The larger model domain (parent grid) is centered on Florida
Bay, encompasses the eastern side
of the Loop Current and the Florida Strait all the way to
Cuba to the
south and the Great Bahamas Banks to the East. A zoom (child grid) focuses on Florida
Bay and the Dry Tortugas.
horizontal resolution of the parent grid is 2 km and the minimum depth is 3m.
In the child grid the horizontal resolution is 700 m and the minimum depth 1m. Both models have 25

Assimilation (SODA) reanalysis global
The model uses a weekly or monthly relaxation to the SODA
reanalysis for the period 1995-2005.
Tides were set at the boundaries by the TPXO6 global tide
We will use 4-times daily atmospheric forcing obtained from
theNavy Operational Global
Atmospheric Prediction System (NOGAPS ) and Coupled Ocean
Atmosphere Mesoscale Prediction System (COAMPS). Bulk fluxes capability of the
ROMS model will be used. Wind stress is obtained from QuikSCAT
scatterometer or calculated from
COAMPS surface wind speed.
The simulation is set in
the framework of a Fisheries and the Environment (FATE) project:
of Biological and Physical Indices for Stock Evaluation in the Dry Tortugas
Pink Shrimp Fishery
This 2-yr project involves collaboration between
ecologists, oceanographers, and stock assessment scientists. The project goal is to develop physical and
biological indicators of recruitment to help assess the status of the pink
shrimp stock in south Florida and
better inform fishery managers about the factors contributing to stock changes. Existing hydrodynamic and biophysical models
will be used to develop indices of recruitment of young adult pink shrimp to
the Tortugas, Florida fishery.
The models and physical variables the models identify will provide a basis for
incorporating environmental variability
into stock assessment and fishery management. The pink shrimp (Farfantepenaeus duorarum)
supports a multi-million-dollar fishery in south Florida
and is a major link between the food
web base and top consumers (Browder et al.
2002) and between offshore and coastal ecosystems (Criales
et al. 2005, 2006, 2007). The Regional Ocean Modeling System (ROMS), a
coastal-scale hydrodynamic model, will be the foundation of the coupled model.
In the proposed work, ROMS will connect the lower Florida Shelf with larger
scale flows of the Gulf of Mexico and the western North
Atlantic, while incorporating detailed coastal dynamics around Florida
Bay and the SW Florida Shelf and
the presence of fresh water discharge. Tide, a fundamental factor in transport
of pink shrimp, is an intrinsic element of ROMS missing from other regional
models of the south Florida area.
The Biophysical Lagrangian Model (Paris et al. 2005)
will be coupled to ROMS to predict successful immigration of postlarvae to inshore nursery grounds. This model has been used in other
applications in south Florida and
the wider Caribbean to incorporate behavior into the
larval transport process. Model output
will help identify the most relevant physical and biological parameters
affecting larval transport and recruitment success of pink shrimp. These physical and biological indicators will
be used to develop a recruitment index for use in stock assessment.
