abstract = "A preliminary analysis of a segment of the Paraiba littoral in
northeastern Brazil revealed a prograding shoreline in a coast
currently characterized by estuarine transgressive depositional
systems. Detailed study of coastal geomorphology is of relevance
to reconstruct the sea-level history in this shoreline. Such
investigation can help improve the record of past sea-level curves
of northeastern Brazil, an issue still open to debates. In this
work, we explored remote sensing imagery for the geomorphological
characterization of this prograding shoreline and combined this
information with geological field data aiming to establish the
various phases of shoreline progradation. In addition, we also
analyzed the potential forcing factors responsible for the
morphological changes in the eastern section of the littoral of
Paraiba during the late Holocene, comparing changes with other
prograding shorelines along the east coast of Brazil.
Geomorphological interpretation was based on the analysis of
Phased Array type L-band Synthetic Aperture Radar (PALSAR) images
acquired aboard the Advanced Land Observing Satellite 1 (ALOS-1).
Geological data comprised dating of sand samples by the optically
stimulated luminescence (OSL) technique for the establishment of
the chronological context. The coastal deposits are represented by
a cuspate morphology and numerous internal beach ridges that
prograded seaward from a roughly north-south trending palaeocliff.
The chronological data indicate shoreline progradation during the
past 2.1 +/- 0.1 ka, after the mid-Holocene sea-level fall.
Several prograding episodes occurred during this time, some not
matching with proposed sea-level rises punctuated upon the overall
fall. Together with the regional geological context of the study
area, we propose that eustatic sea-level was not the only factor
triggering coastal progradation in this region.",
