-Harmful Algal Blooms (HABs) pose an enormous threat to U.S. marine habitation and economy in coastal waters. Federal and state coastal administrators have been working in devising a state-of-the-art monitoring and forecasting system for these HAB events. These modernized HAB systems provide useful and forewarning information to a varied user community. The current approaches are based on optic...

There is growing evidence that the spatial and temporal incidence of harmful algal blooms is increasing, posing potential risks to human health and ecosystem sustainability. Currently there are no US Federal guidelines, Water Quality Criteria and Standards, or regulations concerning the management of harmful algal blooms. Algal blooms in freshwater are predominantly cyanobacteria, some of which...

Toxic compounds are frequently, but not universally, associated with alg,al blooms. Several dinoflagellate and diatom species are capable of toxin synthesis. Some bacteria are also capable of synthesizing at least one family of “algal” toxins. Previous work on algal toxins can be broadly grouped in four categories: observations on the variability in toxin production by single species or among s...

The microstructure of a Cu-0.1%Cr-0.1%Zr alloy after annealing or aging and equal channel angular pressing with conform (ECAP-C) process was investigated. ECAP-C led to formation strain induced low-angle boundaries (LAB) which transformed in high-angle (HAB) during deformation. Deformation microbands developed 1 pass, leading new ultrafine grain the upon further processing. Average size gradual...
