FALMOUTH POND COALITION ZOOM WEBINAR
TUESDAY, MAY 19TH, 4:00-5:30PM
 
HARMFUL ALGAL BLOOMS IN FALMOUTH PONDS: WHAT REAL-TIME
MONITORING AND ROOT CAUSE ANALYSIS ARE REVEALING
  PRESENTER: DR. MATT LONG, CHIEF SCIENTIST, SUBTIDAL, INC.

Cape Cod's ponds are under increasing pressure from warming temperatures and nutrient pollution, and harmful algal blooms are becoming more frequent and harder to predict. Using continuous sensor data collected from Subtidal's monitoring buoys in four Cape Cod ponds (two in Falmouth, one in Centerville, one in Marstons Mills) during the 2025 season, we'll walk through what real-time monitoring actually reveals: when and how cyanobacteria blooms develop, how seasonal pond mixing triggers events, and what the data suggests about the underlying causes and fixes — including the role of internal nutrient loading, where a pond's own sediments drive blooms from below. We'll also cover what's planned for the 2026 season and how you can get involved.

About the Presenter
This webinar will be led by Dr. Matt Long, a scientist at the Woods Hole Oceanographic Institution and co-founder and Chief Scientist of Subtidal. With a career spanning aquatic science, physical processes and environmental instrumentation, Matt has spent decades developing the sensors, data systems, and analytical methods needed to understand what's actually happening beneath the surface of our ponds and coastal waters. Through Subtidal, he is bringing that expertise to bear on one of Cape Cod's most pressing environmental challenges — translating continuous, real-time monitoring data into clear answers about why harmful algal blooms happen, and what communities can do about them.
