Measured biogenic opal percentage for sites J1002 and J1007, Chilean Margin@en

Sediment cores at sites J1002 and J1007 were collected from the Chilean Margin during D/V JOIDES Resolution Expedition 379T (JR100) in 2019. Sedimentary Green/Blue (G/B) ratio data were collected during the expedition. Measured biogenic opal contents were compared to the G/B to test the utility of G/B as a proxy for diatom productivity. Laboratory measurements in this study were conducted in 2020 at Rutgers University.2019年，在D/V乔迪斯·决心号（D/V JOIDES Resolution）第379T次航次（JR100）执行期间，科研人员于智利陆缘采集了J1002与J1007站位的沉积物岩芯。本航次同步获取了沉积物绿色/蓝色比值（G/B比值）数据。本研究将实测生物成因蛋白石含量与G/B比值进行对比，以验证G/B比值作为硅藻生产力替代指标的适用性。本研究的实验室测试工作于2020年在罗格斯大学完成。
