A geography of lake carbon cycling


Carbon cycling in lakes is highly variable among lakes within regions, and across regions and continents, but the underlying causes of this variation among lakes and regions are not well understood. In this essay, we propose two main mechanisms that operate at the regional scale and contribute to broad‐scale interlake variation in carbon cycling. This essay sets the foundation for a geographic understanding of lake carbon cycling, which facilitates developing testable hypotheses to improve estimates of the role of inland waters in global elemental cycles.
