Hi, I'm doing a science fair project about iron fertilization, and my partner and I want to show how the addition of iron to the ocean affects the growth of phytoplankton there. We know that iron fertilization works because many of the waters in the ocean are deficient in iron, specifically called high-nutrient low-chlorophyll (HNLC) waters. These places have almost all of the nutrients needed for phytoplankton to grow except iron. Iron is essential for phytoplankton to grow, so when iron is added to the deficient areas, more phytoplankton grows. When we grow phytoplankton for our experiment, we want to recreate a similar environment so that the water is abundant in other nutrients (such as nitrate, phosphate, and silica) required for phytoplankton growth, but still deficient in iron. This way, when we add different amounts of iron to the experimental groups, the iron will actually make a difference in the growth of the phytoplankton. Can you help us figure out a way to simulate or obtain this type of ocean water without actually going to the ocean? Thanks.
