Short summary
Short summary
Peatlands are complex and widespread ecosystems that store large amounts of carbon through photosynthesis. Carbon fixation depends on solar irradiance, and the relationship between them is called the photosynthesis-irradiance or “PI” curve. We developed a simple, portable chamber to measure PI curves in peatlands, taking into account complex plant assemblages and microhabitat variability. This tool may help scientists better understand carbon dynamics in these ecosystems.

Short summary
Short summary
Methane (CH4) seepage is the steady or episodic flow of gaseous hydrocarbons from subsurface reservoirs that has been identified as a significant source of atmospheric CH4. The monitoring of these emissions is important and despite several available methods, large macroseeps are still difficult to measure due to a lack of a lightweight and inexpensive method deployable in remote environments. Here, we report the development of a mobile chamber for measuring intense CH4 macroseepage in lakes.
