The presentworkhastheobjectiveofcharacterizing marine habitats ofthe continental shelfofbeach Iracema in Fortaleza, Ceara, fromtheintegratedanalysisofthebenthicsubstract. Thischaracterizationwasbasedonthe background bathymetry, sedimentology, andbenthic fauna and flora ofthelandscapefragmentsof data collectedonthe site andanalyzed in thelaboratory. The particlesizeanalyzesonthe 20 fieldsamplesindicated a fractiondistributionofgravel, medium, fine andvery fine sand, andbiogenicfractions. The sandsclass are in isolated spots, with a percentageof 90 to 100%, with some containing mica The mediumsandoccurs in theNWportionofthearea.

The biodiversityhighlightofthebiodiversitywasfound in Station3, wherewerefoundexamplesofthe Echinodermata, Mollusca, Porifera, and Annelida phyla. In thesamplessubstantiallysandy, it wasobservedthepresenceoforganismsbelongingtothephylum Mollusca - Class Bivalvia. The bioticandabiotic data interaction (sedimentologicalandbathymetric) allowedthemappingof four marine habitats, classified in Levels1and 2, codes A (Marine Habitats) and A1 (Littoral Rock andother hard substrata), oftheclassificationproposedbyEUNIS, 2012.
