About MV CYANO
MV CYANO is a collaborative initiative among Island Boards of Health and scientists from Great Pond Foundation to monitor cyanobacteria on Martha’s Vineyard.
Cyanobacteria, a.k.a. blue-green algae, are a group of microorganisms found in all Vineyard waters. When cyanobacteria grow rapidly or bloom, they can produce cyanotoxins, which when concentrated, can cause adverse health effects in humans, pets, or livestock who wade in or ingest blooming waters.
