This book was released on 2015 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The NOAA National Ocean Service’s (NOS) Northern Gulf of Mexico Operational Forecast System (NGOFS) has been operational since April 2012 using the Finite Volume Coastal Ocean Model (FVCOM) (Chen et al., 2007) as the core hydrodynamic model. Designed as a regional scale system, NGOFS lacks sufficient spatial coverage and/or resolution to fully resolve hydrodynamic features in critical ports and estuaries [i.e., where NOS Physical Oceanographic Real-Time Systems (PORTS) exist in the region] including Lake Charles, Sabine Neches, Houston/Galveston Bay, Mobile Bay, Pascagola and Morgan City areas. To overcome this shortcoming and better support the needs for marine navigation, emergency response, and effective environmental management, NOS has developed two FVCOM-based, high-resolution, estuary-scale nested forecast models, namely the Northwest and Northeast Gulf Of Mexico Operational Forecast Systems (NWGOFS and NEGOFS). NWGOFS and NEGOFS are coupled with NGOFS through one-way nesting, i.e., NGOFS produces the open ocean boundary forcing (water levels and currents) for NWGOFS and NEGOFS without receiving feedback from the latter. The unstructured model grid was constructed and populated with bathymetry obtained from NOS hydrographic survey soundings and U.S. Army Corps of Engineers survey data. NWGOFS and NEGOFS were calibrated and evaluated with observed data obtained from various government agencies and private companies. The two high-resolution model systems became operational September 2014"--Executive Summary.

Download or read book Understanding and Predicting the Gulf of Mexico Loop Current written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-05-23 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most significant, energetic, yet not well understood, oceanographic features in the Americas is the Gulf of Mexico Loop Current System (LCS), consisting of the Loop Current (LC) and the Loop Current Eddies (LCEs) it sheds. Understanding the dynamics of the LCS is fundamental to understanding the Gulf of Mexico's full oceanographic system, and vice versa. Hurricane intensity, offshore safety, harmful algal blooms, oil spill response, the entire Gulf food chain, shallow water nutrient supply, the fishing industry, tourism, and the Gulf Coast economy are all affected by the position, strength, and structure of the LC and associated eddies. This report recommends a strategy for addressing the key gaps in general understanding of LCS processes, in order to instigate a significant improvement in predicting LC/LCE position, evolving structure, extent, and speed, which will increase overall understanding of Gulf of Mexico circulation and to promote safe oil and gas operations and disaster response in the Gulf of Mexico. This strategy includes advice on how to design a long-term observational campaign and complementary data assimilation and numerical modeling efforts.

This book was released on 2006 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: "On October 1, 2004, a harmful algal bloom forecast system for the Gulf of Mexico was successfully transitioned from research to operational status, creating the Gulf of Mexico Harmful Algal Bloom Operational Forecast System (GOM HAB-OFS). During the following 52 week period 114 operational bulletins, containing 131 bloom forecasts, were disseminated to coastal resource managers, state and federal officials, and academic and research institutions. Two harmful and two non-harmful blooms were accurately identified by HAB forecasters and confirmed by in situ sampling. Bulletin utilization was confirmed for 90% of the total operational weeks and 78% of the total bulletins disseminated. 33 high priority bulletins containing pertinent information due to new bloom appearance or significant change in bloom location or intensity were disseminated with 93% confirmed utilization. In addition to overall utilization of the bulletin, success of the operational bulletins can be broken down into various forecast components to help determine needed enhancements to the system. A coastal impact forecast statement was included in 93% of the total bulletins produced, of which 54% were assessable and 98% of those assessable were confirmed accurate. Bloom transport was included in 83% of all forecasts, of which 66% were assessable and 93% of those assessable were confirmed accurate. Bloom intensification was included in 43% of all forecasts, of which 63% were assessable and 72% of those assessable were confirmed accurate. Change in spatial extent was included in 25% of all forecasts, of which 48% were assessable and 81% of those assessable were confirmed accurate. 90% of the total component forecasts disseminated were confirmed accurate. The results of this assessment will be utilized to enhance the operational forecast system, improving the accuracy of individual forecast components through increased bloom knowledge and advanced technology, as well as exploring additional methods to better assess the accuracy of issued forecasts"--Executive Summary.

This book was released on 2015 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report provides an evaluation of the HAB-OFS products issued for Texas during the bloom years from October 1, 2010 to April 30, 2014, with comparisons to those issued for Florida where possible (Kavanaugh, et al., 2013). A bloom year (BY) refers to the time period from May 1, XXXX to April 30, YYYY, where BY2010-2011 spans the period from May 1, 2010 to April 30, 2011 and so on. This time period was selected to capture the typical initiation and termination period of K. brevis blooms in the Gulf of Mexico, enabling interannual comparisons. The first bloom year only spans from October 1 rather than May 1 because the Texas HAB-OFS was not operational until October 1, 2010. The analysis includes an assessment of bulletin utilization, early warning capability, and forecast quality (i.e. accuracy, reliability, and skill). Previous publications have detailed the technology, models, and procedures that underlie the Texas HAB-OFS (Stumpf, et al., 2003; Tomlinson, et al., 2004; Wynne, Stumpf, Tomlinson, Ransibrahmankul, & Villareal, 2005). The results of this assessment will be used to guide enhancements to the operational forecast system with the goal of improving forecast quality through increased scientific understanding and the refinement of forecast models. Some of the recommendations may also be applicable to the HAB-OFS in the eastern Gulf of Mexico"--Objective (page 2).

Book excerpt: The Naval Research Laboratory (NRL) Oceanography Division has implemented a 1/25 deg horizontal-resolution numerical ocean model for the Gulf of Mexico (GOM). The model domain encompasses the entire GOM extending from 18 deg to 31 deg North and from 77 deg to 98 deg West. The physical formulation is based on the Naval Coastal Ocean Model (NCOM) configured with a 40 level -z vertical structure: 19 terrain-following (sigma) levels at the top of the water column, and 21 z (depth) levels at the bottom. The terrain-following levels, reaching from the surface to about 137 meters, allow higher vertical resolutions for resolving mixed layer/shallow waters, while the z-levels are used in the stratified ocean. The ocean bathymetry is constructed from the NRL 2-minute database with the coastline set at a depth of 2 meters. The physical model is one-way coupled to a 13-component ecosystem (biogeochemical) model [Chai et. al., 2002, 2003, 2007] that includes nutrients, two classes of plankton, as well as O and C02. The current configuration is tailored, but not limited to, real-time (RT) prediction; providing nowcasts (current state of the ocean) and up to 120-hour forecasts for the region. In this configuration, the model receives (initial) boundary information from the operational 1/8 deg Global NCOM, and it is forced by 3-hourly 1/2 deg momentum and heat fluxes from the Naval Operational Global Prediction System (NOGAPS). The NCOMGOM model assimilates daily surface/subsurface temperature and salinity generated by the Modular Ocean Data Assimilation System (MODAS), which regresses satellite derived Sea Surface Temperature (SST) and Sea Surface Height (SSH) data to obtain T & S synthetic profiles.
