Bothner asked about the relative importance of dissolution of barium and 

 transport in mass balance studies. Ray responded that results to date don't

 Mass balance studies on the shelf predict higher levels of barium than are 

 actually present. 



Note: The studies reviewed will be completed and available by the end of the
