Inorganic and organic chemical composition of groundwater collected from monitoring wells located at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, Minnesota, USA 2009-2023 Inorganic and organic chemical composition of groundwater collected from monitoring wells located at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, Minnesota, USA 2009-2023
This dataset contains information from groundwater monitoring wells at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. The information includes field and laboratory methods, site locations, and inorganic and organic chemistry data. Samples were collected between 2009 and 2023, and analyzed for inorganic anions: F (fluoride), Cl...
Water quality of the Jim Bertram Lake System, Lubbock, Texas: Oct 2021-Oct 2023 Water quality of the Jim Bertram Lake System, Lubbock, Texas: Oct 2021-Oct 2023
Data are found in two separate *.csv files. File 1 contains the data and file 2, the sampling site coordinates. The data describes the results of water quality measurements in the Jim Bertram Lake System, an impounded urban stream system in Lubbock, Texas. Measurements were taken from October 2021 through October 2023.
Streambed and suspended sediment data from streams in western Montana from 2018 Streambed and suspended sediment data from streams in western Montana from 2018
This data release contains streambed sediment data, suspended sediment data, and stream stage data from tributary streams in Western Montana. These datasets were created to assess the linkages between unpaved roads and instream sediment distributions. Surveys were collected in tributaries and rivers within the Clearwater River and Swan River basins in Montana. Site locations were...
Data release: Flood and Storm Tracker (FaST) data Data release: Flood and Storm Tracker (FaST) data
This product summarizes data used in the analysis portion of our Flood and Storm Tracker (FaST) manuscript (see larger work citation). The dataset titled HUCsppMatrices2012-2022.csv has each Hydraulic Unit Code (HUC) with an introduced taxon in each storm and the HUC it connected to by flood waters (lateral or longitudinal). The dataset titled ConnectionPoints_2012-2022.csv has each...
A machine learning approach for discriminating triploid and diploid Grass Carp (Ctenopharyngodon idella) by using microscopic images of hematologically stained blood cells A machine learning approach for discriminating triploid and diploid Grass Carp (Ctenopharyngodon idella) by using microscopic images of hematologically stained blood cells
Microscopic images of hematologically stained whole blood cells from diploid and triploid Grass Carp (Ctenopharynngodon idella) were obtained by a laboratory microscope and field microscope.
Pathological findings by fixative time and formulation for Porites evermanni and Montipora capitata Pathological findings by fixative time and formulation for Porites evermanni and Montipora capitata
Collections for histopathology in corals require holding of samples in seawater for a time before they are fixed for histopathology processing. This could adversely affect interpretation of morphologic changes during histopathology examinations. We evaluated microscopic morphology of Porites evermanni and Montipora capitata, held (0-120 min) in seawater prior to fixation in Z-Fix...
