The algorithm is capable of identifying layer boundaries within sediment profiles, as demonstrated for artificial as well as two field data sets. Layers are detected with a good resolution within (i) digital images of a deep sea sediment core (IODP-expedition 301, core 15H) and (ii) chemical concentration patterns of recent tidal sediments (North Sea).completedSedimentary petrologyalgorithmsalkaline earth metalsaluminumAtlantic Oceanbeddingboundary element analysisboundary layercalciumchemical compositiondeep-sea sedimentationdegradationdensitydigital dataExpedition 301four-dimensional modelsIntegrated Ocean Drilling ProgramIODP Site 1301marine sedimentationmetalsNorth AtlanticNorth Seaplanar bedding structuressedimentary structuressedimentationsedimentssiliconsoil profilestidal flatswaveletsurn:org.iodp:exp:301urnlargerWorkCitationcampaignurn:org.iodp:exp:301:site:U1301urnlargerWorkCitationstudyurn:org.iodp:exp:301urnlargerWorkCitationcampaignEnglishgeoscientificInformation-131.000011.000046.000061.1000North Seaapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www.nonlin-processes-geophys.net/13/661/2006/npg-13-661-2006.pdfdownload
