Specific conductance: Firehole River near West Yellowstone, USGS Gage 06036905

Measuring the thermal output of Yellowstone’s large magmatic system is not straightforward, as there are thousands of thermal features spread across 3470 square miles. One way to capture and integrate the contributions from this broad area is to monitor river chemistry, because thermal water discharge eventually enters a nearby river, which acts as a collection and delivery system. Nearly all the chloride in rivers that drain Yellowstone comes from emerging hot spring water heated underground by underlying magma. Monitoring river chemistry is therefore an important way to track the behavior and overall changes in Yellowstone’s hydrothermal system. By monitoring the chloride flux, the hydrothermal discharge and heat flux from Yellowstone can be estimated and variations (both short- and long-term) can be used to identify changes in the deep hydrothermal system, earthquake activity, geyser eruptions, and other natural events (like floods and the impacts of wildfire). The U.S. Geological Survey (USGS) and the National Park Service (NPS) have collaborated on Cl flux monitoring of the major rivers since the 1970s. In the past, researchers collected water samples from the major rivers in YNP, but funding restrictions, winter conditions, and the great distances between sites limited the number of samples collected annually. Beginning in 2010, specific conductance, which is relatively easy to measure and can be automated, has been used as a proxy for Cl. The use of specific conductance probes at the various monitoring sites enables a more consistent estimation of Cl flux.

Vegetation measurements of production and offtake in cottonwood communities of the Great Sand Dunes ecosystem, Colorado, 2005-2009.

These data provide measurements of cottonwood production and herbaceous production in cottonwood communities of the Great Sand Dunes National Park ecosystem in the San Luis Valley of Colorado, from 2005-2009. These data also include cottonwood browsing rates. The study area was stratified into 2 ungulate strata:  areas with elk and bison herbivory, and areas with just elk herbivory (bison not present). Ungulate exclosures were erected in 2005, with n= 4 exclosures and paired grazed sites in elk-only areas, and n=4 exclosures and paired grazed sites in elk + bison areas. We measured sapling density inside and outside exclosures, height of cottonwoods inside and outside of exclosures, herbaceous production, baseline browsing rate of cottonwoods in summer 2005 (pre-treatment) and subsequent years of mean percent cottonwood twig utilization. We also present Index depth to water (cm), measured at nearest well to site at time of maximal water table height (late June) for spring/summer 2007.

Acoustic-backscatter data from Floras Lake, Oregon, June 2018

This portion of the USGS data release presents acoustic-backscatter data collected during surveys performed in Floras Lake, Oregon in June 2018 (USGS Field Activity Number 2018-636-FA). Lake bed backscatter data were collected using a personal watercraft (PWC) equipped with a sidescan sonar system and global navigation satellite system (GNSS) receivers. The sonar system consisted of a Tritech Starfish 990F with a 1-MHz transducer and a 0.3-degree horizontal beam width. Output from the GNSS receivers and sonar system were combined in real time on the PWC by a computer running HYPACK hydrographic survey software. Navigation information was displayed on a video monitor, allowing PWC operators to navigate along survey lines at speeds of 2 to 3 m/s. Survey-grade positions of the PWCs were achieved with a single-base station and differential post-processing. Positioning data from the GNSS receivers were post-processed using Waypoint Grafnav to apply differential corrections from a GNSS base station with known horizontal and vertical coordinates relative to the North American Datum of 1983.

Partitioning of six pyrethroid insecticides at varying salinities

To determine aqueous pyrethroid partitioning across a salinity gradient 20 mL Pyrex beakers were filled with 8 mL of deionized water at varying salinities (0, 0.5, 2, 6 ppt). Salinity was adjusted using a 10 ppt stock solution (made by diluting Instant Ocean into deionized water). The water samples were spiked with pyrethroids (bifenthrin, cyhalothrin, cyfluthrin, cypermethrin, deltamethrin, esfenvalerate, fenpropathrin) at 500 ng/L (pyrethroid stock solution was 0.25 ng/µL in acetone, 16 µL added to each beaker). Samples were equilibrated in the dark (beaker covered with aluminum foil and placed in a cardboard box; the first set was equilibrated for 24 hr, the second set for 120 hr). Each set of samples at a particular salinity and time were run in triplicate. An additional set of samples were run for 24 hr with the addition of 30 mg/L of suspended sediment. At the end of the specified time, the water was gently removed from the beaker with a pipette and run through a solid phase extraction (SPE) cartridge (Water Oasis HLB, 3 cc 60 mg) and eluted with ethyl acetate (3 mL) to determine the fraction of pyrethroids in the water. After the removal of the water, the beaker was then rinsed twice with 0.5 mL of dichloromethane (rinses were combined) and exchanged into ethyl acetate to give fraction associated with the beaker surface. Both the SPE eluent and beaker rinses were reduced to 50 µL in ethyl acetate and analyzed via gas chromatography-mass spectrometry (GC-MS). The fraction of pyrethroids in the aqueous phase increased with increasing salinity.

Fluvial transport of bedload, suspended sediment, and silicate solutes in watersheds of western Oregon and northwestern California (1901-2016)

These data sets contain the estimated fluvial transport of bedload, suspended sediment, and silicate solutes in the watersheds of western Oregon and northwestern California. The estimates for bedload represent mean conditions that existed during the 20th century, the estimates for suspended sediment represent mean conditions that existed between 1983 and 2012, and the estimates for silicate solutes represents mean conditions that existed between 1951 and 2016. The file “All_HUC12_fluvial_transport.txt” contains landscape attributes and estimates of fluvial transport for each component of the total fluvial load for all watersheds. The file “Select_HUC12_total_yields.txt” contains much of the same information as found in file “All_HUC12_fluvial_transport.txt” for a subset of those watersheds, in addition to the total fluvial yields, the fraction of the total yields contributed by each component, and estimates of landscape denudation rates based on those total yields.
