Lake ecosystems and the services that they provide to people are profoundly influenced by
dissolved organic matter derived from terrestrial plant tissues. These terrestrial dissolved …

Terrestrial carbon export via inland aquatic systems is a key process in the global carbon
cycle. It includes loss of carbon to the atmosphere via outgassing from rivers, lakes, or …

The spatiotemporal variability of lake partial carbon dioxide pressure (pCO 2) introduces
uncertainty into CO 2 flux estimates at the lake water-air interface. Knowing the variation …

Browning of surface waters because of increasing terrestrial dissolved organic carbon (OC)
concentrations is a concern for drinking water providers and can impact land carbon …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

We explore the role of lakes in carbon cycling and global climate, examine the mechanisms
influencing carbon pools and transformations in lakes, and discuss how the metabolism of …

Natural lakes are thought to be globally important sources of greenhouse gases (CO2, CH4,
and N2O) to the atmosphere although nearly no data have been previously reported from …

One of the major impediments to the integration of lentic ecosystems into global
environmental analyses has been fragmentary data on the extent and size distribution of …

Lake sediments are “hot spots” of methane production in the landscape. However, regional
and global lake methane emissions, contributing to the greenhouse effect, are poorly known …

Recent results continue to show the general consensus that ozone-related increases in UV-
B radiation can negatively influence many aquatic species and aquatic ecosystems (eg …
