GRAPE density of ODP Site 145-887
New composite GRAPE WBD profile from our new splice at ODP site 887. The composite depth scale for site 887 was created by visual correlation of the shipboard GRAPE WBD measurements between 887A and 887C cores 11H and 12H. 887C 11H-1 0–12 cm and 887C 12H-1 0-35 were not considered in the correlation...
