• The thermal response of permafrost to coastal floodplain flooding

  Open Access•Yu Zhang, Elchin Jafarov et al.•ARTICLE•Environmental Research Letters•2023

  Añadir item

  Flooding of low-lying Arctic regions has the potential to warm and thaw permafrost by changing the surface reflectance of solar insolation, increasing subsurface soil moisture, and increasing soil thermal conductivity. However, the impact of flooding on permafrost in the continuous permafrost environment remains poorly understood. To address this knowledge gap, we used a combination of available flooding data on the Ikpikpuk delta and a numerical…

• Variability in terrestrial characteristics and erosion rates on the Alaskan Beaufort Sea coast

  Open Access•Anastasia Piliouras, Benjamin M Jones et al.•ARTICLE•Environmental Research Letters•2023

  Añadir item

  Arctic coastal environments are eroding and rapidly changing. A lack of pan-Arctic observations limits our ability to understand controls on coastal erosion rates across the entire Arctic region. Here, we capitalize on an abundance of geospatial and remotely sensed data, in addition to model output, from the North Slope of Alaska to identify relationships between historical erosion rates and landscape characteristics to guide future modeling and …
