Subglacial particle tracking dataset from the Otemma Glacier, southwestern Switzerland

Subglacial radio-tagged particle tracking dataset from the snout-marginal zone of Glacier d'Otemma, southwestern Switzerland. A total of 324 active RFID-tagged pebbles and cobbles were injected into a snout-marginal subglacial channel and tracked from the glacier surface using RFID antennas as they were transported downstream during the mid to late 2021 melt season. Data collection followed the active-RFID particle tracking methodology described in Jenkin et al. (2023) and its related Zenodo method archive. Manuscript-specific trajectory interpretation and analysis are described in "Coarse Sediment Transport in a Near-Terminus Subglacial Channel" and its Supporting Information, accepted for publication in Geophysical Research Letters on 16 June 2026.
