Planktonic Foraminifera test sizes from sediment core SAT-048A
Here we present 26,928 data points of planktonic foraminiferal shell sizes from 49 samples belonging to core SAT-048A, recovered from the western South Atlantic, spanning the 5-43 ka time interval. Sizes were extracted using imaging software. For the images acquisition, tests were positioned with th...
