Understanding phytoplankton health can help predict harmful algal blooms, or HABs. When substances from land wash into the ocean, they sometimes become a feast for algae, allowing them to eat, grow and multiply rapidly. HABs can generate harmful toxins that sicken marine wildlife and humans and deplete oxygen in the water as bacteria feed on numerous dead algae.
