Bathymetric data for St. Croix River at outlet to East Grand Lake and Forest City Dam Survey, United States-Canadian border between Maine and New Brunswick Bathymetric data for St. Croix River at outlet to East Grand Lake and Forest City Dam Survey, United States-Canadian border between Maine and New Brunswick
These are survey data for the Forest City Dam at the Outlet to East Grand Lake on the St. Croix River between Maine and Canada. And they are bathymetric data surrounding the outlet dam collected with an Acoustic Doppler Current Profiler (ADCP)
Hakalau Forest NWR Litterfall, Decomposition, Soils, and Seedling Survival Data 2019 Hakalau Forest NWR Litterfall, Decomposition, Soils, and Seedling Survival Data 2019
This data release includes data and metadata on litterfall rates, foliar nitrogen and carbon, grass biomass, soil nitrogen and carbon, and native outplant survival rates for an experiment that added large quantities of woody litter to a restoration forest in an attempt to lower soil nitrogen and exotic grass biomass. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii...
Carbon, nitrogen, and phosphorus content of adult emergent Diptera before and after a fire-storm sequence in the Colorado River near Shinumo Creek, Grand Canyon, AZ Carbon, nitrogen, and phosphorus content of adult emergent Diptera before and after a fire-storm sequence in the Colorado River near Shinumo Creek, Grand Canyon, AZ
This dataset includes total phosphorus (TP), total nitrogen (TN), and total carbon (TC) concentrations as well as δ15N and δ13C composition, and overall C:N:P stoichiometry for adult emergent Diptera from the Colorado River, Grand Canyon, AZ. The samples were collected before and after a fire and subsequent storm occurred in the Shinumo Watershed, a tributary to the Colorado River in...
Hydrologic reconnaissance to identify areas of emergent groundwater, Mineral Creek, near Silverton, Colorado, June 2020 Hydrologic reconnaissance to identify areas of emergent groundwater, Mineral Creek, near Silverton, Colorado, June 2020
Hydrologic reconnaissance of Mineral Creek near Silverton, Colo., was conducted from June 25-27, 2020. Both banks of Mineral Creek and the adjacent hillsides were walked, starting near the ghost town of Chattanooga and proceeding downstream to the confluence of Mineral Creek with the Middle Fork of Mineral Creek. The purpose of this reconnaissance was to identify areas of emergent...
Stable Isotope Data from Tundra Swan (Cygnus columbianus) Feathers, Alaska, 2008 and 2010 Stable Isotope Data from Tundra Swan (Cygnus columbianus) Feathers, Alaska, 2008 and 2010
These data are in a single table that provides date and location information of Tundra Swans (Cygnus columbianus) that were sampled in Alaska for feathers that were subsequently used in a stable isotope analysis. Results of deuterium, nitrogen, and carbon stable isotope analysis of feathers are provided.
Calculated mercury and carbon concentrations, USGS station 254543080405401: Tamiami Canal at S-12D Near Miami, FL, 2013-2017 Calculated mercury and carbon concentrations, USGS station 254543080405401: Tamiami Canal at S-12D Near Miami, FL, 2013-2017
This data release provides data for filter-passing total mercury, filter-passing methylmercury, particulate total mercury, particulate methylmercury, and dissolved organic carbon concentrations calculated for USGS station 254543080405401: Tamiami Canal at S-12D Near Miami, FL. Five site-specific regression models were developed using continuously measured temperature, turbidity, specific
