Creative use of Rain Gauge to study Methane Gas In Artic Lake

The guages were installed upside-down at the bottom of an artic lake over sediment that 'burp' methane gases.  In the same way that our rain gauge works with water, the mechanism has shown itself capable of measuring a volume of gas.  An amount of methane released into the inverted rain gauge enters the collection area, proceeds through an inlet to the tipper mechanism which responds to a known volume of gas, tips and creates a count via momentary closure of a dry reed switch.  After responding to the initial gas/tip, the tipper is reloaded and ready for the next known amount.
