资源简介:
Sediment depth is given in mbsf. Abundance estimates as follows: Abundance: A = abundant, C = common, F = few, R = rare, 1 = single, B = barren, - = not found.
沉积物深度的计量单位为海底以下米(meters below seafloor,mbsf)。丰度估算标准如下:丰度等级对应关系为:A代表丰富(abundant),C代表常见(common),F代表少量(few),R代表稀少(rare),1代表仅单个出现,B代表贫瘠(barren),符号“-”代表未检出(not found)。
