The ice‐covered period on lakes in the northern hemisphere has often been neglected or
assumed to have less importance relative to the open water season. However, recent …

Background, aim, and scope Dissolved organic matter, measured as dissolved organic
carbon (DOC), is an important component of aquatic ecosystems and of the global carbon …

Collectively, reservoirs created by dams are thought to be an important source of
greenhouse gases (GHGs) to the atmosphere. So far, efforts to quantify, model, and manage …

Freshwaters are important sources of greenhouse gases (GHGs) to the atmosphere that may
partially offset the terrestrial carbon sink. However, current emission estimates from inland …

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 …

Because freshwater covers such a small fraction of the Earth's surface area, inland
freshwater ecosystems (particularly lakes, rivers, and reservoirs) have rarely been …

We show that sediment respiration is one of the key factors contributing to the high CO2
supersaturation in and evasion from Finnish lakes, and evidently also over large areas in the …

Arctic climate change is leading to accelerated melting of permafrost and the mobilization of
soil organic carbon pools that have accumulated over thousands of years. Photochemical …

Shallow fresh water bodies in peat areas are important contributors to greenhouse gas
fluxes to the atmosphere. In this study we determined the magnitude of CH 4 and CO 2 …

This study examines a natural, rapid, fivefold increase in dissolved organic carbon (DOC)
concentrations in a temperate shallow lake, describing the processes by which increased …
