       Existence and uniqueness for a steady state algal bloom model, Bevin Maultsby, School of Mathematics
       Algae in the ocean absorbs carbon dioxide from the atmosphere and thus plays an important role in the carbon cycle. A bloom occurs when there is a rapid increase in an algae population. We will look at a reaction-advection-diffusion model for algal bloom density and examine an analytic uniqueness result for the steady state equation (with mixed boundary conditions). In particular, we will show that given a bloom depth L>0, there is only one possible solution for the algal bloom's density profile.
