; and (V) in subparagraph (E), as redesignated by subclause (II), by striking hypoxia modeling and monitoring data and inserting hypoxia modeling, forecasting, and monitoring and observation data ; and (E) by adding at the end the following: (c) Action Strategy and scientific assessment for marine and freshwater harmful algal blooms (1) In general Not less frequently than once every 5 years, the Task Force shall complete and submit to Congress an action strategy for harmful algal blooms in the United States. (2) Elements Each Action Strategy shall— (A) examine, and include a scientific assessment of, marine and freshwater harmful algal blooms, including such blooms— (i) in the Great Lakes and upper reaches of estuaries; (ii) in freshwater lakes and rivers; and (iii) that originate in freshwater lakes or rivers and migrate to coastal waters; (B) examine the causes, ecological consequences, and economic or socio-cultural impacts, including food safety and security, of harmful algal blooms; (C) examine the effect of other environmental stressors on harmful algal blooms; (D) examine potential methods to prevent, control, and mitigate harmful algal blooms and the potential ecological, social, cultural, and economic costs and benefits of such methods; (E) identify priorities for research needed to advance techniques and technologies to detect, predict, monitor, respond to, and minimize the occurrence, duration, and severity of harmful algal blooms, including recommendations to eliminate significant gaps in harmful algal bloom forecasting, monitoring, and observation data; (F) evaluate progress made by, and the needs of, activities and actions of the Task Force to prevent, control, and mitigate harmful algal blooms; (G) identify ways to improve coordination and prevent unnecessary duplication of effort among Federal agencies with respect to research on harmful algal blooms
