abstract = "The Southern Brazilian Continental Shelf (SBCS) is one of the more
productive areas for fisheries in Brazilian waters. The water
masses and the dynamical processes of the region present a very
seasonal behavior that imprint strong effects in the ecosystem and
the weather of the area and its vicinity. This paper makes use of
the Regional Ocean Modeling System (ROMS) for studying the water
mass distribution and circulation variability in the SBCS during
the year of 2012. Model outputs were compared to in situ,
historical observations and to satellite data. The model was able
to reproduce the main thermohaline characteristics of the waters
dominating the SBCS and the adjacent region. The mixing between
the Subantarctic Shelf Water and the Subtropical Shelf Water,
known as the Subtropical Shelf Front (STSF), presented a clear
seasonal change in volume. As a consequence of the mixing and of
the seasonal oscillation of the STSF position, the stability of
the water column inside the SBCS also changes seasonally. Current
velocities and associated transports estimated for the Brazil
Current (BC) and for the Brazilian Coastal Current (BCC) agree
with previous measurements and estimates, stressing the fact that
the opposite flow of the BCC occurring during winter in the study
region is about 2 orders of magnitude smaller than that of the BC.
Seasonal maps of simulated Mean Kinetic Energy and Eddy Kinetic
Energy demonstrate the known behavior of the BC and stressed the
importance of the mean coastal flow off Argentina throughout the
year.",
