A “red tide” of blooming algae (the dinoflagellate Noctiluca scintillans) stretched more than 20 miles along the coast near LaJolla, California, in spring 1995. Such massive blooms can harm human health, coastal economies, and marine ecosystems. Algal blooms occur naturally, but have become much more common in recent years, some due to human activities that put excess nutrients into the water.
