Description:

Abstract:

This dataset includes soil data collected from various landscapes adjacent to thaw ponds on the North Slope of Alaska between 2012 and 2018. The landscapes include ice-rich polygonal ground found on basin uplands, as well as bluffs and lake edges. At each site a visual description of soil type and texture was performed, and a permafrost probe was used to determine a 'depth to refusal'. Given that the soils are mostly fine-grained and there were no obvious rock strikes, we believe that 'depth to refusal' indicates the thaw depth. Field-saturated hydraulic conductivity was determined in most locations using a Guelph Permeameter.

Purpose:

These data were collected as part of a larger field effort aimed at understanding the relationship between physical and chemical conditions and fish in thaw lakes on the North Slope of Alaska

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Accuracy was not directly assessed. Depth to refusal can vary spatially, but was accurate to within a few centimeters for each measurement. Hydraulic conductivity may vary depending on which region of the head/time curve is selected, as well as by assumptions of soil structure. Uncertainty may reasonably be on the scale of two-fold, which is small relative to the range of hydraulic conductivity found across soil types (orders of magnitude).

Logical_Consistency_Report:

All data fall within the expected ranges, all measurements that were made are reported. Null values exist in some instances when a measurement was not made, further details are provided in the entity attribute section.

Completeness_Report: Data are complete, no data were omitted.
Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Latitudes and longitudes were determined at CALON sites with a recreation-grade GPS and are accurate on the scale of meters. Locations at the Chipp River were not recorded, the reported lat/long indicates the center of a 250m (north-south) by 500m (east-west) region in which the samples were collected.

Lineage:

Process_Step:

Process_Description:

Guelph Permeameter measurements were made by boring a hole with a hollow auger, and brushing if necessary to remove smearing of grains along the hole walls. A measurement was made at a single head, and water level and time were recorded. A calculation sheet available at producer's website, soilmoisture.com was used to calculate hydraulic conductivity.
