Vertical flux reconstruction for sediment cores off Chile

Biogenic opal and organic carbon vertical rain rates in sediment cores reveal a strong cyclicity in the productivity of the upwelling system off presently arid northern Chile...沉积岩芯（sediment cores）中的生物成因蛋白石（biogenic opal）与有机碳（organic carbon）垂直沉降速率揭示了现今干旱的智利北部近海上升流系统的生产力存在强烈周期性变化……
