The Woods Hole Center for Oceans and Human Health (WHCOHH) is a virtual, interdisciplinary center, based at WHOI, that brings together scientists from oceanographic, biological, and technical institutions to cooperatively address issues of human health as they pertain to oceanographic research. The Woods Hole COHH currently specializes in the study of harmful algal blooms, also known as HABs, or red tide. Researchers are examining how climate change is affecting HAB dynamics, human exposure, and human health impacts, as well as how low-level exposure to HAB neurotoxins may affect early development and behavior later in life. Past research has included the genetic and environmental study of other waterborne pathogens that pose a risk to human health. Together, research and communications efforts at the Center are helping to advance our understanding of HABs and inform action to protect human health from their toxic effects.
