Arrowweed (Pluchea sericea) morphological and physiological response data from a greenhouse inundation experiment Arrowweed (Pluchea sericea) morphological and physiological response data from a greenhouse inundation experiment
These data were collected to evaluate if arrowweed (Pluchea sericea) individuals and genotypes collected from across a 5.3 degree Celsius temperature gradient and grown in a common greenhouse environment had different physiological and morphological responses to inundation. The objectives of the study were to assess if 1) individuals from climatically different provenances differ in...
Arthropod Abundance and Shrub Cover and Height on the Seward Peninsula, Alaska, 2015-2016 Arthropod Abundance and Shrub Cover and Height on the Seward Peninsula, Alaska, 2015-2016
This data set contains information (in three tables) with numbers and biomass of invertebrates (primarily arthropods) collected in pitfall-trap arrays and sweep-net samples on a series of plots (n = 13 total) at one coastal and one interior study site on the Seward Peninsula in northwestern Alaska during the summers of 2015 and 2016. Associated data on the horizontal cover and height of...
Assessing Exposure, Physiological Effects, and Geographic Scope of Anticoagulant Rodenticides in the Critically Endangered California Condor Assessing Exposure, Physiological Effects, and Geographic Scope of Anticoagulant Rodenticides in the Critically Endangered California Condor
-Test subject identification information (sample collection site and date, test subject identification number, and sample number) -Clotting time parameters and comments (prothrombin time, Russell’s viper venom time, fibrinogen concentration, and coefficient of variation for replicate analyses)
Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs
Using the Hydrodynamic-Marsh Equilibrium Model (Hydro-MEM), the wetlands system within the Apalachicola-Big-Bend region of Florida (FL) (Fig. 1) was assessed using three sea-level rise scenarios of intermediate-low (50 centimeters [cm] by 2100), intermediate (1 meter [m] by 2100), and intermediate-high (1.5 m by 2100) from the National Oceanic and Atmospheric Administration (NOAA). Hydro...
Assessing the Status and Trends of Seabirds and Forage Fish in Lower Cook Inlet, Alaska Assessing the Status and Trends of Seabirds and Forage Fish in Lower Cook Inlet, Alaska
This data release is composed of seven datasets regarding colonial seabirds and forage fish at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska. These data were collected to detect changes in the breeding population of Black-legged Kittiwakes and Common Murres on two nesting colonies in lower Cook Inlet and to compare those counts to baseline counts...
Assessment of Field and Laboratory Methods for the Detection and Analyses of Cyanobacteria and Cyanotoxins in Texas Reservoirs, 2020 Assessment of Field and Laboratory Methods for the Detection and Analyses of Cyanobacteria and Cyanotoxins in Texas Reservoirs, 2020
In cooperation with the Texas Commission on Environmental Quality (TCEQ), the U.S. Geological Survey (USGS) used various field and laboratory methods to determine the presence and concentration of cyanobacteria, cyanotoxins, and taste-and-odor compounds in selected Texas water bodies. This data release documents the results from water-quality samples collected from 12 water bodies in...
Assessment of mercury sources in Alaskan lake food webs (version 1.1, September 2023) Assessment of mercury sources in Alaskan lake food webs (version 1.1, September 2023)
This data release includes results of raw water, soil, seston, and fish tissue samples collected from lakes in southwestern Alaska between 2011 and 2016. Specifically, these data include total mercury and methylmercury concentrations in water, size-sieved seston, and particulate matter of 13 remote lakes. Additionally, these data include soil and volcanic ash measurements from the...

Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database
Seamless topographic-bathymetric (topo-bathy) profiles and their derived morphologic characteristics were developed for sandy coastlines along the Atlantic and Gulf coasts of the United States. The topo-bathy profiles are published as a database in the Hierarchical Data Format version 5 (HDF5) which contain cross-shore distance coordinates, Universal Transverse Mercator (UTM) coordinate...
Attribution of Chessie BIBI and fish sampling data to NHDPlusV2 Catchments within the Chesapeake Bay Watershed Attribution of Chessie BIBI and fish sampling data to NHDPlusV2 Catchments within the Chesapeake Bay Watershed
This data release links fish survey data from a suite of programs in the Chesapeake Bay watershed as well the benthic macroinvertebrate sites included in the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) developed by the Interstate Commission on the Potomac River Basin (ICPRB) and available from the Chesapeake Bay Program. The data set contains site name, survey...
Bacterial Communities Shed by Montastraea cavernosa Coral Fragments into Filtered Seawater Mesocosms-Raw Data Bacterial Communities Shed by Montastraea cavernosa Coral Fragments into Filtered Seawater Mesocosms-Raw Data
The files in this data release contain an amplicon sequence variant (ASV) table and the raw 16S rRNA gene amplicon files from six 0.22-micron size fractions of tangential flow filtration-concentrated microbial communities (Mcav17, Mcav18, McH-101, McH-103, McD-57, and McD-58) derived from mesocosms consisting of filtered seawater in which either healthy or diseased fragments of...
Barataria Basin Landbridge Shoreline Protection, Phases 1, 2, and 3 (BA-27): 2018 land-water classification Barataria Basin Landbridge Shoreline Protection, Phases 1, 2, and 3 (BA-27): 2018 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
