Fossil diatom and geochemistry data from an 11,000 year lake sediment core from Isla Hornos, Cape Horn Archipelago

This dataset contains geochemistry measurements and fossil diatom data from a sediment core retrieved from Isla Hornos, in the Cape Horn Archipelago (''IHL'', -55.97 S, -67.28 W, 156 m asl). The dataset consists of diatom relative frequencies, ITRAX scanning XRF counts, ICP-MS and ICP-OES elemental composition, C percent, N percent, S percent, TEX-86-based lakewater temperature reconstructions and magnetic susceptibility measurements. Ages of the sediment samples were assigned based on an age depth model derived from 14C measurements and span the last c. 11,000 years.
