Resources for "Mapping glacier bed topography in crevassed regions: a new passive seismic reflection method applied to Isunnguata Sermia, West Greenland"

This dataset contains data and codes used for the paper "Mapping glacier bed topography in crevassed regions: a new passive seismic reflection method applied to Isunnguata Sermia, West Greenland". The following files are provided: MFP event catalog for frequency range 4-6Hz (event_list.csv) Station list file (station_list_2023_rel_coords.csv) Stream object for each event, which contains the vertical component of all stations and synchronized in the 4--6 Hz frequency range (in data.zip) Synchronization parameters file for the 40--80 Hz frequency range (synchronization_parameters_40_80Hz_new.npz) Precomputed CMP (no topography correction) CDP (with topography correction using BedMachine v5) locations (CMP.npz) Outline of the surface elevation anomalies from Livingstone et. al, 2019 (Lakes.mat). Background image for the maps (photoaerienne_reseau_2024.tif) Radar bed picks (radar_bed_picks.csv) Two python scripts require the functions in "utils_reflections.py" and should be run in an order following their number: "refl_01_compute_CMPs_loc.py" : (optional) generates the file "CMP.npz" that contains the location of the CMP (no topography correction) and CDP (+ static time shift correction) for all event-station pairs. The output "CMP.npz" of the script using BedMachine v5 is provided. "refl_02_Pwave_bed_reflectionsv3.py" : Creates the gathers, measures the ice thickness and generates summary figures (summary_figures/summary_cell_(5,12).pdf) is Figure 2 from the paper). A notebook "Figure3.ipynb" is provided to generate Figure 3 from the paper.
