Objective:

The project undertaken by the stable isotope laboratory is designed to evaluate the sources of nitrogen to the coastal reefs of South Florida using the stable isotopes of nitrogen (15N and 14N) as a tracer. In order to accomplish this task analyses were performed on the following components from the Florida offshore ecosystem off Key Largo i) algal samples, ii) samples of fish, iii) samples of particulate organic material, and iv) sample of inorganic nitrogen in the water column.
