sediment type in the area, in suspension and move the suspended load at 

 approximately 3 kilometers per day. Ths explanation is further substantiated 

 by comparing the sediment screening results shown in Table 3-5 for Evergreen 

 station B and Endeavor station G-42. The former based on samples taken in 

 December, indicate a clean bottom; the lattei^, based on samples taken in 

 February, indicate the presence of Argo Merchant oil. The conclusion arrived 

 at is that the movement of the tanker's bow section, after it was sunk on 

 December 31, over the sand bottom mechanically worked oil into the sediment 

 and these sediments are being transported by the southwesterly bottom cur- 

 rents in the area.
