The Cenozoic geological era has seen the transition from a warm “greenhouse” climate, with limited or absent cryosphere, to one with large ice sheets in either hemisphere. Much of what we know about the evolution and development of Cenozoic glaciations comes from records far removed from the polar regions, in particular marine isotope and eustatic sea level records. These records provide a high‐resolution, continuous but indirect record of global ice volume changes through time. However, identifying the geographical distribution of ice sheet evolution in either hemisphere through time has proved difficult due to the sparse, discontinuous, and inaccessible nature of geological records in polar regions.
