The sediments of lakes and reservoirs produce significant amounts of the powerful
greenhouse gas methane (CH 4). Characterizing the rate, timing, and controls on the
transport of CH 4 from sediments is critical for understanding emissions from lacustrine
ecosystems. In this dissertation, we explore environmental and anthropogenic drivers of CH
4 flux from lake sediments at multiple spatiotemporal scales and address several
methodological challenges to measuring CH 4 transport into lake water columns.
