Florida algal blooms put focus on phosphorus depletion and ultrasonic wave tech

Algal blooms are caused when algae living in seas or freshwater grow uncontrollably because of the presence of nutrients like phosphorus or nitrogen; high temperatures and the underwater penetration of light also play roles in the process. Public health costs, however, are dwarfed by the price tag which algal blooms can put on industries requiring clean water, such as seafood, tourism and restaurants. Every year, harmful algal blooms (HABs), the toxic variety currently seen in Florida, cost about $82 million in lost economic output according to statistics published by the National Oceanic and Atmospheric Administration (NOAA). Last year, algal blooms on the West Coast caused beaches in Washington State to close, preventing razor clamming at an estimated economic cost of $9 million over one month.
