The flux of carbon to the deep ocean can be measured directly by collecting sinking particles (living and dead microscopic organisms, faecal matter) in sediment traps, and indirectly using ...

we will perform CESM simulations with neodynium isotopes to simulate the Eocene Southern Ocean circulation and compare the model results with neodynium isotope records from shark teeth. Collaborators ...
