Annual and sub-annual diatom abundance and distribution in the Jurassic, Rothschild Island, Sherman Island and Sky-Blu ice cores (1992-2019 CE)
This dataset presents the annual and sub-annual diatom records preserved in a set of ice cores from the Antarctic Peninsula and Ellsworth Land over the 1992-2019 CE interval, as presented in Tetzner et al. (2022). Annual diatom abundance (annual d-abundance) data are provided as annual averages for the 1992-2019 CE interval. Annual diatom concentration (annual d-concentration) data are provided as annual averages over the 1992-2019 CE interval. Sub-annual diatom concentration (sub-annual d-concentration) data are provided for each ice core as depth profiles for the 2002-2006 CE interval.
Annual d-abundance and d-concentration are timeseries. Column A represents years between 1992 and 2019 CE. Annual data are listed for each ice core site alphabetically (Jurassic (JUR), Rothschild Island (ROIC), Sherman Island (SHIC) and Sky-Blu (SKBL)). Sub-annual d-concentration data are depth profiles. Column A represents ice depth (m). The ice depth interval presented in each file represents the 2002-2006 CE interval. Diatom abundance data are presented as the number of diatoms identified in an ice core annual layer (diatoms a-1). Diatom concentration data are presented as the number of diatoms identified per unit volume of water (L) contained on each annual (or sub-annual) sample (diatoms L-1).
This dataset was created with the support of the Comision Nacional de Investigacion Cientifica y Tecnologica (grant number 72180432).

Methodology:
All data were obtained using the discrete sampling method presented in Tetzner et al. (2021). Diatom abundance and diatom concentration records were obtained from discrete annual and sub-annual ice core samples. Discrete annual and sub-annual ice core sections were established based on each ice core hydrogen peroxide (H2O2), non-sea salt sulphate (nssSO4) and MSA annual cycle.
Data collection:
All data were obtained using the discrete sampling method presented in Tetzner D, Thomas ER, Allen CS and Wolff EW (2021) A Refined Method to Analyze Insoluble Particulate Matter in Ice Cores, and Its Application to Diatom Sampling in the Antarctic Peninsula. Front. Earth Sci. 9:617043.
Data quality:
Diatom abundance and concentration records were obtained by filtering ice core meltwater, following the methods and procedures outlined in Tetzner et al. (2021). Method and procedures were developed using polystyrene microspheres and validated after running duplicates.
Missing data are presented as -999.99.
