conditions; 2) to evaluate the fluorescence properties of field sediments in relation to 

 expected (laboratory-based) PAH distribution/concentration measurements; 3) evaluate the 

 spatial patchiness of PAHs in undisturbed (i.e., in-situ) material sediments; and 4) evaluate 

 the ability of UV-R to distinguish differences in PAH distribution within the sediment 

 column. The results of the investigation will be discussed relative to these four objectives; 

 recommendations for additional system improvements, data analysis, and data needs are 

 also provided.'
