09471580 - San Pedro River at St David, AZ - 2019/12/05 GPS Survey 09471580 - San Pedro River at St David, AZ - 2019/12/05 GPS Survey

The dataset contains data from a GPS survey conducted after a flow event on November 29, 2019, at the USGS streamgage 09471580 - San Pedro River at St David, AZ. The survey, conducted on December 5, 2019, documents cross section geometry and high-water marks from the flow event in the reach downstream from the gage. One CSA pin elevation at CSA 09471588 - San Pedro River below Dragoon...

Reported groundwater levels and groundwater pump-and-treat withdrawal volumes, former Naval Air Warfare Center, West Trenton, New Jersey, 2018 Reported groundwater levels and groundwater pump-and-treat withdrawal volumes, former Naval Air Warfare Center, West Trenton, New Jersey, 2018

This dataset contains U.S. Navy contractor-reported groundwater level data measured on June 18, 2018 and reported daily total groundwater pump-and-treat withdrawal volumes for calendar year 2018 at the former Naval Air Warfare Center, West Trenton, New Jersey. This data release supports: Fiore, A.R., and Lacombe, P.J., 2020, Groundwater levels and generalized potentiometric surfaces...

Physical characteristics of pallid sturgeon and shovelnose sturgeon eggs Physical characteristics of pallid sturgeon and shovelnose sturgeon eggs

This dataset describes the diameter, shape, settling velocity, and specific gravity of eggs from 9 female pallid sturgeon and 14 female shovelnose sturgeon as determined in laboratory studies. Pallid sturgeon and shovelnose sturgeon are believed to broadcast demersal eggs in the current, near the river bed over coarse substrate. It is hypothesized that eggs settle immediately following

Orthoimagery and elevation data derived from UAS imagery for the Midnight Meadows management area, Carson National Forest, 2018 Orthoimagery and elevation data derived from UAS imagery for the Midnight Meadows management area, Carson National Forest, 2018

Point cloud data set (.las), Digital Elevation Model (DEM, .tif) and orthoimagery (.tif) for the USFS Midnight Meadows fen area during initial stages of cattle exclosure and stream restoration. Aerial images of fens at the Midnight Meadows management area of Carson National Forest, New Mexico were collected on 12 September, 2018 using Unoccupied Aerial Systems (UAS, or "drones"). Data...

Greenhouse gas fluxes, dissolved gas concentrations, and water properties of laboratory mesocosms Greenhouse gas fluxes, dissolved gas concentrations, and water properties of laboratory mesocosms

These data describe greenhouse gas (GHG) emissions, dissolved GHG concentrations, and mesocosm conditions (vegetation, hydrologic phases, ambient conditions) of a controlled, laboratory study.

Microsatellite data for American bullfrogs in the Yellowstone River Montana, 2013-2017 Microsatellite data for American bullfrogs in the Yellowstone River Montana, 2013-2017

We used 7 microsatellites to characterize the invasion genetics of 528 American bullfrogs sampled from the Yellowstone River floodplain (Montana). American bullfrog samples were collected from a 140 km section of the Yellowstone River near Billings, MT in 2013 - 2017.
