Regional variability of diatoms in ice cores from the Antarctic Peninsula and Ellsworth Land, Antarctica

Dieter R. Tetzner, Claire S. Allen, and Elizabeth R. Thomas

Data sets

Annual and sub-annual diatom abundance and distribution in the Jurassic, Roth- schild Island, Sherman Island and Sky-Blu ice cores (1992–2019 CE) (Version 1.0) D. Tetzner, C. Allen, and E. Thomas https://doi.org/10.5285/E7166724-E7FA-4267-A2A7-6207EDE57F70

Short summary

The presence of diatoms in Antarctic ice cores has been scarcely documented and poorly understood. Here we present a detailed analysis of the spatial and temporal distribution of the diatom record preserved in a set of Antarctic ice cores. Our results reveal that the timing and amount of diatoms deposited present a strong geographical division. This study highlights the potential of the diatom record preserved in Antarctic ice cores to provide useful information about past environmental changes.
