Abstract

This Modeling Archive is in support of an NGEE Arctic publication "The importance of freeze/thaw cycles on lateral transport in ice-wedge polygons".The dataset includes xml input/configuration files. These files are compatible with the ATS version 1.0 and higher. The mesh folder contains mesh files used for high-centered polygon (hcp) and low-centered polygon (lcp). The mesh files represent the transect of the polygonal tundra (Fig 1). Here we used two types of mesh with impermeable layer and without. The mesh with an impermeable layer corresponds to the synthetic permafrost (no freezeup case). The freeze up case uses mesh without impermeable layer to simulated frozen ground start at the same depth where the impermeable layer is for the no freezeup case. The meteorological data used drive the model saved in the ?inputs? folder. The processed tracer flow rates are saved in the ?tracer-flow-rates? folder. To plot figures 1 and 2, we used VisIt software. To plot all the flow rates, we used ipython notebook script. All required inputs are saved in ?freezeup? and ?no freezeup? folders. Each folder includes the corresponding ?lcp? and ?hcp? folders. The ?freezeup? folder has also flat-centered polygon (fcp) case, low porosity ?lpor?, and low permeability ?lper? cases.NGEEmore »« less

NGEE Arctic was supported by the Department of Energy?s Office of Biological and Environmental Research.The NGEE Arctic project had two field research sites: 1) located within the Arctic polygonal tundra coastal region on the Barrow Environmental Observatory (BEO) and the North Slope near Utqiagvik (Barrow), Alaska and 2) multiple areas on the discontinuous permafrost region of the Seward Peninsula north of Nome, Alaska.Through observations, experiments, and synthesis with existing datasets, NGEE Arctic provided an enhanced knowledge base for multi-scale modeling and contributed to improved process representation at global pan-Arctic scales within the Department of Energy?s Earth system Model (the Energy Exascale Earth System Model, or E3SM), and specifically within the E3SM Land Model component (ELM).},

The importance of freeze–thaw cycles for lateral tracer transport in ice-wedge polygons

Journal Article Jafarov, Elchin E. ; Svyatsky, Daniil ; Newman, Brent ; ... - The Cryosphere (Online)

Abstract. A significant portion of the Arctic coastal plain is classified as polygonal tundra and plays a vital role in soil carbon cycling. Recent research suggests that lateral transport of dissolved carbon could exceed vertical carbon releases to the atmosphere. However, the details of lateral subsurface flow in polygonal tundra have not been well studied. We incorporated a subsurface transport process into an existing state-of-the-art hydrothermal model. The model captures the physical effects of freeze–thaw cycles on lateral flow in polygonal tundra. The new modeling capability enables non-reactive tracer movement within subsurface. We utilized this new capability to investigate themore »« less

Feedbacks Between Surface Deformation and Permafrost Degradation in Ice Wedge Polygons: Modeling Archive

Dataset Abolt, Charles ; Young, Michael ; Atchley, Adam ; ...

This Modeling Archive is in support of an NGEE Arctic publication ?Feedbacks between surface deformation and permafrost degradation in ice wedge polygons,? submitted for review to the Journal of Geophysical Research: Earth Surface. The goals of the study were: 1) to determine how variability in microtopographic conditions (i.e., rim height, trough width, and trough depth) and hydrologic conditions in the trough (i.e., inundated or well-drained) of an ice wedge polygon impact active layer thickness above an ice wedge; and 2) to determine how microtopographic and hydrologic controls on active layer thickness may influence thermokarst trajectories in ice wedge polygon terrain.more »« less
Spatially Averaged Ice Contents of Ice-Wedge Polygon Cross-Sections to 3-m Depth, July 2013, Utqiagvik, Alaska

Dataset Jastrow, Julie ; Matamala, Roser ; Ping, Chien-Lu ; ...

This dataset contains spatially averaged estimates of ice content (volume percent) for two-dimensional cross-sectional profiles (from trough center to trough center to a depth of 3 meters) of low- and flat-centered ice-wedge polygons (three of each type) located near Utqiagvik, Alaska. A combination of soil pits, trenches, and cores were used to describe, sample, and map the cross-section stratigraphy of soil horizons and ice wedges for each polygon at 6 depth intervals. Observed soil horizons were assigned to four types with increasing amounts of organic components (mineral, mineral/organic, organic/mineral, and organic). The average ice contents of each soil horizon typemore »« less
The impact of freeze-thaw history on soil carbon response to experimental freeze-thaw cycles

Dataset Rooney, Erin ; Rooney, Erin ; Bailey, Vanessa ; ...

This dataset contains data used for the paper "The impact of freeze-thaw history on soil carbon response to experimental freeze-thaw cycles". The Related References field will be updated with a full citation when available.Freeze-thaw is a disturbance process in cold regions where permafrost soils are becoming vulnerable to temperature fluctuations above 0˚C. Freeze-thaw alters soil physical and biogeochemical properties with implications for carbon persistence and emissions in Arctic landscapes. We examined whether different freeze-thaw histories in two soil systems led to contrasting biogeochemical responses under a laboratory-controlled freeze-thaw incubation. We investigated controls on soil organic matter (SOM) composition through Fourier-transformmore »« less
