Abstract:

This project measured the amount of methane present in shallow permafrost and gas hydrate near Fairbanks, Alaska, to evaluate the role of permafrost and gas hydrate as possible sources of atmospheric methane. Air samples and 10 cm core samples were analyzed by gas chromatography.

Purpose:

Scientific Research
