National Phytoplankton Monitoring Network (PMN)

NOAA National Centers for Coastal Ocean Science sponsors the Phytoplankton Monitoring Network (PMN) which is a community-based network of volunteers monitoring marine phytoplankton and harmful algal blooms (HABs). PCWW received on-line training on how to collect samples, identify species of fresh water phytoplankton using digital microscopy, and how to report data to the Marine Biotoxins Program.  

PMN monitors 5 freshwater cyanobacteria (blue-green algae) belonging to the Division Cyanophyta and Class Cyanophyceae. A PMN image Gallery is posted online and NCCOS suports an iphone app, titled Phyto. In 2020 we observed small quantities <5% of bacteria in our water samples.
