This dataset includes locations and water surface elevation measurements from submersible pressure transducers deployed in channels of three rivers in Alaska: Susitna and Yukon Rivers (July-October 2020), and Nushagak River (May to September 2021).
Water Surfaces Elevations from Pressure Transducers on the Tanana River near Fairbanks, Alaska, 2016
This dataset includes locations, and water surface elevations from two submersible pressure transducers deployed in the channel of the Tanana River downstream of Fairbanks Alaska in 2016.
Water Surfaces Elevations During an Outburst Flood from Pressure Transducers at Snow River, Alaska, 2019
This dataset includes locations, pressure readings, and baro-corrected water surface elevations from three submersible pressure transducers deployed in the channel and floodplain of Snow River during the 2019 glacial lake outburst flood.
Water Level, Temperature, and Discharge in West Twin Creek, Alaska, 2010 to 2012
This data set includes 15-minute interval data on stream temperature, stage, and discharge from an upstream and downstream gaging location on West Twin Creek, a first-order tributary to Nome Creek in the White Mountains of Alaska.
Water Level, Temperature, and Discharge of Headwater Streams in the Yukon River Basin, Alaska, 2016 and 2017
This data set includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Yukon River Basin in interior Alaska, collected during the summer months. 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 an
Water Level, Temperature, and Discharge of Headwater Streams in the Noatak and Kobuk River Basins, Northwest Alaska, 2015 - 2017
This data set 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 combine

Macroinvertebrates from Rivers in Northwest Alaska, 2015-2019
This dataset contains taxonomic information, counts, and lengths of macroinvertebrates collected from rivers in northwest Alaska using drift and kick nets during summer and fall 2015-2019.
Estimates of Iron Mineralization in Select Reaches of Three Alaska Arctic Rivers Derived from Historical Landsat Imagery
These data are in three tables each reporting estimated iron mineralization within stream reaches from three arctic rivers in northwestern Alaska on select days between July-August, 1985-2022. The relative magnitude of iron mineralization was measured using a remotely sensed iron index calculated from available Level 2, Collection 2, Tier 1 Landsat Surface Reflectance products derived by the USGS
Hydrochemistry and Age Date Tracers from Springs, Streams, and Rivers in the Arctic National Wildlife Refuge, 2019-2022
These data include water chemistry from springs, streams, rivers, and shallow groundwater collected in the Arctic National Wildlife Refuge in northern Alaska. Chemical analyses were performed for hydrochemical parameters including field parameters, major ions, nutrients, metals, stable isotopes of water, and tritium, as well as for dissolved gases useful for determining the timescale over which th
Chemistry of Orange and Reference Streams in Northwestern Alaska
These data include water chemistry from headwater streams to large rivers that have recently turned orange and reference rivers that have not. These samples were collected in two national parks in Arctic Alaska: Kobuk Valley National Park, and Noatak National Preserve.
Stream and River Chemistry in Watersheds of Northwestern Alaska, 2015-2019
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.
Geochemistry of Water Sources in the Wolverine Glacier Watershed, Alaska in 2016 and 2017
Glaciers are critical sources of water and solutes to downstream riverine and marine ecosystems. Samples were collected from surface streams, groundwater, rain, snow, and ice in the Wolverine Glacier basin and analyzed for a broad suite of geochemical constituents including common field parameters, major ions, stable isotopes of water, nutrients, metals, and dissolved organic carbon.
Continuous Records of Shallow Soil Temperature and Moisture in the Noatak River Basin, Alaska
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.
Physical, Hydraulic, and Thermal Properties of Soils in the Noatak River Basin, Alaska, 2016
This dataset includes physical, hydraulic, and thermal properties of soils collected in two sub-watersheds in the Noatak River Basin in northwestern Alaska. Physical properties include dry bulk density and porosity. Hydraulic properties include field- and lab-based hydraulic conductivity, soil-water retention data, and parameters used in a common soil-water retention model (van Genuchten model). T
Physical, Chemical, and Invertebrate Data from Chipp North Pond Manipulations, North Slope, Alaska, 2013
These data are in three tables relating to a series of ponds, visited weekly over the summer of 2013, in the Chipp River Basin on the Arctic Coastal Plain of northern Alaska. The tables provide: 1) location and description of each of the ponds, 2) physical information on pond characteristics (area, volume, and temperature), water chemistry (electrical conductivity, dissolved oxygen, pH, ammonium,
Arctic Coastal Plain Seasonal Lake Drainage, Water Temperature, and Solute and Nutrient Concentrations, 2011 - 2014
This data release includes remotely sensed lake and lake chemistry and water temperature data collected from 2011 to 2014) from a series of lakes on the Arctic Coastal Plain of Alaska. Most of the data is from two sites within the Chipp River Basin.
