Egg thiamine content, length, weight and survival of steelhead (Oncorhynchus mykiss) exposed to three methods of experimental thiamine supplementation in 2022 and egg thiamine content from three Oregon hatcheries in 2019 Egg thiamine content, length, weight and survival of steelhead (Oncorhynchus mykiss) exposed to three methods of experimental thiamine supplementation in 2022 and egg thiamine content from three Oregon hatcheries in 2019
Early rearing of steelhead (Oncorhynchus mykiss) in Oregon hatcheries is often problematic; fry can become emaciated and die during the period between hatch and first feed. Thiamine (vitamin B1) deficiency has caused early mortality in salmonids; however, thiamine status of Oregon’s anadromous steelhead populations is currently unknown. We sampled eggs of 7-10 females during spawning...
Model Archive Summary and Time-Series Suspended-Sediment Concentration Computed from a Surrogate Turbidity Regression at USGS Station 11336790; Little Potato Slough at Terminous, California (2011-2015) Model Archive Summary and Time-Series Suspended-Sediment Concentration Computed from a Surrogate Turbidity Regression at USGS Station 11336790; Little Potato Slough at Terminous, California (2011-2015)
Model archive summary (MAS) describing the development of a continuous 15-minute suspended-sediment concentration (SSC) time series regression model for the site: Little Potato Slough at Terminous (U.S. Geological Survey (USGS) site # 11336790). The SSC time series is computed from instream turbidity data that is managed by the USGS using a YSI 6-series multi-parameter water quality...
Data release for "Effect of thermal and mechanical processes on hydraulic transmissivity evolution" Data release for "Effect of thermal and mechanical processes on hydraulic transmissivity evolution"
Laboratory flow-through tests were conducted during slide-hold-slide experiments in a conventional triaxial deformation configuration. Experiments were conducted on 1-inch diameter cylindrical cores of Westerly granite bisected by a sawcut oriented at 30 degrees from vertical. Tests were conducted at a constant confining pressure of 30 MPa with a 10 MPa pore fluid pressure. The pore...
Invertebrate data (2012-2021) from the Colorado River in Grand Canyon and flow data (1921-2021) from the Lees Ferry gage (09380000) on the Colorado River near Page, AZ Invertebrate data (2012-2021) from the Colorado River in Grand Canyon and flow data (1921-2021) from the Lees Ferry gage (09380000) on the Colorado River near Page, AZ
These data were compiled for an outreach article published in the Boatman's Quarterly Review, which is a magazine published by Grand Canyon River Guides Association. The objectives of our study was to describe the outcomes of the 2018-2020 Bug Flows experiment to a general audience. These data represent 10 years (2012-2021) of invertebrate data and 100 years (1921-2021) of flow data...
Algal toxins and Mycobacterium avium ssp. paratuberculosis measured in surface-water, quarry-water, and sediment samples collected at Pipestone National Monument, Pipestone, Minnesota, 2018-19 Algal toxins and Mycobacterium avium ssp. paratuberculosis measured in surface-water, quarry-water, and sediment samples collected at Pipestone National Monument, Pipestone, Minnesota, 2018-19
The U.S. Geological Survey, in cooperation with the U.S. National Park Service, conducted a study to determine the presence of algal toxins and Mycobacterium avium ssp. paratuberculosis (MAP) within Pipestone National Monument located in Pipestone County in southwestern Minnesota. Three algal toxins (microcystins, saxitoxin, and anatoxin-a) were analyzed in 12 water-quality samples...
Limnological Data from Experimental Exposure of Juvenile Coho Salmon (Oncorhynchus kisutch) to Elodea in a High Latitude Lake Limnological Data from Experimental Exposure of Juvenile Coho Salmon (Oncorhynchus kisutch) to Elodea in a High Latitude Lake
This dataset provides nine tables of data from an experimental study in which juvenile Coho Salmon (Oncorhynchus kisutch) were reared in floating net pens (limnocorrals) and exposed to Elodea spp. (a potential invasive species in high latititude lakes) and native aquatic vegetation. Data include: (1) coho salmon body, otolith, and stable isotope measurements, (2) abundance of...
U-Pb Ages, Hafnium Isotope Ratios, and Trace Element Concentrations by Laser-Ablation Split Stream (LASS) Analysis of Igneous Zircons from the Western Alaska Range U-Pb Ages, Hafnium Isotope Ratios, and Trace Element Concentrations by Laser-Ablation Split Stream (LASS) Analysis of Igneous Zircons from the Western Alaska Range
This dataset contains U-Pb isotopic data and ages, Hf isotope data, and trace element concentrations of zircon from igneous rocks collected from the western Alaska Range of south-central Alaska. The sample suite was collected as part of geological mapping and supporting geochemical and geochronological analysis conducted from 2011 to 2013. We also analyzed portions of remainders of...
