Cumulative spring discharge and survey effort influence threatened Suwannee moccasinshell, Medionidus walkeri, occupancy and detection

Nathan Johnson, Colin Shea & Jordan Holcomb
Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world. Unionids are plagued with a lack of basic information regarding species distributions, life history characteristics, and ecological and biological requirements. We assessed the influence of hydrologic factors on the occurrence of the Suwannee Moccasinshell, Medionidus walkeri, a federally threatened freshwater mussel species endemic to the Suwannee River basin in Georgia and Florida. We also assessed the influence of survey effort on...

It differs from other congeners by the following combination of characters: posterior end of maxilla strongly hooked; membrane connecting maxilla...

Geochemical characterization of solid media from three watersheds that transect the basal contact of the Duluth Complex, northeastern Minnesota

Laurel G. Woodruff
To document regional water quality in areas of potential base-metal mining, bedrock, soil, streambed sediment, and surface-water samples were collected and analyzed in three watersheds that cross the basal part of the Duluth Complex (northeastern Minnesota). The three watershed each had different mineral-deposit settings: (1) copper-nickel-platinum group element mineralization (Filson Creek), (2) iron-titanium-oxide mineralization (St. Louis River), and (3) no identified mineralization (Keeley Creek). At least 10 bedrock, 30 soil (two from 15 sites), and...

Geospatial dataset of bathymetric survey of the Cayuga Inlet flood-control channel and selected tributaries in Ithaca, New York, 2016

William F. Coon, Elizabeth A. Nystrom & John F. Wernly
From July 14-20, 2016, the U.S. Geological Survey, in cooperation with the City of Ithaca, New York, conducted a bathymetric survey of the Cayuga Inlet flood-control channel and selected mouths of tributaries to Cayuga Inlet and Cayuga Lake in Ithaca, New York. U.S. Geological Survey personnel collected bathymetric data using an acoustic Doppler current profiler. The survey plan produced a dense dataset of water depths that were converted to bottom elevations by subtracting the depths...

Determine the Effect of 35% Peroxaid, Administered to Control Mortality from Saprolegniasis, on the Nitrogen Oxidation Efficiency of the Biofilters of Recirculating Aquaculture Systems for Freshwater Finfish�Field Studies: Data

Kim T Fredricks & Sue M Schleis
This data set is associated with an administrative report submitted to the U.S. Food and Drug Administration Center for Veterinary Medicine (CVM). The project goal was to determine the effects of hydrogen peroxide on the microflora of recirculating aquaculture systems (RAS). There are few aquaculture drugs approved for use in RAS and the CVM will evaluate findings from the study to determine if hydrogen peroxide would be safe to use in RAS.

Unvegetated to vegetated marsh ratio in Plum Island Estuary and Parker River salt marsh complex, Massachusetts

Zafer Defne & Neil Kamal Ganju
Unvegetated to vegetated marsh ratio (UVVR) in the Plum Island Estuary and Parker River (PIEPR) salt marsh complex was computed based on conceptual marsh units defined by Defne and Ganju (2018). UVVR was calculated based on U.S. Department of Agriculture National Agriculture Imagery Program (NAIP) 1-meter resolution imagery. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to...

Vermillion/Cannon River Bottoms Important Bird Area Raw Breeding bird data

Eileen M Kirsch & Brian R Gray
We sampled vegetation and breeding birds in Upper Mississippi River floodplain forest edge and interior areas to (1) measure Phalaris cover and (2) evaluate if the breeding bird assemblage responded to differences in Phalaris cover or other forest structure variables. Data are counts of birds collected during 3 surveys within 50m at each site using 10 minute point count methods. Vegetation was sampled using a releve technique at the bird count point within 10m of...

Climatic controls on the global distribution, abundance, and species richness of mangrove forests

Michael J. Osland, Laura C. Feher & K.T. Griffith
Mangrove forests are highly productive tidal saline wetland ecosystems found along sheltered tropical and subtropical coasts. Ecologists have long assumed that climatic drivers (i.e., temperature and rainfall regimes) govern the global distribution, structure, and function of mangrove forests. However, data constraints have hindered the quantification of direct climate-mangrove linkages in many parts of the world. Recently, the quality and availability of global-scale climate and mangrove data have been improving. Here, we used these data to...

Data Release of the bedrock geology and hydrostratigraphy of the Edwards and Trinity aquifers within the Driftwood and Wimberley 7.5-minute quadrangles, Hays and Comal Counties, Texas

Allan K. Clark & Robert R. Morris
The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area's water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and hydrostratigraphic units (HSUs) of the aquifers are needed. This digital map database presents the...

USGS Measurements of Water Quality in San Francisco Bay (CA), 1969-2015

James E. Cloern & Tara S. Schraga
The U.S. Geological Survey maintains a program of water-quality studies in San Francisco Bay (CA) that began in 1969. We plan a USGS Data Release to archive and make available all measurements made from 1969 through 2015. Water-quality constituents include salinity, temperature, light attenuation coefficient, and concentrations of chlorophyll-a, dissolved oxygen, suspended particulate matter, nitrate, nitrite, ammonium, silicate and phosphate. Water samples are collected at 37 fixed sampling locations along a 145-km transect from lower...

Near-real-time Herbaceous Annual Cover in the Sagebrush Ecosystem, USA, July 2018
