Reflectance spectra were also measured for a suite of 60 samples of known mineralogy, thereby providing a local ground-truth calibration of spectral features to percentages of calcite, opal, smectite, and illite. The associated algorithm was used to calculate mineral percentages from the 1343 spectra. Using multiple regression and VNIS mineralogy, multisensor track physical properties and light spectroscopy data were then converted into continuous high-resolution mineralogy logs.completedOceanographyalgorithmsclay mineralogyclay mineralscoresEquatorial Pacifichigh-resolution methodsLeg 199marine sedimentsmathematical modelsmineral compositionnear-infrared spectraOcean Drilling Programoptical spectraPacific Oceanphysical propertiesreflectancesedimentssheet silicatessilicatesspectraurn:org.iodp:exp:199urnlargerWorkCitationcampaignEnglishgeoscientificInformation-148.0000-135.00007.450026.0500Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/199_SR/VOLUME/CHAPTERS/203.PDFdownload
