Abstract:

The forecast from the Naval Research Laboratory (NRL) Intra-American Seas Nowcast Forecast System (IASNFS) was used to understand the circulation patterns observed during Fall 2007 and determine whether the circulation patterns were favorable for advection of a Karenia brevis bloom first observed in the Florida Panhandle. The velocity components were used to release Lagrangian particles (dataset R4.x260.000:0093) and determine the transport during that time frame. This dataset was downloaded from the EDAC OceanNOMADS webpage (https://www.northerngulfinstitute.org/edac/oceanNomads/IASNFS.php). This dataset is in support of the publication: Soto, I.

Purpose:

To understand the circulation patterns during fall 2007 in the northern Gulf of Mexico and the factors that may or not lead to advection of Karenia brevis blooms.

Data Parameters and Units:

Time (YYYYMMDDHH), Longitude (degrees East), Latitude (degrees North), Depth (m), u-velocity component (m/s), v-velocity component (m/s)

This dataset was downloaded from the EDAC OceanNOMADS webpage (https://www.northerngulfinstitute.org/edac/oceanNomads/IASNFS.php). The information associated with this dataset in the EDAC website is the following: The Naval Research Laboratory (NRL) Intra-American Seas Nowcast Forecast System (IASNFS) provides experimental near-real-time predictions of Gulf of Mexico and Caribbean waters. The IASNFS consists of a 1/24 degree (~6 km), 41-level sigma-z developmental data-assimilating ocean prediction system based on NRL's Navy Coastal Ocean Model (NCOM). The model topography is from NRL DBDB2. For daily nowcast/forecast the model is restarted from previous nowcast. Once the model restarts it continuously assimilates the synthetic temperature/salinity profiles generated by an NRL data analysis Modular Ocean Data Assimilation System (MODAS) to produce the nowcast. Real-time data come from satellite altimeter (GFO, Jason-1, ERS-2) global sea surface height anomaly and AVHRR global sea surface temperature. Three hourly surface heat fluxes, including solar radiation, wind stresses and sea level air pressure from the Navy Operational Global Atmospheric Prediction System (NOGAPS) are applied for surface forcing.
