Bone mineral density & hand x-ray cortical percentages in females
<p>This data set serves as a resource for correlating hand x-rays with bone mineral density (BMD) scans taken within one year of one another. The need for increased methods of screening for low BMD is needed. Therefore, we used this dataset to determine if hand and wrist x-rays could be used to screen for forearm osteopenia and osteoporosis. </p>

X-ray diffraction (XRD) measurement of bulk and clay mineral composition at India National Gas Hydrate Program 01 (NGHP-01) Sites on the Indian continental margin (Krishna-Godavari Basin, Kerala-Konkan Basin, Mahanadi Basin, Andaman Sea)
<p>This dataset contains bulk and clay mineral relative abundances measured by X-ray diffraction (XRD) measured at 12 offshore sites drilled and cored during the Indian National Gas Hydrate Program 01 (NGHP-01) in 2006 by the JOIDES Resolution. Sediment samples from from the Kerala-Konkan Basin, Arabian Sea (Hole 01A), the Krishna-Godavari Basin, Bay of Bengal (Holes 03B, 05C, 07BD, 10BD, 14A, 15A, 16A, 20AB), the Andaman Sea (Hole 17A), and the Mahanadi Basin, Bay of Bengal (Holes 18A, 19A) were measured for bulk and clay XRD at the University of Missouri using a Scintag Pad V X-ray diffractometer.</p> <p>These sites are between 895 and 2663 m of water depth and were from drilled to depths between 172 and 675 m below seafloor. These data were published in:</p> <p><strong>Phillips, S.C., Johnson, J.E., Underwood, M.B., Guo, J., Giosan, L., and Rose, K., 2014.

Four-component relative abundances (total clay, quartz, feldspar, calcite) of bulk sediment powders were calculated using a singular value decomposition (Fisher and Underwood, 1995). Clay fractions were prepared using the filter peel method and 0.45-mm membranes, and saturated with ethylene glycol (Moore and Reynolds, 1997). Clay mineral relative abundances (illite, smectite, kaolinite, chlorite) were calculated using the method of Biscaye (1965) for comparison with previously measured studies from the Indian Ocean.
