We present new #leafwax hydrogen and carbon isotope records from the sapropel layers in the eastern Mediterranean going back to 4.5 million years ago

We find prominent 400-kyr and 1-Myr cycles present in the δDprecip record that align well with the same periodicities in low-latitude insolation, indicating strong influence from low-frequency orbital cycles over northeast Africa (where the waxes are sourced from)
