Diatom assemblages in marine cores and sea salt deposition fluxes in ice cores have been used as sea ice proxies in the southern hemisphere. Here, a marine and an ice core proxy record for the Indian Ocean covering the last two glacial cycles are compared in order to illustrate their potential and limitations. The marine core was extracted in a location completely ice free under present-day conditions, and therefore was unable to record changes to the recent sea ice extent. Similarly, no sea...[Show more]
