Floodplain margins of Tonle Sap Lake, Cambodia in a late afternoon haze. Coupled CH 4 production and oxidation support CO 2 supersaturation in this tropical flood-pulse lake, and may contribute to high reported CO 2 supersaturation and atmospheric emissions from other tropical freshwaters with large amounts of seasonally or perennially flooded land.

Methane sampling sometimes consists simply of cutting water bottles in half, floating them on the surface of a lake, and measuring the increase in methane over time within the bottle headspace. Such bottles can be seen here on a fishing boat departing from a bustling floating village on Cambodia’s Tonle Sap Lake.
