BOTTOM SEDIMENT ANALYSIS SHEETS 



Results of bottom sediment analysis performed by the U.S. Naval Oceanographic 

 Office are recorded on sediment analysis sheets. 



The following Items are descriptions of the terms employed on the sediment 

 analysis sheets: 



1 . Sample Number . This number has 3 parts: 66 (the area) 



1 (the station number) 

 1 or 2 (the sample number at the station) 



2. Latitude. Expressed in degrees, minutes, and seconds . 



3. Longitude. Expressed in degrees, minutes, and seconds. 



4. Date. Day (GMT), month, and year. 



5. Sampler Type. Identified by name of device employed. Shown only for core. 



6. Water Depth (fm.). The uncorrected sonic sounding recorded in fathoms. 



7. Core Length (in.). Recorded in inches as observed in the laboratory. This 

 information is not given when a grab sampler was employed. Shown only for cores. 



8. Core Penetration (in.). Recorded in inches as observed in the field. This 

 information is not given when a grab sampler was employed. Shown only for cores. 



9. Laboratory Number . A reference number assigned to a fraction of a sample 

 retained by the Laboratory. 



10. Subsample Depth in Core (in.) . Interval of the subsample as measured from 

 the top of the core. Not applicable for a ^rab sample. Shown only for cores. 



11 . Color . Based on the Geological Society of America Rock-Color Chart. For 

 those samples where color was not determined in the field, the sample was moistened 

 in the laboratory for a color determination. 



12. Odor. A qualitative description of any noticeable odors . 



13. Wet Density (lbs/ft'^) . Not determined . 



14. RIgidense (mm) . Not determined . 



15. Maximum Porosity (%) . Not determined , 



16. Minimum Porosity (%) . Not determined . 



17. Water Content (%) . Not determined. 



18. Organic Carbon Content (%) . Not determined ,
