In Chesapeake Bay, two species of algae growing threat to ecosystems and communities

Aerial view of a Chesapeake Bay landscape with swirling dark patterns in the water indicated algal blooms. Lush green coastline, scattered houses, and distant forests under a blue sky.Harmful algal blooms (HABs) are fast-growing algae that can produce toxins, harm marine life, and affect public health. In Chesapeake Bay, two species—Alexandrium monilatum and Margalefidinium—pose a growing threat to ecosystems and communities.

NOAA and partners are working to change that. Learn how: https://coastalscience.noaa.gov/project/developing-a-chesapeake-bay-hab-monitoring-and-forecast-system-for-margalefidinium-and-alexandrium-blooms/
