Cyanobacteria - Cyanobacteria are aquatic bacteria, and are some of the oldest living organelles on Earth.

State of the Beach

2010-Coastal-States.gif

The Surfrider Foundation State of the Beach report is our continually-updated assessment of the health of our nation’s beaches. It is intended to empower concerned citizens and coastal managers by giving them the information needed to take action. For over ten years we have been collecting information on beach access, surf zone water quality, beach erosion, beach fill, shoreline structures, beach ecology and surfing areas to get an understanding of the condition of our nation’s beaches and the effectiveness of programs and policies designed to protect them.
