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.

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).

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 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
Download or read book Marine Algal Bloom Characteristics Causes and Climate Change Impacts written by Santosh Kumar Sarkar and published by Springer. This book was released on 2018-05-02 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.
Download or read book Climate change Unpacking the burden on food safety written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-03-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.

Download or read book Emerging Marine Biotoxins written by Ana Gago-Mart´ınez and published by MDPI. This book was released on 2019-08-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of marine and freshwater toxins in geographical areas where they have never been reported before is a concern due to the considerable impact on (sea)food contamination, and consequently, on public health. Several groups of marine biotoxins, in particular tetrodotoxins, ciguatoxins, and palytoxins, are included among the relevant marine biotoxins that have recently emerged in several coastal areas. A similar situation has been observed in freshwater, where cyanobacterial toxins, such as microcystins, could end up in unexpected areas such as the estuaries where shellfish are cultivated. Climate change and the increased availability of nutrients have been considered as the key factors in the expansion of all of these toxins into new areas; however, this could also be due to more intense biological invasions, more sensitive analytical methods, or perhaps even an increased scientific interest in these natural contaminations. The incidences of human intoxications due to the consumption of seafood contaminated with these toxins have made their study an important task to accomplish in order to protect human health. This Special Issue has a focus on a wide variety of emerging biotoxin classes and techniques to identify and quantify them.
