Abstract:
These data are relative abundance (%) and absolute abundance (valves per gram dry weight) for diatoms identified to the species level. The core was collected at 60 degrees South in 4 km water depth. The age model is based on paleomagnetic reversals, and gives ages of 1.110 to 1.1030 Ma for the analyzed samples. The sampling resolution is approximately 1 ka.
File description: An excel file containing diatom data as well as age and depth.
