The global carbon cycle connects organic matter (OM) pools in soil, freshwater, and marine
ecosystems with the atmosphere, thereby regulating their size and reactivity. Due to the …

While the sentinel nature of freshwater systems is now well recognized, widespread
integration of freshwater processes and patterns into our understanding of broader climate …

Dissolved organic matter (DOM) is recognized for its importance in freshwater ecosystems,
but historical reliance on DOM quantity rather than indicators of DOM composition has led to …

Rivers integrate processes occurring throughout their watersheds and are therefore
sentinels of change across broad spatial scales. River chemistry also regulates ecosystem …

Permafrost thaw has been widely observed to alter the biogeochemistry of recipient aquatic
ecosystems. However, research from various regions has shown considerable variation in …

In the mostly pristine Congo Basin, agricultural land-use change has intensified in recent
years. One potential and understudied consequence of this deforestation and conversion to …

Climate change is dramatically altering Arctic ecosystems, leading to shifts in the sources,
composition, and eventual fate of riverine dissolved organic matter (DOM) in the Arctic …

Evasion of greenhouse gases (GHG) from fluvial systems is now recognized as a significant
component of the global carbon cycle. However, the magnitudes of GHG fluxes remain …

Arctic warming is causing ancient perennially frozen ground (permafrost) to thaw, resulting
in ground collapse, and resha** of landscapes. This threatens Arctic peoples' …

Hydrological transformations induced by climate warming are causing Arctic annual fluvial
energy to shift from skewed (snowmelt-dominated) to multimodal (snowmelt-and rainfall …
