Name SubClassOf URL Description
Project schema:ResearchProject http://opencoredata.org/voc/csdco/v1/Project a collection of activities for a defined scientific goal and funded by the same source; can include expeditions, sample collection, new analyses of existing samples, or others
Borehole csdco:Borehole http://opencoredata.org/voc/csdco/v1/Borehole
Metadata dcat:Dataset http://opencoredata.org/voc/csdco/v1/Metadata
DtubeMetadata dcat:Dataset http://opencoredata.org/voc/csdco/v1/DtubeMetadata
SRF dcat:Dataset http://opencoredata.org/voc/csdco/v1/SRF Locations and information about samples that have been pulled from the cores.
CML dcat:Dataset http://opencoredata.org/voc/csdco/v1/CML Session file in XML format from Corelyzer software defining layout and position of cores and datasets; simplifies setup of project datasets in Corelyzer. The session file references the location of project core image files and numerical datafiles but does not include them in the session file, so file locations must be updated in the session file using a text editor for use on a new user's computer. Data files (.xml format) typically include Geotek MSCL-S and Geotek MSCL-XYZ data. Additional data such as XRF, loss-on ignition or other data sets may be included.
Car dcat:Dataset http://opencoredata.org/voc/csdco/v1/Car Packaged file generated by Corelyzer software that contains all core images and data for the project, allowing simplest setup of project datasets in Corelyzer. Data typically include Geotek MSCL-S and Geotek MSCL-XYZ data. Occasionally data from the scanning XRF, sample locations or other sources are included.
Image dcat:Dataset http://opencoredata.org/voc/csdco/v1/Image The Geotek MSCL-CIS (Core Imaging System) collects ultra high resolution images of core samples with a digital linescan camera. The light and camera lens have polarizing filters to reduce glare on the core surface in the image. Images resolution is specified by the user (25 to 100 micron pixel size, typically 50 micron).
RGBData dcat:Dataset http://opencoredata.org/voc/csdco/v1/RGBData RGB color profiles from a strip through the middle of each core image generated by the MSCL-CIS.
WholeCoreData dcat:Dataset http://opencoredata.org/voc/csdco/v1/WholeCoreData Geotek’s MSCL-S (standard multi sensor core logger) collects geophysical data along the length of the core using a suite of sensors. The parameters measured include P-wave velocity, gamma density, magnetic susceptibility, electrical resitivity, natural gamma. The core sections are pushed through the suite of sensors at a specified interval (typically 0.5 cm) and the core is scanned as it passes. The instrument can be configured to log whole or split cores. Core diameter can range from 5 to 15 cm with lengths up to 155 cm.
SplitCoreData dcat:Dataset http://opencoredata.org/voc/csdco/v1/SplitCoreData The Geotek MSCL-XYZ takes measurements along the split core surface by lowering sensors to the core. The XYZ measures high resolution magnetic susceptibility using a Bartington MS2E point sensor. Color reflectance data are collected using a Minolta CM-2600d color spectrophotometer. These measurements are collected at a specified interval (typically 0.5 cm). Up to 9 cores can be loaded at once, allowing for cores to be run unattended sequentially.
ICDFiles dcat:Dataset http://opencoredata.org/voc/csdco/v1/ICDFiles PSICAT is a software application for lithologic descriptions of cores using a set of controlled vocabularies and patterns for lithologies. The PSICAT folders contain reduced core images, .xml files with core description notes.
LOI dcat:Dataset http://opencoredata.org/voc/csdco/v1/LOI Water, organic matter, carbonate mineral, and siliciclastic+diatom content are estimated by sequentially measuring weight loss in sediment core subsamples after heating at selected temperatures.
Coulometry dcat:Dataset http://opencoredata.org/voc/csdco/v1/Coulometry Carbon coulometry measures the amount of carbon contained in lake sediments, either of organic or inorganic orgin, and thus allows one to examine changes in the chemical makeup of lake sediments through time. The carbon content of sediments can be related to a number of factors such as rates of decomposition, productivity, and/or precipitation of carbonate minerals. The LRC CO2 Coulometer can be used to rapidly determine carbon content from water, gas, or sediment samples.
XRF dcat:Dataset http://opencoredata.org/voc/csdco/v1/XRF Nondestructive analysis for concentrations of most elements from aluminum (atomic number 13) to uranium (92). Stratigraphic resolutions to 0.2mm are possible. Dwell time per sample point ranges from 1 second for abundant elements to 2 minutes for trace elements. Typical scans are at 5 or 10mm stratigraphic resolution and 10 to 15 seconds per sample point.
Grainsize dcat:Dataset http://opencoredata.org/voc/csdco/v1/Grainsize Measures the particle size distribution of sediment samples using laser diffraction analysis
XRD dcat:Dataset http://opencoredata.org/voc/csdco/v1/XRD Routine XRD-mineralogy profiles can provide qualitative and semiquantitative records of shifts in the source of sedimentary components to a lake sequence. XRD mainly displays information on autocthonous and authigenic minerals, but can give some indication of the abundance of amorphous silica phases. Set up with routine data collection, XRD is a rapid, accurate technique which can process 40 samples per day using an automated sample changer.
Charcoal dcat:Dataset http://opencoredata.org/voc/csdco/v1/Charcoal Sediment samples are treated with hydrogen peroxide to destroy most organic matter, leaving charcoal intact. Samples are passed through a 125 µm sieve and the >125 µm fraction is kept, dried onto a petri dish, and counted.
Radiographs dcat:Dataset http://opencoredata.org/voc/csdco/v1/Radiographs Digital X-radiographic images at 16-bit grayscale density and 0.2mm resolution.
