Soil moisture and temperature were measured at four shallow depths in multiple locations within tundra and forested landscapes of the Agashashok River basin. The measurements were made continuously beginning in 2015 until the most recent download in summer, 2019 or until the sensors or loggers failed.

This dataset includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Noatak and Kobuk River valleys in Northwestern Alaska, collected during the summer months. Several sites in the Agashashok River basin were monitored in 2015 and 2016, and additional sites were added in 2017. The depth of the water and temperature were determined using a combined pressure transducer and temperature sensor that was deployed through the summer months. Different sensors were used in each stream and year, so a file is included detailing the stage and temperature accuracy for each year and stream. In rare instances in the fall, stage was estimated for certain streams (e.g. NFT3) based on remote camera images of the staff plate. Discharge was derived from the stage data by creating a rating curve relating stage to discharge measured during site visits.

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.

These data include stream water chemistry from headwater streams to large rivers across three national parks in Arctic Alaska: Bering Land Bridge National Preserve, Kobuk Valley National Park, and Noatak National Preserve.

This dataset includes physical and hydraulic properties at selected sites in interior Alaska. These properties include soil-water retention data, and parameters used in a common soil-water retention model (van Genuchten model).

This dataset includes volumetric soil-water content profiles with depth at selected sites in interior Alaska.

This dataset includes physical and hydraulic properties at selected sites in interior Alaska. Physical properties include dry bulk density, loss on ignition, saturated soil water content, and particle size distribution. Hydraulic properties include field-saturated hydraulic conductivity, soil-water retention data, and parameters used in a common soil-water retention model (van Genuchten model). Volumetric soil-water content profiles with depth are also included. Note that unburned locations are dentoed with UB and burned locations are denoted with B.
