APPENDIX A: INFORMATION ON SEDIMENTS 

 NEEDED FOR IDEAL GEOACOUSTIC MODEL 



A. Location, ship, and equipment data. 



1. Sample identification: station and sample 

 numbers, ship, expedition, personnel. 



2. Geographic data: latitude, longitude, date, 

 time, water depth (echo sounder, true, or corrected). 



3. Sampling equipment used (description or 

 cross reference). 



4. Operation of sampling (if anything unusual). 



5. Field descriptions of results, including 

 description of sediment or rock samples, degree of 

 disturbance and recovery, etc. 



B. Laboratory measurements, analyses, and com- 

 putations (designed to yield lateral and vertical gradients 

 of the properties noted). 



1. Grain size analysis, to yield median diameter 

 percentages of sand, silt, and clay, and sediment nomen- 

 clature (e.g., "silty clay"). 



2. Porosity. 



3. Density. 



a. Saturated, or bulk; 



b. Of solids (minerals); 



c. Of interstitial water. 



4. Static shear strength (soil mechanics test).
