Description

Subglacial radio-tagged particle tracking dataset from the snout marginal zone of the Otemma Glacier, southwestern Switzerland. 324 RFID-tagged particles injected into a snout-marginal subglacial channel were tracked from the glacier surface using RFID antennas as they were transported downstream in the mid to late 2021 melt season. Data collection was performed following the particle tracking methodology detailed in Jenkin et al. (2023). Downstream transport distances were derived as detailed in the Supporting Information to the article "Coarse Sediment Transport in a Near-terminus Subglacial Channel".

The files will be made publicly available on January 1, 2027.

Reason: The authors have a manuscript in review using this dataset to describe bedload mobility in a subglacial channel. The embargo will be released on publication.
