Hi, David - exciting possibilities. Is there a place where blooms may be more common so you can do a proof of concept? Great to see you using Infragram.org - when are your next tests going to be?

Hi Jeff,

Sorry I was away from internet for a while and just seeing this. The place where we were trying is generally a pretty good place to look for blooms but they have been slow to show up this summer. I'm told by a colleague that there might be something on the river now. But if I can't find anything, I may go to a nearby lake to see if I can get something a little more easily. In any case, I plan to do a lot more on this next summer.

Thanks!

• David...

Well, when the time comes, i'm happy to help you connect with others in the area who are using multispectral photography; there's a Boston-area mailing list as well.

interested. i have a pal who works at Stennis space center looking at ocean color, and she was v interested in infragram. She will be going on a cruise this summer to calibrate her sensing algorithim at the sea surface.

David,
Did you see this note about the potential to indicate the presence of cyanobacteria using the difference between NDVI made with infrablue and super-red filters? It might make it possible to confirm that certain types of cyanobacteria are present.

Hi wow! Hadn't noticed all of this activity; thanks for the great ideas and links. I'm hoping to do more of this over the summer and would be happy to talk over some ideas if people are interested in trying stuff together!

That'd be great - perhaps we could coordinate some kind of public outdoor activity. Are you on the boston discussion list? http://publiclab.org/lists

Ah oops, i'd already linked to it! Sorry!

David, I'm wanting to explore using this technology down in Nashville TN to monitor algae blooms. It's still completely brand new to me but I'd love to chat with someone who's done it for some pointers.
