Eyes on the bay. A list of the water quality monitoring sites in Chesapeake bay. This is useful for finding stations, but it is hard to get large amounts of data from it.
  • Chesapeake bay data hub. This is the site to get large data files from.


Future Directions:

We could apply this technique to other parts of the bay and attempt to correlate the sensitivities to N and P with soil type, etc.
