NOAA is announcing $15.2M in funding for harmful algal bloom (HAB) research projects throughout U.S. coastal and Great Lakes waters. HABs can produce toxins or cause other harmful effects that can damage ecosystems, disrupt our seafood supply, impact economies, and threaten human health. Marine and fresh waters of the United States are increasingly impacted by HABs with blooms reported in nearly every state. They cause annual economic losses up to $100 million on average and costs from a single major HAB event can reach tens of millions of dollars. Investments in these projects represent a coordinated effort within the National Ocean Service to advance our nation's ability to observe, monitor, forecast, and manage blooms.
