Hi all,
I wanted to share an update on the H2S experiment we are getting together here in the SF Bay Area. First of all, re: location. There appear to be 2 good possibilities for larger salt marshes, the Don Edwards National Wildlife Refuge and the Palo Alto Baylands. Gwen and I visited Don Edwards a few days ago, in certain areas the smell of sulpher is so intense it's almost sickening, and is just by the road. At Don Edwards, getting cleared for access beyond 'Marshlands Road' is apparently a hurdle, but at the very least we could probably set up canisters along the road without any problem.
I've also had the good fortune to be in touch with a postdoc at Stanford, who has offered to help out finding a good location and gaining access. She advises that the Palo Alto Baylands is much easier to get a permit to run a study in, much smaller so easier to manage, and also she'd done a 5 year study in an area there where they do know the sediments (at least) contain H2S. She also advised that the notion of a 'collapsed' salt marsh isn't one she is familiar with, that instead they mostly all are stinky to some degree. I'm still a bit new to the biogeochemistry, but either way it seems like this will be a good experiment on an environmental source of H2S. There's a definitely certain areas that smell much more strongly of sulpher than others, but others would have to speak to the reason until I can read more.
So the pieces are coming together to run the experiment, and if things continue to go well we hope to run it in the next couple of weeks. I've attached a simple KML with both locations to give an idea of what we are looking at. Also a couple of photos from Marsh Road in Don Edwards. More updates to follow.. I'll also post this as a research note.

So one problem that's come up with the proposal of running our experiment at the Palo Alto Baylands is that if we want to do a balloon or kite map, it apparently has to be cleared with air control - because there are many nearby airports. Any thoughts on this would be appreciated. It sounds like even researchers at Stanford have a lot of trouble getting permission to do this at this location. Ideas?

-- near an airport , more restrictions than the usual below 500' and <6'
come into play.
I'm traveling now but feel free to call 336-269-1539

Hey Matthew, are you doing this mapping in relation to the H2S test? If so,
Scott and I were thinking when we did the test that flying really low,
maybe 50', would be more appropriate for mapping where we laid the test
canisters out. If this thread isn't in relation to H2S then disregard :)

Yes! This is about the H2S tests we'll be running in Palo Alto.
I think, if we can get permission to fly, we'd really like to get images from higher up than that. If everything works out in the experiment we'll have geolocated ground images (from our Rhus app) of exactly where each canister was placed in addition to the aerial map!
