Bulk and position-specific isotopic composition of N2O (total and in situ) and nitrate from the EDC, EDML, Vostok, TALDICE, Taylor Glacier, and NGRIP ice cores

The mixing ratio and bulk isotopic composition of nitrous oxide (N2O) was measured after wet extraction and purification of the air enclosed in 150 g ice core samples from EDC, EDML, Vostok, TALDICE, and NGRIP, following the analysis procedure described in Schmitt et al. (2014). The position-specific isotopic composition of N2O was measured after dry extraction and purification of the air enclosed in 600 g ice core samples from Vostok and Taylor Glacier, following the analysis procedure described in Menking et al. (2025). The mixing ratio and isotopic composition of in situ N2O – i.e., the fraction of N2O produced in the ice – was calculated using a mass balance approach (Soussaintjean et al., preprint). After gas extraction, the sample meltwater and ice chips were collected to measure the isotopic composition of nitrate (NO3-) following the bacterial denitrification method described in Erbland et al. (2013). Each sample was associated with its ice age and gas age based on the AICC2023 chronology (Bouchet et al., 2023) for EDC, EDML, Vostok, TALDICE, and NGRIP and Baggenstos et al. (2017, 2018) for Talyor Glacier. The samples cover the periods 11 – 26 ka, 41 – 75 ka, and 136 – 143 ka. Taylor Glacier is a horizontal core, meaning the age of the ice varies with distance along a transect close to the surface where the horizontal stratigraphy is preserved (Baggenstos et al., 2017).

ANT 2015/16: AWI airborne Radio-Echo Sounding data western DML over the Maud Belt and Ekström Ice Shelf (GEA-V-FMA project)

This dataset contains airborne radar data acquired using the AWI EMR system (Nixdorf et al., 1999) during the Arctic season of 2015. The profiles extend western DML over the Maud Belt and Ekström Ice Shelf to investigate the geodynamic evolution of East Antarctica, the Forster magnetic anomaly (GEA-V-FMA). The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.

ANT 2011/12: AWI airborne Accumulation Radar data over western DML around EDML, eastern DML over the Sør Rondane Mountains, and over Atka Bay (GEA and WEGAS Projects)

This dataset contains airborne radar data acquired using the AWI Accumulation Radar (ACCU) system during the Antarctic season of 2011/12. The profiles cover western Dronning Maud Land around EDML, eastern Dronning Maud Land over the Sør Rondane Mountains, and over Atka Bay. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.
