Harmful algal blooms challenge ecosystems, food security

Read the full story in Environmental Factor.

Climate change and warming waters are activating two massive seedbeds of a harmful algal bloom (HAB) species called Alexandrium catenella in the Alaskan Arctic, according to NIEHS-funded researcher Donald Anderson, Ph.D. He is a senior scientist with the Woods Hole Oceanographic Institution (WHOI), where he directs the U.S. National Office for Harmful Algal Blooms. Such blooms include overgrowths of toxic algae that can negatively affect human health, disrupt ecosystems, and threaten food security.

Environmental Factor recently spoke with Anderson to learn more about his latest research — published Oct. 12 in the Proceedings of the National Academy of Sciences — and what he and other scientists are doing to address HABs and their potential human health effects.
