资源简介:
Sediment depth is given in mbsf. Abundance estimates as follows: V = very abundant, A = abundant, C = common, F = few, R = rare, B = barren, - = not found.
沉积物深度以海底以下米数(meters below sea floor, mbsf)为单位。丰度分级标准如下:V = 极丰富(very abundant),A = 丰富(abundant),C = 常见(common),F = 少量(few),R = 罕见(rare),B = 贫瘠(barren),符号"-"代表未检出(not found)。
