Issues Related to Incorporating Northern Peatlands into Global Climate Models [PDF]

open access: yes, 2009
Northern peatlands cover ~3–4 million km2 (~10% of the land north of 45°N) and contain ~200–400 Pg carbon (~10–20% of total global soil carbon), almost entirely as peat (organic soil).

Identifying thermokarst lakes using deep learning and high-resolution satellite images

open access: yesScience of Remote Sensing
Thermokarst lakes play a critical role in hydrologic connectivity, permafrost stability, and carbon exchange from local to regional scales. Due to the typically small sizes and highly dynamic nature of thermokarst lakes, their identification in large ...

Present-day permafrost carbon feedback from thermokarst lakes

open access: yes, 2016
Rapid temperature rise during recent decades (IPCC 2013) is causing permafrost in the Arctic to warm and thaw. This thaw exposes previously frozen soil organic carbon (SOC) to microbial decomposition, generating greenhouse gases methane (CH4) and carbon dioxide (CO2) in a feedback process that leads to further warming and thaw.

Arctic and subarctic environmental analyses utilizing ERTS-1 imagery [PDF]

open access: yes
The author has identified the following significant results. ERTS-1 imagery provides a means of distinguishing and monitoring estuarine surface water circulation patterns and changes in the relative sediment load of discharging rivers on a regional basis.
