资源简介:

Sediment depth is given in mbsf. Species abundance: V = very abundant (more than 10 specimens per field of view), A = abundant (1-10 specimens per field of view), C = common (1 specimen per 2-10 fields of view), F = few (1 specimen per 11-100 fields of view), R = rare (1 specimen per 101-1000 fields of view). Samples 129-801A-7R-1,37 (39.37 mbsf) to 129-801A-13R-CC (Chert); 129-801B-10R-1,65-66 to 129-801B-25R-1,56-57 and 129-801B-27R-1,45-46 (415.15 mbsf) to 129-801B-43R-3,115-116 (504.35 mbsf) are barren.

沉积物深度单位为海底以下米(meters below seafloor, mbsf)。物种丰度分级标准如下:V为极丰富(单视野内标本数大于10),A为丰富(单视野内1~10个标本),C为常见(每2~10个单视野见1个标本),F为稀少(每11~100个单视野见1个标本),R为极稀少(每101~1000个单视野见1个标本)。下述样品均为无生物(无化石)样品:129-801A-7R-1、37(深度39.37 mbsf)至129-801A-13R-CC(燧石层);129-801B-10R-1、65-66至129-801B-25R-1、56-57,以及129-801B-27R-1、45-46(深度415.15 mbsf)至129-801B-43R-3、115-116(深度504.35 mbsf)。
