Algal Blooms (IMAGE) U.S. National Science Foundation Caption An algal bloom is a rapid increase or accumulation in the population of algae in a water system. This type of bloom threatens ecosystems in bodies of water that many people rely upon for survival. A team of Perimeter College students seeks to address this problem through the development of an autonomous algal skimmer using technology similar to the iRobot Roomba vacuum cleaner.
