Another major area that I think needs work from the geo¬ 
logical, sedimentological, and toxicological perspective is that 
we must develop a series of models of suspended sediment 
movement linked to a two-dimensional or three-dimensional model 
of the Chesapeake, We must put suspended sediments in those 
models because toxic materials that enter the Chesapeake Bay 
seem to cling to and have an affinity for suspended sediments. 
Where the sediments go, so go most of the toxic materials. 
Perhaps, we're going to go to no-till agriculture in the 
Basin because it's an economic imperative. When we go to no¬ 
till agriculture, if we reduce the suspended sediment input to 
the Chesapeake Bay, we'll increase the light that's available to 
the Bay. Some would say that given the nutrient concentrations 
that we have at the present time, light is the limiting factor 
that controls primary production in the Bay. How long will it 
take the effects of no-till agriculture to increase water 
clarity? Where will it be achieved first? How will these 
interact with the nutrients of the Bay? 
These are some problems that we think are of critical im¬ 
portance from the perspective of geology and sedimentology that 
need to be addressed in the Chesapeake. 
Thank you.
