Exploring Primary Productivity

Catherine Hill, Arizona Western College

Author Profile

Summary

Interacting with Data: Using interactive on-line graphs and datasets created by the Ocean Observatories Initiative (OOI) from data collected from six oceanic arrays using hundreds of instruments, students can explore the relationships between chlorophyll production and multiple variables. They record their observations and extrapolate generalizations.

Teaching Notes and Tips

You will need to be lenient on the specific datapoints identified by students as Maximums and Minimums as well as certain seasonal dates. There is a lot of data in these graphs. Sometimes they spot points that I have overlooked!
