Spectral reflectance data have been used so far for mineral composition studies as well as for lithostratigraphic correlation between sites (Balsam and Deaton, 1991; Balsam et al., 1997; Mix et al., 1995; Ortiz et al., 1999). Their results demonstrate that spectrophotometry can estimate CaCO3 content by using the 4.65-, 5.25-, and 5.55-mu m wavelength spectrums. A detailed overview of various other noninvasive methods is given in Ortiz and Rack (1999). The purpose of this study is to test whether spectrophotometry in the visible band can be used as a tool to gather further information about grain-size variation, sorting, compaction, and porosity, which are directly linked to the sedimentation process. From remote sensing data analyses, it is known that diffuse spectral reflectance data in the visible band in the wavelength window of 7.0-6.5 mu m are sensitive to grain-size variations. It appears that a relationship between grain size and signal absorption exists only in this wavelength window. (e.g., Clark, 1999; Gaffey, 1986; Gaffey et al., 1993). Variations in grain size during a sedimentation process are linked to depositional energy, which affects sorting, compaction, and porosity of sediment deposits. As an example, we study here the spectrophotometric data of the sedimentary sequence of Hole 1098C, which was deposited under widely varying environmental conditions. Alternating turbidite and finely laminated sediments were recovered from Hole 1098C. The turbidites are related to a high depositional energy environment; the finely laminated sediments are related to a low depositional energy environment. Data from Hole 1098C were therefore used to test whether the spectral reflectance data can provide a proxy for these different depositional environments.completedOceanographyAntarctic OceanAntarctic PeninsulaAntarcticacompactioncoresexperimental studiesgrain sizelaboratory studieslaminationsLeg 178marine sedimentsmineral compositionOcean Drilling Programocean floorsODP Site 1095ODP Site 1096ODP Site 1098ODP Site 1099ODP Site 1101Palmer Deepphotometryphysical propertiesplanar bedding structuresporosityreflectancesedimentary structuressedimentssortingspectravariationsurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1095urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1096urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1098urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1099urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1101urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignEnglishgeoscientificInformation-78.2916-64.1228-67.3401-64.2220Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTML; access date Feb. 24, 2002application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/178_SR/VOLUME/CHAPTERS/SR178_21.PDFdownload
