Color b* value of sediment core LV76-21

The color b* values are widely used as a paleoproductivity proxy for the NW Pacific and its marginal seas (Nürnberg and Tiedemann, 2004; Riethdorf et al., 2013). The color b* index was measured onboard after sediment core splitting at 1 cm resolution using a Konica Minolta CM-700d spectrophotometer.

色度b*值（color b*）被广泛用作西北太平洋（NW Pacific）及其边缘海的古生产力代用指标（Nürnberg与Tiedemann，2004；Riethdorf等，2013）。以1厘米分辨率对沉积物岩心进行劈分后，使用柯尼卡美能达CM-700d型分光光度计在船载现场完成了色度b*指数的测定。
