Kuparuk River

Stream networks are intimately connected to the landscapes through which they flow and significantly transform nutrients and organic matter that are in transport from landscapes to oceans. This work will quantify the relative influences of throughflow, lateral inputs, and hyporheic (a layer of surface sediments that contains water which exchanges continuously with water in the open channel) regeneration on the seasonal fluxes of C, N, and P in an arctic river network, and determine how these influences will shift under seasonal conditions that are likely to be substantially different in the future. This objective is a logical extension of earlier. This work will focus on seasonal dynamics at different river reach scales (1st to 4th order streams) and will lay the groundwork for a whole river network model to integrate the influences of throughflow, lateral inputs, hyporheic regeneration, and in-stream metabolism on C, N, and P fluxes through an entire river network.

Changing Seasonality and Arctic Stream Networks
Title Abstract
CSASN Channel Nutrients from 2010 to 2012 in I8 Inlet, I8 Outlet, Peat Inlet and Kuparuk Rivers
The Changing Seasonality of Arctic Stream Systems (CSASN) was active from 2010 to 2012. The CSASN goal was to quantify the relative influences of through flow, lateral inputs, and hyporheic regeneration on the seasonal fluxes C, N, and P in an arctic river network, and to determine how these influences might shift under seasonal conditions that are likely to be substantially different in the future. During the project, background samples were collected from four stream channels and analyzed... more

Streams Insects
Title Abstract
Total numbers per square meter and taxa of insects taken from the Kuparuk River during the summer of 2001, Arctic LTER 2001.
A Surber sampler (25 X 25 cm frame fitted with a 243 um mesh net) was used to sample invertebrates at several different stations. Two replicates were taken from each station. The same sampling procedure was used for all dates. The stations were measured relative to the site of the dripper ("-" = upstream of the dripper). Samples were preserved in 4% formaldehyde and transported to Orono, Maine, where invertebrates were removed by hand under 15X magnification and then... more
Total numbers and species of insects taken from rock scrubbings during the summer of 1984-1988, 1993-1994, 1996-1998, in the Kuparuk River experimental reach near Toolik Field Station, North Slope Alaska..
A rock-scrubbing technique was used to collect bottom samples at several different stations with three replicates at each station in the Kuparuk River. The stations are measured relative to the 1984 phosphorus dripper. Only July sampling dates are included in this file (ACG). The samples were preserved in ethanol then picked, sorted, counted, and measured in Duluth using a NIKON MICRO-PLAN II digitizing pad.
Streams Chemistry
Title Abstract
Arctic LTER Streams Chemistry Toolik Field Station, Alaska 1983 to Present.
Since 1983, the Streams Project at the Toolik Field Station has monitored physical, chemical, and biological parameters in a 5-km, fourth-order reach of the Kuparuk River near its intersection with the Dalton Highway and the Trans-Alaska Pipeline. In 1989, similar studies were begun on a 3.5-km, third-order reach of a second stream, Oksrukuyik Creek.

In each river, physical conditions (such as discharge and temperature), nutrient levels, primary production, insects, and fishes are... more

Arctic Grayling Growth in the Kuparuk River; data from 1986-2003
Adult Arctic Grayling were caught and tagged in the Kuparuk River. A second fishing campaign occurred later in the summer, and any fish that was recaptured was remeasured to determine growth. Phosphorus addition has occurred since 1983; station sites are relative distance from the original 1983 phosphorus dripper. Stations include sites in a reference, recovery, and fertilized reach. Reaches were defined based on the location of phosphorous addition (see methods). Arctic Grayling were... more
