Abstract:

Model output of circulation, water mass and dynamical properties (currents, temperature, salinity, and sea level) for the Mississippi Bight and Mississippi Sound region of the northern Gulf of Mexico. The model application is newly developed as part of the GOMRI-funded CONCORDE consortium and has been configured with 400 m spatial resolution and 24 vertical layers. Surface atmospheric forcing is from a 1 km hourly product that resolves the diurnal sea breeze, which was also developed as part of the CONCORDE consortium’s modeling component (the CONCORDE Meteorological Analysis - CMA). Observed freshwater input derived from available tide gauge stations are applied as rivering forcing, and the Naval Research Laboratory-Navy Coastal Ocean Model (NRL-NCOM) output at 1km was used as outer boundary condition forcing. The model output provided in this dataset provides hourly resolution of physical parameters (currents, temperature, salinity, water levels) for the time frame around the Fall 2015 sampling campaign of the CONCORDE observational teams (1 October - 11 November 2015). Other related data from 2016 are available under GRIIDC Unique Dataset Identifiers (UDIs) R4.x260.000:0103 (DOI: 10.7266/N7ZP44QK), R4.x260.000:0104 (DOI: 10.7266/N7P55M4G), and R4.x260.206:0003 (DOI: 10.7266/N7125R1V).

Purpose:

The model output for this time frame from the CONCORDE synthetic model have been generated with the explicit purpose of providing environmental context to support the interpretation of the ship-based field measurements obtained during the Spring field campaign of the CONCORDE consortium.
