Raw and processed radio-echo sounding data for Rivgojiehkki, northern Sweden
Zhuo Wang, Neil Ross, Nina Kirchner
This dataset contains the raw and processed radio-echo sounding (RES) data collected on 2024-03-25 on Rivgojiehkki, Northern Sweden.
RES surveys were conducted at high spatial density, covering most of the glacier surface. The total length of the RES survey profiles is 57.6 km.
Rivgojiehkki (Swedish name: Riukojietna) is one of Sweden’s four so-called reference glaciers (glaciers for which more than 30 years of continuous measurements are available) included in the World Glacier Monitoring Service (WGMS) database.

Data description
The data are provided in two folders. Total size: 255 MiB.
Original_data
Two Hierarchical Data Format (HDF5) files, each representing a RES profile. The files include system parameters, data acquisition parameters, geolocations infomation, and raw RES data.

Processed_data
Two SEG-Y (SGY) files, each representing a processed RES profile corresponding to the raw RES data in the folder Original_data.
The data were processed using the ReflexW module for 2-D data analysis (Sandmeier Scientific Software, version 10.5).
The data processing flow, designed to enhance bed reflections, comprises time-zero correction, dynamic correction, 2-D filtering, and Kirchhoff migration.

Comments
Data collection
The data was collected by Blue System Integration ice penetrating radar (v3), towed behind a snowmobile (Mingo and Flowers, 2010). RES data were collected in an in-line antenna configuration, with antenna separation of 15 m, operating at a central wavelength of 16.8 m and a receiver sampling rate of 125 MHz.
The snowmobile was driven at a speed of 4–6 m/s. The RES signals were stacked 512 times during acquisition, resulting in a trace spacing of 4–6 m. The survey-line spacing along ice flow and across the ice flow direction are 40–180 and 90–160 m, respectively. The survey trajectory was tracked by the GPS receiver integrated into the RES system.
