Research on carbon gas flux to and from inland waters has increased over the past two
decades, driven mainly by the need to understand (1) the global carbon budget in regard to …

During a 2016 field expedition to the West Greenland Ice Sheet, a striking observation of
significantly elevated CH4 concentrations of up to 15 times the background atmospheric …

Recent studies have observed high methane concentrations in runoff water and the ambient
air at various glacier sites, including the Greenland Ice Sheet, the glacier forefield in …

Methane (CH4) and carbon dioxide (CO2) are the two most important greenhouse gases
(GHGs). To examine the variation characteristics of Ch4 and CO2 in the coastal South China …

Despite most lakes in the Arctic being perennially or seasonally frozen for at least 40% of the
year, little is known about microbial communities and nutrient cycling under ice cover. We …

Recent observations suggest that karst landscapes may be an unaccounted sink for
atmospheric CH 4, but questions remain about the processes contributing to sub …

Methane is a powerful greenhouse gas that has both natural and anthropogenic sources.
The ability to measure methane using an integrated path length approach such as an …

The accurate measurement of greenhouse gas emissions is a challenge for atmospheric
science. Long-range open-path sensors are flexible enough to be applied to a variety of …

We surveyed 15 lakes during the growing season of 2014 in Arctic lakes of southwest
Greenland to determine which factors influence methane concentrations in these systems …

Small lakes in northern latitudes represent a significant source of CH 4 to the atmosphere
that is predicted to increase with warming in the Arctic. Yet, whole-lake CH 4 budgets are …
