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 and microbial transformation will liberate a fraction of this carbon to the atmosphere in the form of CO2 and CH4. We quantified these fluxes in a series of permafrost thaw ponds in the Canadian Subarctic and Arctic and further investigated how optical properties of the carbon pool, the type of microbial assemblages… 

Methane and carbon dioxide emissions from thermokarst lakes on mineral soils

Thermokarst lakes are known to emit methane (CH4) and carbon dioxide (CO2), but little attention has been given to those formed from the thawing and collapse of lithalsas, ice-rich mineral soil

Emissions from thaw ponds largely offset the carbon sink of northern permafrost wetlands

The importance of small ponds for C fluxes in two permafrost wetland ecosystems in northern Sweden is examined and the need for integrated research linking C cycling on land and in water in order to make correct assessments of contemporary C balances is emphasized.

Carbon dynamics in highly heterotrophic subarctic thaw ponds

Abstract. Global warming has accelerated the formation of permafrost thaw ponds in several subarctic and arctic regions. These ponds are net heterotrophic as evidenced by their greenhouse gas (GHG)

Carbon emission from thermokarst lakes in NE European tundra

Emission of greenhouse gases (GHGs) from inland waters is recognized as highly important and an understudied part of the terrestrial carbon (C) biogeochemical cycle. These emissions are still poorly

Dissolved organic matter photolysis in Canadian arctic thaw ponds

The abundant thaw lakes and ponds in the circumarctic receive a new pool of organic carbon as permafrost peat soils degrade, which can be exposed to significant irradiance that potentially increases

Emission of Greenhouse Gases From Water Tracks Draining Arctic Hillslopes

Experimental and ambient warming of Arctic tundra results in emissions of greenhouse gases to the atmosphere, contributing to a positive feedback to climate warming. Estimates of gas emissions from

Temperature effects on net greenhouse gas production and bacterial communities in arctic thaw ponds.

The increase in experimental GHG production accompanied by changes in community indicates an additional factor to consider in sediment environments when evaluating future climate scenarios.

Year-round CH 4 and CO 2 flux dynamics in two contrasting freshwater ecosystems of the subarctic

Abstract. Lakes and wetlands, common ecosystems of the high northern latitudes, exchange large amounts of the climate-forcing gases methane (CH4) and carbon dioxide (CO2) with the atmosphere. The

Weak mineralization despite strong processing of dissolved organic matter in Eastern Arctic tundra ponds

Permafrost thawing mobilizes large quantities of organic carbon that was sequestered in Arctic regions over the last glacial cycle. Processes involved in the oxidation of this carbon need to be

Winter Accumulation of Methane and its Variable Timing of Release from Thermokarst Lakes in Subarctic Peatlands

Previous studies of thermokarst lakes have drawn attention to the potential for accumulation of CH4 under the ice and its subsequent release in spring; however, such observations have not been



The flux of CO2 and CH4 from lakes and rivers in arctic Alaska

Partial pressures of CO2 and CH4 were measured directly or calculated from pH and alkalinity or DIC measurements for 25 lakes and 4 rivers on the North Slope of Alaska. Nearly all waters were

Vulnerability of Permafrost Carbon to Climate Change: Implications for the Global Carbon Cycle

ABSTRACT Thawing permafrost and the resulting microbial decomposition of previously frozen organic carbon (C) is one of the most significant potential feedbacks from terrestrial ecosystems to the

Methane bubbling from Siberian thaw lakes as a positive feedback to climate warming

It is found that thawing permafrost along lake margins accounts for most of the methane released from the lakes, and it is estimated that an expansion of thaw lakes between 1974 and 2000, which was concurrent with regional warming, increased methane emissions in the study region by 58 per cent.

Effects of permafrost melting on CO2 and CH4 exchange of a poorly drained black spruce lowland

[1] Permafrost melting is occurring in areas of the boreal forest region where large amounts of carbon (C) are stored in organic soils. We measured soil respiration, net CO2 flux, and net CH4 flux

Atmospheric exchange of carbon dioxide in a low‐wind oligotrophic lake measured by the addition of SF6

Many freshwater lakes are supersaturated in CO2 with respect to the atmosphere. This concentration gradient implies a net flux of CO2 from the water to the air. The actual rate of gas exchange is

Environmental controls on ecosystem‐scale CH4 emission from polygonal tundra in the Lena River Delta, Siberia

[1] We present the first ecosystem-scale methane flux data from a northern Siberian tundra ecosystem covering the entire snow-free period from spring thaw until initial freeze-back. Eddy covariance

Role of lakes for organic carbon cycling in the boreal zone

We calculated the carbon loss (mineralization plus sedimentation) and net CO2 escape to the atmosphere for 79 536 lakes and total running water in 21 major Scandinavian catchments (size range 437–48

Hydrologic influence on methane and carbon dioxide dynamics at two north‐central Minnesota lakes

Annual emissions of (CH4 + CO2) to the atmosphere were proportional to net hydrologic inputs of C, mostly by groundwater, at two lakes in the Shingobec River watershed in north‐central Minnesota.

A snapshot of CO2 and CH4 evolution in a thermokarst pond near Igarka, northern Siberia

[1] Thermokarst wetlands and ponds in the subarctic, which are located in land surface depressions resulting from permafrost melt, are strong sources of CH4, but little is known about respiration

Methane production and bubble emissions from arctic lakes: Isotopic implications for source pathways and ages

[1] This study reports an atmospheric methane (CH4) source term previously uncharacterized regarding strength and isotopic composition. Methane emissions from 14 Siberian lakes and 9 Alaskan lakes
