Nd isotope composition obtained on mixed planktonic foraminifera samples from core MD90-917 ...
Neodymium isotopes were measured on mixed planktonic foraminifera from the washed >150 µm size fraction of the samples. The foraminifera tests were crushed between two glass slides to open chambers and fragments were ultrasonicated for 1 min in MilliQ water before pipetting out the suspended part...
