Data from: Lower Jurassic foraminifera from the Llanbedr (Mochras Farm) Borehole, North Wales, UK
The complete, fully cored Lower Jurassic (Hettangian, Sinemurian, Pliensbachian, Toarcian) succession from the Llanbedr (Mochras Farm) Borehole, North Wales, the thickest known British section, has yielded a diverse and well preserved foraminiferal fauna, comprising 270 species and subspecies which are described and illustrated. An additional nine taxa, not encountered at Mochras, are also described. This typical European Boreal Atlantic foraminiferal fauna is dominated by members of the Lagenida, with the Ceratobuliminoidea, Miliolida, Spirillinina, Involutinina, Buliminida and Textulariida as important accessory groups. The Ceratobuliminoidea and Miliolida are unusually diverse, with Reinholdella and Ophthalmidium being notably abundant. The presence of the family Oberhauserellidae is significant. A benthonic foraminiferal biozonation scheme for the Lower Jurassic, comprising 16 biozones and tied to the standard ammonite-based chronostratigraphy, is described in detail. It is recognizable across the northern European Boreal province and as far south as Spain and France, and is applicable to subsurface hydrocarbon exploration of the UK continental shelf and onshore Europe. Three new genera (Duoplanum, Extonia and Haynesella) are described as well as 19 new species (Citharina sherringtoni, Duoplanum inaequale, D. leve, Glomospirella liassica, Lagena? haeusleri, L. semisulcata, Lagenammina pseudofusiformis, L. tangentia, Loxostomum liassicum, Marginulina turneri, Neobulimina bangae, Nodosaria pseudoclaviformis, Ophthalmidium strictum, Reinholdella? mochrasensis, R. robusta, Reussoolina? lacrimaforma, Semiiinvoluta excelsa, Tubinella pseudoinornata, and Vinelloidea lordi), and 10 new subspecies (Berthelinella involuta striata, Ichthyolaria terquemi barnardi, I. terquemi mediumcostata, Lenticulina varians barnardi, Loxostomum liassicum liassicum, L. liassicum teres, Ophthalmidium macfadyeni tenuiloculare, Paralingulina cernua ssp. A, Reinholdella margarita dorsoplana, and R. pachyderma humilis). Two further species are renamed as Nodosaria whittakeri and Paralingulina paranodosaria .

<p>These are the four supplementary data files for a paper accepted in the Journal of Geophysical Research (JGR), "Initial results from the Oman Drilling Project Multi-Borehole Observatory: Petrogenesis and ongoing alteration of mantle peridotite in the weathering horizon", 2021JB022729R, which are being uploaded here in conformance with JGR's requirement that data be placed in an open archive. The date of publication is not yet known, but JGR requires that the data be uploaded when the paper is accepted, so we have used the date of acceptance, November 20, 2021.</p>

Calibration of a movable heat pulse probe in borehole for measuring horizontal groundwater flow velocity in deep aquifers
<ul> <li>In the laboratory, 42 heat pulse experiments with 7 different Darcy’s velocities and 6 different heating powers had been done. The results are summarized in a relationship of temperature increase with time.</li> <li>The temperature responses were continuously monitored over a 30min period. Data were collected every 2s throughout the recording period. In order to strictly monitor the actual power to the heater, the voltage and current delivered to the heater were also recorded simultaneously with the temperature.</li> <li>The heater was switched on and lasted for 1 min to generate a heat pulse. The time when the heater was switched on was selected as the initial time of data analysis.</li> </ul>

Data from: A national VS30 model for South Korea to combine nationwide dense borehole measurements with ambient seismic noise analysis
<p>The average shear-wave velocity within the top 30 m from the surface, V<sub>S30</sub>, represents site characteristics including the soil classification and site amplification that are essential information for building codes and seismic design. A novel method to determine a V<sub>S30</sub> model based on a composite analysis of borehole standard penetration test numbers (SPT N) and horizontal-to-vertical (H/V) spectral ambient noise ratios is introduced. A national V<sub>S30</sub> model for South Korea is determined using the method. The shear-wave velocity structures beneath 20 nationwide broadband seismic stations are determined using the H/V analysis. The SPT N data are collected from 175,619 nationwide densely-distributed boreholes. The shear-wave velocity models from SPT N values are calibrated for the local reference velocity models from H/V analysis. A representative relationship between the SPT N values and shear-wave velocities is introduced. A national V<sub>S30</sub> model for South Korea is determined using the calibrated SPT N models at the nationwide boreholes. The V<sub>S30</sub> model is verified by comparisons with local field measurements. The proposed model is consistent with the USGS model based on a surface slope analysis. The V<sub>S30</sub> structure presents high correlation with geological and topographic features. The V<sub>S30</sub> values are low in coastal (low topographic) areas, and high in mountain (high topographic) areas. Apparent linear relationship is observed between V<sub>S30</sub> and topography. The western and southeastern coastal regions may be vulnerable to strong seismic shaking.</p>
