| 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. |
