Phosphorus is an important element in fresh and saline waters. In fresh waters, phosphorus limits plant production, but in saline waters nitrogen limits growth. In this study, supervised by Dr. Tom Jordan, we are looking at a gradient from fresh to saline waters in the Patuxent River to see how the change of limiting elements occurs. My research project for the summer looks at the fractions of inorganic phosphorus in the sediments, which is where most of the phosphorus is stored and released. By looking at fractions bound to iron, we can see how the chemistry of the phosphorus changes as salinity changes.
