IODP Expedition 361 Magnetic susceptibility (section half)
<p>Magnetic susceptibility was measured on section halves on the Section Half Multisensor Logger (SHMSL) using a Bartington MS2 meter and either a MS2E or MS2K probe. Because all JRSO cores meet minimum size requirements for these two probes, MSPOINT data are corrected for volume and recorded in SI susceptibility units (x10<sup>-5</sup>).</p>

<p>Magnetic susceptibility was measured on section halves on the Section Half Multisensor Logger (SHMSL) using a Bartington MS2 meter and either a MS2E or MS2K probe.

IODP Expedition 362 Thin section images
<p>Hard rock and sediment thin section images were acquired using either the JRSO-developed Petrographic Image Capture and Archival Tool (PICAT) imager or (rarely) an upright microscope and a digital camera. Sample images are acquired in unpolarized, polarized, and/or cross-polarized light. Image files are presented compressed by hole.</p>
IODP Expedition 362 Section-half images
<p>Digital section images were taken of the flat face of split cores on the Section Half Imaging Logger (SHIL) using a linescan camera at a resolution of 20 lines/mm (50 micron pixels). Cores were imaged as soon as possible after splitting to minimize color changes that occur through oxidation and drying. The SHIL produces TIF files as well as reduced-size JPG files. The TIF files are not kept online but users may request them from the <a href="mailto:database@iodp.tamu.edu">IODP-JRSO Data Librarian</a>.</p>
Geophysical data set for San Ramon Fault master section
<p>This data set is a multivariable analysis carried out in the San Ramon Fault (SRF) along a master section perpendicular to the main fault scarp. These data include: (1) a ~ 1 km long Electrical resistivity tomography (ERT) with a dipolo-dipolo configuration, 48 channels every 20 meters (named as the master section). (2) Differential GPS data with the location of the ERT electrodes and gravity stations. (3) Data of the gravity stations, with a Garmin GPS data. (4) Seismic data of an active experiment of 24 channels every 5 m, with several hammer strikes, which are explained in a text-document inside each seismic file (TRV_seismic_data and SRF_seismic_data). (5) Time-series of the Nakamura stations located along the ERT master profile. (6) The voltage decay curve of a TEM-station in the western edge of the master section, which is ready for modeling.</p> <p> </p>

Data of fossils and sections of the Geobiodiversity Database (GBDB)
<p>Geobiodiversity database (GBDB, www.geobiodiversity.com) is a comprehensive stratigraphic and palaeontological database and was started in 2006. It is geological section-based and include data of over 26 500 geological sections and over 114 000 fossil taxa.</p> <p>The stratigraphic data in the GBDB are based on those published in Chinese literature since 1920s. By November 2020, all stratigraphic horizons and nearly all published geological sections can be searched and browsed in the GBDB. The GBDB fossil occurrence data are included in the stratigraphic records and can be queried and outputted. The palaeontological data are linked to the fossil collections from individual geological sections and borehole cores. The data include taxonomy (species, genus, family, order, class and division), major group, synonym (opinion data with different authors) and description (key features). Most fossil collections and occurrences of all sections from China are included in the GBDB. Subsequent authors in further study amended a portion of fossil taxa from these sections. In this way, there are also plenty of opinion data in the GBDB.</p> <p>The GBDB was designed to facilitate regional and global scientific collaborations focusing on palaeobiodiversity, systematics, palaeogeography, palaeoecology, regional correlation, and quantitative stratigraphy.</p> <p> </p>
Evaluating registrations of serial sections with distortions of the ground truths. Supplemental data
<p><strong>Evaluating Registrations of Serial Sections With Distortions of the Ground Truths</strong></p> <p>This is the supplemental data for our paper on how to benchmark registrations of serial sections with ground truths. The files are named as follows:</p> <ul> <li>*_challenge.7z: local distortions and global rigid transformations applied, the input for the benchmark we used. Use this to test your rigid and non-rigid methods.</li> <li>*_local-only.7z: only local distortions applied.</li> <li>*_local-DIST.7z: the distortion maps for local distortions.</li> <li>*_SURF-rigid.7z: local distortions and global rigid transformations applied, rigid transformations undone with SURF-based rigid-only method. Local distortions remain. Use this if your method does not cope well with large rigid transformations.</li> <li>_*vis.7z: visualizations of distortions.</li> <li>_rigid_ground.7z: the real rigid transformations used in the global phase.</li> <li>*_ground.7z: the ground truth. All data fit each other, no distortions. Use this to compare your registration result to it.</li> </ul> <p>There are three main modalities and one further, as a reference:</p> <ul> <li>CT_*: µCT data, a rabbit lung, 600 images. (In ground truth, and local distortions, and global transformations we supply more images that went into the benchmark, 50 more from both beginning and end.)</li> <li>EM_*: an EM serial block-face (SBF-SEM) data set of adult mouse lung, 1000 images. (EM ground truth is individually normalized, see paper.)</li> <li>LS_*: a lung from the light sheet microscopy from a male 24 week-old rat, 300 images. (LS ground truth is individually normalized, too.)</li> <li>REAL_*: a region from real serial sections from a rabbit lung, 2 images.</li> </ul> <p>We also supply elastix parameter files.</p> <p>A preprint has been uploaded to <a href="https://arxiv.org/abs/2011.11060">arXiv</a>.
