APPENDIX A 



CORE SEDIMENT DESCRIPTIONS 



This appendix contains core sediment descriptions, based on both 

 megascopic and microscopic examination, from sampling locations shown 

 in Figure 8. Sediment color is based on damp samples. 



Sediment names are based on the following Wentworth size scale:
