We will now look at phytoplankton in dead zones, harmful algal blooms and the role of phytoplankton in absorbing carbon dioxide and influence climate.
We will next join the SOFeX to test the "iron hypothesis" -- an intriguing speculation on engineering climate change by stimulating phytoplankton blooms.
Learning Objective: Students will learn about the role played by microscopic organisms, phytoplankon, in the health of the ocean and global climate, in general. Next, students will learn about the potential of the disposal of carbon dioxide, CO2, in the deep waters of the ocean, a process known as carbon sequestration. Students will then join a virtual research voyage to the Southern Ocean to study the effects of iron fertilization on phytoplankton populations and its relationship to the carbon cycle and carbon dioxide accumulation in the atmosphere. Finally, in a required discussion, students will critically assess the scientific and ethical merits of geoengineering the ocean to address the buildup of carbon dioxide in the atmosphere.
