Electron microprobe and 40Ar/39Ar isotopic data from west-central New Hampshire Electron microprobe and 40Ar/39Ar isotopic data from west-central New Hampshire
This dataset accompanies planned publication 'Unmixing multiple metamorphic muscovite age populations with powder X-ray diffraction and 40Ar/39Ar analysis'. The 40Ar/39Ar and electron microprobe data are from samples adjacent to a lower greenschist facies shear zone in western New Hampshire. The geochronology coupled with the electron microprobe data provide a petrochronologic framework...
Two-dimensional HEC-RAS models and topo-bathymetric datasets for the Willamette River, Oregon Two-dimensional HEC-RAS models and topo-bathymetric datasets for the Willamette River, Oregon
This dataset contains two-dimensional hydraulic models throughout the Willamette River, extending from the McKenzie River confluence, near Eugene, to the city of Newberg. The study reach is separated into five individual models to simplify tributary inflow boundary conditions and for run-time efficiency. These models were developed to assess juvenile salmonid habitat at streamflows...
Single-beam Echosounder Bathymetry of the Willamette River, Oregon 2015-2018 Single-beam Echosounder Bathymetry of the Willamette River, Oregon 2015-2018
River bathymetry measurements were collected in 2017 and 2018 along the Willamette River, Oregon, between Eugene and Newberg. These data were collected to complement a bathymetric lidar dataset collected in 2017 for the same section of river. In many deeper segments of the river channel, bathymetric lidar did not produce measurements of river bathymetry. To fill gaps in the bathymetric...
Seawater chemistry and physical property profiling using CDT casts above two seafloor pockmarks on the Miami Terrace offshore of southeastern Florida, 2016 Seawater chemistry and physical property profiling using CDT casts above two seafloor pockmarks on the Miami Terrace offshore of southeastern Florida, 2016
In the Atlantic Ocean and above the Miami Terrace off southeastern Florida, a total of nine CTD (conductivity, temperature, and depth) casts were performed using the 115-foot Research Vessel (R/V) Weatherbird II above the submerged Miami Terrace at the Miami pockmark and Key Biscayne pockmark from May 4 to May 8, 2016. A CTD is a package of electronic instruments and sampling devices...

Photosynthetically Active Radiation Measurements Collected at Malheur Lake, OR, 2017-2018 Photosynthetically Active Radiation Measurements Collected at Malheur Lake, OR, 2017-2018
The USGS measured photosynthetically active radiation (PAR, wavelength between 400 and 700 nanometers) at Malheur Lake, Oregon, as vertical profiles and as continuous measurements at a fixed depth, in 2017 and 2018. Malheur Lake is a large, shallow, turbid lake located in southeastern Oregon that fluctuates widely in surface area in response to yearly precipitation and climatic cycles...
