DA %J Anais da Academia Brasileira de Ci¨ēncias %D 2002 %I Academia Brasileira de Ci¨ēncias %X Bathymetric and sedimentological data from water depths between 3 and 28 meters are the basis of a detailed bathymetric map of the Itaip¨˛ Embayment and an understanding of its sedimentary dynamics. Shallower than 16 meters the contours are parallel to the shoreline whereas the morphology of the deeper bottom is influenced by the Menina, M e, and Pai islands. Medium sand is prevalent, with local variations in more protected or less protected areas. Minor amount of black mud possibly derives from the Itaip¨˛ Lagoon. Siliciclastic granules and pebbles may be relict. The Itaip¨˛ Embayment's bottom morphology is controlled by stormy waves and the calmer easternmost part of the embayment presents a tendency to accumulate finer sediments. %K coastal dynamics %K coastal sedimentation %K geomorphology %K quaternary %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652002000100009
