KTB Borehole Measurements Data - Data collection This data collection compiles the KTB Borehole Measurements Data of the German Continental Deep Drilling Program operated by the GFZ - German Research Centre for Geosciences. Extensive borehole measurements were performed during the active drilling phase of the KTB pilot and main hole. All KTB borehole measurements are described in detail in the Scientific Technical Report - Data 21/03 "KTB Borehole Logging Data" (Kück et al. 2021). The terms borehole measurements, downhole logging, and logging are used synonymously here. The KTB logging data files contain the final processed versions of the geoscientific borehole logging data from logs in the two KTB boreholes: • KTB-Oberpfalz VB (KTB Vorbohrung/Pilot Hole or KTB-VB) • KTB-Oberpfalz HB (KTB Hauptbohrung/Main Hole or KTB-HB). Here only the acronyms KTB-VB and KTB-HB are used. In total there are 145 logging data files from the KTB-VB and 239 logging data files from the KTB-HB. The data compilation comprises the following measurements: • Borehole geometry and orientation logs • Composite logs (compilation of standard logs of resistivity, gamma spectrum, density, neutron porosity, sonic) • Geochemical logs • Gravimetry logs • Magnetic susceptibility and field logs • Spontaneous potential and induced polarization (SP and IP) logs • Structures from borehole images, foliation, fracs, faults, joints • Temperature logs The maximum logging depth was 4001 m in the KTB-VB and 9085 m in the KTB-HB. There is no sonic waveform data available. There is no electrical or acoustic borehole wall image data available. However, the spatial orientation of planar structures (foliation, faults, fractures, joints) gained by manual sinus structure picking from these electrical images are included.
KTB Borehole Measurements Data Gravimetry inside the borehole Extensive borehole measurements were performed during the active drilling phase of the KTB pilot and main hole. The data report STR 21/03 KTB Borehole logging data contains the full description of the logging data given here. Please read it thoroughly to avoid inappropriate or wrong use of the data. The KTB borehole measurement data files contain the final processed versions of logging data from the two KTB boreholes: • KTB-Oberpfalz VB (KTB Vorbohrung/Pilot Hole or KTB-VB) • KTB-Oberpfalz HB (KTB Hauptbohrung/Main Hole or KTB-HB). Here only the acronyms KTB-VB and KTB-HB are used. In total there are 145 data files from the KTB-VB and 239 data files from the KTB-HB. All logs were run in open hole unless noted otherwise (see the file header). The maximum logging depth was 4001 m in the KTB-VB and 9085 m in the KTB-HB. The files of the Gravimetry measurements contain data from measurements made with a Lacoste-Romberg gravity meter sonde from the company EDCON, USA. The gravimetry logs are not depth corrected to the reference GR because the sonde had no GR sensor. The data are provided in ASCII format. Detailed descriptions are provided in the associated data report (STR 21/03, Kueck et al., 2021) and the KTB Borehole Measurements Catalog. Acknkowledgements: The GFZ German Research Centre for Geosciences, Potsdam, Germany, as successor of the KTB Project Management provides the logging data, which were obtained under grants RG8604, RG8803 and RG 9001 of the Federal Ministry of Research and Technology of Germany.

MSUS was only run in the KTB-VB. The Braunschweig magnetometer was run in both KTB boreholes and the GPIT only in the KTB-HB. The MSUS log and the magnetic field log in the KTB-VB are not depth corrected to the reference GR because the sondes had no GR sensor. Both types of magnetic field logs in the KTB-HB are depth corrected to the reference GR. The data are provided in ASCII format.

Global spherical harmonic paleomagnetic field model LSMOD.1 describes the magnetic field evolution from 50 to 30 ka BP based on published paleomagnetic sediment records and volcanic data. The time interval includes the Laschamp (~41 ka BP) and Mono Lake (~34 ka BP) excursions. The model is given with Fortran source code to obtain spherical harmonic magnetic field coefficients for individual epochs and to obtain time series of magnetic declination, inclination and field intensity from 49.95 to 30 ka BP for any location on Earth. For details see M. Brown, M. Korte, R. Holme, I. Wardinski and S. Gunnarson (2018): Earth's magnetic field is probably not reversing. PNAS, 115, 5111-5116.

This data publication includes standard rock magnetic data related to concentration, coercivity and magneto-mineralogy versus depth from six sediment cores (M72/5-22GC3, M72-5-22GC4, M72-5-22GC6, M72-5-22GC8, M72-5-24GC3, M72-5-25GC1), collected at the Arkhangelsky Ridge in the Southeastern Black Sea during the marine expedition M72/5 of the German research vessel RV METEOR (in May 2007). The data are related to publications by Liu et al. (2018, 2019, 2020), Liu (2019) and Nowaczyk et al. (2012, 2013, 2018, 2021a, b). Sediment cores were recovered using gravity corers. For paleo- and rock magnetic analyses clear plastic boxes of 20×20×15 mm were pressed into the split halves of the generally 1 m long sections of the sediment cores. Data are provided as six ASCII files (.dat, one for each core) with metadata header, followed by 12 data columns and are decribed in the associated data description file (pdf).
