A warming climate is rapidly changing the distribution and exchanges of carbon within high Arctic ecosystems. Few data exist, however, which quantify exchange of both carbon dioxide (CO 2 ) and methane (CH 4 ) between the atmosphere and freshwater systems, or estimate freshwater contributions to tot...
