This data contains high-resolution XRF data scanned from IODP cores recovered from Expedition 369, IODP Sites U1513, U1514 and U1516. Sietske Batenburg was responsible for scanning the Cenomanian-Turonian interval at Sites U1513 and U1516, and the lower half of the Eocene at U1514. Data is available from IODP database: http://web.iodp.tamu.edu/LORE/
(I) Handpump Vibration Data For each handpump, data is organized in one CSV file per day. These files are grouped together over batches, where each batch approximately corresponds to three months. (II) Borehole Water Level Data Water level data at the borehole of each handpump is recorded in one CSV file per handpump. Both uncompensated (raw) and compensated (with respect to atmospheric pressure) data are available. (III) Data Time Logs A separate Excel file lists the locations of the monitoring sites and the time logs corresponding to both (I) and (II) per handpump. References:  P. Thomson, R. Hope, and T.

The dataset consists of daily rainfall data for 23 manual rain gauge stations installed by Gro for GooD project within and about the study area. The installed stations covering four river catchments name Ramisi River, Mukurumudzi River, Mtawa River and Mwachema River in Kwale County. The dataset period is from January 2016 to November 2018.

Volcanic ash samples were collected and analysed following the 2015 eruption of Calbuco volcano, Chile. Datasets uploaded are: Calbuco2015 Probe Data - excel Calbuco2015 Locations and Grain Size – excel Calbuco Deposit Measurements grl54177-sup-0002-tables3 Published as supplement to A.R. van Eaton et al (2016) Volcanic lightning and plume behavior reveal evolving hazards during the April 2015 eruption of Calbuco volcano, Chile, Geophysical Research Letters 43 (7), 3563-3571 Electron Probe Micro Analysis Major element compositions of plagioclase, groundmass glass and melt inclusions were analysed with a JEOL JXA-8600 wavelength-dispersive electron microprobe (EMP), equipped with four spectrometers, at the Research Laboratory for Archaeology and the History of Art, University of Oxford using a defocused beam (5¿m), low beam current (4nA) and accelerating voltage of 15 kV. Full analytical conditions are detailed in Rawson et al. (2015). Secondary standards used were Gor128-G and StHs/80-G for glass (Jochum et al., 2006). Glass (melt inclusion and groundmass) totals were normalised to 100% to account for variable secondary hydration. Stoichiometry and charge balancing was used to determine the amount of Fe2O3 and FeO in plagioclase. Pyroxene and magnetite grains were analysed with a defocused beam (5¿m), higher beam current (10nA), and an accelerating voltage of 15 kV. Secondary standards used were hornblende (USNM 111356), Pyrope (USNM 1143968) and ilmenite (USNM 96189; (Jarosewich et al., 1980). Stoichiometry and charge balancing was used to determine the amounts of Fe2O3 and FeO, following Droop (1987). Thickness and Grain size analysis Ash fallout thicknesses were measured in the field shortly after deposition, and samples collected for follow-up analysis of grainsize and chemical composition. Grain size analysis was conducted using a Malvern Laser Particle Sizer Mastersizer 2000 at the University of Oxford.

Dataset of material characterisation (X-ray diffraction) analyses to constrain the nature of materials produced during Fe(II)-silicate precipitation experiments from seawater in the presence of various metals.
Geological observations during field walks, with coordinates, photographs and descriptions of rocks/geological materials and features at the various stops.
Here, we provide data corresponding to the experimental conditions used, the results gained via electron microprobe for natural and experimental volcanic samples. Mass balance calculations and a compilation of monitoring data for recent explosive eruptions.
This dataset contains digital terrain data that describes the topography of the area under study at 90m resolution based on SRTM 90m Digital Elevation Data from the CGIAR-CSI (Consultative Group on International Agricultural Research - Consortium for Spatial Information).
