Surface water estimates for a complex study site derived from traditional and emerging methods Surface water estimates for a complex study site derived from traditional and emerging methods

These data describe the area of different habitat covered in water as determined via three approaches: manual surveys, digitized aerial imagery, and categorization of the newly available dynamic surface water extent dataset derived from satellite imagery. These data support a scientific publication.

Surface-water characteristics and phytoplankton taxonomy in selected north Texas reservoirs using biological, hyperspectral, and water-quality methods, 2019-2020 Surface-water characteristics and phytoplankton taxonomy in selected north Texas reservoirs using biological, hyperspectral, and water-quality methods, 2019-2020

A study to develop an earth observation monitoring system to detect harmful algal bloom (HABs) presence within selected north Texas reservoirs using satellite imagery was conducted by the U.S. Geological Survey (USGS). This data release provides the data collected for this study including site locations, water-quality, phytoplankton, and hyperspectral water surface reflectance data. Data...

Surface-Water-Quality Data and Time-Series Plots to Support Implementation of Site-Dependent Aluminum Criteria in Massachusetts, 2018-19 (ver. 1.1, February 2023) Surface-Water-Quality Data and Time-Series Plots to Support Implementation of Site-Dependent Aluminum Criteria in Massachusetts, 2018-19 (ver. 1.1, February 2023)

This data release includes water-quality data collected at 38 sites in central and eastern Massachusetts from April 2018 through May 2019 by the U.S. Geological Survey to support the implementation of site-dependent aluminum criteria for Massachusetts waters. Samples of effluent and receiving surface waters were collected monthly at four wastewater-treatment facilities (WWTFs) and seven...

Surfaces representing the basal mineralized zone in the South Kawishiwi, Bathtub, and Partridge River Intrusions, Duluth Complex, Minnesota Surfaces representing the basal mineralized zone in the South Kawishiwi, Bathtub, and Partridge River Intrusions, Duluth Complex, Minnesota

This dataset includes five Esri grids representing the copper-nickel-platinum group element (Cu-Ni-PGE) mineralized zone found in the South Kawishiwi, Bathtub, and Partridge River intrusions, Duluth Complex, Minnesota. The data are also presented in .csv format to provide an open-source file type. We are using the term "basal mineralized zone" (bmz) as an informal term representing the...

Surficial and Downcore Sedimentological and Foraminiferal Microfossil Data From St. Marks National Wildlife Refuge, Florida Surficial and Downcore Sedimentological and Foraminiferal Microfossil Data From St. Marks National Wildlife Refuge, Florida

In October 2019, five marsh push cores (core names appended with M for marsh push core) and 18 surface sediment samples (top 1 cm of sediment) were collected from the estuary (sample name appended G for PONAR grab) near the mouth of the St. Marks River and some of the surrounding marshes (sample name appended with S for surface) along with elevation transects and peat augers (sample name...

Surrogate regression models for computation of time series suspended-sediment concentrations, Chester County, Pennsylvania (2020) Surrogate regression models for computation of time series suspended-sediment concentrations, Chester County, Pennsylvania (2020)

The U.S. Geological Survey (USGS), in cooperation with the Chester County Water Resources Authority (CCWRA), has collected discrete stream samples for analysis of suspended-sediment concentrations at seven gaging stations where near real-time continuous data on stream discharge, and turbidity have been collected since 2005. Historical regression equations to estimate suspended-sediment

Surveillance and reports of Brown Treesnakes on Saipan, 1980-2020 Surveillance and reports of Brown Treesnakes on Saipan, 1980-2020

Available active surveillance efforts for Brown Treesnakes on the island of Saipan via nocturnal visual encounter surveys and trapping from 1999-2018 were collected and summarized into 3 csv files (TRAP1999, BTSRRTSaipanTRAP, and BTSRRTSaipanVISUAL). Location and date of non-confirmed reports of snakes 1982-2013 via passive surveillance were compiled into a fourth file (Saipan...

Survey of metals in soils and associated endemic plants across the historic Harshaw Mining District, Southern Arizona Survey of metals in soils and associated endemic plants across the historic Harshaw Mining District, Southern Arizona

The legacy of mining exploration and operations can remain for decades to centuries if not treated, posing risks to human and animal health due to fugitive dispersal of metal(loid) laden dust and water. The use of endemic plants is key to the success of phytostabilization because endemics are adapted to the conditions prevailing in local mine sites. To this end, we evaluated the...

Surveyed coordinates and elevations in a 2017 resurvey of previously established cross sections on the Little Snake and Yampa rivers in Lily and Deerlodge parks, Colorado Surveyed coordinates and elevations in a 2017 resurvey of previously established cross sections on the Little Snake and Yampa rivers in Lily and Deerlodge parks, Colorado

These data were compiled for the National Park Service and Upper Colorado River Endangered Fish Recovery Program. Objective(s) of our study were to resurvey previously established cross sections on the Yampa and Little Snake rivers in the Deerlodge Park area to document changes in channel width, depth, and cross-sectional area. A secondary purpose of this study was to document the...

Surveys and Monitoring of Coastal Cactus Wren in Southern San Diego County (ver. 6.0, March 2026) Surveys and Monitoring of Coastal Cactus Wren in Southern San Diego County (ver. 6.0, March 2026)

Data presented are results of surveys and monitoring for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. These data were collected to assess Cactus Wren population status following 3 years of drought and determine the relationships between specific elements of habitat quality, food availability, and Cactus Wren productivity and survival. Surveys were...

Survival and viral load of chinook salmon, sockeye salmon, and steelhead trout exposed to 4 genogroups of infectious hematopoietic necrosis virus (IHNV) Survival and viral load of chinook salmon, sockeye salmon, and steelhead trout exposed to 4 genogroups of infectious hematopoietic necrosis virus (IHNV)

Theory of the evolution of pathogen specialization suggests that a specialist pathogen gains high fitness in one host, but this comes with fitness loss in other hosts. By contrast, a generalist pathogen does not achieve high fitness in any host, but gains ecological fitness by exploiting different hosts, and has higher fitness than specialists in non-specialized hosts. As a result...
