Okay,<br>
<br>
I've talked with my collaborator and I'll try to get some
preliminary data out to you all.<br>
<br>
Files will be 2 Gb Mp3 files. We use zoom h4 with some hydrophones
to sample over many days. the zoom makes a new file ever 2 gb so
when running continuously we can get about 24 days without have to
visit the instruments. <br>
<br>
Initial deployment was in a fen in New Hampshire and on a lake in
Sweden. I'll have more next week and the mp3 files.<br>

Ruth Varner</strong> and <strong>Michael Palace</strong> of
CSRC were recently funded by the U.S. Geological Survey to
develop a prototype instrument to detect ebullition or bubbling
events of methane in wetland and lake ecosystems. This novel
method utilizes hydrophones (underwater microphones) to monitor
and extract this information cheaply and efficiently over long
temporal scales. Coupling these audio methods with the analysis
of gas samples will help to determine the pathway by which
methane is formed through microbial processes or methanogenesis.<br>
<br>
I'm wondering if I get these long audio files together if people
might be interested in making a microsound project using them as
source files.<br>
