This deposit contains the data set we used in our paper ‘Dynamic imaging of glacier structures at high-resolution using source localization with a dense seismic array’. The paper is in review for GRL and a preprint can be found here: 10.1002/essoar.10507953.1. The dataset present here contains 34 files named ‘beam_15423_jd***.h5’. These files correspond to the output of the matched field processing for each day. They are in .h5 format and we provide a matlab code (read_MFP_data.m) to read these files. These files can be read with any other language since they are in . h5. In linux you can use h5dump –A filename.h5 and you can see the content of each files. More information on how the MFP process is conducted can be found in on the website dedicated to this aspect or on our paper. The whole procedure and associated codes is provided on the lecoinal.gricad-pages.univ-grenoble-alpes.fr/resolve/. We also deliver with this deposit one day of seismic data ZO_2018_121.h5 that can be used to test our MFP process. The data corresponds to the signal measured for 24 hours at each of the 98 sensors with a sampling rate of 500 Hz. More information on these seimsic signals can be found on our website and the whole seimsic dataset can be found here https://seismology.resif.fr/networks/#/ZO__2018. Detailed for downloading the dataset should be search on our website. Other dataset linked to this project are: Nanni, Ugo, Gimbert, Florent, Roux, Phillipe, & Lecointre, Albanne. (2020).
