I was at the Esplanade in Boston, and I noticed something very weird in the water. By the Fairfield St. entrance, the water under the bridge and by the shore (on both sides, river and ‘canal’) was bright green, as if someone had dumped dye or paint in the water. When I got real close and then fished out some of the green water, I noticed that it wasn’t die or paint at all, but tiny (<1mm) algal colonies (I think). I have no idea what kind of algae they were (sorry, I didn't have my dissecting microscope handy). If there are any other Bostonian readers, have you seen this? And whom does one contact about this--both to alert someone and to find out more information?
