One such HAB that's recurring in the coastal waters of New York and New Jersey since mid-1980s, and has been reported in other countries recently, is brown tide bloom. The causal organism is a minute pel agophyte (cell diameter ~- 2 um) Aureococcus anophagefferens. The brown tide bloom has been responsible for the severe ecological damage and economic loss (e.g. shellfishery) in the affected areas. This research focuses on finding a method to control brown tide blooms and explores the potential of natural chemical biocide hydrogen peroxide (H_2O_2) as a reagent to serve the purpose. Studies on laboratory cultures were carried out in order to determine the effectiveness of H_2O_2 at eradicating A. anophagefferens. Then, the safety (to non-target organisms) and selectivity of H_2O_2 treatment was tested by exposing a dozen common marine phytopl ankton species to H_2O_2. This was followed by a study exploring the applicability of H_2O_2 treatment in the field and finally, the effects of algal growth phase and biomass on treatment efficacy were tested. The kinetics of H_2O_2 decomposition were examined in parallel. The dissertation discusses the possible action of H_2O_2 on algal cells based on cell wall structure, cell size, growth phase and algal cell density, factors potentially affecting the treatment efficacy and realistic scenario of H_2O_2 application.","abstract_html":"Harmful algal blooms (HABs) are growing problem across the globe.
