APPENDIX B 



CORE DATA AND SEDIMENT DESCRIPTION 



Appendix B contains graphic size distribution plots and visual 

 description of sediments contained in cores from the study area. 



Size distribution curves for selected samples are identified by 

 notations on each curve showing depth of sample below the water- 

 sediment interface. 



Visual descriptions are based on both megascopic and microscopic 

 examination. The descriptive statement generally contains (in order) 

 the following elements: 



1. Color descriptor 



2. Color code per Munsell Soil Color Charts (1954 ed.)* 



3. Dominant size or size range. 



4. Major compositional element or elements with the 

 dominant constituent listed last. 



5. A phrase identifying readily recognized constituent elements 

 with an estimated percentage occurrence in terms of total 

 particles. 



Described subdivisions of the core are indicated by limiting lines 

 dra\-.Ti across the graphic scale to the left of the descriptions. The 

 hachured line shows the depth to the bottom of the hole.
