RESTORE Research: Evaluation of Gulf of Mexico oceanographic observation networks, impact assessment on ecosystem management and recommendations: Simulated Current Velocity, Temperature, Salinity, and Elevation from Hydrodynamic Modeling for 2015 (NCEI Accession 0194303)
This dataset is based on archives from the University of Miami’s high-resolution (1/50 degrees, 1.8km) configuration of the Hybrid Coordinate Ocean Model (HYCOM) in the Gulf of Mexico (GoM-HYCOM 1/50) for the year of 2015. The GoM-HYCOM 1/50 used realistic river forcing parameterization with daily river discharge obtained from the Army Corps of Engineers and the U.S. Geological Survey (USGS). Atmospheric forcing was from the European Center for Medium-Range Weather Forecasts (ECMWF) at 0.125-degree spatial resolution and it is nested within a Global HYCOM. The model assimilated satellite observations of sea surface temperature and sea surface height and in situ observations of temperature and salinity. The GOM-HYCOM 1/50 gives details on the fronts and filaments associated with the Mississippi River plume dynamics, as well as GoM mesoscale processes. The dataset includes the surface model fields of temperature, salinity, currents and sea surface height from the GoM-HYCOM 1/50 at 12Z along with two experimental simulations designed to study the effect of river front; Reference, noMR (without Mississippi River), and noMR_noPcip (without Mississippi River and precipitation).

Purpose | The project “Evaluation of Gulf of Mexico oceanographic observation networks, impact assessment on ecosystem management and recommendations” aims at evaluating how oceanographic observations of the Gulf of Mexico can support ecosystem management. This is performed by the combined use of modeling and observations. Our focus area is the Florida Keys, which are influenced by the Gulf of Mexico conditions and host a large National Marine Sanctuary where ecosystem management is essential. The dataset provides a description of the ocean conditions and circulation in the Gulf of Mexico in the year 2015, which was marked by a prolonged episode of long-distance export of brackish waters, from the Northern Gulf to the Gulf interior and to the Straits of Florida. It provides unprecedented details about the surface plumes of brackish waters and their evolution. Two perturbed simulations, in which the Mississippi River discharge and atmospheric precipitation were turned off, allow identifying the sources of the fresh waters present at the surface of the Gulf of Mexico in 2015. As the ocean conditions in the Florida Keys are determined, to a large extent, by the Gulf of Mexico conditions, in particular through the transport of nutrients supplied by river waters, it is important to understand the processes that influence that transport. The long-distance export episode of 2015 is an excellent study case to understand these transport mechanisms. The data in this accession were funde d by the NOAA RESTORE Act Science Program under award NA15NOS4510226 to the University of Miami. |
