Performance task #3 1. Hypothesis: If you fertilize the ocean with iron then, it will help reduce atmospheric carbon dioxide levels. 2. Step-by-Step procedure: 1. Dissolve 7 metric tons of iron sulfate in acidic sea water.?? 2. Spew the solution into a ships propeller wash on a specific date covering a circular patch in the eddy. 3. Cover in iron in a circular path for 167 square km (0.01 grams per square meter. ? 4. Monitor the fate of the patch, off and on for 5 weeks while adding supplemental iron fertilizer after every 2 weeks to keep concentrations high enough to promote growth. ?? 5. Record the microscopic life bloomed on a data table.
