In any case, because there are unmeasured effects of global in- 

 creases in pollutant concentrations in deep sea sediments, it would 

 be prudent to learn about life on the abyssal plain and to inves- 

 tigate the transport, fate, and effects of pollutants. I encourage you 

 to continue to support research on deep ocean processes. 



I thank Mr. Saxton, Mr. Weldon, Mr. Pallone, and other mem- 

 bers of the subcommittees for their continuing efforts to improve 

 the knowledge base for developing environmental policy and for 

 their continuing and strong support of ocean programs. 



I will be pleased to address any questions. Thank you.
