Towards online ramped oxidation (ORO)-AMS for thermal dissection and serial radiocarbon analysis of complex organic matter Open
By constraining organic carbon (OC) turnover times and ages, radiocarbon ( 14 C) analysis has become a crucial tool to study the global carbon cycle. However, commonly used “bulk” measurements yield average turnover times, masking age vari…

Arctic biodiversity responses to climate change impacts in the Canadian Beaufort Sea  Open
The Arctic is experiencing unprecedented rates of warming. Arctic coastal environments are particularly vulnerable to the consequences: thawing of permafrost, decline of sea ice, and increased fluxes of sediment, organic carbon and nutrien…

Bridging the Gap: Nearshore zones as key mediators in Arctic land-ocean carbon fluxes Open
The Arctic is experiencing rapid warming, leading to prolonged ice-free periods, increased storm activity, and intensified coastal erosion. These changes release organic matter-rich permafrost into the nearshore marine environment, where i…

Greenhouse Gas Emissions and Lateral Carbon Dynamics at an Eroding Yedoma Permafrost Site in Siberia (Duvanny Yar) Open
Rapid Arctic warming is accelerating permafrost thaw and mobilizing previously frozen organic carbon (OC) into waterways. Upon thaw, permafrost‐derived OC can become susceptible to microbial degradation that may lead to greenhouse gas emis…

Mineralogy as a potential driver of irregular radiocarbon patterns among Icelandic fluvial carbon pools Open
Fluvial export of organic carbon (OC) from the terrestrial biosphere to the ocean forms a key component of the global carbon cycle. Carbon sources and transformations along the land–ocean aquatic continuum are dynamic with a complex interp…

Rainfall Impacts Dissolved Organic Matter and Cation Export From Permafrost Catchments and a Glacial River During Late Summer in Northeast Greenland Open
Ongoing and amplified climate change in the Arctic is leading to glacier retreat and to the exposure of an ever‐larger portion of non‐glaciated permafrost‐dominated landscapes. Warming will also cause more precipitation to fall as rain, fu…

Traveling Light: Arctic Coastal Erosion Releases Mostly Matrix Free, Unprotected Organic Carbon Open
The Arctic rapidly warms and sea ice retreats, a large fraction of organic carbon (OC), currently stored in coastal permafrost will be released into the marine system. Once reintroduced into the active carbon cycle, this material will eith…

Rapid Ice‐Wedge Collapse and Permafrost Carbon Loss Triggered by Increased Snow Depth and Surface Runoff Open
Thicker snow cover in permafrost areas causes deeper active layers and thaw subsidence, which alter local hydrology and may amplify the loss of soil carbon. However, the potential for changes in snow cover and surface runoff to mobilize pe…

Millennial-aged pyrogenic carbon in high-latitude mineral soils Open
Wildfires in the Arctic are producing pyrogenic carbon as product of incomplete biomass combustion. The storage and distribution of pyrogenic carbon in soils is poorly known, especially in carbon rich permafrost-affected mineral soils. Her…

Fluvial versus coastal input of permafrost organic carbon - insights from the Canadian Beaufort Sea Open
Around 65% of the Arctic coastline consists of permafrost. Rising global air temperatures cause these permafrost grounds to thaw which leads to the release of organic matter and sediments into the coastal ocean. This influences coastal eco…
