Distributed temperature sensing data from a borehole drilled to the base of Sermeq Kujalleq (Store Glacier), Greenland, in July 2019

ABSTRACT: This is distributed temperature sensing (DTS) data from a 1,043 m borehole drilled to the base of Sermeq Kujalleq (Store Glacier), Greenland, 28 km inland from the glacier terminus. The DTS system was installed on 5 July 2019, with recordings continuing until cable failure on 13 August 201...

The processed data can be viewed using the Python files in the root directory. The packages used in the creation of these scripts are found within Python_env_packages.txt . dtscalibration is dependent on specific versions of some packages, so if you are having trouble getting things going I recommend checking your package versions. If you are just wish to visualise the data, then use 3_plotting.py which will produce the figures used in the publication unless ch1_full_processed.nc or ch1_end_processed.nc have been overwritten. If you're doing this there is no need to download the raw DTS data contained in /channel_1 and /channel_3 Running 1_full_process.py and 2_end_profile will overwrite ch1_full_processed.nc and ch1_end_processed.nc respectively. As supplied, if you do generate new files they should be identical to the ones already present. These files are probably most helpful if you wanted to process a new DTS dataset and needed an example, though better guidance on the dtscalibration package is avaiable at: https://github.com/dtscalibration/python-dts-calibration/tree/master/examples . A full processing run through takes about 30 mins on a 2018 i7 processor. *sample number varies from 11078 to 11079, probably a result of a minor change in fibre refractive index with temperature. The dtscalibration package is not yet adapted to account for these variations automatically. text/plain application/zip https://doi.org/10.17863/CAM.65812 https://www.repository.cam.ac.uk/handle/1810/319190 unknown https://doi.org/10.1126/sciadv.abe7136 https://www.repository.cam.ac.uk/handle/1810/322796 doi:10.17863/CAM.65812 https://www.repository.cam.ac.uk/handle/1810/319190 Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) https://creativecommons.org/licenses/by-sa/4.0/ Greenland Distributed temperature sensing DTS Store Glacier Glacier borehole Ice temperature Marine-terminating glacier Dataset 2021 ftunivcam https://doi.org/10.17863/CAM.6581210.1126/sciadv.abe7136 2023-07-10T21:28:44Z ABSTRACT: This is distributed temperature sensing (DTS) data from a 1,043 m borehole drilled to the base of Sermeq Kujalleq (Store Glacier), Greenland, 28 km inland from the glacier terminus.
