The method uses diatoms to determine how intensively the salinity of ocean surface waters has declined, e.g. due to meltwater deposition. By performing an oxygen isotope analysis on the remains of the siliceous hardparts of diatoms preserved in the sediment record, the researchers were able to identify at what times the surface salinity was most intensively affected by melting ice.
