This dataset includes monthly measurements of carbon dioxide and methane exchange between land, water, and the atmosphere from over 1000 sites in Arctic and boreal regions. It combines measurements from a variety of ecosystems, including wetlands, forests, tundra, lakes, and rivers, gathered by over 260 researchers from 1984–2024. This dataset can be used to improve and reduce uncertainty in carbon budgets in order to strengthen our understanding of climate feedbacks in a warming world.

We created a database of 19,540 thawing permafrost sites across Alaska, including both abrupt and non-abrupt thaw features and explored relationships with elevation, slope, and incoming solar radiation. We use the database to show that existing ground ice maps are too coarse to predict abrupt thaw risk. This database can enhance predictions of future thaw and guide planning and adaptation strategies.

Thermokarst lakes have formed over thousands of years from permafrost thaw in the Arctic. Here, we quantify the change in methane production rates as thermokarst lakes evolve through an incubation-based approach of measuring and comparing methane production rates and organic carbon lability between a more mature thermokarst lake and a young dynamic thermokarst lake. We also show the use of the Rock-Eval analysis of organic carbon along the sediments as a proxy for organic susceptibility for methanogenesis.

Peatlands are complex and widespread ecosystems that store large amounts of carbon through photosynthesis. Carbon fixation depends on solar irradiance, and the relationship between them is called the photosynthesis-irradiance or “PI” curve. We developed a simple, portable chamber to measure PI curves in peatlands, taking into account complex plant assemblages and microhabitat variability. This tool may help scientists better understand carbon dynamics in these ecosystems.

Short summary
Methane (CH4) emissions from the boreal–Arctic region are globally significant, but the current magnitude of annual emissions is not well defined. Here we present a dataset of surface CH4 fluxes from northern wetlands, lakes, and uplands that was built alongside a compatible land cover dataset, sharing the same classifications. We show CH4 fluxes can be split by broad land cover characteristics. The dataset is useful for comparison against new field data and model parameterization or validation.

Short summary
We assessed the importance of aerobic CH4 oxidation in Alaskan lakes. We conducted field measurement of dissolved CH4 and O2 together with determination of the CH4 oxidation rate. We found that during winter, CH4 oxidation was limited by O2 concentration and during summer, by CH4 concentration. In addition to seasonal variations, the type of permafrost on which the lakes were located was identified as a key factor, indicating that landscape processes play an important role in lake CH4 cycling.
