abstract = "The discovery and subsequent mapping of an ancient shoreline at
25m depth in N-E Brazil by TM-Landsat imagery is described. The
study area is located on a tectonically stable part of the
Brazilian shelf which presently shows a minor uplift rate of 02mm
year , to the north of Natal in the State of Rio Grande do Norte.
This submerged shoreline is characterized by the occurrence of a
large number of long beachrock outcrops (>3Km in length), observed
by diving, which are comparable to their analogues seen on the
present-day beaches of the adjacent coast. The good state of
preservation of this shoreline and the large number of carbonate
rock 'reefs' on it suggest abruptness of a return to transgressive
sea-level relating to the 11000-9000 yr B.P. band. By reviewing
high resolution paleoclimatic data from this period, we conjecture
that this stillstand could be a consequence of the Younger Dryas
cold event in the north Atlantic, which might have also had
importance as a driving morphogenetic process for coasts in a
global scale.",
